How is the Authority Score calculated?
Our Authority Score is a proprietary composite metric (0-100) that weighs five dimensions: Technical SEO (20%), Content Quality (20%), Structured Data (20%), AI Visibility (25%), and Trust Signals (15%). It goes beyond traditional DA by including AI engine citation data.
What is AI Visibility and why does it matter?
AI Visibility measures how often AI search engines like ChatGPT, Perplexity, Gemini, Claude, and Grok cite your website in their responses. As AI search grows, being cited by these engines is becoming as important as ranking on Google.
How accurate is the schema validation?
Our validator checks your JSON-LD against official Schema.org type definitions, validates required properties, and catches common structural errors. It covers the most widely used schema types including Organization, WebSite, Article, Product, FAQ, and more.
What does the Content Analyzer measure?
The Content Analyzer produces two scores: a Share Score (measuring hook strength, headline power, emotional triggers, and shareability format) and a Citation Score (measuring content structure, factual density, entity clarity, and freshness). Together they form your Content Score — a combined metric of how likely your content is to be shared by humans and cited by AI engines.
Can I monitor my scores over time?
The free tools give you a one-time snapshot. To track your scores over time, set up automated audits, and receive alerts when your authority changes, create a free account and upgrade to one of our monitoring plans.
