Your deploy succeeded.
Did your site actually work?
Favicon ignored by Google. Link previews broken. Sitemap missing. Nothing errors — it all just silently fails. Deploy Checker scans your URL and flags every post-deploy problem with the exact Next.js fix.
- Favicon meets Google's real requirements (48px rule, stable URL, not robots-blocked)
- OG & Twitter tags render — with live link preview
- og:image loads, correct 1200×630 size, absolute URL
- Sitemap present, valid, and submitted-ready
- robots.txt actually allows what you think it does
- Canonical tags point at the right domain
Free at launch. No spam — one email when it's live.
Built by a solo dev who shipped a site and stared at a gray globe in Google for three weeks. Read the story: Why your favicon doesn't show in Google Search →
