If you are interested in doing SEO for clients or for your own company, this is the place to start looking. I find that I constant go to his community for SEO knowledge and to stay current. Every SEO company I come across I look to see how much organic traffic going to their site to see if they actually know what they are doing. I just looked at develomark.com and it is over $130K a month in traffic! How would you like to not have to spend $130K a month in AdWords and get free traffic instead. It's a no-brainer!
