Anyone know any good resources on the behaviour of google spiders? I notice various different types of visitors form Google in my log files For example here are 2 (real urls changed so for gawd sake dont start asking me about blue widgets ;-) ) 1) Google (216.239.45.4) [Label IP Address] Mountain View, California, United States, 0 returning visits Date Time Type WebPage 3rd February 2009 02:11:58 Page View No referring link bluewidgets.com/ 2) Google (74.125.75.19) [Label IP Address] Mountain View, California, United States, 0 returning visits Date Time Type WebPage 7th February 2009 16:08:35 Page View www.google.com/search?hl=en&q=site:www.bluewidgets.com orange-widgets www.bluewidgets.com/orange-widgets/ so as you can see the second request used the site command with a keyword after the url. Was this a human reviewer then?
