How to Erase Low CPC Advertisers From Google AdSense

1. Survey the ads on your site. Visit your website and view the ads that are being shown on your pages. Make a note of the ad subject and URL that is displayed with each ad.
2. Identify potential low CPC ads. Using Google's free keyword research tool, or the keyword tool of your choice, evaluate the value of ads relating to the subjects you noted. You can enter a keyword phrase similar to the subject of the ad and see what CPC value is associated with that phrase. Although not an absolute measure of the ad value, this will give you some indication of the relative value of the ad in terms of CPC. Note the ad subjects that have a low CPC relative to the others.

3. List non-relevant or competing ads. In addition to evaluating the ad subject value, you will also want to identify ads that are not relevant to your site topic or competitor ads. By restricting these ads from being displayed, you can possibly increase your ad revenue and retain more visitors on your site.
4. Log into your AdSense account.
5. Click the tab for AdSense setup. Select the 'Competitive Ad Filter' menu link.
6. Click the 'AdSense for Content' tab.
7. Enter the URLs of the ads you want to block. Once you've entered the URLs, press the 'Save Changes' button.
