Don’t you hate it when a ad unrelated to your website’s topic fills up your entire adsense ad block? Then you load the page again and you see that same stupid ad? Well you can get rid of it using the competitive ad filter. The ad filter will block out ads from that domain. If you just leave it there, you will be losing potential click money by having an unrelated ad that chances are, your visitor won’t click on. Adsense is all about contextual ad targeting, if the ad doesn’t fit your website at all, get rid of it or you will be losing click revenue.

There is another reason to use the filter. Many websites called MFA (Made for Ads), purposely target unrelated keywords. They buy very low priced keywords in order for a visitor to go and click on their higher paying keywords. This process is called Adsense arbitrage and is now frowned upon by Google.

These MFA ads are low paying, so you must eliminate them in order to keep your pay per click rate high overall. There is plenty that still break the rules and it’s important you stay on top of it. A tipoff to a possible MFA site is a long or odd domain name or unrelated domain name or description to the title of the ad. If you want to doublecheck the site, just type in the url from the ad in a new browser window. Google only allows you to block up to 200 domains simultaneously. To get around this 200 limit, when you reach 200, you might want to erase and start over every 6 months to a year because they often use different sites over time anyways.

To add it, log in to your adsense account. Then go to adsense setup. Click on the competitive ad filter tab. Enter the domain of the ad and it should take about 1 day for it to be blocked.
