How do I avoid the Google Slap?

And the best suggestions for this is?

Hi Dayne,

The "Google Slap" is a warning that you have quality score issues. For an overview on Landing page and Site Quality guidelines, see this link:

When using a single page sales letter there are a few things you need to be concerned about. As Gauher pointed out you need: contact us, privacy policy, TOS and Site map pages.

Sometimes a really long sales letter will fill the need of sufficient content. In many cases, you need to link to other sites to fill the gap. I usually build all these necessary links into a very small unobtrusive footer. This way it doesn't get in the way of your marketing efforts. This works great, by the way, on squeeze pages.

You really need to study Google's Webmaster Guidelines and realize every single word in there is very important. Google hired linguists, attorneys and scientist to pour over every word to decide if it was really necessary.

Here is a link that breaks it down nicely:

Ps. I forgot to mention the Keyword Analysis Page. This handy feature will tell you in general terms what is causing Quality Score issues on a keyword by keyword basis. Pay close attention to your keyword's quality score and use this tool when you have a problem.

Also learn how to setup and structure your campaigns so they improve your individual keyword quality scores. Most importantly small tightly focused ad groups, the smaller the better.
