HubSpot is a really useful site that generates a free SEO report on any site. The analysis is very good and the data returned and the comments are very useful. Definitely one to bookmark.
I took The liberty of checking our resident domains and here's the result:
cadtutor.net (David) = 95/100
freedigitalphotos.net (James) = 94/100
gardenvisit.com (Tom) = 85/100
All very high scores (as you might expect) but I'm the winner!
