Meta Tag Checker

Inspect important page-head tags without sending your code to a server. The tool reports what is present and avoids treating every missing optional tag as an error.

“Not found” is an observation, not always an error. For example, a robots meta tag is optional when the default index/follow behaviour is intended.

Result quality guidance

Developer handoff

Check a page-head example before it is added to a template.

Static HTML review

Inspect generated source without sharing private draft code.

Metadata cleanup

Compare the tags that exist with the purpose of the page.

What it checks

Use the result as evidence, not a score.

Title, description, canonical, and robots elements
Open Graph title, description, and image
Twitter Card declaration
The exact values found in pasted HTML

What it cannot check

The live URL or server response headers

Indexing, ranking, or platform cache state

How it works

Input, inspect, improve, verify.

The tool processes what you enter, shows a plain-language result, and gives you a safer next step. Make the change on your website, deploy it, then test the live page again.

Popular use cases

Useful before and after publishing.

Developer handoff

Check a page-head example before it is added to a template.

Static HTML review

Inspect generated source without sharing private draft code.

Metadata cleanup

Compare the tags that exist with the purpose of the page.

Pro tips

Small checks that prevent avoidable mistakes.

Paste the final generated HTML when possible, not only a component template.
A missing robots meta tag normally means the default behaviour applies; it is not automatically broken.
Keep canonical URLs absolute and deliberate.
Use the live Link Preview after deployment to test fetched social metadata.

Common issues and solutions

What to review when the result looks wrong.

A tag is not detected

Check spelling, quotes, and whether the element is inside the pasted text.

The source and browser differ

A client script may be changing tags. Inspect both the server HTML and hydrated DOM.

Several canonical tags exist

This simple tool reports the first. Remove conflicting declarations and verify the final page source.

Frequently asked questions

Short answers before you make a change.

Is pasted HTML uploaded?

No. This checker parses the text locally in your browser.

Are all missing tags errors?

No. Some tags are optional or depend on intent. The result is evidence for review, not an automatic SEO score.

Can it check a live URL?

This version checks pasted HTML. Use the One Website Checkup or Social Link Preview for a public live URL.
