What's Considered Comprehensive Coverage on GEO Platforms?

When evaluating AI search optimization platforms, comprehensive coverage means more than just monitoring all AI models - it means monitoring both the base model and search enhanced responses of AI models. Most GEO platforms only monitor AI models’ consumer apps, but Evertune monitors both consumer app responses and base model responses via AI models’ APIs.

The Three Categories That Matter

Base models represent the foundational AI systems that power agent experiences and developer applications. Evertune monitors ChatGPT, Gemini, Claude, DeepSeek and Meta through direct API integration. These models contain the core training data that influences how AI systems understand and recommend brands.

Consumer apps show how real users experience AI search in production environments. Evertune tracks ChatGPT Search, Gemini Search, CoPilot, and Perplexity. These platforms blend base model knowledge with real-time search results, creating hybrid recommendation patterns.

Search integrations capture how traditional search engines incorporate AI responses. Evertune monitors Google AI Mode and Google AI Overviews. These integrations reach billions of existing search users and represent the bridge between traditional SEO and Generative Engine Optimization.

Why Base Model Tracking Matters

Base models represent long-term brand building. Evertune is the only platform that can isolate base model knowledge from search-enhanced responses through direct API integration. This distinction matters because agent experiences are built on base models, inheriting their brand preferences and knowledge patterns.
