result of the adsense competitive filter

After about 20 days since the first adsense competitive filter experiment. I have the following conclusion:

Competitive Ads filter is useless

Unlike the many hypes people hear, The Competitive Ads Filter seems to be useless to me. Since the introduction of the competitive ads filter experiment on 10 August 2008, my earning stay in a usual range i.e. there is no increase in the earning.

In short, you may want to use competitive ads filter if your earning per click is around 1 cent a click. If you have more than 5 cents a click, it seems like the ads filter does not have much effect anyway.
