Canonical Tag Generator
iWebSeoTool Canonical Tag Generator: Paste a URL and get a ready-to-use canonical tag in one click, with no sign-up and nothing stored. Generate one tag or a batch, copy the exact code, and paste it into your page head.
Paste the tag inside the <head> section of that page's HTML (or into your CMS SEO settings), one canonical tag per page. This tool only builds the tag — it does not check the page, look for an existing canonical, or add the tag to any website for you. Everything runs in your browser — nothing is stored.
How to use this tool
This canonical link generator is built for a single, focused job:
- Paste the full preferred URL for a page, or several URLs, one per line, for a batch.
- Generate the tag or tags.
- Copy the exact code.
- Paste it inside the page’s head section, with one canonical tag per page.
Writing a good canonical URL
To create a canonical tag that search engines can trust, keep these points in mind:
- Use an absolute URL starting with https://, including the full domain.
- Point to the version you actually want indexed, not a test, staging or parameter version.
- Match the site’s trailing-slash version consistently, so the canonical does not disagree with the site’s own links.
- Use the same preferred version across internal links, sitemaps and the canonical tag itself.
Honest limits
This rel canonical tag maker builds the tag only. It does not check that the page loads, does not look for an existing canonical tag on the page, and does not add the tag to any site, so those checks and the final placement are yours. If a page already has a canonical tag, remove the old one before adding a new one, because two different tags on one page send conflicting signals. Remember too that a canonical tag is a hint, not a command: search engines usually follow it, but they can choose a different version if they see stronger signals elsewhere. This canonical URL code tool is therefore a time-saver for writing correct code, not a guarantee about how a page will be indexed, even if you generate canonical tags online for a whole batch at once.

Frequently asked questions
No. It generates the tag only. It does not look for an existing canonical tag, check that the page loads, or add the tag to your site. Use the generated code as a starting point, then check the page yourself and add it through your site’s editor, theme or plugin.
No. A canonical tag is only a hint to search engines about the preferred version, and the other versions can still be visited. A 301 redirect actually sends visitors and search engines to a different URL, so the old address is no longer served.
Absolute. A canonical URL should start with https:// and include the full domain, so there is no doubt about which page it refers to. A relative URL can be misread, especially when a page is reached through different paths.
Search engines may ignore both, or pick one in a way you did not intend, because the signals conflict. Keep exactly one canonical tag per page, and check that plugins, themes and manual edits are not each adding a different one.
A canonical tag is a small piece of code in a page’s head that names the preferred version of that page. It helps when similar or duplicate pages exist, for example with tracking parameters or different URLs showing the same content, by telling search engines which version should be treated as the main one.
A self-referencing canonical tag is one that points to the page it sits on. It is common practice because it confirms which version of that page is the preferred one, even when the page has no duplicates, and it helps search engines ignore parameter or tracking versions of the same URL.
Paste it inside the head section of the page’s HTML, so it appears before the closing head tag. There should be only one canonical tag on the page, and it should name the full preferred URL for that page.
