Most AI visibility tools stop at measurement. They provide a dashboard and leave interpretation to the customer. 3RD goes further. The brand defines the outcome it wants in AI answers. 3RD diagnoses the root cause of why the brand is winning or losing the prompts that matter across ChatGPT, Perplexity, Gemini, Claude and Google AI. 3RD then translates that diagnosis into a Playbook of briefs and priorities the team can ship. Measurement is the start. Movement is the point.

Traditional SEO helps you rank on search engines. We help you appear in AI answers. Large Language Models (LLMs) don't just index pages — they synthesize knowledge. 3RD specializes in Generative Engine Optimization (GEO) and Answer Engine Optimization (AEO), ensuring your brand is cited, trusted, and correctly represented in AI systems.

We measure AI visibility using our Quality Score framework, which analyzes how large language models understand, mention, and rank your brand across systems like ChatGPT, Gemini, Copilot, Claude, and Perplexity. It combines three key scores: Visibility Score (how often your brand appears), Relevance Score (how accurately it's described and positioned), and Authority Score (how strong and up to date the cited sources are). Together, they form a single Quality Score that benchmarks your performance across the Agentic Internet, shown in a live dashboard with trends, competitor comparisons, and the prompts and sources driving your visibility.

Yes. We can track, benchmark, and optimize multiple brands, regions, or product lines under one visibility framework — ideal for multinational organizations, portfolio companies, or agencies managing several clients.
