These are the Best SEO Blogs on the planet. I used several subjective and objective factors to prune and rank this list. You can read about them here. If you are interested, I also compiled a list of the Top SEO Trade Publications, the Top 42 SEO Bloggers, and the Most Popular SEO Blogs.
Quick Note: If this list looks weird without the likes of Searchenginejournal.com, Searchenginewatch.com, Searchengineland.com, SEOChat.com, Clickz.com, Searchengineguide.com, or Emarketer.com, it’s because I’ve given those guys the enviable classification of SEO Trade Publications. They are ad-driven expo-promoting mega-blogs. They are awesome, but they’re also a little different than blogs.
How I Built This List:
1. I looked at all the other Top SEO Blog lists on the web, including Invesp’s, SEOMoz’s, TopRank’s, and Alltop’s. I also added several mentioned in other blogs. Then I merged everything into a big spreadsheet. I started out with about 140 blogs and trade publications.
2. Then, I started trimming. I visited every single site and looked to see if it was still alive, and whether or not it was really about SEO. It turns out, a lot of them *used* to have something to do with SEO like 8 years ago, but were inactive or off subject now. A good deal more were really more about social media, PPC, or general internet marketing. Most of those were eliminated. I plan to build another list at some point, but this is a list of blogs that are pure SEO blogs.
3. I also removed 7 sites that I consider to be trade publications. These are blogs. They are not necessarily published by a single blogger, but they have characteristics that differentiated them from trade pubs.
How I Ranked This List:
1. I started with the average rank from the other lists referenced above.
2. I revisited each site, this time taking the time to read 2 or 3 articles in their entirety. I gave each blog a subjective content rating based on my assessment of how deep it dug into a subject. I have a strong preference for a numbers-driven, scientific approach. I also preferred original content (read: stuff I didn’t know). Based on this subjective rating, I bumped blogs up or down from their original position; sometimes as many as 20 slots.
3. I pulled Compete.com and Quantcast.com numbers for each of the blog’s domains. High traffic sites moved up in ranks, low traffic sites moved down; sometimes by as many as 10 slots.
That’s it. That’s how I got here. These are, in my opinion the Best SEO Blogs anywhere.
