Google Trends for Websites is a relatively new – free – offering from Google which allows you to track the clickthroughs from Google to any site on the web. This means you can compare how you’re doing against your competitors, which is always fun. Unfortunately, you have to get a certain amount of clickthroughs to register on the graphs, which might not make it very useful for lower-traffic sites, such as many industrial companies. However, a really good, in-depth introduction to Google Trends for Websites appeared on the Occam’s Razor blog recently, and it gives you a good flavour of what this tool can do. Have a read.
