Missing 301 Redirects for Trailing Slash / Non-Slash URLs: How to Solve It
This issue is when a URL is accessible both with and without a trailing slash (e.g., /page/ and /page) as two separate non-redirecting responses instead of one canonical version. It typically stems from server or routing configuration that doesn't normalize trailing slashes before serving content. Left unresolved, this creates duplicate content at the technical URL level, splitting any links, crawl budget, and ranking signals between the two variants of what is really one page.
Why this happens
This stems from server or application routing that doesn't normalize trailing slashes before serving content, so a request for /page and a request for /page/ both resolve successfully as two independent, non-redirecting responses instead of one canonical version choosing to redirect to the other. Some web server and framework defaults handle this automatically while others require an explicit rule, so the outcome often depends entirely on which stack the site happens to run on rather than any conscious decision by whoever built it. It's also easy to introduce inconsistently across a single site, some internal links using a trailing slash and others not, if there's no site-wide convention enforced anywhere.
What it costs you
Two independently accessible URLs serving identical content create duplicate content at a purely technical level, and search engines spend part of their crawl budget on the redundant version instead of content that needs discovering. Any inbound links using the non-canonical variant split ranking signal away from the version you'd prefer to rank, since Google has to choose which to treat as authoritative rather than being told directly. It's a small, mechanical fix with an outsized benefit, consolidating signal previously divided between two versions of the same page.
