Aaron Wall noticed some major changes in the Yahoo! ranking algorithm. It is believed that these changes will have a major effect on sites which enjoy Yahoo! Rankings.
The major changes noticed by Aaron Wall are:
- botching part of a sitewide 301 redirect that they had followed for months – now both sites rank, but each ranks well for some portion of the queries
- a bit more weight on domain names
Some sites with high authority domains, like TheFreeDictionary.com, and all of its keyword heavy definition pages, enjoy a good ranking at Yahoo!
There are some other pages like, Yahoo! Directory, Yahoo! 360, Google Groups, Google Translate, Topix and About.com, where it can be seen that authority is more important than keywords in the URL.
It is a known fact that Yahoo! takes a close look at domain history and domain recognition, even for YSM things. Not very clearly why this is happening, but the short post from Mr.Wall is of high significance.
