Building a Free AI Visibility Checker for Marketers and Site Owners
Published 1 August 2025 · GoContento
The Challenge
As AI-powered search and answer engines become more widespread, content teams and site owners need a way to evaluate how well their website is structured for AI discovery — without relying on proprietary black-box audits or paying for expensive platforms. There was no free, transparent, publicly accessible tool that scored AI-specific readiness signals.
Strategy
GoContento designed a deterministic scoring framework that evaluates 8 publicly measurable AI visibility categories: AI Crawl Accessibility, Entity & Brand Clarity, Structured Data, Content Citability, Authority & Trust, Content Structure, AI Discoverability Signals, and Freshness & Transparency. Each category has a defined point allocation totalling 100 points. The score is calculated entirely from signals readable on any public website — no proprietary data sources, no estimated scores.
Execution
The checker was built as a Next.js API route with full SSRF protection, including DNS resolution checks against private IP ranges and known cloud metadata endpoints. It fetches the target homepage, robots.txt, sitemap.xml, and llms.txt simultaneously with a 12-second timeout and 5 MB response limit. HTML parsing extracts JSON-LD schemas, heading structure, meta tags, internal/external links, and crawler directives. The front end shows a score ring, category breakdown bars, expandable check rows with what-we-found and how-to-improve detail, and a priority issues panel. All checks are deterministic — no randomness.
Results
The AI Visibility Checker is available free at gocontento.io/tools/ai-visibility-checker. It requires no account, produces results in under 15 seconds, and covers 25+ individual checks across the 8 categories. It clearly distinguishes between high priority issues, medium priority improvements, and passing checks, and includes contextual recommendations relevant to each specific finding.
