new adwords changes and their effect on adsense

this could mark the end of adsense arbitrage for spammy, worthless sites

[elsewhen]

adwords advertisers will now have their landing pages factored into the "quality score" - this means that advertisers with worthless MFA landing pages will not have their ads displayed as often or at all:

[adwords.google.com...]

i think this is a wonderful step! spammy adsense arbitrage has probably seen its last days, AND: it could mean the end of cheap and worthless ads on publisher's pages.

will be interesting to see how much poor landing pages will factor into the quality score.

EPC has increased

Same here. EPC increased by 27% compared to November 2005 average.

But there are still new MFA sites.
I just discovered yesterday some sort of technical dictionary as I added some sites to the URL filter

The only content for each word is

one sentence

728x90

Links about the word

200x90 Adlink unit

My earnings are down but the ads displayed haven't changed. Seasonal variation or is it these new changes?
