Document the measurement context
Record date ranges, time zones, search type, geography, device, channel filters, and known tracking changes. A clean join cannot correct a mismatch in the question being asked.
Establish a page identifier
A search report may contain absolute URLs while an analytics export contains paths. Normalize carefully, keep the original values, and review parameters, redirects, and canonical mappings.
Keep the scopes distinct
Search Console clicks and analytics sessions are not interchangeable. Differences can reflect attribution, consent, filtering, and channel mix. Do not present their ratio as a conversion rate.
Review the page itself
Use the joined evidence to decide where to investigate. Read the page, examine the offer, and check the next step. A difference between signals does not establish a cause.
Write a reviewable finding
State what was observed, which sources support it, what is uncertain, and what should be checked next. Keep business relevance and confidence visible when prioritizing work.
