Start your review here http://www.seoconsultants.com/ which is the nearest you can get to peer reviewed SEO consultants directory.

Keep in mind that for every good SEO there are ten thousand crappy ones. Also the best SEOs in the world work for themselves because they make more money that way and those that choose to have clients do not come cheap!

1. Ask the candidate SEO company to provide a website in which it is ranked on the FIRST PAGE of Google and the search query contains:

a) No proper domain name in which an individual, company or other entity is included, nor any set of generic terms describing goods and services, or a major brand are contained within the domain name;
b) No specific reference to a specific name, entity or otherwise and its location, i.e., city, state, country. “Generic” descriptive text for goods and services are allowed, i.e., golf balls, attorney services, etc.;
c) Results exclusive of a directory listing or a set of links contained therein: only the domain named website appears by itself. For example, the result cannot be ABCtravel directory/domain name website;
d) Results in excess of 1 million;
e) No more than 6 words in the search query and the query is limited by conditions set forth in a) and b) above.

If the candidate SEO company cannot at least produce a single website through the above search scenario, then how do they expect to elevate your website ranking?

Good luck!

P.S. By the way, I know of a website that meets the above -described search criteria due to proper SEO; no Adsense, links, etc.

These are freelancers, who have huge amount of experience in the field of SEO, SEM….

This is my honest recommendation
