A great metric tool for a webmaster or site owner is knowing how popular and important their pages are to search engines. A great tool for figuring this out is the Site Explorer utility available from Yahoo!. What Site Explorer does is give you a listing of all indexed pages within a site, in order of importance. You can use this to see what subjects you should cover on a more regular basis, and also can use it to spark some creativity. For example, if you know that two really old pages are highly popular, you may want to highlight them in a new post, or in a dedicated “Hot Stories” section on your site. This helps new readers find your popular content without having to go through a search engine.
