About metatagpreviewer
metatagpreviewer is a free set of SEO meta tag tools designed to help developers, content creators, and SEO practitioners understand and improve how their pages appear in search results and on social platforms.
Why we built this
Most meta tag tools we found either required an account before showing any results, interrupted the workflow with paywalls, or buried the preview behind slow-loading dashboards. We wanted something that works immediately — paste page HTML or type your tags and see the result in seconds, with no signup, no login, and no ads blocking the output.
The preview tool lets you type a title and description and instantly see how they would appear in a Google snippet, a Facebook link card, and an X/Twitter card. The URL checker analyzes pasted page HTML in your browser and runs a complete tag analysis. The generator produces clean, copy-paste-ready HTML. The character counter shows exactly where Google will truncate your text.
How the scoring works
The SEO score on the URL checker starts at 100 and deducts points for missing or problematic tags. Errors (missing title, missing description, titles over 60 characters) deduct 15 points each. Warnings (missing OG tags, missing Twitter Card, no canonical) deduct 8 points each. Informational issues (missing og:type, no robots meta) deduct 3 points each. The score gives a rough signal — a score of 85 is solid; below 60 means there are meaningful gaps to address.
The scoring is conservative by design. We only flag things that genuinely matter for search and social performance, not exhaustive checklists of rarely-used tags.
Privacy
When you use the URL checker, the HTML you paste is analyzed locally in your browser. We do not store, log, or share the source you paste. Nothing is written to a database or sent to a server for analysis.
We do not require an account, and we do not collect any personal data to use the tools. See the privacy policy for full details.
