The meta tag handbook

Meta tag generator and social preview tool for every platform

Meta tags are the invisible instructions that tell search engines and social platforms how to present your page. Get them right and your link shows a compelling title, a clear description and a properly sized image. Get them wrong and it appears as a bare URL or, worse, a truncated mess with the wrong picture. A meta tag generator and preview tool removes the guesswork by showing you the result before you publish.

This free tool generates the full set of tags you need, from the classic title and description through Open Graph for Facebook and LinkedIn, Twitter cards for X, and the smaller details that matter for WhatsApp, Discord and Slack. Every change updates a live preview of each platform's card, so you see exactly what your audience will see and can tune the wording and image dimensions until the card looks right.

There is also a site health audit that scores your tags against common SEO and content fundamentals and suggests specific improvements. Everything runs in your browser, so your draft URLs and copy are never uploaded, and the generated tags can be copied straight into your page head.

Quick answer

A meta tag generator creates title, description, Open Graph and Twitter Card tags and previews how a link appears on Google, Facebook, X, LinkedIn, WhatsApp, Discord and Slack. ToolGuest builds and audits tags live in the browser, free, with no signup and no upload.

Why it matters

Why previewing your tags beats guessing

Each platform renders a link differently. Google shows a title, a URL and a description snippet. Facebook and LinkedIn draw a large card with an image, a title and a description. X switches between a large image card and a compact summary. Discord and Slack render an embed with their own styling. Writing one set of tags and hoping it suits all of them is how links end up looking broken.

Truncation is the silent killer. A title that runs past the platform's limit is cut off mid-sentence, and a description that is too long loses its call to action. A live preview shows exactly where the cut falls, so you can front-load the words that matter and keep the meaning intact.

Images decide whether anyone clicks. A card image that is too small is replaced by a fallback, one with the wrong aspect ratio is cropped, and one that is missing entirely leaves an empty box. Previewing the card against the recommended dimensions catches all three problems before they reach your audience.

FAQ

Meta tag questions, answered

What are meta tags?

Meta tags are pieces of HTML in a page's head that describe the page to search engines and social platforms. They control the title, the description snippet and the image shown when the link is shared.

What is the difference between standard meta tags and Open Graph?

Standard tags such as title and description serve search engines. Open Graph tags serve social platforms, defining the title, description and image used in a shared link card. Twitter cards are a parallel set for X.

Why does my shared link show the wrong image?

Most commonly the og:image URL is missing, too small, or has the wrong aspect ratio, so the platform falls back to another image or none at all. The preview here shows the recommended dimensions so you can fix it.

How long should a title and description be?

Keep titles within roughly sixty characters and descriptions within about one hundred and sixty so they are not truncated. The live preview shows exactly where the cut-off falls for each platform.

Does it check my tags for problems?

Yes. The site health audit scores your tags against common SEO and content fundamentals and lists specific improvements.

Is my data uploaded?

No. Everything is processed in your browser. Your draft URLs and copy are never transmitted, logged or stored.

Can I copy the generated tags?

Yes. The complete tag set is produced in copy-ready form so you can paste it straight into your page head.

Is the tool free?

Yes. It is completely free, needs no signup and carries no ads or tracking.
