SEO audits in minutes: what to check and fix
The on-page and performance signals that actually move rankings — and how an AI coworker surfaces them with ready-to-paste fixes.
A useful SEO audit isn't a 40-page PDF. It's a short list of real problems and the exact fixes.
On-page signals that matter
- Title & meta description — present, unique, the right length.
- One H1 and a sane heading structure.
- Alt text on meaningful images.
- Canonical pointing to the right URL.
- Structured data (schema) for rich results.
- Crawlable content — a homepage that renders text, not an empty JS shell.
Performance signals
Real Core Web Vitals — LCP, CLS, INP — from a measurement tool, not a guess. "Feels slow" doesn't help; "LCP 3.8s, target under 2.5s" does.
From audit to action
The value isn't the diagnosis — it's the fix. A good audit hands you the rewritten title, the ready meta description, the alt-text pattern, the schema snippet. An AI coworker can run this on any URL and produce the fixes you paste in, while honestly flagging anything it couldn't measure.
