12 Best Free Online Canonical Tag Checker Websites

Here is a list of the best free online canonical tag checker websites. A canonical tag is used to tell search engines that a specific URL is a copy of an original URL. If two or more pages have identical or similar content, it gets complicated to index. In fact, it negatively impacts SEO. In such a case, a canonical tag is added to the page. The canonical tag contains the URL of the master copy or original URL. After that, search engines identify the master cop as the original URL and the other page as the canonical URL. This prevents duplicate content issues and improves SEO.

A canonical tag checker is a tool that tests whether a web page has a canonical tag implemented or not. This is a simple tool where you have to enter the URL of the page that you want to check. If the page does have a canonical tag then it shows that along with the canonical URL. This post covers 12 websites that offer canonical tag checker tools. You can use any of these tools to check URLs for canonical tags.
