AI visibility tools answer three different questions. Is my site built so AI can read and trust it? How often does AI mention me? Is a change in those mentions real? Classic SEO suites answer the first question only partly. Daily trackers such as Peec AI and Profound answer the second, across many engines. The Three-Layer Approach (3LA) answers the first with deterministic structural scoring and the third with repeated sampling and confidence intervals. Most teams need more than one of these. The useful thing is to know which question each tool is actually answering.

Want your brand to be preferred and cited by ChatGPT, Perplexity and Google AI Overviews? This guide walks you through setting up 3la.ai in under an hour, so you can close visibility gaps, optimise your content and compete in AI search (GEO).

BrightonSEO's 10th anniversary edition, held October 8–9, 2026 and drawing roughly 4,500 attendees, was dominated by one theme: GEO (Generative Engine Optimization), AI citations, and agentic recommendations. For anyone building on the Three-Layer Approach, this wasn't new information - it was confirmation.
