Preventing irrelevant Google Ads from showing up on your web page
If you do not want to show specific Google ads from your blog you could use the “Competitive Ad Filter” that can be used to block ads from specific URLs. For example, you could specify to block ads from example.com or blog.example.com.
While this feature is handy it may cause problems if you have multiple sites. For example, in my blog (TechThinker.com) I would like to see Google ads related to the topic of blogging. But in my wife’s new blog I do not want to see any Google ads related to blogging. My wife’s blog is called “BabyTipsBlog” and on the front page of this blog Google ads relating to the topic of blogging are displayed. I think this is happening because the word “blog” is part of the domain name as well as the blog name.
If I try to block blogging related ads from my wife’s blog (using the Competitive Ads Filter) I will end up blocking these ads on my blog as well because both the blogs share the same Adsense publisher Id.
From the above example, you can see that using the Competitive Ad Filter could cause conflicts if you have multiple websites or blogs.
The remedy to the above problem is to use section targeting. Using section targeting you can specify which sections in your page should be given importance by Google. You can also specify which sections should be ignored.
Here’s a code snippet that shows you how to use section targeted Google ads.
<html>
<head>
…
</head>
<body>
…
<!– google_ad_section_start –>
Adsense will consider this ection to be very important.
<!– google_ad_section_end –>
…
<!– google_ad_section_start(weight=ignore) –>
Adsense will ignore this section.
<!– google_ad_section_end –>
…
</body>
</html>
Using section targeting you can show more relevant ads on your webpage. Showing relevant ads will naturally increase your click through rate resulting in higher revenue.

Thats a really great tip that I’m actually going to use. I know that Google takes into account the content around the ad placement, but it’s nice to be able to specifically target different areas.
