Testimonials
"We saw an immediate, significant improvement based on the work we did with Define Media. We didn't expect that big or quick an impact, but the results were impressive." Julie HansenCRO & US CEO, Babbel
We have worked with Marshall and his team on several projects, primarily focused on due diligence of prospective investments. Their work is thorough and on point and they have been able to provide quick turn-arounds in the face of tight deadlines. The DMG team has proved their ability to get up-to-speed on projects quickly and execute with a thoughtful, insightful report. They are the first group that I call on for SEO/SEM-related diligence work. Chris Cavanagh - General Partner at Guidepost Growth Equity
Marshall and the Define team are the best in the business. I’ve worked with them for five years, and they always provide creative, intelligent, actionable advice. I recommend them highly. Paul Greenberg - CEO, Butter Works
When launching our new site at BostonGlobe.com, we had a unique challenge to make sure that our new site was visible and optimized for search engines to find and index. Marshall and the Define Media team have always been our go-to experts for complex projects such as this as well as ongoing help training and educating our producers and journalists about the best practices to make our quality content as visible to search engine users as possible. Jeff Moriarty Chief Product Officer, Nexstar Media Group
