At the end it all comes down to one thing – Targeted Traffic! But how you get there can be quite different and in my personal experience proper Search Engine Optimization is one of the simplest ways to get your own UNFAIR SHARE of the visitors.

Luckily, guys at SEOMoz have compiled a Search Engine Ranking Factors Cheat sheet that combines the answers from quite a few industry recognized SEO experts and presented it in a simple to understand and follow format. Bookmark and print it!
