I love rankings, what can I say. After I published the “Top 25 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 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.

perfect blog.
Nobody writes comments for search engines, only proxies scrape comment to feed search engines.
thanks good blog.
ok iyi ama evet keske turkce de olsa…
Keke Trkeside olsa ama yinede guzel paylam..
Liked that list, though I’m biased in favor of SE Roundtable and SEOmoz.
hey
it’s very nice list !
Very nice list. Love reading and analyzing it. Though based on my subjective view, I would have chosen a different order. But your’s is objective, so perfectly fine.
IMHO, this is a bad list (I am not saying those blog is bad, but the way of judging those blog isn’t right.)
1- most seo experts consider alexa is out of the game.
it is better to use rss subscribers than this tool.
2- it is a top seo blog in English not worldwide, I think that there are many others language.
no wonder all the sites are in English.
keep an eye guys on Asia and Europe and be more specific.
Great list, nice to see old Matt Cutts not topping the charts – there’s a couple of great blogs I have never come across before.
Niceone, it’s very interesting scale of popularity….
Great list, hope to make it on there myself one day!
Bill, if you think it is suitable go ahead and create the Top 100 SEO blogs.
Whats really interesting, though, is that not all of those SEO blogs on the list have nofollow implemented on their comments.
Great list! Obviously there are a lot more than 25 SEO blogs, so perhaps I should create “top 100 list”?
I don’t really mind and I don’t think my blog is an actual SEO blog but I think I scored around 17 points with jimwestergren.com
Hope to see DoshDosh entering the list in near future.
Darren, what forums are you referring to?
Interesting list. You have forums on there, etc. LOL.
I wonder if pjmommy will ever make the list. I guess we’ll have to expand on our blogging content!
Hey Daniel,
I love this posts. I will also be happy to see other “top blogs” like “how to” blogs or business blogs
Great list of sites and a good reminder to update RSS subscriptions. Thanks!
Very nice list indeed!
Yeah I considered him, got 14 points or so.
Very nice list indeed!
Old lines, old habbits.
Right. Perhaps you should change the title though if you want to avoid confusion hehe.
I think there’s no A list blog that deals strictly with SEO anymore.
Yeah I am aware. It is very difficult to cut a clear line on what is an SEO blog and what is not, so I just considered blogs that have a “great” part of their content related to SEO (that is very flexible, I know :)).
As Alex reminded me in my own blog, and as Lee said about his own, SEOPedia is not “just” about SEO too.
23 .COMs! 1 .ORG! 1 .UK!
The remaining portion of the world does not have SEOS?
Nice Lee, thanks for sharing that. I will check how many of the 25 display feed count and consider using it as a factor.
He Daniel, thanks for including Online Marketing Blog! Along with Andy, we’re not exactly all about SEO, but that’s certainly a big part of our content.
Oh yeah, but I guess he can answer some questions via e-mail easily
I barely have enough time to keep up with these comments.
Alex, no worries, I always appreciate different points of views.
I also agree with you Daniel, and I want you to know I don’t want to be rude or anything like that.
Alex, it is quite difficult actually to use what you mentioned.
I would use MUCH more filters to decide top25. SERPs, RSS subscribers, traffic!
Andy and Sheila, thanks for stopping by. You did an outstanding job with the blog, it is no surprise you making it to the Top 10.
I’m married to the Marketing Pilgrim. We have fascinating conversations about blogging over dinner and wine. Is it healthy for our marriage for me to have blog envy over my husband’s blog?
Thanks for including Marketing Pilgrim on the list! We’re one of the youngest sites on the list – less than 2 years old – but glad to be in such great company.
Very nice list
Thanks for this list. I have been looking for a really good SEO blog for a while. A lot of blogs cover SEO but are not dedicated to it. Going to check these out!
Yeah in fact I thought about including the SERPs as a ranking factor :). Perhaps I will add it on the next update.
Wouldn’t it have been easier to just do a google (msn, yahoo) search on ‘seo’ or ‘seo blog’? Wouldn’t that tell you who the best seo is?
Yeah lately Pronet is focusing more on social media, but they have a lot of SEO content on the archives.
Great work Daniel. I thought Pronet Advertising was much about Social Networking as I found most articles on that. All interesting blogs and must read blogs.
