Eric Enge

General Manager, Perficient Digital

Publishes the studies that end the arguments.

Eric Enge is General Manager at Perficient Digital and one of the three co-authors of The Art of SEO. His distinguishing habit is publishing primary research with sample sizes large enough to actually mean something — a rare posture in a discipline that produces enormous quantities of confident opinion.

Research as a practice

Enge's studies — on voice-assistant accuracy, featured snippet behaviour, mobile ranking differences, link-signal decay and more — are among the few SEO sources that use proper sample sizes and state their methodology in the open. The findings are not always what practitioners want to hear, which is a point in their favour.

Enterprise consulting

At Perficient he works on large-scale digital transformation programmes where organic search is one of many workstreams. That environment keeps the research anchored to commercial reality rather than the debate cycle.
