If you're not using Yahoo! Site Explorer to determine how your site is indexed at that search engine, then you should be. If you have a Yahoo Store, now you've got even more motivation to get it done. Last night, Yahoo introduced the ability to authenticate Yahoo! Stores in Site Explorer.

From the official post:

Registering and authenticating your site with Yahoo! Site Explorer allows you to access detailed information in Yahoo! Search for your site's online presence. You can get information such as:

    * Find which sub-pages within a URL are indexed by Yahoo!.
    * Find pages that link to that site or any page. (inlinks)
    * Submit and track feeds for your sites.

In order to register and authenticate your site you will need to add your site to Site Explorer, copy your authentication key information, then add your authentication information to your store. Once completed, you can then submit a request to authenticate your site with Site Explorer.
