Strange ... Before the summer my SERPs for about 20 keywords were best in MSN, second best in Google, and worst in Yahoo. I think that's fairly typical. Now, a few months later, Yahoo results have become my best by far, with Google second, and MSN last! I was not doing too well at all on Yahoo, and now they have many of my keywords quite high, well ahead of Google's rankings. I've been traveling in our RV for the past few months and have not put any fresh content on the website. But I have consistently been submitting to directories. Are others seeing the same switch — that is, MSN SERPs going from 1st to worst; Yahoo SERPs going from worst to 1st?
I think yahoo is on the right track, they have been doing plenty of Social community building efforts by brining in the previous owner of Flikr to manage their web 2.0 efforts. I dont think it'll be long before Yahoo provides comparable results across the board to google.
I've not seen any sort of similar results. However, I have seen increased referrals from Yahoo...still not beating the others...but better.
