Yahoo continues to add new data to its popular Site Explorer tool and, for reasons unknown, doesn’t tell anyone about it. Today, Barry Schwartz reported on Search Engine Roundtable about several new additions to Site Explorer’s data:

• Key Terms
• Delicious Activities
• Top Delicious Tags
• SearchMonkey Objects

Barry posted this screenshot showing the new features as they related to Search Engine Roundtable:

It was just a month ago that Yahoo expanded Site Explorer with a new “Top Queries/Top URLs” feature. Webmasters and search marketers still wonder, though, what Site Explorer’s fate will be if the Yahoo/Microsoft search deal gets approved. Yahoo hasn’t commented on our questions about that.

Postscript by Barry Schwartz: Yahoo has now announced it on the Yahoo Search Blog.
