Meta Preview Checker

Why preview metadata?

A title and meta description shape how a page may appear in search results and shared links. Previewing them helps catch truncation, vague copy, and missing context before publishing.

This tool shows approximations, not guarantees. Search engines may rewrite snippets, and social platforms may cache Open Graph data for a period of time.

What builds a search or social preview

Search engines and social platforms build a snippet, sometimes called an unfurl, from a handful of HTML meta tags: the page title element, the meta description, and Open Graph properties such as og:title, og:description, og:image, og:url, and og:site_name. X, formerly Twitter, reads a parallel set of twitter:card tags that most sites set to the same values as their Open Graph counterparts. This tool does not read any of those tags from a live page; there is no fetch or scrape step. It takes whatever title, description, URL, image address, and site name are typed into the fields here and renders three approximations: a Google-style search result, a generic Open Graph card of the kind Facebook, LinkedIn, and many chat apps render, and an X/Twitter-style card.

The length hints shown next to the title and description fields are simple character-count thresholds, not a guarantee: real truncation depends on rendered pixel width in a proportional font, so two titles of the same character count can wrap or truncate differently depending on which letters they use.

Neither Google nor a social platform is obligated to use submitted metadata as-is. Google can generate its own snippet from page content instead of the meta description when it judges the provided text unhelpful for a given search query, and social platforms typically cache Open Graph data after the first successful fetch, so editing a live page's tags does not retroactively update a preview already generated and cached elsewhere.

Worked example

The Fill sample button loads a 51-character title and a 109-character description:

• Title: ConvertUnlimited - Free Browser-Based Utility Tools, 51 characters
• Description: Convert, compress, preview, and generate useful web assets directly in your browser, with no signup required., 109 characters
• URL: https://convertunlimited.com/tools/
• Image: https://convertunlimited.com/og-image.png

Both counts land inside this tool's practical range, 30 to 60 for the title and 80 to 160 for the description, so neither hint fires. The description sits below the narrower 120 to 160 character target mentioned in the general length guidance on this page, which is a tighter, more conservative rule of thumb than the pass or fail thresholds the on-page hint actually checks against.

Limits and gotchas

• Nothing is fetched from the live page. The preview reflects only what is typed into the fields here; if the actual page's meta tags differ from these values, the live preview on Google or a social platform will differ from what this tool shows.
• Length hints are character counts, not pixel measurements. Real search result truncation depends on rendered width in a proportional font. A title using mostly narrow letters may display in full on an actual results page even past 60 characters, while one using wide letters could truncate earlier, though this tool judges both purely by character count.
• Image preview needs a full absolute URL. Only a value starting with http:// or https:// and containing no spaces renders as an image; a relative path such as /images/og.png falls back to a plain placeholder. The tool also never checks whether the image URL actually loads or meets the roughly 1200 by 630 pixel size commonly recommended for Open Graph images.
• Platforms can override submitted metadata. Google sometimes writes its own title or snippet instead of using the supplied title tag or meta description, and social platforms cache Open Graph data after the first fetch, so a page updated after being shared once may keep showing an outdated preview until that cache expires.
• Copy preview text copies three lines only. The copy button copies the title, description, and URL as plain text; it does not copy the image address, the site name, or any HTML meta tag markup.

Frequently Asked Questions

Does this tool fetch my website?

No. It is a manual preview checker, so it does not scrape or request external URLs.

Is the Google preview exact?

No. It is an approximate visual preview. Google may rewrite titles or descriptions.

What title length is best?

Around 50-60 characters is usually safer, but clarity matters more than hitting an exact number.

What description length is best?

Around 120-160 characters is often practical. Keep it useful and specific.

Can I preview social cards?

Yes. Add an image URL and site name to preview Open Graph and X/Twitter-style cards.

Why does my image not show a preview?

The image field needs a complete address starting with http:// or https:// and no spaces. A relative path or a broken URL falls back to a plain placeholder instead of an image.

Why did Google show a different snippet than what I typed here?

Google can generate its own title or description from page content when it judges the supplied tags less useful for a specific search query, so the live result can differ from this preview.

What does Copy preview text actually copy?

It copies the title, description, and URL as three plain text lines. The image address, site name, and any HTML meta tag code are not included.
