For those of us who are not SEO gurus, we need to test things out first before applying it to a clients site. We also sound out other SEO guys for ideas and suggestion on how to proceed with a project.

The SEO labs section of Webmaster Serve was created so that you can ask "silly SEO questions" try out this that could be daft or could get your to page 1 .
Feel free to experiment in the labs.
