Meta Tag Generator

About the Meta Tag Generator

Fill in your page title and description, choose robots rules and add a canonical URL: the tool writes the matching <head> tags as you type and shows roughly how the page could look in Google on desktop and mobile.

Length is checked in pixels, not just characters, because Google cuts titles and snippets to fit the screen width — a title full of wide letters like "W" and "M" runs out of space long before one full of "i" and "l". Every robots rule follows Google's published specification, and the tool explains conflicts (for example nosnippet overriding max-snippet) instead of silently writing them.

Common uses

• Writing titles and descriptions for new pages, blog posts and product pages.
• Checking that a title is not cut off in results before you publish.
• Generating correct noindex, nosnippet or max-snippet rules without memorising the syntax.
• Producing the X-Robots-Tag header for PDFs and images.

Which tags Google actually uses

From Google's list of supported meta tags:

• <title> — the main source for the title link in results, together with headings and other signals.
• description — sometimes used for the snippet, when it describes the page better than text from the page itself.
• robots / googlebot — indexing and snippet rules. index, follow is the default and never needs to be written.
• viewport — tells mobile browsers how to lay out the page; Google treats its presence as a sign the page works on mobile.
• charset — the character encoding; Google prefers UTF-8.
• <link rel="canonical"> — your preferred URL when the same content is reachable at several addresses.

Google ignores the keywords meta tag entirely and does not use the lang attribute to detect language (it reads the text) — but browsers, screen readers and translation tools do use lang, so it is still worth setting.

How long can a title or description be?

Google says there is no limit on the length of a <title> or meta description, but results are "truncated as needed, typically to fit the device width". It does not publish a pixel or character number.

This tool estimates the rendered width with Arial character widths at 20 px for titles and 14 px for descriptions, and compares it with the limits most SEO tools use: about 600 px for desktop titles, about 920 px (two lines) for desktop descriptions and about 680 px for mobile descriptions. Treat these as guides: put the words that matter first, so a cut-off ending costs nothing.

Robots rules at a glance

• noindex — do not show the page in search results.
• nofollow — do not follow the links on the page.
• nosnippet — no text snippet or video preview (also keeps the text out of AI Overviews as a direct input).
• max-snippet:[n] — at most n characters of snippet; 0 means none, -1 means Google decides.
• max-image-preview:none|standard|large — size of image previews. Google Discover recommends large.
• max-video-preview:[n] — at most n seconds of video preview; -1 means no limit.
• noimageindex — do not index images on the page.
• notranslate — do not offer a translated result.
• indexifembedded — allow indexing when embedded in another page via iframe; only works together with noindex.
• unavailable_after: [date] — stop showing the page after a date.

When rules conflict, the more restrictive one applies. Google no longer uses noarchive or nositelinkssearchbox. Source: Google's robots meta tag specification.

Limitations

• Pixel widths are estimates. Real results depend on fonts, bold query words and the screen, and Google may rewrite titles and snippets.
• The preview approximates a Google result; it is not a screenshot and does not predict ranking.
• The tool does not fetch your live page — browsers cannot read other websites for security reasons (CORS). Type your values or paste the page’s HTML source instead.
