Canonical Tag Generator
Canonical tags help search engines understand which version of a URL you want to appear in search results when you have duplicate or similar content on multiple URLs. This tool helps you generate proper canonical tags for your web pages.
How to use: Enter the URL you want to set as canonical, then click "Generate Tag". Copy the generated code and paste it into the <head> section of your HTML.
Include http:// or https:// and use the full, absolute URL
When to Use Canonical Tags
- Duplicate content: When you have identical or very similar content accessible on different URLs.
- Pagination: When you have content split across multiple pages (view-all pages should be canonical).
- Product variants: Product pages with different filters, sorting options, or URL parameters.
- HTTP/HTTPS versions: To indicate which protocol version is preferred (typically HTTPS).
- Mobile/desktop versions: If you maintain separate URLs for mobile and desktop versions.
Canonical Tag Best Practices
- Use absolute URLs: Always specify the complete URL including protocol (https://).
- Be consistent: Use the same case, protocol, and domain version (with/without www) across your site.
- Avoid canonicalization chains: Page A pointing to Page B, which points to Page C.
- Avoid conflicting signals: Ensure canonical tags match hreflang, sitemap entries, and 301 redirects.
- Self-referential canonical: Each page should have a canonical tag pointing to itself if it's the preferred version.
- Avoid multiple canonical tags: Each page should have only one canonical tag.
Canonical Tag Examples
<!-- Standard canonical tag -->
<link rel="canonical" href="https://example.com/product/" />
<!-- Self-referential canonical -->
<link rel="canonical" href="https://example.com/current-page/" />
<!-- Mobile to desktop canonical -->
<link rel="canonical" href="https://example.com/page/" />
<!-- Paginated series with view-all as canonical -->
<link rel="canonical" href="https://example.com/article?full=true" />

Note: Canonical tags are suggestions, not directives. Search engines may choose to ignore them if they detect conflicting signals or better alternatives.
