The question
When structured data will genuinely help engines and AI understand a page.
You are deciding whether to add or change structured data on a page.
Why it matters
Schema is added indiscriminately or ignored entirely; the question is where it actually helps.
How to decide
IfThe page has clear entities or qualifies for rich results
ThenYes - add the fitting schema and validate it.
IfOrganisation or Person identity is unclear to models
ThenYes - prioritise entity schema.
IfExisting schema is invalid or misdescribes the page
ThenYes - fix it; broken schema can hurt.
