Zeta Interactive is a multidisciplinary agency based in the US (New York) that focuses among others on search engine optimization (SEO), social media and branding. I have been friends online with its vice president Hugo Guzman who is responsible for search and social media.
The trust I have in Hugo Guzman is the main reason why I decided to add Zeta Interactive to my SEO company directory.
Hugo Guzman's writings in his blog have impressed me again and again and thus I was willing to check out where he works. We have also interacted on social media quite a few times by now and again I was astounded by the high level expertise Mr. Guzman was showing. He easily matches industry leading experts.
