I love rankings, what can I say. After I published the “Top 20 Blogs About Blogging” list I thought that someone would replicate it for the SEO sphere. But no one did, so here we go again.

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 20 Blogs About Blogging" list ranks blogs according to their Google Pagerank, Alexa rank, number of Bloglines subscribers and Technorati authority.

Each of the four factors range from 0 to 10, where 10 is the best score. The maximum total score for each blog, therefore, is 40. There will be monthly updates. Below the table you will find the details about the algorithm (check also the Top 20 SEO Blogs).

Here are the  Top 20 Blogs. We have already created the Top 20 Blogs About Blogging and the Top 20 SEO Blogs. Now it is time to cover the web design niche.

I have a lot of fun compiling these lists because it allows me to discover a bunch of new blogs, most of them with excellent content. It is also interesting to see how the different blogs on a specific niche perform under the parameters. Once again we based the analysis on Google’s Pagerank, Alexa rank, Bloglines subscribers and Technorati authority. The details about the algorithm can be found below the table.
