Dynamic content used to be a red flag for search engine friendly design

Dynamic content used to be a red flag for search engine friendly design, but times have changed. Search engines now include dynamically-generated pages in their indexes, but some particulars of dynamic pages can still be obstacles to getting indexed. Whether it’s keeping in synch with inventory or updating a blog, more than likely if you’re a website owner you have some level of dynamic or CMS-managed content on your site (and if not, you should really be looking into it for your next redesign). Follow the guidelines here to avoid major pitfalls and ensure that your dynamic body of work is search engine friendly from head to toe.

Rule 1: Be sure that search engines can follow regular HTML links to all pages on your site.

Any website needs individually linkable URLs for all unique pages on the site. This way every page can be bookmarked and deep linked by users, and indexed by search engines. But dynamic websites have an additional concern: making sure the search engine robots can reach all of these pages.

For example, suppose you have a form on your website: you ask people to select their location from a pull-down, and then when people submit the form your website generates a page with content that is specifically written for that geographical area. Search engine robots don't fill out forms or select from pull-down menus, so there will be no way for them to get to that page.

This problem can be easily remedied by providing standard type HTML links that point to all of your dynamic pages. The easiest way to do this is to add these links to your site map.

Rule 2: Set up an XML site map if you can’t create regular HTML links to all of your pages, or if it appears that search engines are having trouble indexing your pages.

If you have a large (10K pages or more) dynamic site, or you don’t think that providing static HTML links is an option, you can use an XML site map to tell search engines the locations of all your pages.

Most website owners tell Google and Yahoo! about their site maps through the search engines' respective webmaster tools (Links: Google Yahoo!). But if you're an early adopter, you should look into the new system whereby a site map can be easily designated in the robots.txt file using sitemap autodiscovery. Ask.com, Google and Yahoo! currently support this feature. Cool!

Rule 3: If you must use dynamic URLs, keep them short and tidy

Another potential problem - and this is one that is subject to some debate - is with dynamic pages that have too many parameters in the URL. Google itself in its webmaster guidelines states the following: "If you decide to use dynamic pages (i.e., the URL contains a "?" character), be aware that not every search engine spider crawls dynamic pages as well as static pages. It helps to keep the parameters short and the number of them few."

Here are a few guidelines you should follow for your website parameters:

Limit the number of parameters in the URL to a maximum of 2

Use the parameter "?id=" only when in reference to a session id

Be sure that the URL functions if all dynamic items are removed

Be sure your internal links are consistent - always link with parameters in the same order and format

Rule 4: Avoid dynamic-looking URLs if possible

Besides being second-class citizens of search, dynamic-looking URLs are also less attractive to your human visitors. Most people prefer to see URLs that clearly communicate the content on the page. Since reading the URL is one of the ways that people decide whether to click on a listing in search engines, you are much better off having a URL that looks like this:

rather than this:

We also think that static-looking, “human-readable” URLs are more likely to receive inbound links, because some people will be less inclined to link to pages with very long or complicated URLs.

Furthermore, keywords in a URL are a factor, admittedly not a huge one, in search engine ranking algorithms. Notice how, in the above example, the static URL contains the keywords “discount” and “church bells” while the dynamic URL does not.

There are many tools available that will re-create a dynamic site in static form. There are also tools that will re-write your URLs, if you have too many parameters, to "look" like regular non-dynamic URLS. We think these are both good options for dynamic Intrapromote has a helpful post on dynamic URL rewriting.

Rule 5: De-index stubs and search results

Have you heard of “website stubs?” These are pages that are generated by dynamic sites but really have no independent content on them. For example, if your website is a shopping cart for toys, there may be a page generated for the category “Age 7-12 Toys” but you may not actually have any products in this category. Stub pages are very annoying to searchers, and search engines, by extension, would like to prevent them from displaying in their results. So do us all a favor and either figure out a way to get rid of these pages, or exclude them from indexing using the robots.txt file or robots meta tag.

Search results from within your website is another type of page for which Google has stated a dislike: “Typically, web search results don’t add value to users, and since our core goal is to provide the best search results possible, we generally exclude search results from our web search index.” Here’s our advice: either make sure your search results pages add value for the searcher (perhaps by containing some unique content related to the searched term), or exclude them from indexing using the robots.txt file or robots meta tag.

Bonus Points: Handling duplicate content

While it's not a problem that's specific to dynamic sites, this rule is one that dynamic sites are more likely to break than static ones. If multiple pages on your site display materials that are identical or nearly identical, duplicates should be excluded from indexing using the robots.txt file or a robots meta tag. Think of it this way: you don’t want all your duplicate pages competing with each other on the search engines. Choose a favorite, and exclude the rest. [Editor's note: we no longer (2009) recommend de-indexing duplicate content. A better approach is to either redirect your duplicate pages to the primary page using a server-side, 301 redirect, or to set up a tag for any page that has been duplicated. A good explanation of best practices for handling duplicate content in 2009 can be found at Matt Cutts' Blog]

Dynamic content is usually timely and useful, which is why users love it, and the search engines want to list it. And now you know how to help your dynamic website reach its full search engine potential.

Web Crawling

When most people talk about Internet search engines, they really mean World Wide Web search engines. Before the Web became the most visible part of the Internet, there were already search engines in place to help people find information on the Net. Programs with names like "gopher" and "Archie" kept indexes of files stored on servers connected to the Internet, and dramatically reduced the amount of time required to find programs and documents. In the late 1980s, getting serious value from the Internet meant knowing how to use gopher, Archie, Veronica and the rest.

Today, most Internet users limit their searches to the Web, so we'll limit this article to search engines that focus on the contents of Web pages.

Before a search engine can tell you where a file or document is, it must be found. To find information on the hundreds of millions of Web pages that exist, a search engine employs special software robots, called spiders, to build lists of the words found on Web sites. When a spider is building its lists, the process is called Web crawling. (There are some disadvantages to calling part of the Internet the World Wide Web -- a large set of arachnid-centric names for tools is one of them.) In order to build and maintain a useful list of words, a search engine's spiders have to look at a lot of pages.

How does any spider start its travels over the Web? The usual starting points are lists of heavily used servers and very popular pages. The spider will begin with a popular site, indexing the words on its pages and following every link found within the site. In this way, the spidering system quickly begins to travel, spreading out across the most widely used portions of the Web.

Google began as an academic search engine. In the paper that describes how the system was built, Sergey Brin and Lawrence Page give an example of how quickly their spiders can work. They built their initial system to use multiple spiders, usually three at one time. Each spider could keep about 300 connections to Web pages open at a time. At its peak performance, using four spiders, their system could crawl over 100 pages per second, generating around 600 kilobytes of data each second.

Keeping everything running quickly meant building a system to feed necessary information to the spiders. The early Google system had a server dedicated to providing URLs to the spiders. Rather than depending on an Internet service provider for the domain name server (DNS) that translates a server's name into an address, Google had its own DNS, in order to keep delays to a minimum.

When the Google spider looked at an HTML page, it took note of two things:

The words within the page
Where the words were found
Words occurring in the title, subtitles, meta tags and other positions of relative importance were noted for special consideration during a subsequent user search. The Google spider was built to index every significant word on a page, leaving out the articles "a," "an" and "the." Other spiders take different approaches.

These different approaches usually attempt to make the spider operate faster, allow users to search more efficiently, or both. For example, some spiders will keep track of the words in the title, sub-headings and links, along with the 100 most frequently used words on the page and each word in the first 20 lines of text. Lycos is said to use this approach to spidering the Web.

Other systems, such as AltaVista, go in the other direction, indexing every single word on a page, including "a," "an," "the" and other "insignificant" words. The push to completeness in this approach is matched by other systems in the attention given to the unseen portion of the Web page, the meta tags. Learn more about meta tags on the next page.

What is Robot.txt file & How to Use it?

Web site owners use the /robots.txt file to give instructions about their site to web robots; this is called The Robots Exclusion Protocol.

It works likes this: a robot wants to vists a Web site URL, say http://www.example.com/index.html. Before it does so, it firsts checks for http://www.example.com/robots.txt, and finds:

User-agent: *
Disallow: /

The "User-agent: *" means this section applies to all robots.

The "Disallow: /" tells the robot that it should not visit any pages on the site.

There are two important considerations when using /robots.txt:
• robots can ignore your /robots.txt. Especially malware robots that scan the web for security vulnerabilities, and email address harvesters used by spammers will pay no attention.
• the /robots.txt file is a publicly available file. Anyone can see what sections of your server you don't want robots to use.
So don't try to use /robots.txt to hide information.

See also:

• Can I block just bad robots?
• Why did this robot ignore my /robots.txt?
• What are the security implications of /robots.txt?

The details

The /robots.txt is a de-facto standard, and is not owned by any standards body. There are two historical descriptions:

• the original 1994 A Standard for Robot Exclusion document.
• a 1997 Internet Draft specification A Method for Web Robots Control

In addition there are external resources:

• HTML 4.01 specification, Appendix B.4.1
• Wikipedia - Robots Exclusion Standard

The /robots.txt standard is not actively developed. See What about further development of /robots.txt? for more discussion.

The rest of this page gives an overview of how to use /robots.txt on your server, with some simple recipes. To learn more see also the FAQ.

How to create a /robots.txt file
Where to put it
The short answer: in the top-level directory of your web server.
The longer answer:
When a robot looks for the "/robots.txt" file for URL, it strips the path component from the URL (everything from the first single slash), and puts "/robots.txt" in its place.

For example, for "http://www.example.com/shop/index.html, it will remove the "/shop/index.html", and replace it with "/robots.txt", and will end up with "http://www.example.com/robots.txt".

So, as a web site owner you need to put it in the right place on your web server for that resulting URL to work. Usually that is the same place where you put your web site's main "index.html" welcome page. Where exactly that is, and how to put the file there, depends on your web server software.
Remember to use all lower case for the filename: "robots.txt", not "Robots.TXT.

See also:

What program should I use to create /robots.txt?
How do I use /robots.txt on a virtual host?
How do I use /robots.txt on a shared host?
What to put in it The "/robots.txt" file is a text file, with one or more records. Usually contains a single record looking like this:

User-agent: *
Disallow: /cgi-bin/
Disallow: /tmp/
Disallow: /~joe/

In this example, three directories are excluded.

Note that you need a separate "Disallow" line for every URL prefix you want to exclude -- you cannot say "Disallow: /cgi-bin/ /tmp/" on a single line. Also, you may not have blank lines in a record, as they are used to delimit multiple records.

Note also that globbing and regular expression are not supported in either the User-agent or Disallow lines. The '*' in the User-agent field is a special value meaning "any robot". Specifically, you cannot have lines like "User-agent: *bot*", "Disallow: /tmp/*" or "Disallow: *.gif".

What you want to exclude depends on your server. Everything not explicitly disallowed is considered fair game to retrieve. Here follow some examples:

To exclude all robots from the entire server
User-agent: *
Disallow: /

To allow all robots complete access
User-agent: *
(or just create an empty "/robots.txt" file, or don't use one at all)

To exclude all robots from part of the server
User-agent: *
Disallow: /cgi-bin/
Disallow: /tmp/
Disallow: /junk/

To exclude a single robot
User-agent: BadBot
Disallow: /

To allow a single robot
User-agent: Google

User-agent: *
Disallow: /

To exclude all files except one
This is currently a bit awkward, as there is no "Allow" field. The easy way is to put all files to be disallowed into a separate directory, say "stuff", and leave the one file in the level above this

User-agent: *
Disallow: /~joe/stuff/

Alternatively you can explicitly disallow all disallowed pages:

User-agent: *
Disallow: /~joe/junk.html
Disallow: /~joe/foo.html
Disallow: /~joe/bar.html

How XML sitemap is useful in Search Engine Optimization?

Search engine sitemaps are organized structures of websites' pages, usually useful to search engines for better content indexing. A search engine sitemap (meant only for search engines to see) is a tool provided by Google, Yahoo!, and MSN to allow webmasters to suggest how often, and in what order, a search engine should spider each page within their websites.

Google Sitemaps has become a popular tool in the world of webmasters. The service helps them continually submit fresh content to the search engine.

How to build Sitemaps?

 Creating a search engine sitemap is quite simple thanks to a free online tool atXML-Sitemaps.com that will automatically spider your website and create the sitemap for you. They offer up to 500 webpages maximum spidered for free.

Alternative tools :

1. Simply create a sitemap with the free Search Engine Sitemap Generatorand upload it to your  server.
2. The Google Sitemap Generator is an open source online application that can help you build a  sitemap from scratch. It's a Python script that creates valid search engine sitemaps for your sites using the Sitemap protocol.

Upload the generated script (say sitemap.xml) to your Web site, and tell Google how to find it. Note the file name, and which URL you will use to find it. If you upload it to the root of your domain, then it will be http://www.seo-expert-gaurav.blogspot.com/sitemap.xml.

Now log into your Google sitemap account (Google Webmaster Tools), and point Google to the sitemap stored on your site, using the URL that you already know.

Should you get stuck at any point, feel free to browse through Google's official documentation and tutorials on the subject at Using the Sitemap Generator.

Advantages of search engine site map :

The advantage of Search Engine Sitemaps (or XML sitemaps) over a normal “page of links” sitemap is that you can:

1. Specify the priority of pages to be crawled and/or indexed.
2. Exclude lower priority pages.
3. Insure that Search Engines know about every page on your website.

Until today, only Google, Yahoo and MSN supported this protocol. Today however, there is a new member to the family. Ask.com.

No longer! Vanessa announced that all Search Engines have now agreed to accept Sitemap submissions through the robots.txt file on your server.

The robots.txt file is a Search Engine industry standard file that is the VERY FIRST file a LEGIT Search Engine will view when it first comes to your website. Now, you can simply add your sitemap URL to this file in the form of:
Sitemap: http://www.seo-expert-gaurav.blogspot.com/sitemap.xml

Simply create a sitemap with the free Search Engine Sitemap Generator and upload it to your server. Then open the robots.txt file on your server and add the address as above. This makes it as simple as ever to insure that all Search Engines know about your site, know about what pages are in your site and know what pages of your site to list in the search results.

How to Check Your Google Sitemap Reports :

Google will identify any errors in your site and publish the results to you in the form of a report.
Setps to check sitemap report:
1. Visit the Google Web master tools section of the site. This can be found at www.google.com/webmasters.
2. Add your site to Google if you haven't already done so.
3. Verify that you are the site's owner by either uploading an HTML file to your site or adding a Meta tag.
4. View the statistics and report that Google has already generated about your sitemap. It details the last time the spider went to your page. If your site is not new, then chances are Google has already crawled your site.
5. Change the option to "Enable Google Page Rank" when prompted in the install process of the program. Then hit Finish and wait.
6. Click the Add sitemap link to create a new Google sitemap.
7. Enter your sitemap to tell Google all about your pages.
8. Visit again to view the reports on your pages.

What is back link or inbound links ??

Back links are link to a website or web page. Inbound links were originally important (prior to the emergence of search engines) as a primary means of web navigation; today their significance lies in search engine optimization (SEO). The number of backlinks is one indication of the popularity or importance of that website or page (for example, this is use by Google to determine the PageRank of a webpage). Outside of SEO, the backlinks of a webpage may be of significant personal, cultural or semantic interest: they indicate who is paying attention to that page.

In basic link terminology, a backlink is any link received by a web node (web page, directory, website, or top level domain) from another web node [1]. Backlinks are also known asincoming links, inbound links, inlinks, and inward links.

[edit]Search engine rankings
Search engines often use the number of backlinks that a website has as one of the most important factors for determining that website's search engine ranking, popularity and importance. Google's description of their PageRank system, for instance, notes that Google interprets a link from page A to page B as a vote, by page A, for page B.[2] Knowledge of this form of search engine rankings has fueled a portion of the SEO industry commonly termed linkspam, where a company attempts to place as many inbound links as possible to their site regardless of the context of the originating site.

Websites often employ various techniques (called search engine optimization, usually shortened to SEO) to increase the number of backlinks pointing to their website. Some methods are free for use by everyone whereas some methods like linkbaiting requires quite a bit of planning and marketing to work. Some websites stumble upon "linkbaiting" naturally; the sites that are the first with a tidbit of 'breaking news' about a celebrity are good examples of that. When "linkbait" happens, many websites will link to the 'baiting' website because there is information there that is of extreme interest to a large number of people.

There are several factors that determine the value of a backlink. Backlinks from authoritative sites on a given topic are highly valuable.[3] If both sites have content geared toward the keyword topic, the backlink is considered relevant and believed to have strong influence on the search engine rankings of the webpage granted the backlink. A backlink represents a favorable 'editorial vote' for the receiving webpage from another granting webpage. Another important factor is the anchor text of the backlink. Anchor text is the descriptive labeling of the hyperlink as it appears on a webpage. Search engine bots (i.e., spiders, crawlers, etc.) examine the anchor text to evaluate how relevant it is to the content on a webpage. Anchor text and webpage content congruency are highly weighted in search engine results page (SERP) rankings of a webpage with respect to any given keyword query by a search engine user.

Increasingly, inbound links are being weighed against link popularity and originating context. This transition is reducing the notion of one link, one vote in SEO, a trend proponents[who?]hope will help curb linkspam as a whole.

It should also be noted that building too many Backlinks over a short period of time can get a website's ranking penalized, and in extreme cases, the website is de-indexed altogether. Anything above a couple of hundred a day is considered "dangerous".

When HTML (Hyper Text Markup Language) was designed, there was no explicit mechanism in the design to keep track of backlinks in software, as this carried additional logistical and network overhead.
Some website software internally keeps track of backlinks. Examples of this include most wiki and CMS software.

Most commercial search engines provide a mechanism to determine the number of backlinks they have recorded to a particular web page. For example, Google can be searched usinglink:wikipedia.org to find the number of pages on the Web pointing to http://wikipedia.org/. Google only shows a small fraction of the number of links pointing to a site. It credits many more backlinks than it shows for each website.
Other mechanisms have been developed to track backlinks between disparate webpages controlled by organizations that aren't associated with each other. The most notable example of this is TrackBacks between blogs.

Page Rank Based On Popularity

The web search technology offered by Google is often the technology of choice of the world’s leading portals and websites. It has also benefited the advertisers with its unique advertising program that does not hamper the web surfing experience of its users but still brings revenues to the advertisers.

When you search for a particular keyword or a phrase, most of the search engines return a list of page in order of the number of times the keyword or phrase appears on the website. Google web search technology involves the use of its indigenously designed Page Rank Technology and hypertext-matching analysis which makes several instantaneous calculations undertaken without any human intervention. Google’s structural design also expands simultaneously as the internet expands.

Page Rank technology involves the use of an equation which comprises of millions of variables and terms and determines a factual measurement of the significance of web pages and is calculated by solving an equation of 500 million variables and more than 3 billion terms. Unlike some other search engines, Google does not calculate links, but utilizes the extensive link structure of the web as an organizational tool. When the link to a Page, let’s say Page B is clicked from a Page A, then that click is attributed as a vote towards Page B on behalf of Page A.

GOOGLE Algorithm Is Key

Google has a comprehensive and highly developed technology, a straightforward interface and a wide-ranging array of search tools which enable the users to easily access a variety of information online.

Google users can browse the web and find information in various languages, retrieve maps, stock quotes and read news, search for a long lost friend using the phonebook listings available on Google for all of US cities and basically surf the 3 billion odd web pages on the internet! Google boasts of having world’s largest archive of Usenet messages, dating all the way back to 1981.

Google’s technology can be accessed from any conventional desktop PC as well as from various wireless platforms such as WAP and i-mode phones, handheld devices and other such Internet equipped gadgets.

Vital Benefits of SEO

Selecting search engine optimization for promoting your business on the internet, one must knows the ultimate benefits of seo campaign.

Perspective (Global / Regional)
Selecting your keywords or phrases to target your audience, search engine optimization ensures that you and your company are found globally or regionally by those who require exactly what you offer. SEO has many benefits for any organization which wants to reach all potential customers locally or globally. You can reach the targeted customers of your own choice.

Targeted Traffic
Search engine optimization campaign can increase the number of visitors for your website for the targeted keyword(s) or phrase. Converting those visitors into potential customers is one of the arts of search engine optimization. Search engine optimization is the only campaign which can derive targeted traffic through your website. Essentially more targeted traffic equal more sales.

Increase Visibility
Once a website has been optimized, it will increase the visibility of your website in search engines. More people will visit your website and it will give international recognition to your products/services.

High ROI (Return on Investment)
An effective SEO campaign can bring a higher return on your investment than any other type of marketing for your company. This will therefore increase your volume of sales and profit overall.

Long term positioning
Once a website obtains position through a SEO campaign, it should stay there for long term as opposed to PPC (Pay Per Click). SEO is a cheaper and long term solution than any other search engine marketing strategy.

One of the great benefits of search engine optimization is that it is cost effective and requires the minimum amount of capital for the maximum exposure of your website.

It is possible to reach an audience of your own choice through a seo campaign. You can get traffic according to the organizational strategy to meet the needs and requirements of your choice.

Measurable results
It is a unique quality of seo campaigns that you can quantify the results of seo by positioning reports of search engines, visitor conversion and the other factors of this nature.

Types of Search Engines

Three Types of Search Engines

 The term "search engine" is often used generically to describe crawler-based search engines, human-powered directories, and hybrid search engines. These types of search engines gather their listings in different ways, through crawler-based searches, human-powered directories, and hybrid searches.

Crawler-based search engines

 Crawler-based search engines, such as Google (http://www.google.com), create their listings automatically. They "crawl" or "spider" the web, then people search through what they have found. If web pages are changed, crawler-based search engines eventually find these changes, and that can affect how those pages are listed. Page titles, body copy and other elements all play a role.

The life span of a typical web query normally lasts less than half a second, yet involves a number of different steps that must be completed before results can be delivered to a person seeking information. The following graphic (Figure 1) illustrates this life span (from http://www.google.com/corporate/tech.html):

1. The web server sends the query to the index servers. The content inside the index servers is similar to the index in the back of a book - it tells which pages contain the words that match the query.

2. The query travels to the doc servers, which actually retrieve the stored documents. Snippets are generated to describe each search result.

3. The search results are returned to the user in a fraction of a second.      

Human-powered directories

 A human-powered directory, such as the Open Directory Project (http://www.dmoz.org/about.html) depends on humans for its listings. (Yahoo!, which used to be a directory, now gets its information from the use of crawlers.) A directory gets its information from submissions, which include a short description to the directory for the entire site, or from editors who write one for sites they review. A search looks for matches only in the descriptions submitted. Changing web pages, therefore, has no effect on how they are listed. Techniques that are useful for improving a listing with a search engine have nothing to do with improving a listing in a directory. The only exception is that a good site, with good content, might be more likely to get reviewed for free than a poor site.

Hybrid search engines

 Today, it is extremely common for crawler-type and human-powered results to be combined when conducting a search. Usually, a hybrid search engine will favor one type of listings over another. For example, MSN Search (http://www.imagine-msn.com/search/tour/moreprecise.aspx) is more likely to present human-powered listings from LookSmart (http://search.looksmart.com/). However, it also presents crawler-based results, especially for more obscure queries.

How Google Works??

The technology behind Google's great results

As a Google user, you're familiar with the speed and accuracy of a Google search. How exactly does Google manage to find the right results for every query as quickly as it does? The heart of Google's search technology is PigeonRank™, a system for ranking web pages developed by Google founders Larry Page and Sergey Brin at Stanford University.

Building upon the breakthrough work of B. F. Skinner, Page and Brin reasoned that low cost pigeon clusters (PCs) could be used to compute the relative value of web pages faster than human editors or machine-based algorithms. And while Google has dozens of engineers working to improve every aspect of our service on a daily basis, PigeonRank continues to provide the basis for all of our web search tools.

Why Google's patented PigeonRank™ works so well

PigeonRank's success relies primarily on the superior trainability of the domestic pigeon (Columba livia) and its unique capacity to recognize objects regardless of spatial orientation. The common gray pigeon can easily distinguish among items displaying only the minutest differences, an ability that enables it to select relevant web sites from among thousands of similar pages.

By collecting flocks of pigeons in dense clusters, Google is able to process search queries at speeds superior to traditional search engines, which typically rely on birds of prey, brooding hens or slow-moving waterfowl to do their relevance rankings.

When a search query is submitted to Google, it is routed to a data coop where monitors flash result pages at blazing speeds. When a relevant result is observed by one of the pigeons in the cluster, it strikes a rubber-coated steel bar with its beak, which assigns the page a PigeonRank value of one. For each peck, the PigeonRank increases. Those pages receiving the most pecks, are returned at the top of the user's results page with the other results displayed in pecking order.


Google's pigeon-driven methods make tampering with our results extremely difficult. While some unscrupulous websites have tried to boost their ranking by including images on their pages of bread crumbs, bird seed and parrots posing seductively in resplendent plumage, Google's PigeonRank technology cannot be deceived by these techniques. A Google search is an easy, honest and objective way to find high-quality websites with information relevant to your search.

PigeonRank Frequently Asked Questions

How was PigeonRank developed?

The ease of training pigeons was documented early in the annals of science and fully explored by noted psychologist B.F. Skinner, who demonstrated that with only minor incentives, pigeons could be trained to execute complex tasks such as playing ping pong, piloting bombs orrevising the Abatements, Credits and Refunds section of the national tax code.

Brin and Page were the first to recognize that this adaptability could be harnessed through massively parallel pecking to solve complex problems, such as ordering large datasets or ordering pizza for large groups of engineers. Page and Brin experimented with numerous avian motivators before settling on a combination of linseed and flax (lin/ax) that not only offered superior performance, but could be gathered at no cost from nearby open space preserves. This open space lin/ax powers Google's operations to this day, and a visit to the data coop reveals pigeons happily pecking away at lin/ax kernels and seeds.

What are the challenges of operating so many pigeon clusters (PCs)?

Pigeons naturally operate in dense populations, as anyone holding a pack of peanuts in an urban plaza is aware. This compactability enables Google to pack enormous numbers of processors into small spaces, with rack after rack stacked up in our data coops. While this is optimal from the standpoint of space conservation and pigeon contentment, it does create issues during molting season, when large fans must be brought in to blow feathers out of the data coop. Removal of other pigeon byproducts was a greater challenge, until Page and Brin developed groundbreaking technology for converting poop to pixels, the tiny dots that make up a monitor's display. The clean white background of Google's home page is powered by this renewable process.

Aren't pigeons really stupid? How do they do this?

While no pigeon has actually been confirmed for a seat on the Supreme Court, pigeons are surprisingly adept at making instant judgments when confronted with difficult choices. This makes them suitable for any job requiring accurate and authoritative decision-making under pressure. Among the positions in which pigeons have served capably are replacement air traffic controllers, butterfly ballot counters and pro football referees during the "no-instant replay" years.

Where does Google get its pigeons? Some special breeding lab?

Google uses only low-cost, off-the-street pigeons for its clusters. Gathered from city parks and plazas by Google's pack of more than 50 Phds (Pigeon-harvesting dogs), the pigeons are given a quick orientation on web site relevance and assigned to an appropriate data coop.

Isn't it cruel to keep pigeons penned up in tiny data coops?

Google exceeds all international standards for the ethical treatment of its pigeon personnel. Not only are they given free range of the coop and its window ledges, special break rooms have been set up for their convenience. These rooms are stocked with an assortment of delectable seeds and grains and feature the finest in European statuary for roosting.
