What Is a Trailing Slash in URL?

A trailing slash in URL is the character ‘/’ that comes after a domain name.

For example:

  • the URL www.example.com/ – have a trailing slash,
  • the URL www.example.com – does not.

When looking at various websites, you may see that some of them end with a slash and some of them don’t. In the past, this slash meant that the page was categorized as a directory.

On the other hand, URLs without this special character indicated that the site was a file. Nowadays, this division is considered arbitrary and even Google doesn’t analyze websites this way.

The changes over the years were caused by the development of file structures.

Now, modern network systems aren’t limited to simple designs. Directory pages with folders and files marked by the trailing slash have been replaced with templates storing the file structure, and dynamic files are used to form a page.

These modifications still confuse many users who aren’t sure whether to use a slash at the end of their URL or not.

Should You Use a Trailing Slash?

Since you know what a URL trailing slash is, it’s time to discuss when it’s worth using it. John Mueller himself spoke on Twitter about this phenomenon. He referred to allegations frequently raised by webmasters that concerned misleading use of slashes.

Mueller stressed that servers automatically categorize slashes placed at the end of URLs.

According to his opinion, it doesn’t really matter whether you put slashes after host or domain names. On the other hand, a slash placed somewhere else is perceived completely differently and affects the whole URL.

Google doesn’t impose the use of slashes or deleting them but it expects webmasters and users to be consistent in their activities. The application of slashes at the end of URLs is the most standard solution.

Take a look at a tweet by John Mueller:

Based on it, we can come to a few conclusions:

  • It’s ok to have trailing slashes after the domain name
  • Trailing slash matters for most URLs
  • Trailing slashes on hostnames don’t actually matter
  • Trailing slashes on path/file matter
  • File names should not have a trailing slash at the end

How Does Trailing Slash Affect SEO?

Although trailing slashes are inconspicuous elements, they may have a significant impact on website positions in the search results.

What problems can a trailing slash cause?

  • duplicate content – if two pages with the same content are found on one website and the slash is the only element that makes them different, then, we’re dealing with internal duplicate content. In such a situation, Google finds it hard to determine the original source and everything gets pretty chaotic. In this case, it’s crucial to choose one URL that will be the primary version crawled and indexed by Google.
  • crawling efficiency problems – if there are too many pages on a website, and each of them has a unique URL with a trailing slash, it may result in decreased crawl efficiency. In other words, Googlebot will have to spend more time on your website and waste your crawl budget on analyzing the same content. This, in turn, can have a negative impact on your website’s SEO.

Be Consistent

According to John Mueller, consistency is the key to success when it comes to fixing problems caused by trailing slashes.

Consequently, you should use only one URL version and then focus on this specific version in all your activities. This means linking to it, redirecting to it, adding it to the sitemap, marking it as rel-canonical, and more.

Trailing Slash Has an Impact on Reporting

Interestingly, it turns out thata trailing slash has an impact on Google Search Console reporting.

Using GSC, you can configure either a domain or URL prefix property. If you forget about the trailing slash when determining your URL prefix property such as a folder or domain, Google will add it automatically.

How will it impact reporting?

The visits to the property without the trailing slash won’t be counted and included in the report.

Why?

Because the property with the trailing slash has a higher level.

The same issue occurs when talking about Google Analytics and categorizing content by folder if your main pages do not have a slash.

If URL versions with and without the trailing slash work properly, they can be reported in Google Analytics.

Trailing Slash & SEO – The Takeaway

Now you know what a trailing slash in a URL is. Properly configured trailing slashes shouldn’t cause any problems. However, it’s worth keeping in mind that they can affect reporting.

When using trailing slashes, each page is analyzed and counted as a separate URL. Therefore, to avoid internal duplicate content, you should use appropriate 301 redirects and get rid of 404 errors. Thanks to it, identical pages won’t fight for the same positions.
