The problem
When sharing a link, social platforms build previews from Open Graph meta tags. Missing or wrong og:title, og:description or og:image leads to broken previews — often discovered only after posting.
What was built
OpenGraph Check is a web tool for validating and previewing Open Graph tags: enter any URL and see how the link appears on Facebook, X, LinkedIn, WhatsApp and Discord. Detect missing tags, check image dimensions and fix previews before sharing. Plus related SEO tools for favicons, sitemaps, robots.txt and canonical URLs.
My role
- Web app development with Next.js and TypeScript
- URL scanning and platform-specific preview rendering
- Tag validation and actionable improvement hints
- Additional SEO tools and guides
Outcome
A free toolkit for developers and marketers to preview social link cards — catch missing Open Graph data before it hurts click-through rates.
