Nice little article on how to let search engines better understand who you are... and by you, I mean your website.

I remember when I first started to learn html all you needed was your meta tag and bam Google knew you.

Now this stuff speaks alot closer to the semantic nerd in me and I like it alot. Hopefully can come in handy in the future.

The tool looks like the most helpful thing so bookmark this website:
