Why use this tool

Review canonical relationships, compare host and path signals, and generate the link tag snippet you need to publish.

Use this when auditing canonical relationships or preparing metadata for a page template.

It highlights whether the canonical points to the same page, another page, or another domain.

01Enter the page URL and intended canonical URL.

02Review the verdict and the generated canonical tag.

03Copy the canonical snippet only after the chosen URL matches your preferred indexable page.

Confirm the input is the format you intended.

Scan the result before using it in a document, URL, config, or message.

Copy only the output you need.

Does this fetch a live page?

No. It checks the URLs you enter and generates the tag snippet locally.

What is a self-canonical?

A self-canonical is when a page declares itself as its own canonical, signaling that it is the preferred version of that URL.

When would a cross-domain canonical be used?

When content appears on multiple domains and you want search engines to consolidate authority on one preferred version.

Generate and validate hreflang link tags and XML sitemap entries. CSV bulk import, x-default ready, return-tag checks built in.

Run page launch checks for title, description, canonical, robots, sitemap, and hreflang in one workspace.

Break any URL into protocol, host, path, query, and hash — UTM-labeled, double-encoding flagged, JSON output.
