Know the source.Eric Enge is a search-marketing veteran best known as a co-author of The Art of SEO and for running some of the most-cited empirical studies in the industry.

Who he is

Eric Enge is a digital-marketing leader who built his reputation on doing the homework. He founded Stone Temple Consulting, a Boston-area agency that became known less for hot takes than for large-scale, methodical SEO research — studies on featured snippets, mobile-first indexing, voice search accuracy, and link signals that the wider industry cited for years. Stone Temple was acquired by Perficient in 2018, where Enge went on to lead its digital-marketing practice.

Why he matters

In a field crowded with opinion, Enge’s contribution has been evidence. His team repeatedly tested claims most marketers simply repeated, publishing data that either confirmed or quietly demolished conventional wisdom. That same temperament runs through The Art of SEO, the O’Reilly reference he co-authors with Stephan Spencer and Jessie Stricchiola — a book that qualifies and sources its claims rather than asserting them.

Where you’ll see his work

Beyond the book, Enge is a long-running conference speaker and created the “Here’s Why” short-form video series explaining search and marketing concepts. His studies remain a useful antidote to tactic-of-the-month thinking: when someone insists a ranking factor works a certain way, the first question a careful SEO asks is whether anyone has actually tested it the way Enge would.

How to use this

If you are building an SEO program, treat Enge’s body of work as a model for the discipline you want internally — hypothesis, test, measure, publish. The specific findings age as Google changes, but the method does not. Pair his research mindset with RGM’s technical SEO and SEO library.
