About this website metadata checker

Our free metadata checker fetches any URL using a server-side request (just like Googlebot does) and extracts every meta tag in one clean, scannable report. Drop a URL, the metadata checker returns the title tag with character and pixel length, meta description with character count, canonical link with target URL resolution, robots directives, every Open Graph tag (og:title, og:description, og:image, og:type, og:url), every Twitter card tag (twitter:card, twitter:title, twitter:image, twitter:creator) and any JSON-LD structured data blocks present on the page.

The metadata checker also flags common SEO issues: missing canonical, duplicate H1, title tag too long, meta description out of range, missing OG image, missing Twitter card. Use it as a competitor metadata checker (paste any URL, competitor or your own), a pre-launch audit tool (verify metadata before pushing to production), or a debugging tool (figure out why a page isn't showing the right preview on social platforms).

No signup, no quotas, no rate limits, just paste a URL and get the full metadata report. Built for SEO operators, content marketers, technical SEO consultants and developers who would otherwise be clicking through view-source on every page.

Frequently asked questions

What metadata does this check?

It checks standard HTML tags (Title, Description, Canonical, Robots), Open Graph tags (Facebook/LinkedIn), and Twitter Cards.

How does the AI provide suggestions?

We feed the raw extracted tags to our AI model, which acts as an SEO expert to suggest specific improvements combining length, relevance, and best practices.

Why do social previews matter?

When users share your link, the preview image and description directly impact the Click-Through Rate from social platforms back to your site.

What is website metadata?

Website metadata is the information in a page's head that describes it: the title tag, meta description, canonical URL, robots rules and social tags like Open Graph. Search engines and social platforms read it to build your result and link preview.

Is this website metadata checker free?

Yes. This website metadata checker is free with no signup. Paste any public URL to check its website metadata in seconds.

Which platforms can I preview?

Google, X, LinkedIn, Facebook and Slack. Switch between them to see exactly how your link will look when someone shares it.

What is the metadata score?

Every tag we check counts. A tag that passes counts fully, a warning counts half and a missing tag counts zero. 80 or more is a good score.

What size should my og:image be?

1200 × 630 pixels works well on most platforms. Keep important text away from the edges because some platforms crop the image.

Why does my new image not show when I share the link?

Social platforms cache previews. After updating your tags, use the platform's own debugger tool, such as LinkedIn Post Inspector, to refresh it.

Do I need both Open Graph and Twitter tags?

Open Graph covers most platforms, and X falls back to Open Graph when Twitter tags are missing. Add twitter:card so X shows a large image preview.

Can I check competitor pages?

Yes. Any public URL works, so you can see how competitors write their titles, descriptions and social previews.

What is Open Graph?

Open Graph is a set of meta tags (og:title, og:description, og:image) that control how a link looks when shared on Facebook, LinkedIn, Slack and other apps. Without them, platforms guess and the preview often looks broken.

How do I write a good meta description?

Summarise what the page offers in about 150 characters, include the main keyword naturally, and end with a reason to click. Each page should have its own description; Google may rewrite it if it doesn't match the search.
