When it comes to AdSense, it’s sometimes easier to follow some rules than others. I have been using AdSense for about a year now and I still don’t understand what the true definition of MFA or Made for AdSense means.
Does it mean?
1. AdSense arbitrage?
2. Site with only AdSense ads?
3. Site with the maximum amount of AdSense ads?
4. Site with only AdSense ads above the fold?
From my understanding, AdSense arbitrage and sites with only AdSense are MFA sites.
My Understanding
MFA is purchasing traffic through AdWords at a low cost, and then targeting keywords on your site that generate a great pay per click rate. Thus, when users click ads you end up getting more money back then what you paid for the traffic.
I do think it’s true that sites that are plastered with Adsense ads and have little or hard to find content are more likely to be considered MFA sites.
I don’t believe that Google has any problem with arbitrage (purchasing Adwords ads at a cost lower than what you expect to earn from the clicks on your Adsense ads), as long as you have quality content on your site. And you have to follow the Adwords landing page quality guidelines too, of course.
