What meta tags should a page have?

Most pages should have a clear title tag, useful meta description, viewport tag, canonical URL where appropriate, and accurate social preview metadata.

The title tag is the page headline that browsers and search engines often use as the search result title.

What is a meta description?

A meta description summarizes the page and may influence the search snippet, although search engines can rewrite it.

What is a canonical tag?

A canonical tag signals the preferred URL for a page, which can help reduce duplicate-content confusion.

What does meta robots mean?

The meta robots tag can provide indexing and link-following directives such as index, noindex, follow, or nofollow.

What are Open Graph tags?

Open Graph tags control how links may appear on social platforms, including title, description, image, URL, and content type.

Why does my social preview look wrong?

The page may be missing social tags, the image may be unsuitable, or the social platform may be showing cached metadata.

Does this tool store checked URLs?

No account or storage is added by this page. URL checks may still require a network request, and pasted HTML is parsed locally.

Can I copy the meta tag analysis?

Yes. Use the copy summary button to copy the current metadata report.
