What are MFA sites?

Sometimes you will come across the following line in the directory guidelines when wanting to submit your site to a web directory.

Submissions will be rejected if your website is Made for Google Adsense (MFA) content only…

So what are MFA sites? MFA or Made For Adsense is pages that get traffic with the only purpose of getting others to click on there ad’s. The pages contain little information about one subject and on the top, before any relevant information is displayed you have a lot of advertisements, that most users will probably click on before they reach the few words of real content there is on this page. Some MFA sites advertise their services on Google Adwords and get a click from a user who is interested in the subject, and then the user is taken to a page where the MFA site display their own ads that has a higher pay per click then what the owner of the site displayed his ad for in Google.

Making a MFA site can be profitable for a short period of time, before either Google finds out that the page is spam, or when someone reports the page to Google. I would not recommend creating MFA sites. The same goes for any page that contain mostly affiliate links or sponsor ads. While I certainly do not mind if a page contains ads on it, it should be kept in mind that there should be more content then ads on every page.
