DataHub Tools Meta Tags Generator

SEO Meta Tags Generator

Local-first

Generate title, description, canonical, robots, viewport, and language meta tags for static pages.

How this tool actually works

The generator requires title, description, and an absolute HTTP/HTTPS canonical URL, validates a practical robots-directive subset and language-tag shape, then emits a head snippet plus a comment for the root html lang attribute.

  • Generate title and description markup
  • Add robots, canonical, and viewport tags
  • Suggest an html lang attribute

How to use it

  1. Enter title, description, canonical, robots, and lang as separate key=value lines.
  2. Use an absolute canonical URL and a valid language tag.
  3. Place meta and link elements in head, but apply the html lang value to the root html element.
  4. Validate the deployed page because search engines may choose different titles, snippets, or canonicals.

Quick example

Example input

title=Data quality guide
description=Practical checks for analytics data.
canonical=https://example.com/data-quality/
robots=index,follow
lang=en

Expected result

A head snippet plus a separate <html lang="en"> instruction.

Do not accept fallback title or canonical values for a real page. A canonical is a search-engine hint, not access control or a guaranteed selection.

Best use cases

  • Draft metadata for one static page.
  • Review canonical and robots values before deployment.
  • Prepare a language attribute for the document root.

References and scope

HTML defines document metadata and the html lang attribute. Google documents how canonical and robots hints are interpreted in search systems.

Known limitations

  • The input format is one key=value pair per line.
  • Syntax checks do not prove canonical ownership or full BCP 47 conformance.
  • Strong page content and search-intent matching cannot be generated by tags alone.

FAQ

Where does html lang belong?

On the root html element; the generated head snippet includes a comment rather than an invalid html tag.

Does canonical force Google to use that URL?

No. It is a strong hint considered with redirects, links, sitemaps, and page content.

Are input values validated?

Basic required fields, HTTP/HTTPS canonical syntax, language-tag shape, and common robots directives are checked.

Can tags replace SEO content?

No. They describe and control parts of a page but do not replace useful content or intent matching.
