Does this fetch or crawl the URL?
No. It only checks the format of the text you typed — it doesn't verify the live page.

Check a Canonical URL's Format
Review a URL for HTTPS, trailing slash, and tracking parameters before using it as a canonical link, right in your browser.
What this checks — and what it doesn't
Type a URL and this tool runs three checks directly on that text: whether it starts with https://, whether it ends with a trailing slash, and whether it contains a query string (flagged as something to review for tracking parameters). It reports the canonical value back to you alongside the results.
This is a format check on the string you typed, not a live crawl of your actual page — it doesn't fetch the URL, confirm the page exists, or verify what canonical tag is actually rendered in that page's HTML. For that, you'd check the live page's source or use Search Console.
Workflow at a glance
Use this quick flow to understand where the tool fits in your work and what to review before relying on the output.
Review checklist
Before
Decide your site's consistent format for trailing slashes before checking individual URLs.
After
View-source or inspect the actual live page to confirm its rendered canonical tag matches what you checked here.
When to run this check
Use it before setting a canonical tag to catch obvious formatting issues — a missing HTTPS, an inconsistent trailing slash, or leftover tracking parameters — that can create duplicate-URL confusion for search engines.

Trailing slash check
Reports whether the URL ends with a trailing slash, useful for spotting inconsistency.
Query parameter flag
Warns when a URL contains a query string that might be a tracking parameter worth removing.
Instant, text-based check
Results update as soon as you enter a URL — no page fetch involved.

Checking whether trailing slashes and protocols are consistent across a site's pages.
Where your URL goes
The check runs directly in your browser on the text you type — the URL is never fetched or sent to a server.
Choosing a clean canonical URL
- Pick one consistent format (with or without a trailing slash) and use it across your whole site's canonical tags.
- Strip tracking parameters like utm_source from a canonical URL rather than including them.
- Always use HTTPS in a canonical tag if your site serves pages over HTTPS.
- After cleaning up the URL here, confirm the live page's actual canonical tag matches what you intended.
Canonical URL mistakes to avoid
Assuming this checks the live page
This reviews the format of the text you typed — it doesn't fetch or verify what's actually rendered on your page.
Mixing trailing-slash styles across a site
Inconsistent formatting between pages can create unnecessary duplicate-URL signals.
Leaving tracking parameters in a canonical URL
Query strings like utm_source should usually be removed from the canonical value.
Forgetting to check the actual page source
Use browser dev tools or view-source to confirm the canonical tag rendered on the live page matches what you planned.
What to check on the live page too
Canonical URL Checker catches format issues before they reach your page's metadata. Pair it with an actual check of the live page's rendered canonical tag to be fully confident it's correct.
