I have found this blog to be not only filled with useful information on search engine optimization, digital PR and social media strategy, but it is also one of the more active marketing blogs on the web. Their recent blog post series titled the Top Ten SEO Tips for PR Professionals was very well done and filled with practical tips for establishing a strong SEO strategy.

In addition to the blog, I follow @leeodden on twitter for daily links to their company’s activities and smart tips for online marketing. Check it out.
