Google obviously has a right to determine which pages represent the greatest quality and most match to keywords, but in 2008, a round of Google Slap actions on small vendors took considerable toll, driving many companies out of business quickly. Many argued that their pages conformed to Google’s AdWords recommendations for pages, and yet they still receive very low PR rankings. This meant the enormously high pay per click fees were prohibitive, and comparable to banning certain vendors from using AdWords, though searches for information on these pages might still be revealed in a regular Google search, just not in ads.
When some companies receive a Google Slap, just about the only thing they can do is completely change their domain because it is very difficult to challenge Google on their ratings or assessment of pages. There are Internet horror stories on known pages, with excellent authoritative and original information being slapped, and being unable to recover. If you decide Google AdWords is for you, you should definitely read all information about what Google looks for to avoid receiving a Google Slap.
A few things that Google consistently appears to look for include original and significant content on landing pages (the page a person goes to when they click on your ad), transparent business dealings and upfront information about how you conduct business, and easy methods for searching your website from the landing page. To avoid a Google Slap you’ll want to not create a landing page that is just a table of contents and plenty of ads for other vendors, and you have to make sure your page conforms to any of Google’s Editorial Guidelines, too.
