I found a nice utility that is somewhat like a Swiss Army Knife for checking search engine ranking and several other things for your store. The free version (we all know how free has appeal here) isn't a timed demo or crippleware, just lacks the bells and whistles of their retail versions. They don't require any forms to be filled out, etc. Just an email address and password when you register it.
