Hi man. I used to be just about as lost about SEO as you, but I got over that.
Basically, SEO is just about getting your webpage(or website) ranking for a certain keyword or keywords on search engine.so the first step is of course picking a keyword you want to rank, and hopefully not too hard to do so. if you really want more detailed seo info might as well just head to the freebie sectionsand grab some of those seo reports, like the Google domination method, rankmover by daniel(explains how onpage and offpage seo gets along),aand seo recipe.
