You know I really like the World of Search Engine Optimization. It is my main job and I am enjoy to do technological intelligence about SEO. Here are five seo blogs I appreciate to read every day :
Pandia Search Engine : a good blog with a lot of interesting news in SEO and Search Engines.
SEO by the SEA : blog of Bill Slawski, director of Search Marketing at KeyRelevance.
SEOmoz : a good website about SEO. Behind the blog there is a team and they propose often some web tools in SEO. Unfortunately, some of them are not free…
Bruceclay : a very good blog written by an Internet Business Consultant : Bruce Clay.
ComScore : it is not exactly a blog but a press center. It’s not the fifth blog I like the most. However, ComeScore represents a very useful source for Search Mesuring Information.
