AI Search Answers Change: What Session Evidence Should a GEO Review Retain?

Teams often debate screenshots: “the brand appeared last week; why not today?” Without the exact question, time, entry point, login state, page version, and visible sources, one image cannot show whether a change came from a model, interface, query reformulation, or content update.

Full screen recordings are expensive, but a review without an evidence trail costs more.

The SearchLog study, released June 3, 2026, presents a browser extension that can capture queries, result ranking, available AI summaries, clicks, scrolling, tabs, and a time sequence, storing sessions as event streams and HTML snapshots. It is a laboratory research tool; it does not mean businesses should collect individual users' browsing data.

Define the minimum session record first

For internal testing, retain the question, language and region, platform and entry point, timestamp, login or personalisation state, full AI answer, visible sources, brand facts in the answer, version of official pages opened, and human-verification result. Record interaction detail only when there is a clear purpose, permission, and data minimisation.

Make logs serve repair, not user surveillance

Align answer changes with official-site releases, price updates, model announcements, and competitor changes. If the issue is a missing citation, inspect sources and pages; if it is a factual error, use content and compliance correction. Do not declare an optimisation successful or unsuccessful from one session. User behaviour logs must follow privacy, employment, and relevant platform rules.

GEO Radar at https://www.georadar.top can retain cross-platform answers and reports for fixed questions, reducing manual comparison effort. It does not replace privacy assessment or collect end-user browsing logs.
