Survival of the Fittest - Blocking URLs for highest eCPM

Share your strategies for choosing URLs to add to the Competitive Ad Filter

I recently started to realize the potential power of using Adsense's Competitive Ad Filter efficiently to raise eCPM. Now I know nothing is concrete about techniques that are guaranteed to work but surely blocking URLs that have no chance of reporting conversion data back to Google can only be a good thing.

The technique I am currently using is:
- Blocking MFAs.
- Blocking sites with no obvious conversion goal. These includes sites like information sites who's only point of contact is email/telephone/fax, sites who don't sell a product directly or have no automated process to allow the user to purchase online, sites that offer no sign up features like newsletters.
- Blocking really ugly and unnavigable sites.
- Blocking sites whose ad copy is so far from the theme of my site that users most likely won't click in the first place.

I have just started implementing this strategy over the last 3 days so I am prepared to wait the safe 3-4 week period to see if smart pricing kicks in from sites that I have allowed through. The essence of my strategy is to only show sites that have a good chance of reporting conversion data back to Google. There has been a slight drop in my CTR as a result of blocking MFAs but this was expected.

I'd be interested to hear others chip in.
