Meta Tag Generator

Generate meta, Open Graph and Twitter tags with a live search preview.

Build the tags that control how your page appears in Google and on social media, and see exactly how it will look before you publish. The preview measures pixel width the way Google does, so you know what actually gets cut off.

Everything you enter stays in this browser tab. Nothing is sent to our servers, logged or stored.

About Meta Tag Generator

Meta tags are how a page introduces itself. The title and description decide whether someone clicks your result instead of the nine others on the page, and the Open Graph tags decide what appears when your link is pasted into Slack, WhatsApp, LinkedIn or a group chat. Neither is a ranking factor in any direct sense — they are a click-through factor, which is often worth more.

The preview here measures pixel width rather than counting characters, because that is what Google actually does. A title of 60 capital letters is far wider than 60 lowercase ones, so character-count previews tell you a title is fine when it will be visibly cut, or tell you it is too long when it fits comfortably. Widths come from the Arial metrics Google renders desktop results in.

The generated markup is deliberately short. Most generators emit thirty tags and roughly six of them do anything: `keywords` has been ignored by every major engine for more than a decade, `revisit-after` was never honoured by anything at all, and `author` does nothing for ranking. Those are left out and explained rather than padded in to look thorough.

How to generate meta tags

  1. Enter your title and description

    The search preview updates as you type, showing where Google would truncate on both desktop and mobile.

  2. Add your URL and share image

    Both must be absolute URLs. Social crawlers fetch them from their own servers, so a relative path resolves to nothing.

  3. Check the warnings

    Missing alt text, http image URLs and contradictory robots directives are flagged with the reason they matter.

  4. Copy the HTML

    Paste the block into the <head> of your page. No libraries and no build step required.

Writing a title that earns the click

  • Put the important words first. If the title is cut, the end disappears — so a brand name at the front costs you the words people searched for.
  • Match the phrasing people actually use. A page titled 'Image Optimisation Utility' loses to one titled 'Compress Images Online Free' every time.
  • One title per page, genuinely different from every other page on the site. Duplicated titles are a common reason pages fail to rank against each other.
  • Google rewrites roughly a third of titles anyway. A clear, accurate one is far less likely to be replaced than a stuffed one.

Why your share image is not showing

By far the most common cause is a relative URL. Your browser can resolve `/og.png` because it knows the page it is on; Facebook's crawler is fetching from its own servers and has no such context. It must be a full `https://` URL.

The second most common cause is caching. Every platform caches Open Graph data aggressively, so a fix made after the first share will not appear until the cache clears. Facebook's Sharing Debugger and LinkedIn's Post Inspector both let you force a refresh.

Also check the size. 1200×630 is the safe ratio across platforms, and images under 200×200 are ignored entirely by most of them.

Frequently asked questions

Do meta keywords still matter?

No. Google confirmed it ignores the keywords meta tag in 2009, and Bing treats stuffing it as a negative signal. It is not generated here because adding it teaches people that noise is normal. The words that matter belong in your title, description and page content.

Why does the preview cut my title at a different place than other tools?

Because this one measures pixels rather than characters. Google truncates at roughly 580 pixels on desktop, and characters have very different widths — 'W' is more than four times the width of 'l'. Character-count tools are guessing at an average that most real titles do not match.

Should I write a meta description for every page?

For pages you want clicks on, yes. Without one Google composes a snippet from your page body, which is sometimes fine and sometimes lifts a navigation menu or a cookie notice. Writing it yourself is the only way to control the sales pitch.

Does a longer description rank better?

No. Description length has no effect on ranking at all — it only affects what people see. Anything beyond the width Google displays is simply cut, so the practical advice is to make the visible part compelling and not worry about the rest.
