Zero Data Retention

META TAG GENERATOR

Fill in a few fields and copy a complete, correctly escaped set of head tags, or paste a page's HTML source to see which meta tags it already has and what is missing. Nothing is fetched; everything works on what you type or paste.

Zero retention: your headers never leave this browser. Verify it yourself in DevTools.

About the Meta tag generator

How Can You Verify That Nothing Leaves This Browser?

You do not have to take our word that your HTML stay here. Developer tools show every request a page makes, so you can watch this page work and confirm that nothing is sent. The check takes under a minute.

  1. Open your browser developer tools with F12, or Cmd+Option+I on a Mac, and select the Network tab.
  2. Reload the page and let it finish. You will see the page's own files, its web fonts, and one anonymous page-view request. Nothing has been typed yet, so none of them can contain your HTML.
  3. Click the clear icon in the Network tab so that the log is empty.
  4. Paste page source into the inspector and generate tags.
  5. Look at the Network tab again. It is still empty. For extra proof, turn on offline mode after the page loads and every lane keeps working.

Only two things can add a line to that log, and neither carries your HTML. Submitting the feedback form sends the vote and comment you typed. Typing characters in a script the page has not displayed yet, such as Cyrillic or Greek, can make the browser fetch the matching font file, and that request names only the font.

2http never sends a request on your behalf: the request builder writes code for you to run, and the meta inspector reads source you paste instead of fetching a URL. The production site also sends a Content-Security-Policy header that tells your browser to refuse connections to anywhere except this site and the anonymous analytics endpoint.

What Tags Does the Generator Write?

  • The title element and the description meta tag.
  • A canonical link and robots directives: index or noindex, follow or nofollow.
  • Open Graph tags: og:title, og:description, og:type (website, article, or product), og:url, og:site_name, og:image with alt text, and og:locale.
  • Twitter card tags, with the card type and the @site handle.
  • theme-color for the browser interface on mobile.

Every value is HTML-escaped, so quotes and ampersands in a title cannot break the markup.

Why Does the Preview Not Show My Image?

Showing the image would mean loading it from its URL, which is a network request, and 2http sends none while you work. The social card preview shows the image URL as text instead, alongside the title, description, and site name, so you can still check how the card will read.

What Does the Inspector Find?

Paste the HTML source of a page, from View Source or a saved file, and the inspector lists what it contains:

  1. The title, description, canonical URL, robots, viewport, and lang attribute.
  2. All Open Graph and Twitter tags.
  3. The @type of every JSON-LD block, the icons, and hreflang alternates.
  4. Problems: a missing title, description, og:image, twitter:card, or canonical, lengths outside the usual ranges, and duplicated tags.

How Long Should a Title and Description Be?

Search results usually show about 50 to 60 characters of a title and 126 to 155 characters of a description before cutting them off. The counters turn to a warning outside those ranges. They are guidelines, not rules: a shorter title that says exactly what the page is beats a padded one. For a full-site SEO audit, crawling, and sitemaps, use 2seo.

Frequently Asked Questions

Does the inspector fetch my page?

No. Paste the HTML source yourself, from View Source or a saved file. 2http never contacts your site, so it works on staging and private pages too.

What size should an Open Graph image be?

Use 1200 by 630 pixels for a large card on most platforms, keep important content away from the edges, and add og:image:alt text describing the image.

Do I need both Open Graph and Twitter tags?

X falls back to Open Graph for the title, description, and image, so twitter:card is the one Twitter tag you really need. Adding the others gives you control if you want different text.

Where does a full SEO audit belong?

In 2seo, the 2suite SEO tool. This lane writes and inspects meta tags for one page; crawling a whole site and analyzing rankings is a different job.
