A plain-language explanation
An internet search engine is a system that finds, organizes and presents resources corresponding to the user’s query.
Where it helps in practice
A search engine discovers, organises and presents resources for a query, while results are an interpretation rather than a complete web catalogue.
The decision before implementation
Build technically accessible, understandable and useful pages and separate user needs from chasing one algorithm.
How to verify the result
Review indexation, visibility, clicks, visit quality and differences across engines and markets.
