Meta tag generator
Fill in the title, description, and image, and get code ready to paste into your <head>: meta description, canonical, robots, Open Graph, X card, languages, and structured data. See how it will look on Google, Facebook, WhatsApp, X, and LinkedIn, with a review that tells you what to improve.
We read the title, description, canonical URL, robots, Open Graph, X, alternate languages, and structured data. No script in the pasted code is run.

1Title and description
We do not use artificial intelligence: we take whole sentences from your text up to the recommended limit, without making anything up.
The full, final address of this page.
2Social media
Ideal size: 1200×630 px. It must be a full, public address.
It is off so your browser does not request anything outside this page. If you turn it on, it requests the image from that address to show it and measure its size.

3Search engines and browser
One per line: the language code, a space, and the full address. We add the current version if it is missing.
4Structured data (JSON-LD)
Structured data helps Google understand the page and can produce rich results.
Paste the code inside the <head> tag of your page. If your site uses a content management system, look for its SEO or metadata fields. Remember that the <html> tag must also include the language, for example lang="en-US".
How to use it
- Type your page title and description. The bars show the character count and the estimated pixel width against Google’s limit.
- Add the canonical URL, the language, and the address of a 1200×630 px image. Choose the content type and the X card. You can also start with “Import” by pasting the <head> of a page that is already published.
- Switch between Google, Google mobile, Facebook and WhatsApp, X, and LinkedIn to see the preview, and fix whatever the review flags: errors and warnings tell you what to change and why.
- If you need it, add structured data with the JSON-LD builder (organization, article, product, FAQ, local business, or breadcrumbs) or paste your own JSON.
- Copy the HTML or download it, and paste it inside the <head> tag of your page. Save drafts on your device to pick them up later.
Frequently asked questions
Is my content sent to any server?
No. The form, the previews, and the review all run in your browser. Drafts are saved only on your device. The one possible request is for your image: to show and measure it in the preview, your browser requests it from the address you typed, and you can turn that option off.
What is the ideal length for the title and the description?
Google shows about 580 pixels of title and about 920 of description, which usually works out to 50-60 and 120-160 characters. That is why we measure the real width of the text and not just the letters. It is an estimate: Google may rewrite what it shows depending on the search.
What size should the sharing image be?
1200×630 pixels, with a 1.91:1 ratio, as a JPG or PNG and with a small file size. It needs a full, public address, not a relative path. If you load it in the preview, we tell you its real size.
What are the Open Graph and X tags for?
They control how your link looks when it is shared on Facebook, WhatsApp, LinkedIn, and X: title, description, and image. Without them, each network makes up a summary that often looks wrong. With “summary_large_image” the image is shown large.
What is the canonical URL and when do I need it?
It is the main address of a page when the same content can be opened at several, for example with and without “www” or with parameters. It tells Google which one to index and avoids duplicate content. It must be absolute and use https.
How does “Suggest from a text” work?
It does not use artificial intelligence or make up content: it takes whole sentences from your text and stops before the recommended limit. If the first sentence is too long, it cuts it at a whole word and lets you know.
What meta tags are
Meta tags are tags in the <head> of a page that you do not see on it, but that describe its content to search engines and social networks. The main ones are the title (<title>), the description (meta description), the canonical address, and the instructions for robots.
What each group is for
- Search engines: the title, description, canonical, robots, and alternate languages (
hreflang) help Google understand and show your page. - Social networks: Open Graph and X cards define the title, description, and image that appear when someone shares your link.
- Browser: the viewport adapts the page to phones, the charset prevents problems with accented characters, and the theme color tints the mobile browser bar.
- Structured data: schema.org JSON-LD describes organizations, articles, products, or FAQs in a format that search engines read precisely.
Tips to get more clicks
Put the important part at the start of the title, because the end may get cut off. Write a different description for each page, and make it answer what the person is looking for. Use a sharp 1200×630 px image with alt text, and check the preview before you publish. Remember that changes in search engines and social networks can take a while to show up.
