I feel so wield that, my sites get the No.1 in Google, but very low in Yahoo! And when I type the key phrase to find my site in Yahoo, it is the very old version; but if type mydomain.com to search my site, it is the newest version.
I think the old version(haven't been optimized) pull down my position on Yahoo, then what should I do? I will appreciate you for your any help!
