Three things the incumbents can't match.
Sitechecker Pro and SEO Tester Online are fine. They're also expensive, paywalled, and haven't changed much since 2020. Here's our unfair advantage.
Zero signup, zero ads
Paste a URL, get a full report in seconds. No account creation, no paywalls, no upsells. Competitors lock every button behind a trial.
AI-prioritised fixes
DeepSeek reads your full audit and returns the 5 highest-impact fixes — with exact references to your specific issues. Works on targeted scans and the Full Audit alike.
