I have been doing SEO for over 6 years.
Algorithms have changed drastically since the dawn of SEO.
I have kept up with the trends and will NEVER be defeated by Google. All of my SEO tactics are Penguin, Panda, and Hummingbird-safe.
I plain get results. Over and over. Period!
With search engine optimization, most huge agencies have NO IDEA how to do it effectively, nor efficiently. You would have no idea because they pride themselves on a professional presentation and take money from business owners.
SEO is second nature to me. I do it...
