I’ve been using Website Grader for a year or so now for checking how my website’s SEO is coming along, and whilst I don’t hold much belief in the ‘scoring’ mechanic, it’s useful to see how a site performs against the individual criteria (links, domain age, image attributes etc etc).

I recently came across WooRank which does a similar job but checks some additional criteria. Run both tools (for free) on a website to see how well it has been SEO’d (although both ignore recency, frequency, keyword selection and other factors which are critical to organic search success.
