This blog is for people with some understanding of SEO, but not for not for the real professionals.
Most people that I talk to, clients and potential clients, have some understanding of the search engines, but are not interested in all the gory technical details.
In my posts I try to explain technical aspects using terms and explanations that are as simple as possible to give a basic understanding, fully aware that I am frequently over-simplifying.
The technical details are widely available for those that are interested. I would highly recommend these sites if you wish to explore the technical aspects of search engine marketing:
Stuntdbl goes into lots of detail with very informative posts.
Search Engine Watch Forum You have to dig though the forum but lots of details.
Mil slita For the truly technical minded.
