Every page has a different title.

Why: Search engines use titles to tell pages apart. When two pages share a title, they compete for the same searches, and one may be left out of results. Case is ignored.

Pages with noindex, or with a canonical link to another URL, are left out, because search engines do not show them as themselves.

When off: duplicate titles pass.
