Experiment Results

Read out one SEO split test: which group won, by how much, whether the difference is significant, what else happened during the test, and what to do next. Experiments are created in the GSC Wizard app (its Experimentation page, where the control and variant URL groups are defined), not through the MCP; the tools here read and score them. The user's request may contain a property, an experiment name or id, a test window, a confidence level, or a note on what was changed on the variant pages.

Steps

1. Resolve the property. If the user's request or the conversation names a property, use it. Site URLs use GSC formats: sc-domain:example.com or https://www.example.com/. Otherwise call list_sites and pick the obvious match. If several plausible properties exist, ask the user which one before continuing.

2. Find the experiment. Call list_experiments with the siteUrl; add includeArchived: true when the user asks about a finished or old test.

   • Each entry carries id, name, description, status, startDate, groupCount and groups (group, urlCount, color); the first group is the control.
   • Pick the experiment the user named, or show the list in a short table and ask when more than one is active.
   • An empty list comes with emptyBecause and nextStep. When error is set the list could not be read, and the empty result does not mean the property has none.
   • When none exists, tell the user to create one in the app first (define the control and variant URL groups there) and stop.
