Canonical Tag Generator

A canonical link tells a crawler which URL is the preferred copy when several addresses serve the same content. It is an HTML link element in the page head, not a redirect. This form only prints that element.

A canonical names the preferred address when several URLs serve the same content. It is not a redirect. Visitors can still open the duplicates. Crawlers are asked to treat the href as the main copy. Paste an absolute URL, including https. A tracking query you leave in the box becomes part of the href.

href is one of the values Canonical Tag Generator puts on screen. The preferred URL. The href is exactly the string you pasted, after the tag is formed. A parameter you did not want indexed will be in the href.

Read rel on its own before you mix it with the other rows. rel canonical marks the link as a preferred-URL hint. The attribute is written for you. It is not a meta robots tag and not a redirect.

Absolute URL answers a narrower question than the headline number. Crawlers need a full URL in this href. A path without a host is a weak href. Include https and the host.

Treat Duplicates as a label with a specific job. The tag belongs on the copies and on the preferred page. The generator prints one tag. You paste it in each head yourself.

The No fetch line is worth a full stop. The form does not request the URL. A dead URL still produces a tag. Check the URL in a browser before you publish the tag.

The tool does not lowercase the host, add a trailing slash, or check that the URL returns 200. What you paste is what the href contains. Put the same tag on the preferred URL and on each duplicate. An empty box does not invent an address.

If you remember one sequence from Canonical Tag Generator, remember the fields in the order they change a decision. href matters because The preferred URL. In practice, The href is exactly the string you pasted, after the tag is formed.

In practice, A dead URL still produces a tag. The mistake to avoid is this: Check the URL in a browser before you publish the tag. After that, the checks are simple. The URL is absolute and uses the host you want indexed. Tracking parameters were removed. The tag will be pasted on the duplicates and the preferred URL. You did not expect a redirect. You confirmed the URL loads.

The worked example for Canonical Tag Generator, read as one scene, is this. Paste https://example.com/seo-course?utm_source=newsletter. The tag’s href includes the utm query. If that parameter should not be the canonical, delete it and generate again. The page was not requested. Copy the cleaned tag into the head of /seo-course and into any duplicate such as /seo-course/. The tool did not add the trailing-slash variant for you.

Final notes for Canonical Tag Generator, written as decisions rather than as a table. When href is in front of you, decide using this: The preferred URL. A parameter you did not want indexed will be in the href. When rel is in front of you, decide using this: rel canonical marks the link as a preferred-URL hint. It is not a meta robots tag and not a redirect. When Absolute URL is in front of you, decide using this: Crawlers need a full URL in this href. Include https and the host. When Duplicates is in front of you, decide using this: The tag belongs on the copies and on the preferred page. You paste it in each head yourself. When No fetch is in front of you, decide using this: The form does not request the URL. Check the URL in a browser before you publish the tag. Then apply the checks without skipping one. The URL is absolute and uses the host you want indexed. Tracking parameters were removed. The tag will be pasted on the duplicates and the preferred URL. You did not expect a redirect. You confirmed the URL loads.

Keep Canonical Tag Generator as this step only. When the job moves on, the Meta Title & Description Generator is the next page: The Meta Title & Description Generator writes the HTML for a page title, a meta description, robots directives, and Open Graph and Twitter tags. The Meta Tag Analyzer covers a different piece of the same work: Meta Tag Analyzer asks for a page URL and then shows a title, description, and keyword line with character counts.
