November 10, 2025 — Leads & Copy — Resonance has launched GEO Search, a free tool designed to provide B2B brands with insights into how generative AI models perceive them during the buying process and what factors drive their visibility.
Built on a research project in B2B technology marketing, GEO Search analyzes over 100,000 buyer-intent prompts run through large language models (LLMs) and generates over 946,000 brand mentions from 34,000 companies, categorizes 1 million URL citations, and benchmarks 113 B2B tech sectors.
The findings indicate that AI search is establishing a new competitive arena where public relations and earned media determine a brand’s presence in LLM-generated buying recommendations. According to Forrester, 89% of B2B buyers use LLMs such as ChatGPT, Claude, and Gemini during their vendor research.
Unlike traditional search engines that provide a list of links, AI models generate a single answer that influences vendor selection. Claire Williamson, Founder and CEO of Resonance, emphasized that brands not visible in AI answers are essentially invisible to buyers.
The GEO Study identified four key constants:
1. Earned media drives AI visibility: Publications are the primary sources that LLMs cite for vendor shortlisting.
2. Analyst reports and peer-review sites such as G2, Gartner, IDC, and TrustRadius dominate during the evaluation phase.
3. Visibility varies by sector: Cybersecurity, DevOps, and Cloud Infrastructure buyers consult different sources; therefore, a single algorithm is insufficient.
4. LLMs follow patterns that can be influenced by identifying and leveraging trusted sources within each category.
Tom Fry, CTO and co-founder, explained that LLMs follow patterns that can be influenced by understanding which sources AI trusts in each category and shaping visibility accordingly. The research indicates citations and brand mentions are the new clicks in AI search.
GEO Search introduces a new category, a GEO Search Engine, which reveals buyer questions inside LLMs, provides real-time answers generated by LLMs, exposes competitor mentions, and frames brand positioning. Users can enter their brand or category to see how AI responds and compare the AI ‘shortlist’.
Resonance is offering GEO Search free to the public to help brands understand their presence in AI-driven research. The tool reveals new competitors, potential misframing, and instances where brands are entirely missing from AI answers. Resonance also provides AI visibility programs for B2B technology brands, focusing on buyer narrative ownership and content strategies.
The methodology included analyzing 113 B2B tech segments with 500 buyer-intent queries per segment, covering awareness, evaluation, and purchase decisions. Queries were run in buyer context, and LLM outputs were analyzed for brand mentions, URLs cited, and source types. Segments followed 12 intent types, including informational, benchmarking, comparison, purchase decision, technical evaluation, risk/compliance, and community validation.
