Frequently Asked Questions

A canonical tag (<link rel="canonical" href="URL">) tells search engines which version of a page is the preferred one. It helps prevent duplicate content issues by consolidating ranking signals to a single URL.

Incorrect canonical tags can cause search engines to index the wrong page, split link equity, or ignore your preferred URL. Regular checks ensure your SEO strategy is properly executed.

A self-referencing canonical is when a page's canonical URL points to itself (the same URL). This is widely recommended by Google to reinforce the page as the original source, even if there are no duplicates.

Our Canonical Tag Checker fetches the HTML of each submitted URL via a secure proxy, then scans for <link rel="canonical"> tags. It compares the canonical URL against the page URL and reports any mismatches, missing tags, or multiple tags.

Yes. Enter up to 20 URLs (one per line) in the input area. The tool processes them simultaneously and displays results in a table for easy comparison.

The tool will show an error status and explain the issue (e.g., network error, page not found). Ensure the URL is publicly accessible and not blocked by robots.txt or a firewall.

A canonical tag is a hint to search engines about the preferred URL, while the original page remains accessible to users. A 301 redirect permanently forwards both users and search engines to a new URL. Use canonicals for duplicate content; use 301s for moved pages.
