Just out of curiosity, how can one say someones an expert in SEO. Is there a degree, or some sort of studies for it, or just do alot of research, read things here and there, and just know your stuff?
I suppose anyone can say they're an SEO expert --- the real test is probably what others (clients) have to say about what you have done for them. A metaphor for the qualified SEO could be an online librarian -- with the learned skills to categorize websites into their appropriate "shelves" amongst specific, and/or related topics.
