Resources to learn SEO?

I don't see much about formal instruction on SEO. Maybe I'm not looking in the right places? I want to do some web advertising and want to make the most of it.

One of the best authority sites out there about search engine optimization and search engine marketing is http://searchenginewatch.com/. Poke around in there for a while and you'll get an education.

If you want to know it right from the horse mouth, then read this blog: www(.)mattcutts(.)com(/)blog(/)

I did look these suggested info sources over briefly, and I can't thank you enough. Excellent, excellent starting points for helping me get educated.

I started out my SEO career reading SEO Book by Aaron Wall. I would suggest you download the book and read it offline; that works better.
I owe my thanks to one of my seniors for recommending such a great book to me

Once again, a big thank you! I'm very interested in getting into content writing, and SEO seems to part and parcel of doing it effectively.
