Trailing slash or not — pick one and enforce it sitewide

Quick frame: Google treats /page and /page/ as different URLs by default. Pick one form, server-redirect the other, and emit self-referential canonicals. The choice doesn't matter — only that you pick.

The decision tree

Stack	Default	Recommendation
WordPress	trailing slash	keep
Next.js (App Router)	trailing slash	keep
Hugo	trailing slash	keep
Astro	no trailing slash	keep
Headless CMS + custom front-end	depends	pick based on convention

The pattern: pick whichever your framework defaults to. Fighting your framework on URL form costs maintenance for negligible benefit.

The three things you must do

1. Redirect the alternate form

Use the .htaccess generator or nginx generator to 301-redirect the non-canonical form. For example, if your canonical is with trailing slash:

RewriteCond %{REQUEST_URI} ^/.+[^/]$
RewriteCond %{REQUEST_URI} !\.[a-z]+$
RewriteRule ^(.*)$ /$1/ [R=301,L]

2. Self-referential canonical

Every page emits a canonical pointing to itself in the chosen form. The canonical tag generator toggle handles trailing-slash normalisation.

3. Normalise URLs across all surfaces

• Sitemap: only the canonical form.
• Internal links: only the canonical form.
• External campaigns: only the canonical form.

For bulk normalisation of an existing URL list, use the trailing slash converter.

The cost of not doing this

• Link equity splits across /page and /page/.
• Both variants appear in Search Console as separate URLs.
• Social engagement counters fragment.
• Backlinks pointing to one form don't reinforce the other.

Files with extensions

URLs ending in extensions (/file.pdf, /sitemap.xml) should never have trailing slashes. The trailing slash converter respects this.

FAQ

Q. Is one form genuinely better than the other for SEO? A. No. Google has confirmed neither form ranks better. Consistency matters; the choice doesn't.

Q. What about the homepage — slash or no slash? A. The homepage always has a single trailing slash (/). It's a special case; both forms (with and without slash) resolve to the same homepage.

Q. Will switching forms hurt rankings? A. Brief wobble (1–2 weeks) as Google re-indexes. Long-term, no impact if redirects are 301 and canonicals are consistent.
