My site got hit big time this weekend! My earnings on Saturday and Sunday got cut by about %70. Although I am not found by my 300 or so unique keyphrases per day by Google anymore, (yup, I must be penalized, not banned though) it is still worth it to keep adsense on my site. CTR is just a tad below average, and cpm is just a little bit down. Nevertheless, any little bit counts, even if its just $250 for the month. Yahoo and MSN work well together to help keep my site somewhat profitable in the meantime.
