I ran launch audits on 20 AI-built apps, Lovable, Bolt, v0, a couple of Cursor builds. Same checks on each, run against the live deployed URL, not the code. These were the most common problems:
14/20 had a canonical tag pointing at the wrong domain. Usually the builder's preview URL. The site works fine on the custom domain, but it's telling Google the real version lives at something.lovable.app.
Your domain never ranks and you'd never know why.
12/20 had broken or missing basic SEO. No meta description, no OG image (so every shared link is a grey rectangle), or a sitemap listing pages that 404.
9/20 had analytics installed but not firing. Added early, then the AI rewrote the layout and dropped the snippet, or it fires on the homepage and nowhere else. Traffic arrives, you learn nothing.
