Stonetemple.com announced that they will be doing two things soon:
1. Providing a free site review for some lucky winner
2. Sharing the results of the changes made (SERPs/traffic improvements) after 3-4 months.
This is great for both reasons. Some lucky webmaster gets a professional site review, and we SEOs get to look behind the scenes to see what changes that professional recommended. We all like peeking through other SEO's curtains, don't we?
To find out how you can get your site reviewed, or just want to participate in the "peeking", check out their blog post.
