The practical guide
What this check is really for
Canonical tags answer an ownership question: which URL should represent this content? The checker makes the relationship visible before a theme change creates a larger indexing problem.
Confirm intent
A different canonical may be correct, but it should be deliberate.
Compare the graph
Check sitemap entries and internal links against the chosen canonical.
Inspect rendered HTML
Use browser tools or page source to confirm what the theme actually emits.
Worked example
A useful result starts with a specific situation.
A variant URL canonicalizes to a product URL, but a collection page canonicalizes to the same product by mistake.
Requested URL and declared canonical URL.
A URL relationship review with a path mismatch warning.
This compares pasted URLs and cannot inspect live HTML.
Before you act
Avoid the shortcuts that create a worse page.
Use this when a URL ownership question is blocking a product or collection SEO decision.
Common failure modes
- Using canonical tags to hide duplicate content without checking intent.
- Putting a non-indexable or broken URL in the canonical.
- Ignoring internal links that point to a different version.

How this tool works
A useful answer first. A product conversation second.
Pulse's free tools are deliberately narrow. They do not pretend to replace a live crawl, a provider's answer, or an experienced Shopify operator.
They help you identify the next question worth asking. If you want the recurring workflow—tracked questions, store context, reviewable fixes, and measurement—that is where Pulse fits.
Does this inspect the live HTML?
No. It compares the URLs you paste. Confirm the actual rendered link tag in the page source or browser tools.
Should every page self-canonicalize?
Often, but the right canonical depends on the page's role, variants, duplicates, and what should be indexed.
