GEO experiments, plated before persuasion

GEO Test Bench

Saskia Vermeer turns GEO tactics into repeatable experiment designs, with control prompts, sampling rules, variance checks, and commercial readouts that teams can defend after the first promising answer disappears.

Prepared by Saskia Vermeer for teams that would rather test an answer-engine claim than repeat it.

02 / test design

A useful GEO test has more than a before-and-after screenshot.

A

Control answer path

Keep the query, market, model, and source surface stable enough to know what did not move.

B

Treatment answer path

Change one content, entity, citation, or prompt condition without smuggling in extra advantages.

R

Repeat serving

Run enough cycles to catch stochastic praise, timing effects, and answer wording that only looked durable once.

featured readout

This is where the GEO recommendation meets the holdout.

Every issue separates the method from the marketing claim: what changed, what stayed fixed, how many answer runs were sampled, where the model drifted, and whether the result is strong enough to influence content, source, or budget decisions.

Publish the weak signal. Name the confounder. Repeat before rollout. Translate lift into action.
