I just compiled this in answer to a PM and thought it might be useful to others as well. The question was about good resources for learning about SEO. I think Aaron Wall's SEOBook is a pretty good basic SEO primer. Aaron is somebody I respect but he has become a little bitter and rabidly anti-Google lately. Bear that in mind... Beyond that, SEO isn't static and to keep up with changes to algorithms and practices here are some blogs that I find interesting and useful: http://www.bruceclay.com/blog/ http://cre8pc.com/blog http://www.dailyblogtips.com/ http://google.blogspace.com/ http://googleblog.blogspot.com/ http://googlewebmastercentral.blogspot.com/ http://www.inspiredseo.com/feed/ http://www.mattcutts.com/blog http://www.free-seo-news.com/ (from Axandra - also comes as a newsletter) http://www.searchengineguide.com/searchbrief/ http://www.searchenginejournal.com/ http://www.seroundtable.com/ http://blog.searchenginewatch.com/blog/ http://www.seobook.com/ (Aaron Wall's blog) http://www.seomoz.org/blog http://www.ysearchblog.com/ As with anything SEO related, bear in mind that a lot of what you read should be considered speculation, although with most of the sources above I think it's fair to say it is informed speculation. My general advice is to read everything with a critical eye, look for evidence supporting or disconfirming what you read, and always remember that SEO tips that may have worked in 2004 may be ineffective or even detrimental today. What other sources do you regularly read and recommend to keep current with search engines and SEO?
