The Problem
Every time you share a link on social media, the platform reads your meta tags to generate the preview card. Bad meta tags = ugly previews = fewer clicks.
Most meta tag checkers are either paywalled, slow, or show you raw HTML without context.
The Solution
I built Meta Tag Checker — a free tool that:
- Fetches any URL and extracts all meta tags
- Shows social previews — see exactly how your link will appear on Google, Twitter/X, and Facebook/LinkedIn
- Scores your SEO out of 100 with specific issues to fix
- Lists all meta tags in a clean table
What It Checks
- Page title (length validation)
- Meta description (length validation)
- Open Graph tags (og:title, og:description, og:image, og:url)
- Twitter Card tags (twitter:card, twitter:title, twitter:image)
- Canonical URL
- Language attribute
- H1 headings
- Word count
- Response time
Try It
Paste any URL and see your SEO score instantly. No signup, no limits, completely free.
Tech Stack
- Next.js 15 (App Router)
- TypeScript
- Tailwind CSS
- Server-side fetching (handles CORS)
- Deployed on Vercel
The server-side fetch is key — browser-based tools can't check most sites due to CORS restrictions. This tool fetches from the server, so it works with any public URL.
Why I Built This
I got tired of sharing blog posts on Twitter only to see broken preview cards. Now I check every URL before sharing.
