Search Engine Saturation tool
I found an interesting Search Engine tool which allows you to find out which pages of your Website are indexed by the major Search Engines. Most webmasters would use the “site:www.yourdomain.com” (or equivalent) search function to do this but this tool allows you to do this kind of search on 7 Search Engines at once: Google, MSN Search, Yahoo, AllTheWeb, HotBot, Altavista and Lycos. It's called a Search Engine Saturation tool.
ppcse.net is also a PPC SE [no kiddin’!] and provides more free webmaster tools, including meta tag generator, linkpop checker, Whois lookup and stat counter.
