GEO GLOSSARY
How consistently a brand appears across different AI providers — for example OpenAI, Gemini and Perplexity — rather than being visible to only one.
Different providers train on different data, retrieve from different indexes and are updated on different schedules. A brand that looks strong in one provider’s answers and absent in another does not have durable AI visibility — it has gotten lucky with one model’s current snapshot of the world.
With only one provider in a scan, there is no comparison to make, so cross-model presence is not meaningful and its weight is excluded from the overall score in that case. It only becomes informative once at least two providers have returned successful answers to compare.
