Getting Started with SEOdiag
Last updated: 2026-07-22
Welcome to SEOdiag
SEOdiag is the specialized B2B technical SEO audit and AI citability (GEO/AIO) SaaS platform designed for agencies, consultants, and in-house teams who need audit diagnostics at scale without local RAM limitations or desktop software installations.
Unlike legacy desktop crawlers, SEOdiag does not just dump raw metrics; it interprets technical debt and AI search visibility using advanced language models (Claude 3.5 by Anthropic).
Step-by-Step Guide: Launching Your First Audit
To analyze a project from your dashboard, follow these steps:
1. Start a New Crawl
- Log into your dashboard at seodiag.com/app.
- Select New Audit from the left navigation menu or header CTA.
- Enter the exact root URL of the target website (e.g.,
https://www.example.com).
2. Configure Audit Parameters
- Page Limit: We recommend 1,000 URLs for initial scans, or the maximum cap supported by your credit balance for large e-commerce platforms.
- Crawl Depth (BFS): Defines how many click layers away from the homepage the spider will explore.
- Respect Robots.txt: Keep enabled to simulate real Googlebot crawl behavior.
3. Asynchronous Cloud Execution
Clicking Launch Crawl dispatches the job to distributed cloud clusters.
💡 Architecture Note: You do not need to keep the browser tab open or leave your computer running. The scan operates completely in the background.
Coverage Matrix: Analyzed SEO Vectors
During every scan, SEOdiag automatically checks over 60 critical technical vectors:
| Category | Evaluated Vectors | Max Severity |
|---|---|---|
| Indexation | Robots.txt rules, Noindex tags, Canonical tags, Reciprocal Hreflang | 🔴 Critical |
| Redirects | 301/302 chains, Redirect Loops, HTTP/HTTPS protocol mixing | 🔴 Critical |
| Architecture | Click depth, Orphan pages, Broken internal links (404) | 🟠High |
| Performance | Core Web Vitals (LCP, CLS, INP), Render-blocking assets, WebP compression | 🟠High |
| Semantics & GEO | Duplicate/missing Titles, Weak H1 headings, Schema.org validation | 🟡 Medium |
Frequently Asked Questions
How long does a technical audit take in SEOdiag?
A standard 1,000-page audit takes approximately 45 to 90 seconds thanks to SEOdiag's asynchronous cloud crawling architecture.
Do I need to install desktop software to use SEOdiag?
No. SEOdiag is 100% cloud-based in your browser. Crawling executes on remote server clusters, allowing you to turn off your computer without interrupting the process.
What happens if the target site is protected by Cloudflare or a WAF?
SEOdiag's crawling engine includes automated WAF evasion (Cloudflare 403) with rotating headers and headless cloud rendering, preventing false blocks.
