What this tool does

Free, browser-based SEO meta tag generator. Fill in the form on the left, get a ready-to-paste `<head>` block on the right — title, description, canonical URL, Open Graph (og:title / og:description / og:image / og:type / og:url), Twitter Card (summary or summary_large_image), author, robots, theme-color, language, and a Schema.org JSON-LD `<script>` block (WebSite or Article depending on og:type). Live length warnings flag titles past 60 characters (Google truncates) and descriptions past 160. Three real preview cards mirror what the page looks like as a Google SERP snippet, a Facebook share card, and a Twitter summary card — so you spot a wrong og:image dimension or an overlong title before deploy. 100% client-side: no upload, no account, no analytics on your inputs.

Real-world use cases

  • Shipping a Next.js landing page and the Slack preview shows a blank card

    You paste the staging URL into Slack and the unfurl is a gray box with no image. Fill the form here, set og:type to website, point og:image at a 1200x630 PNG, and copy the head block into your layout. The Facebook preview card on the right shows exactly how the unfurl renders, so you catch a missing og:image before the demo.

  • A blog post that needs Article JSON-LD without hand-writing the script

    You publish 3 posts a week and Search Console keeps flagging missing structured data. Set og:type to article, fill headline, author, and image, and the tool emits a ready Article JSON-LD block with headline, author, inLanguage, and datePublished. Paste it once into your post template and every future post inherits valid markup.

  • Auditing 40 legacy pages where titles run 75+ characters

    An SEO audit flags dozens of pages with titles Google truncates. Paste each title into the form, watch the length warning fire past 60 characters, and trim until it clears. The SERP preview shows the exact desktop snippet, so you tune the wording to read well at 58 characters instead of guessing pixel widths in a spreadsheet.

  • Handing a non-technical marketer a copy-paste head block

    Your marketer owns the campaign copy but cannot touch the codebase. They fill title, description, and image URL in this form, copy the generated block, and drop it into the CMS head field. No build step, no plugin license, no waiting on an engineer to translate their copy into og: and twitter: tags by hand.

Common pitfalls

  • Using a relative og:image path like /og.png. Crawlers need an absolute URL such as https://yoursite.com/og.png, or the share card renders blank.

  • Copying the same 60-character title into both the title tag and og:title without trimming. og:title can run longer, but a 90-char title tag still gets truncated in SERPs.

  • Forgetting twitter:card defaults to nothing, so a rich image becomes a tiny thumbnail. Set summary_large_image when you want the full 1200x628 banner on Twitter.

Privacy

Everything runs in your browser. The title, description, URLs, and image links you type stay in the page and are never uploaded to any server. Your inputs are encoded into the shareable URL so a link reproduces your exact tags, which means anyone with that link sees the same values. If a field holds something you would not put in a public URL, clear it before copying or sharing the link.
