Google Trends: weblogtoolscollection.com provides (slightly) interesting facts on your blog. Though the product is free, signing in is required to see the number estimates. Not all sites seem to have a lot of data in Google Trends but it was fun to browse the various links. Most interesting to me were the “also visited” section and the “also searched” section. Matt Cutts had an interesting writeup on Google Trends for websites a little over a week ago.
