A meta tag generator that builds the SEO and social tags a page needs, title, description, canonical, robots, Open Graph and Twitter Cards, with a live Google-style search preview as you type.
Meta tags are how a page describes itself to search engines and social platforms. Get them right and your page shows a compelling title and snippet in search results and a rich preview card when shared; get them wrong and it looks broken or gets truncated.
Everything runs in your browser; nothing you enter is uploaded.
Length is shown live because search engines cut off text that is too long. Aim for roughly 50 to 60 characters for the title and 150 to 160 for the description; the counters turn red when you exceed the limit.
Open Graph and Twitter Card tags control the preview when a page is shared: the title, description and image. Open Graph is used by Facebook, LinkedIn and many others, while Twitter Cards are used by X.
Only the fields you fill in are emitted, and every value is HTML-escaped, so the generated tags are safe to paste straight into your page head without breaking the markup.

标题和描述影响搜索结果中的点击，规范标签和 robots 标签引导索引。Open Graph 和 Twitter 标签有助于社交分享，而非直接影响排名。
