I built this after watching a client site lose most of its organic traffic because someone left a <meta name="robots" content="noindex"> tag in the header component. It was there for two weeks before anyone noticed.

LintPage checks your staging URL for common SEO mistakes that block search engines:

- NOINDEX meta tags - robots.txt with Disallow: / - Missing or invalid SSL - Broken internal links - Missing title tags, meta descriptions, canonical URLs - Basic accessibility issues (alt text, ARIA)

It's a simple fetch + parse with JSDOM on the server side. No browser automation, so it's fast.

Tech stack: Next.js 15, Supabase, deployed on Vercel.

I'm looking for feedback on: 1. What other checks would be useful? 2. Anyone have horror stories about staging configs making it to production?
