Sometimes Google adsense displays non relevant ads in your blog or website. This is one of the common complaints about Adsense that the ads displayed are not relevant to the website’s content. Basically AdSense program enables website publishers to display relevant Google ads and earn. Non-targeted ads will annoy your readers and also reduce your earning potential as your readers may not interested in the ads displayed.
To overcome this issue, Google has a feature called section targeting. This is the simple way to improve your Adsense targeting.
Here is the quote from the Adsense Help Center about section targeting:
Section targeting allows you to suggest sections of your text and HTML content that you’d like us to emphasize or downplay when matching ads to your site’s content. By providing us with your suggestions, you can assist us in improving your ad targeting.
It’s simple to implement Section Targeting, you have to place a HTML tag before and after the content that you want adsense ads to be targeted.
<!– google_ad_section_start –>
YOUR CONTENT FOR SECTION TARGETING GOES HERE.
Most of your website main content resides here.
<!– google_ad_section_end –>
How to Ignore Section Targeting
You can mark sections that you want adsense ignore section targetting (content to be weighted less, ex RSS Web Feeds, sidebar links, etc.,)
<!– google_ad_section_start(weight=ignore) –>
IGNORE. This content is weighted less.
<!– google_ad_section_end –>
You have to use this feature carefully, make sure you start and close the tag properly. Also, you cannot manipulate the section ad targeting by placing insignificant content, as it is against adsense program policies.
