Verifying that a canonical tag is recognized and honored by search engines involves using various tools and strategies, including Google Search Console, analyzing server responses, and employing crawlers like Screaming Frog. By ensuring proper implementation and monitoring, webmasters can confirm that search engines are respecting their preferred URLs.

Google Search Console

URL Inspection Tool

The URL Inspection tool in Google Search Console allows webmasters to check the URL's status in the Google index. This tool shows how Googlebot sees the page, including whether the canonical tag is recognized. To use it:

  1. Go to HTTPStatus.io.
  2. Enter the URL and click "Check Status."
  3. Review the results under the "Headers" section for the canonical tag.
