Fetch a URL, extract its canonical tag, and detect conflicts between the page and its canonical target.
We'll check for canonical tags, og:url, and robots directives.
Enter a URL above to analyze its canonical tag and detect potential SEO issues.
Incorrect canonicals can remove pages from Google. Fix conflicts before they impact indexing.
Find pages without canonical tags that could cause duplicate content issues.
Multiple canonical tags confuse search engines. We detect them instantly.
Compare canonical vs OG URL signals to spot conflicting directives.
Verify that pages properly self-reference or point to intended targets.
See if noindex or other directives conflict with your canonical strategy.
We fetch and analyze in real-time without storing your URLs.
Everything you need to know about canonical tags
Usually yes. If it points elsewhere, Google may index the canonical target instead of the current page. Self-referencing canonicals are the safest default.
Use https in the canonical and set up 301 redirects from http to https. This consolidates signals and avoids duplicate content issues.
Google may ignore all of them or pick one unpredictably. Always ensure only one canonical tag exists per page.
Ideally yes. Conflicting signals can confuse search engines about which URL to index and display.
No. We fetch the page HTML and analyze tags in real-time without storing any data.
It can, but it sends mixed signals. If a page is noindexed, the canonical is often ignored. Clean up these conflicts for clarity.
Canonical conflicts silently waste crawl budget. We audit entire sites and fix indexing issues so Google sees the right pages.
