So I learned SEO myself, and now I'm using my decade of teaching experience to teach others.
You KNOW SEO matters, but you're either in one of two camps:
1. You've never even bothered trying SEO even though everybody keeps telling you that you "should."
2. You've tried to learn SEO, read tons of articles, read all the "secret hacks," and maybe even tried using a pricey SEO tool hoping it'd make sense (it didn't, did it?).
In both of those camps, you haven't had much of what really matters: RESULTS.
