When you are researching keywords for a site, or reviewing them for an active SEO campaign, it is easy to get bogged down in the nitty gritty of the words. Over the years there have been loads of tools for analysing your text, telling you the keyword density (remember when that used to be important?).

The best tool out there is not a tool at all - at SnapShirts.com you can put in your website URL and it will give you a picture of a tag cloud like this:

But this isn't for just looking at - they will print this design on a T-Shirt for you. Great for your own personal website or blog. Have fun!
