I havent notice a drop on my sites..... i love yahoo my sites rank well in yahoo but not on google...
yahoo are acting very weird, today they've recached my website and that particular cached version from today shows my website as it was 5 days ago before I made a few changes, while yesterday's cached page was up to date...
yes my website moved from top 3 to third page when i noticed it now after reading this ! hope it comes back.
In my business area, there is a tremendous amount of spam in both yahoo and msn. these guys need to get serious about cleaning up the garbage.
If it wasn't for Yahoo, my main site would get almost no search engine traffic. 1st and 2nd page for many competitive keywords, too bad they can't hold a candle to Google in terms of number of searches, if so I could probably retire...
