Please Help!

My Adsense cpc and monthly earning went down in 2006, and even more in the past two weeks.

Just today Iím reading about MFA and installed the preview tool in order to get rid of MFAs.

The question is how many URL (average) did you filter out to fix your problem?

The tool shows me only 12 URLs and the first 12 items I see are completely out of my site topic. So I suspect that may be a lot of URLs that I will need to stop.

Thank you in advance for any help.

Yes, there are sites that generate lists but you should consider that not all of the MFA's appear on every site and those lists can be very huge, therefore, they can fill your list (which have a 200 limit) with sites that would never appear on your site. I think it would be better for you to manually check for those crap sites and add them to your list.

Thanks Sonny and Chocorol!

Another question. If I copy and paste the first 12 URLs in my filter, how much time do I need to wait to see in the preview tool another set of 12 URLs?

It may take up to at least 48hrs for filtered ads to dissapear.

If 12 out of 12 ads are out-of-topic, then you have a long way to go to get a blacklist that works for you. Reason is that it takes 24-48 hours for blocked ads to disappear. Then you have to go all over again to see what other out-of-topic ads there might be. BUT WAIT! Before you now plunge into a frenzy of work and fill up your 200 slots in one evening, I strongly suggest to make A PLAN.

1) Identify the pages with the highest traffic
2) Identify for those pages where the majority of traffic is coming from (country-wise)
3) Check these page-country combinations FIRST with the preview tool

This way you get the necessary relevance for your blocking list - only pages that are "being seen", and only for those audiences that matter. You can leave the other pages/countries alone, because the impact on your bottom line will be tiny (if there is an impact at all).

It is a good idea to pull up the Alexa listings for advertisers you consider to block to see if the guys in question are still active. It's sort of eye-opening once you start doing this.

Also, check whether you have been site-targeted (in your earnings report). These ads appear to be out-of-topic because they are site targeted. This does not mean the advertisers are MFA. It just means that ads may be out-of-topic. If you see a big percentage of site-targeted ads, you can compare the eCPM values of contextual vs. site-targeted and then decide whether it makes sense to opt out of site-targeting. (But this is being covered in other threads here at WW.)
