A trailing slash might seem harmless: www.example.com/path/ or www.example.com/path – what’s the difference? While the two versions may look identical, failing to set up proper redirects or canonical tags can lead to duplicate content issues. Search engines treat these URLs as separate pages, dividing rankings and link equity without you even realizing it. This issue often goes unnoticed, even during audits.
Duplicate content, diluted backlinks, and search engine confusion are just some of the consequences of poor trailing slash configurations. This can result in lower rankings, a loss of authority, and even navigation issues for users. Since most tools only check internal links, alternative URL versions often remain hidden – and so does the problem.
This trailing slash issue is deceptively tricky and often flies under the radar due to:
The Trailing Slash SEO Checker is built for developers and SEO professionals who want to tackle the often-overlooked trailing slash issue.

By addressing this technical detail, you can prevent ranking issues, improve website performance, and maintain a clean, optimized online presence.
No, the extension checks one page at a time. It does not scan the entire website automatically. While one page may have correct settings, this doesn’t guarantee that other pages are configured correctly.
The extension identifies the page you start on as the "original" page and then visits the alternative version (e.g., from /path/ to /path or vice versa). If the settings are correct, the alternative page will redirect back to the original page. However, if both pages remain accessible, there is an issue with the configuration.
If you’re unsure which version is canonical (original), use Google to visit the page. The version indexed by Google is typically the canonical one. Keep in mind, however, that Google may occasionally select the wrong version as canonical, so it’s important to confirm this with your developer.
If both the original and alternative pages are accessible, it indicates a configuration issue. This should be flagged immediately with your developer to ensure proper redirects or canonical settings are applied.
Visit your website starting from Google’s indexed version of the page. Activate the extension, which will load the alternative page. The extension will then determine:
- If the alternative page redirects back to the original page (correct configuration).
- If the alternative page remains accessible and shows its status code and canonical link element (indicating a potential issue).
The extension is a great starting point for spotting trailing slash issues but should be used as part of a broader SEO audit. It tests pages individually and provides insights, but a full website check requires additional tools or manual review.
If both the original and alternative versions of a page are accessible, there’s already a problem. Always ensure your website redirects one variant to the other using a 301 redirect or defines the canonical version explicitly.
