Found this bot spidering my site today. Seems to be obeying robots.txt. Google search claims they analyze your website and will optimize your site for a fee. This one was new to me so I thought I would pass it along to the forum members. Here is one item from the log:
91.194.225.nnn - - [27/Nov/2010:14:44:03 -0500] "GET / HTTP/1.1" 200 29525 "-" "Mozilla/5.0 (compatible; Lipperhey Link Explorer; [

I did not ask them to analyze my site. They did not contact me to say they had, nor ask me to use their service.
