A plain-language explanation
SERP, i.e. Search Engine Results Page, is a page of results displayed by the search engine after entering a query.
Where it helps in practice
A SERP includes links, maps, products, answers and AI elements and varies by query and user context.
The decision before implementation
Analyse feature types and intent rather than one blue-link position and record country, device and date.
How to verify the result
Measure visibility share, clicks and conversions for query groups while accounting for layout changes.
