This list was made using pretty much the same algorithm (only small modifications were made, mainly due to the fact that SEO blogs are more popular). Once again the list should be useful because it is based on objective factors. There are many “Top SEO Blogs” lists around the web, but most of them are based on the preferences of the author.
The Top 25 SEO Blogs list, instead, ranks the blogs according to their Google Pagerank, Alexa rank, number of Bloglines subscribers and Technorati authority. Each factor has a score from 0 to 10, and the maximum score for each blog is 40. Details about the algorithm can be found below the table.
