Google AdSense

Helping AdSense Show Relevant Ads On Your Site

One of our sites shows completely unrelated AdSense ads at times. Part of the problem is a single irrelevant keyword. Googlebot finds over 100 total keywords but fell in love with one bad one for some reason. It is only in the content twice, compared to dozens of times for the relevant keywords, but Google does not seem to care. I do not want to change the content because it makes sense to a human.

Fortunately, the AdSense Help Center shows how to filter away keywords so there is a way around this. What I did was tell it when to stop looking for content by doing this in the HTML:


<!-- google_ad_section_start(weight=ignore) -->
content
<!-- google_ad_section_end -->


This is similar to using negative keywords in an AdWords PPC campaign to filter out searches where you do not want your ad to show. You can also tell Google when to start looking for your content by doing this in your HTML instead:


<!-- google_ad_section_start -->
content
<!-- google_ad_section_end -->


It will take a little while for this to take effect but hopefully it solves one of problems with irrelevant ads. Maybe everyone already knows this, but it is a neat little trick.
