Duplicated Page Titles

Duplicated Page Title Sets | Canonical Pages

In this guide we describe what this page title is, what the check is, how it works, and we provide context as to why this SEO check is performed. The duplicated page title check is performed exclusively on canonical pages (pages with a self-referential canonical tag) within this part of reporting.


Duplicated Page Title Sets

Where multiple canonical pages share the same page title they are defined as a duplicated page title set. Canonical pages are by definition the canonical version of the content, the content should be unique. Consequently, the page titles should be unique and reflect the content on the page.


What is a Page Title?

A page title is a tag containing text that exists in the source code of a page and is only visible or used in Search Engine Result Pages (SERPs). Page titles are one of the most powerful on-page direct ranking factors in SEO. The page should contain the page’s target keywords to drive relevance between the page and the keywords you want it to rank for.

The page title can directly influence the organic visibility of each page for the keywords you want to get traffic for. As such this SEO component should be made a priority where issues are detected.

The page title including the HTML tags (of our homepage) sits in the <head> section of the source code and looks like this:

<title>Web Crawler | SEO Tools | Raptor - Digital Marketing Tools</title>


What is a Canonical Page?

A canonical page is a webpage that has a self-referential canonical tag present on it. A canonical tag advises Google as to the preferred / original version of content. If a page / piece of content is accessible from multiple URLs or is duplicated across multiple pages, a canonical tag helps to define the ‘canonical’ version.

A canonical tag contains a URL and if that URL matches the URL of the page being accessed, it is defined as a canonical page. Canonical pages are typically the ‘SEO’ pages of a site as they are most likely to appear in the search results. The canonical tag of our homepage looks like this in HTML:

<link rel="canonical" href="">


What Are Duplicated Page Title Sets?

Where two canonical pages have identical page titles, they form a ‘duplicate page title set. Canonical pages should, for the most part, have unique page titles that contain target keywords and encourage clicks. Duplicate page titles often imply poorly optimised pages and are a quick win in terms of improving the SEO of the site.

Duplicate page title sets may contain more than just two pages, a single page title could be duplicated across any number of pages. This component of a webpage is often overlooked and so it is possible to have a single page title used on every page of a site.

What Do We Check & How?

Our SEO auditing tool crawls every page and extracts the page title if / where present, and later during the analysis phase, compares them all to find duplicate page title sets. Where we identify pages that share exactly matching page title text, we flag these and mark them as being a ‘duplicate page title set’.

We present the data for this in the reporting tabs and SEO audit charts. The raw data is also available to download from the export tab in reporting, where you can get both CSV and XLXS files for any project or site.

As mentioned previously, these checks are performed exclusively on canonical pages, so if a page title is duplicated across multiple non-canonical pages this would not be flagged as an error here. You will be able to see all duplicate page title sets under the ‘page title’ category in the SEO Errors report.


What Should You Do with This Data?

You can use our software to identify duplicate page titles across your site and you can use that data to:

  • Re-write the affected page titles
  • Improve the organic visibility of the affected pages
  • Provide the list of duplicate page title sets to a client
  • Count errors on a site
