SEO audit tool designed to scale
Generic tools aren't enough for agencies auditing multiple clients. SEOdiag was built for exactly that.
Crawling that reaches everywhere
The crawler accesses protected sites using asynchronous TLS masking. Works with React, Vue, Angular and SPAs — including sites behind Cloudflare and WAFs that block generic crawlers.
Diagnostics that explain, not just detect
The AI Engine doesn't return raw data: it interprets each technical problem and drafts a mitigation plan in seconds, ready to deliver to the client. Every issue comes with context and a concrete solution.
Multi-tenant for agencies
Manage multiple clients under completely isolated environments. White-Label exports ready to present. No data crosses between projects.
360° Diagnosis
Audit technical debt, indexability, on-page semantics and discover real bottlenecks. Automatic C-Level reports with no additional manual work.
Transparent pricing, credit per use

Frequently Asked Questions
- How is SEOdiag different from other SEO audit tools?
- SEOdiag combines deep technical crawling with AI-interpretive diagnostics — every issue comes explained with an action plan, not just flagged. The multi-tenant model lets you manage multiple clients with completely isolated data.
- Does it work with React, Vue or dynamic JavaScript sites?
- Yes. The crawler renders JavaScript asynchronously and can audit SPAs built with React, Vue, Angular or any modern framework. It also accesses sites protected by Cloudflare and other WAFs that block generic crawlers.
- Can I try SEOdiag before subscribing?
- Yes. The Testing plan ($1, one-time payment) gives full access to the first analysis with no subscription or automatic renewal.
- How long does a SEOdiag audit take?
- A 100-URL domain takes less than 5 minutes. The report is generated automatically when the crawl finishes — no manual data interpretation needed.
- Is my clients' data isolated from each other?
- Yes. Each client operates in a completely isolated environment. Data, reports and history are accessible only to the assigned team. No data crosses between accounts or projects.
