Through conducting over 350 scientific experiments on the Google algorithm over the past 4 years, our Co-Founder and Lead SEO, Kyle Roof was able to observe many things. One of his key findings was that there are correlational consistencies in particular ranking signals on top rankings pages. These findings essentially become our 'Recipe to Rank' and have formed the backbone of our SEO consulting methods and our well known SEO tool PageOptimizer Pro used by over 10,000 SEOs worldwide.
