Share of LLM (SoLLM)

What Is Share of LLM?

More and more B2B decision-makers use AI systems for research and vendor comparisons — if your brand doesn’t appear there, you’re losing potential customers to competitors who are present in AI answers. Monitor your Share of LLM across different models and identify queries where you’re missing. Trade publications, guest contributions, and consistent expert presence on authoritative platforms strengthen your visibility in AI recommendations.

Share of LLM (SoLLM) is a specialized GEO metric for the B2B space. It measures how frequently a Large Language Model mentions or recommends a specific brand in business-relevant queries. Unlike the general Share of Model, SoLLM focuses on purchase decisions — prompts like “What’s the best CRM system for mid-sized companies?” or “Which SEO agency do you recommend?”

This metric is so important because more and more decision-makers use AI systems as their first stop for research. Studies show that B2B buyers increasingly consult ChatGPT and similar tools before turning to classic search engines or comparison portals. Those who don’t appear here lose potential customers before those customers even start a Google search.

To improve your SoLLM value, you need to systematically build your AI visibility. That means: create content with high fact density, use structured data, and ensure your brand appears in trusted sources that AI models use as training material. The more frequently and consistently your brand appears in high-quality sources, the higher your SoLLM will be.
