Wow, another new tool site discovered today. This was mentioned at DigitalPoint, and it’s a great site to check the health of your website. WebsiteGrader does handy things like check backlinks and ratings, as well as check for proper 301 Moved Permanently handling with your www and non-www domain. I think this along with a validator would really get your pages dialed in for bots scanning the site. I’ll definitely be using this service!
