Some SEO sites

So in my off/unemployed time I've been building up my SEO and online reputation skills - a friend recommended to me a few good sites, figured I'll post one here for future reference :)

http://www.woorank.com/ - Great site - for *free* it will scan your site's code and overall will tell you weak spots (alt texts are off, no meta tags or descriptors, etc.) - been using this to help speed up the site-optimization process :)

Obviously for a fee they'll dig into things like your individual pages, but still - a good site overall.

I'm working on a HTML/XML parser in excel that will allow me to dump the raw code in and pull out "problem" areas because while a site like woorank is helpful, often enough I need to compile documents detailing exactly what needs to be changed, and where. Anything to speed it up :)
