Yahoo has announced
that rolled out an index update on October 10, 2006. Marketers should
notice a change in some rankings and a shuffle of the pages in the
index.
Matt Cutts, the well known engineer at Google, has also announced
some updates going on at Google. Google just recently exported PageRank
info, so people should be seeing some changes in PR as viewed in the
Google toolbar. The rest of the changes at Google are infrastructure
changes and deal with the Supplemental results and making sure that
"site:" queries are more accurate. Google has also pushed out new
"link:" query information to reflect more backlinks pointing at sites.
There have also been recent upgrades to Yahoo's Site Explorer.
This program is a simpler and less enhanced version of Google's
Sitemaps program but is improving slowly. Check it out and watch for
future enhancements. It is also recommend that you convert your Google Sitemap to a Yahoo Sitemap and submit it to Yahoo for enhanced reporting in the Site Explorer program.
