Where to start?

Find a method for your task

Choose your question. Each path connects existing methods, useful sources and an outcome you can document. Stop at the step that answers your need.

View all 24 paths

Work through the data before drawing conclusions

Match entities without merging namesakes

Before merging records, check object type, identifier system, dates and contradictions. Distinguish duplicates, namesakes, establishments and related organisations.

Record observations

Use the local tool

In-depth practical guides

Methods for reading, searching, monitoring, migrating and testing a multilingual corpus with evidence and inspection criteria.

Worked exercises available : 51

Read and verify sources

Start from a claim and find the document, version and status. The expected output is a verifiable reference retaining the qualifications that limit the conclusion.

Prepare and compare data

Check keys, schema and units before matching tables. Local tools help detect duplicates, changes between versions and differences in scope.

Publish and maintain a site

Connect each check to a URL and a real journey: HTTP response, languages, redirects, rendering and recovery. Keep defect evidence and correction checks.

Organise measurement and monitoring

Define what is counted, when and under which conditions. Retain failures, denominators and calculation rules when interpreting a change.

Test agents and their actions

Test the boundary between retrieved evidence, a generated proposal and a genuinely authorized action.

Choose a source family

Topic pages to select a service and understand what its result can establish.

03 / METHODS

Which protocol should you use?

Start with the decision at hand. Each method produces a different form of evidence; the protocols can then be combined.

These protocols complement the catalogue’s practical guides. Use the filter to choose a starting point; several methods can work together.

04 / READING PATHS

Choose a reading path

Four short paths start from the problem to solve: visibility, evidence, decisions or data reuse.

01 / VISIBILITY

Be found, understood and cited

SEO, SXO and GEO → editorial architecture → AI visibility measurement.

Follow this path02 / EVIDENCE

Build verifiable authority

Evidence doctrine → AI citations → source architecture.

Follow this path03 / DECISION

Choose a proportionate intervention

Measurement → intervention scenarios → strategic audit.

Follow this path04 / DATA

Reuse a public dataset with care

Listing and licence → file and method → version and limitations → traceable claim.

DEEPER READING / PRACTICE

Transition from reading to a re-use method

A guide becomes useful when it allows you to conduct a check and explain the result. The reading should therefore focus on the information to be kept as well as on the succession of the steps.

Updated on .

Priority checks

Identify the necessary entries, the expected output and the limits of the method. Try the protocol on a simple case before applying it to a large corpus.

Interpretation pitfalls

Following the steps without understanding their purpose can give a facade conformity. An unexpected outcome deserves an investigation, even if all the cases of the procedure are scratched.

Working record to retain

A application sheet preserves the chosen case, the steps carried out, the differences encountered and the authorized conclusion. It makes it easier to compare two executions of the same guide.
