History of Websites

Today I had a need to look at the history of a website.  There are many different ways to look up how a page looked before it was last updated.  Looking at the Cached image in a Goolge search is one way.  Simply type in the sites URL into the Google search box and then select the Cached image.  Google will display when the site was updated and will allow you to go to a current page.  This only works if you want to go back 1 update.  Another and more inclusive way to see a pages history is to use webarchive simply paste in the website URL and you will be brought to a screen with all available updates.  This is only usefull on sites that are activily crawled however.  Finding out who owns a site is also helpful, the whois records a domain owners information.  I also like to conduct a related search or a linked to search this shows others who are connected to that site.  Type in link: websiteinfo.com into the search bar or a related search.  Related: http.www.website.com

Do you have other tips or tricks that you use?
