Free Canonical & Robots Meta Tag Generator
Prevent duplicate-content issues and control how search engines index a page. Set your canonical URL and indexing preferences to generate the exact tags to paste into your <head>.
What is a canonical tag?
A canonical tag (rel="canonical") tells search engines which URL is the "master" version of a page when the same or very similar content is reachable at multiple URLs — for example with tracking parameters, print versions, or http/https and www variations. Google then consolidates ranking signals onto the canonical URL instead of splitting them.
The robots meta tag is the per-page control over indexing: noindex keeps a page out of search results, and nofollow tells crawlers not to follow its links.
Canonical and robots best practices
- Self-reference your canonical: most pages should point to themselves.
- Use absolute URLs and one consistent format (https + www or non-www, not both).
- Do not noindex AND canonicalize to the same target — pick one signal; mixed signals confuse Google.
- Never noindex a page you want to rank — it is the fastest way to disappear from search.
Frequently asked questions
When should I use a canonical tag?
Whenever the same content is accessible at more than one URL — parameter variations, pagination, syndicated content, or http/https/www duplicates. It consolidates ranking signals to your preferred URL.
What is the difference between noindex and canonical?
Canonical says "this other URL is the main version of this content." Noindex says "do not show this page in search at all." Use canonical for duplicates, noindex for pages you want fully excluded.
Can a canonical tag point to a different page?
It can, but only when the content is genuinely a duplicate or near-duplicate. Pointing a unique page’s canonical at an unrelated URL can deindex it.
Is this generator free?
