Yahoo! has added more detailed information to the Site Explorer, which is an amazing tool to check the number of pages of the site indexed as well as to view inbound links to the site.
It was launched last November into BOSS, the Key Terms enable the developers to develop refinement terms for search services. You will not get information on Key Terms that are used on websites through the Site Explorer.
You can now see the information about the site's page being submitted to a social bookmarking site in Yahoo! Site Explorer.
In case you have provided a feed with the SearchMonkey template or have marked up the site with SearchMonkey code, you will be able to see what Yahoo! has indexed by using Site Explorer.
Other than these additions, Yahoo! Has also updated the dashboard for Site Explorer and backend logic for SearchMonkey feeds. This will help developers in validating small test feeds in a lesser time.
