This might be subjective but I feel Web Marketing Guru is the best SEO company. We have worked with a few agencies over the past 5 years, WMG is much different in some aspects, especially in their client servicing aspect, which ensures client satisfaction.

Their work is great but there are a few other things that make things so much better, like their approachable team, quick response, and asking the right questions. Happy to have found them and work with them for our brand.
