Chris Boggs, who runs Web Traffic Advisors, has been doing the SEO and SEM thing since 2000 – for over 20 years. He has done SEO and PPC, and has even worked at both large and small agencies, as well as in-house at both large and small companies.
Boggs credits a lot of his success in the industry to what he learned from his service as a former US Marine. Not only that, he credits his previous jobs and bosses with his success. Barry Schwartz and Boggs spoke about this and chatted about some of the earlier days in SEM.
They even talked about some technical SEO topics and PPC topics, too.
