A baseline needs an agreed purpose. Does management want to find incorrect service claims, understand available sources or track a region? That purpose determines the questions, systems and scope. Ten to fifteen questions per language can be a starting point; they are not a universally sufficient sample.
Context and scope
Four columns make the report readable: business question, tested system, finding and priority. Add the date, question-set version and raw evidence. Distinguish Google search results, AI Overviews, ChatGPT Search and Perplexity. A single percentage otherwise hides different observations.
A wrong city or outdated price is an important finding. It might come from conflicting pages, old directories or other sources. The error alone does not establish its cause. First check the attributed source and the current offer.
SOURCE/01 Full connects technical evidence, AI observations and a prioritised 90-day work list. The free short check covers one domain, three questions and three observations. These distinct scopes support an informed decision before a deeper analysis.
From a measurement to a management decision
Hypothetical report for a Swiss service business: three surfaces are reviewed separately. An inaccurate service claim gets high priority if it could lead customers to make an unsuitable enquiry. A missing mention is first repeated and investigated. The matrix below does not contain actual client results.
| Review point | Example / subject | Interpretation |
|---|---|---|
| ChatGPT Search | Outdated price stated; an old PDF visibly linked | Check the price source and assign an owner. |
| Google Search | Current service page indexed | Record as the technical foundation. |
| Perplexity | Owned page not cited in this run | Review repeated runs; do not assign a cause yet. |
| Management | Which change supports the buying decision? | Agree the correction, effort and review date. |
How to apply this
- State the business purpose in one sentence.
- Attach a source or saved test run to each finding.
- Assess impact, risk and effort separately.
- Plan repeat measurement with the same set and disclose changes to it.
