Quick answer
Give standalone indexable pages titles that distinguish their subjects. Do not blindly change intentional duplicates such as canonicalised variants, redirects, search pages, filters, or non-indexable routes.
What the issue means
The same title text appearing on multiple URLs can be harmless or confusing depending on page purpose. A product family may share a template while individual pages still need distinct subjects. URL differences alone do not prove that titles must differ.
Why it matters for SEO
Unique titles make pages easier to identify and can clarify which result best matches a query. Duplicate text can also make audit triage harder. This finding does not prove that search engines will penalise the pages.
How NOTABIS detects it
The duplicate-title rule groups shared title values and distinguishes standalone indexable duplicates from canonical, redirect, search, filter, and non-indexable variants. Read the affected URL context and state before editing templates.
How to check it yourself
Export or crawl the affected URLs, record each title, canonical, robots directive, status, and page purpose, then group exact title values. Check whether the pages are genuinely competing documents.
How to fix it
Write titles around the unique subject, product, location, or task of each standalone page. Keep intentional variants’ canonical and indexability signals coherent. Recheck both the rendered title and the resulting duplicate group.
For instance, if colour variants have distinct, indexable landing pages, the title should identify the variant that a shopper will see:
<title>Blue Trail Running Shoes | Example Store</title>
<title>Black Trail Running Shoes | Example Store</title>
If those URLs are just filtered views of one product page and canonicalise to the same URL, separate titles may not be useful. Decide from the page purpose and indexing policy, not from the duplicate count alone.
When this is intentional or does not need fixing
Duplicates can be acceptable for redirects, private or noindex pages, parameter variants, and other URLs that are not intended to compete as standalone search results.

Review duplicate descriptions, canonical conflicts, and URL query variants together. Google’s title-link guidance explains that titles may be rewritten when another page element better describes the result.
