Yahoo has updated Site Explorer, its tool for webmasters that shares what Yahoo knows about your site in terms of indexed pages and links. The latest version allows users to authenticate via meta tags, in case uploading a file to the site's home directory is not possible or desired; and detailed authentication errors are provided when things go wrong. In addition, new Site Explorer badges are available for showing the world how many people link to your site (as far as Yahoo knows).
One tool, which Andy Beal calls "a disaster waiting to happen," allows users to remove their site from Yahoo's index.
"If this loop hole is not fixed it's only a matter of time before webmasters start waking up to entire sites missing from the Yahoo index. Yahoo accounts are too accessible to phishing and hack attempts to be the only barrier for such a powerful tool," writes Beal.
