What is a trailing slash?
A trailing slash is the slash at the end of a URL path, such as /services/. Sites may choose slash or non-slash URLs, but consistency matters.
Why check trailing slashes?
If both versions resolve as separate pages, they can create duplicate URL versions. Check redirects and canonical tags when changing a site's slash convention.
SEO best practice
Choose one URL format for your site and use it consistently in internal links, canonical URLs and XML sitemaps.
