AI assistants such as ChatGPT, Gemini, Claude, and Perplexity are becoming critical discovery channels. Existing visibility tools — including Profound, Evertune, PEEC AI, Semrush, and AthenaHQ — often rely on snapshots of brand presence. While these provide directional insights, they lack reproducibility, auditability, and sustainability. The AIVO Standard™ offers a framework for AI Visibility Optimization (AIVO), supported by the Prompt-Space Occupancy Score (PSOS™) auditing system. This paper outlines limitations of snapshots, introduces PSOS methodology, contrasts approaches with examples, and discusses implications for SMBs, enterprises, and agencies. Appendices provide sample datasets, workflow diagrams, and cost estimates to ground the framework in practice.
