From Chad Varela (Varela Dumpster Services):

"Looking for a SEO company can be confusing. If you don’t know much about it yourself then finding the right company that does SEO is kind of like guess work. Every company I spoke with let me feeling unsure if it was a good investment. Coalition Technologies gave me the confidence that my businesses visibility would increase. They are very knowledgeable and every time I have a question they are quick to answer it. The only company so far that I actually believed the results."
