Search is changing faster than most people realise
In 2022, "SEO" meant one thing: ranking on Google. Today, the question has shifted. Your potential customers are not just Googling: they are asking ChatGPT, Gemini, Perplexity, and Claude. These AI models do not rank pages. They synthesise answers. And the sources they draw from are not necessarily the ones that rank number one.
This is the gap that GEO (Generative Engine Optimisation) is designed to close.
What signals make a site AI-visible?
The sites that AI models reliably cite share a consistent set of signals:
- Author and entity clarity: AI models prefer sources with identifiable authors, organisation schema, and about pages that establish who is behind the content
- Factual density: pages that state specific facts, statistics, and definitions get cited more often than pages that speak in generalities
- Freshness: content with a recent modified date is weighted higher, particularly for fast-moving topics
- Structured data: JSON-LD schema markup (Article, FAQPage, HowTo, Product) gives AI models unambiguous signals about what a page contains
- AI crawler access: if GPTBot, ClaudeBot, or PerplexityBot are blocked in your robots.txt, no AI engine can read your content regardless of its quality
How we calculate the GAIO Score
AngryRobot Scanner checks 70+ individual signals across AI visibility and technical SEO. The results are combined into three scores:
- GAIO Score: how well your site is positioned for AI answer engines: crawler access, structured data, E-E-A-T trust signals, and more
- SEO Score: technical search health: performance, indexability, meta signals
- Overall Score: a weighted combination of both
Each score runs from 0 to 100. The GAIO Score is the number that tells you where you stand with AI search specifically, and it is the one most sites have never measured.
GAIO Score and SEO Score: complementary, not competing
A high GAIO Score does not replace a high SEO Score, and vice versa. The best-performing sites in AI-era search tend to score well on both. Technical health matters to crawlers. Content clarity and trust signals matter to AI. AngryRobot Scanner shows you both in a single report so you can prioritise the fixes that move both needles.
