What is an SEO expert?
The best way to describe this person or business is someone that is submerged in the world of online marketing, advertising and SEO. They spend their time learning and staying up to date on changes in the industry.
They have groups they are apart of and mastermind with other like-minded professionals. Keeping up to date on these subjects takes a certain kind of person. One that has your businesses success as their top priority as it is also their own success.
When one succeeds so will the other (generally speaking).
