FREQUENTLY ASKED QUESTIONS
Everything you need to know about canonical URL monitoring
What is a canonical URL?
A canonical URL is an HTML tag that tells search engines which version of a page is the preferred one. When the same content is accessible at multiple URLs, the canonical tag prevents duplicate content penalties by pointing search engines to the authoritative version.
Why do canonical URLs sometimes point to the wrong domain?
This commonly happens when code is deployed from a staging or development environment without updating the canonical tags. If your canonical URL points to staging.example.com instead of www.example.com, search engines may index the wrong version or penalize your site for duplicate content.
What does SecurityBot check for?
SecurityBot checks every page for: canonical tag presence, domain matching, multiple canonical tags, HTTPS usage, og:url consistency, and trailing slash mismatches. Each issue is scored and accompanied by specific recommendations.
What is og:url and why does it matter?
The og:url meta tag defines the canonical URL for social media platforms like Facebook and LinkedIn. If it points to a different domain than your canonical tag, shared links may resolve incorrectly and your social traffic could be lost.
How often are canonical URLs checked?
SecurityBot checks your canonical URLs daily across all cached pages. You'll see a per-page breakdown showing exactly which pages have issues so you can fix them quickly.
