About Keystone Search

We're a boutique SEO agency based in Denver, working remotely with growing businesses across North America and Europe. Small by design — the people you hire are the people who do the work.

Why "Keystone"

A keystone is the single stone that holds an arch together; remove it and everything else falls. That's how we treat organic search — as the load-bearing piece of a marketing system, not a side project. We were tired of watching good companies pour money into tactics that looked busy but moved nothing, so we built an agency around a simpler promise: do the few things that carry weight, and prove they worked.

Who runs it

Keystone Search was founded by Sophia Renner, who spent nine years leading SEO and content teams in-house at SaaS and retail companies before going independent. She started the agency after one too many "growth strategies" that ignored the unglamorous fundamentals. Around her is a compact team of technical specialists, writers and an outreach lead — everyone senior, no junior staff billed at senior rates.

How we work

Three principles keep us honest:

We take on a limited number of clients so each one gets real attention. When we're full, we say so rather than stretch thin.
