What is the purpose in Wordpress blog comments that link google.com
 

I can't figure this one out...

I understand people leaving comments with their website address in the URL field, but I get some comments with just Google.com and less frequently Yahoo.com in the URL field of the comments, and can't figure out why they would want to leave that as the web address for their comments? What kind of benefit do they get from that if the blog approves the comment?

While I'm on it, can someone also explain what exactly is a "pingback" and how they are beneficial? Something I should approve?

They're testing to see if their links come through or they have misconfigured their blog spamming software.

Its google panda doing rogue posting.
It will get google ranked topspots in bing and whahoo.

please consult sally rand in this serious matter.
