Duplicate titles

What this check looks for

This is a site-wide check: it groups every successfully-crawled page by its normalized title text (lower-cased, whitespace-collapsed) and fails every page in any group with two or more members. Pages with no title are skipped here since that's covered by the presence check. A site where every page's title is unique passes with no findings.

Why it matters

When two pages share a title, search engines have no textual signal to tell them apart and often end up picking one to show in results while suppressing (or poorly ranking) the other — this is a form of on-site keyword cannibalization. It also confuses AI answer engines that crawl multiple pages from your domain: if two different URLs present the same title, a model summarizing or citing your site can't reliably distinguish which page actually answers the user's question, and may cite the wrong one or skip both.

How to fix it

Give each page's title a distinguishing detail — usually the specific product, article, or category name — rather than reusing a generic template:

<!-- Page A -->
<title>Running Shoes | Acme Sportswear</title>

<!-- Page B (duplicate before fix) -->
<title>Running Shoes | Acme Sportswear</title>

<!-- Page B (after fix) -->
<title>Trail Running Shoes for Women | Acme Sportswear</title>

Audit any template-generated titles (category pages, paginated listings, filtered views) first — they're the most common source of duplication at scale.
