How to fix duplicate title tags

Identical titles make separate pages look like the same page. Search engines pick one and suppress the rest, so your pricing, docs and blog pages compete with each other instead of ranking for their own terms.

What 13x checks

This is rule metadata.title-duplicates in the public registry: Titles are unique per page. It runs on every audit, against the pages we actually fetched, and its result is derived from the response rather than estimated.

Registry version 2026-07-30. Every rule is published, and the audit is deterministic — the same page produces the same finding every time.

The fix

The same text the audit hands you when this check fails on your own site.

Give each page its own title. Duplicates almost always mean the title is set once in a shared layout and never overridden per route.

Set a template in the layout and a short, specific title per page, so /pricing and /docs do not both render the site name alone.

Framework-specific versions

Where the change differs enough to be worth writing out separately.
