MFA

What does "MFA" mean?

It means "made for adsense".

In other words there are sites out there that have adsense ads on them but hardly any content.

I have seen sites like this that have adsense ads on them but then they have just a line or two of content. Some MFA sites that I have seen have lines of links to other site but they still don't have much content.

Apparently Adsense is working hard to cancel the accounts (or sites) that have these kinds of layouts. Although a lot of people are still posting that they still see a lot of these sites around.

Adsense Referrals - Are They Worth It?

The jury seems to be "out" on this issue.

When asked the question of whether or not putting the adsense referral ads on one's site would increase their adsense earnings even more, the replies were not all that favorable. There was even some grumbling about how placing referral ads on one's site would benefit everyone BUT the website publisher!

A few people have said that when they first put the referral ads on their site(s) they did get more income from them but that didn't last for more than the first month that the ads were put on the site.

Personally I have just started to add the adsense referral ads to some of my sites and its just too early to tell of any results yet.

My best piece of advice would be for you to experiment with the adsense refferal ads. Make sure you pick ads that are related to the content of your site.

What Does CPM Mean?

From Adsense's own site:

"From a publisher's perspective, the effective cost-per-thousand impressions (eCPM) is a useful way to compare revenue across different channels and advertising programs. It is calculated by dividing total earnings by the number of impressions in thousands. For example, if a publisher earned $180 from 45,000 impressions, the eCPM would equal $180/45, or $4.00. However, please keep in mind that eCPM is a reporting feature that does not represent the actual amount paid to a publisher."

Personally I use it as a way to judge what kind of rate I'm getting from advertisers - in other words - are my sites drawing high-paying advertisers
