1.8 URL structure & internationalisationMediumInferred
Trailing-slash inconsistency
If /page and /page/ both resolve to 200, I have two URLs for one page. I pick one form and redirect the other so the site speaks with one voice.
What it is
/page and /page/ both resolve.
Why it matters
Duplicate URLs split signals.
How to fix it
Pick one form; redirect the other; canonicalise.
How to find it on your site
- Test a sample of URLs with and without the trailing slash.
- Check whether both return 200 instead of one redirecting.
- Choose a single convention, with or without the slash, and enforce it.
- Redirect the non-preferred form and make canonicals match.
Cross-reference to ranking and citation factors
Trailing-slash duplicates split signals across identical pages. Consistency consolidates them onto one URL.
Impact
Low-medium. Inferred.
