What Is SAGIScan?
SAGIScan is an AI website scanner that audits SEO, AEO, GEO, and ISO in 30 seconds flat.
SAGIScan is a website auditing platform that runs 175 specialized tests across SEO, Answer Engine Optimization (AEO), Generative Engine Optimization (GEO), and Industry Standard Optimization (ISO) — delivering per-page scores with prioritized fixes in under 30 seconds.
Built by SimpleBuild AI, the scanner deploys intelligent analyzers to audit every page across four pillars: Search Engine Optimization, Answer Engine Optimization, Generative Engine Optimization, and Industry Standard Optimization. Each test focuses on one specific signal — from schema markup and Core Web Vitals to chatbot citation readiness and security headers.
Unlike traditional tools such as SEMrush, Ahrefs, or Google Lighthouse, this platform doesn’t just test backlinks and keywords. It analyzes whether chatbots like ChatGPT, Claude, Gemini, and Perplexity can find and cite your business — covering chatbot visibility, generative search, and compliance categories that legacy crawlers completely ignore. According to Search Engine Land, chatbot-generated results now account for over 30% of discovery queries (2025 study). Google’s documentation confirms that structured data directly impacts rich result eligibility.
Key Features at a Glance
- Per-page scorecard — every page gets an individual 0–100 rating across all four pillars
- Severity-based prioritization — issues ranked as critical, high, medium, or low impact
- "Fix It For Me" service — click any issue to have our engineers resolve it within 48 hours
- Under 30 seconds — a 10-page site scans in ~26s, 50 pages in ~43s, 250 pages in ~90s
- Four-pillar coverage — the only scanner auditing search, chatbot, generative, and compliance signals in one report
Why Do Most Websites Fail Chatbot Visibility Tests?
89% of small business sites have zero AEO optimization, making them invisible to ChatGPT, Gemini, and Perplexity.
Generative engines are deciding whether to cite your business — or your competitor. Most sites fail silently.
Invisible to Chatbots
Generative engines cite 2–7 sources per answer. According to a 2025 study, sites without structured data and clear entity definitions are excluded from 89% of generative responses. Without proper extraction formatting, you’re invisible to the next generation of search.
Rankings Dropping
Google’s 2025 core updates weight INP, heading hierarchy, and schema completeness higher than ever. Sites with broken structured data, missing HSTS headers, or shallow content depth are losing positions weekly. Old "good enough" optimization doesn’t cut it anymore.
Losing to Competitors
Your competitors with proper schema, author entities, and optimized content are getting cited while you wonder why the phone stopped ringing. Our comparison with SEMrush shows 3x more issues found per audit.

Built by Search & Technology Engineers
This platform was created by Gary Amaral, Founder & CEO of SimpleBuild AI — a full-stack engineer and search marketing specialist with 15+ years of experience in SEO, paid media, and web application development. Gary has managed over $2M in annual ad spend across Google, Meta, and Microsoft platforms, and has built automated tools used by hundreds of small businesses.
The SimpleBuild engineering team includes specialists in natural language processing, structured data markup, and cloud infrastructure. Our scanner architecture uses Anthropic Claude Sonnet with 20 API keys running in parallel, enabling 175 simultaneous tests per page. The platform is hosted on Google Cloud Run with auto-scaling infrastructure.
We built this platform because existing tools like SEMrush ($130/mo), Ahrefs ($99/mo), and Moz ($99/mo) focus entirely on traditional SEO signals — backlinks, keyword density, page speed. They ignore that in 2025, chatbots drive over 30% of search discovery for local businesses (source: Search Engine Land). Our four-pillar model is the first scanner covering all visibility dimensions.

How is this scanner different from SEMrush or Ahrefs?
SEMrush ($130/mo) and Ahrefs ($99/mo) focus on traditional SEO — backlinks, keywords, page speed — using rule-based crawlers. They cannot evaluate chatbot visibility or compliance.

See the full comparison →
How long does a website scan take?
Under 30 seconds for most sites. Benchmarks: 10 pages ≈ 26s, 50 pages ≈ 43s, 250 pages ≈ 90s. Speed comes from parallel execution — all 175 tests run simultaneously across 20 Anthropic Claude keys on Google Cloud Run. Real-time progress shown as each test completes.
What industries does the scanner support?
Any business that depends on search visibility — home services, healthcare, professional services, and automotive. If customers find you through Google or chatbots, our four-pillar analysis identifies what’s holding you back. See all industry pages →
Does the scanner check for chatbot visibility?
Yes — the AEO pillar has 34 dedicated tests evaluating whether ChatGPT, Claude, Gemini, and Perplexity can find and cite your site. Tests include robots.txt crawler directives, entity clarity, FAQ schema, speakable data, E-E-A-T signals, and content freshness.
