just like in many other fields, anyone can call themselves an SEO
there's probably only a few who actually know what they are doing
... compared to a great many who are selling an obsolete service.
you could search to see the number of results for SEO companies, but again the best wouldn't advertise themselves - leastways certainly not in a 'conventional' way
