Competitive Ads Filter is a function in Google Adsense that enables you to lock specific ads, such as competitors’ ads from appearing on your pages. Google allows you to enter up to 200 URLs.
Why Competitive Ads Filter
Most webmaster and bloggers doesn’t realize that by not setting that, they are actually losing a lot of their earnings to MFA (Make for Adsense) sites and Arbitragers. This means you can actually earn more, but a fat percent of your potential earnings has gone to MFA & Arbitrages.
What Exactly Are MFA (Make For Adsense) Sites And Arbitragers?
Print screens below shows sample of a MFA.
 
These websites basically have no content. Their pages are full with Adsense begging pathetically to be clicked. Their existence is only for one reason – to make money from Google Adsense, usually by taking advantage of visitors that click on your website.
How MFA (Make For Adsense) Sites And Arbitragers Suck My Income?
MFA sites bids the minimum amount on a keyword and with the relevant keyword of your content, these MFA ads be will showed in your Adsense text ads.
Your readers clicks on these MFA text ads, you make few cents (probably 1 to 3 cents or so). Your readers are then brought to the MFA sites, filled with real Adsense Text ads. Your readers click and MFA make $1 or more. Not all will click on the ads on MFA, but it’s definitely enough for them to break-even and make 50% to 500% return.
This whole process is called the PPC Arbitrage. PPC Arbitrage not only affects your Adsense income but also the experience of using your site. Readers expect something informative, but their click leads them to more confusing ads.
