Meta Tag Generator — title, description, Open Graph and Twitter cards
Generate the full head block for a page, with live character counts against the limits that actually apply.
Free and instant — results appear in seconds. No sign-up, no limits, and nothing you type is stored.
Three separate systems read the metadata in your page head, and they do not share a format. Search engines want a title and description. Facebook, LinkedIn, WhatsApp and most messaging apps read Open Graph. X reads its own twitter: tags and falls back to Open Graph when they are absent.
The result is a fair amount of duplication for what is conceptually the same information, which is why it is worth generating rather than typing. Fill in the fields once and the tool produces all three sets consistently.
The character counters matter more than they appear to. A title that runs long is not penalised, but it is truncated — and a truncated title often loses the distinguishing part at the end.
Where the character limits bite
Take a page title for a hosting comparison article:

VPS and Dedicated Options Compared for 2025That is 108 characters. In a search result it renders as:
The Complete Guide to Choosing Web Hosting in Pakistan: Sha…Everything that distinguished it — the comparison, the server types, the year — is gone. The visible portion is generic.
Rewritten to fit:
Web Hosting in Pakistan: Shared vs VPS vs Dedicated (2025)57 characters, and every word survives. The distinguishing terms are now in the part people actually see.
The limit is not really a character count — search engines measure pixel width, so a title full of capitals and wide letters truncates earlier than one of the same length in narrow characters. Around 55 to 60 characters is a safe working figure.
Descriptions behave differently. Google rewrites them frequently, generating its own snippet from page content when it judges that a better match for the query. A good description is still worth writing, because when it is used it drives click-through, but treat roughly 155 characters as the visible budget and put the important part first.
One detail that catches people: og:image must be an absolute URL. A relative path is silently ignored by every platform, and the share preview falls back to whatever image the scraper happens to find — often a logo or, worse, nothing.
What each tag does
<title> — the clickable headline in search results and the browser tab. The single most important on-page element.
meta description — the snippet beneath it. No direct ranking effect; substantial influence on click-through when it is used.
canonical — declares the preferred URL when the same content is reachable at several addresses. Essential on sites with tracking parameters, pagination or print versions.
og:title, og:description, og:image, og:url — what appears when someone shares the link on Facebook, LinkedIn, WhatsApp, Slack or Discord.
twitter:card — controls the card format on X. summary_large_image gives the wide image; summary gives a small thumbnail.
Image dimensions
Open Graph images should be 1200 × 630 pixels, a 1.91:1 ratio. Smaller than 600 × 315 and most platforms fall back to a small thumbnail. Keep the file under about 5 MB, and preferably well under 1 MB.
Text inside the image gets cropped unpredictably across platforms, since each crops to its own aspect ratio. Keep anything that must remain readable well inside the centre.
Why your share preview is wrong
Almost always caching. Platforms fetch metadata once and hold it, sometimes for days. Editing the tags does not update an already-cached preview.
Each major platform provides a debugger that force-refreshes its cache — Facebook's Sharing Debugger, LinkedIn's Post Inspector, X's Card Validator. Run the URL through the relevant one after changing tags.
If the preview is wrong on first share, check that the tags are in <head> and not injected later by JavaScript. Most social scrapers do not execute JavaScript, so client-side rendered tags are invisible to them.
Tags not worth adding
meta keywords — ignored by every major search engine for well over a decade.
meta author, meta revisit-after, meta distribution — no effect.
meta robots with default values — index, follow is the default. Stating it changes nothing.
Adding these does no harm beyond clutter, but they contribute nothing.
Frequently asked questions
How long should a meta title be?
Roughly 55 to 60 characters. The real constraint is pixel width rather than character count, so a title in capitals or wide letters truncates earlier. Longer titles are not penalised, but the tail gets cut — so put the distinguishing words first.
Does the meta description affect rankings?
Not directly. It influences click-through rate when it is displayed, which matters. Google frequently rewrites descriptions, generating its own snippet from page content when it judges that a closer match for the query, so a well-written description is used sometimes rather than always.
Why is my Facebook share preview showing the wrong image?
Almost always caching. Platforms fetch Open Graph data once and hold it for days. Run the URL through Facebook's Sharing Debugger to force a refresh. If it is wrong on the very first share, check that og:image is an absolute URL and that the tags are in the HTML head rather than injected by JavaScript.
What size should the Open Graph image be?
1200 by 630 pixels, a 1.91:1 ratio. Below 600 by 315 most platforms fall back to a small thumbnail. Keep any essential text well inside the centre, since each platform crops to its own aspect ratio and edges get lost.
Do I still need meta keywords?
No. Every major search engine stopped using the keywords tag more than a decade ago. It does no harm, but it does nothing useful either.
Do I need both Open Graph and Twitter tags?
X falls back to Open Graph when Twitter tags are absent, so strictly you can omit them. Including twitter:card is still worth it because it lets you specify the card format explicitly rather than relying on inference.
