How it scored

Every dimension is scored against this discipline’s published rubric. Open one to see the claim it was scored on, what the rubric measures there and how much it weighs, and where the evidence came from.

How we scored this

We read the agency’s public record first-hand — its site, pricing, case studies and independent reviews — and score what is checkable: what is published, not how it is phrased. There is no keyword counting or sentiment scoring. The label is a judgment on those facts, which is why each dimension shows the fact that decided it, the band it was judged against, and the sources — so you can check the call, and tell us if you think it is wrong. The full method, and who pays, is on how we vet.

Experimentation rigor (valid A/B testing)Excellent

Excellent — 5 of 5 on this rubric’s scale, from Poor (1) to Excellent (5). This dimension carries 25% of the total score.

Stronger here: CROHOUSE scores Excellent on the same dimension.

Verdict

Cro Metrics is a strong fit for established teams with enough traffic, internal resources, and budget to run a serious experimentation program. Reviews document testing rigor, research, UX, conversion and ROI improvements, and long-running client relationships. The tradeoff is significant cost—multiple reviewed engagements are $200K–$999K—and some build/QA speed depends on allocated staffing.
