Yet the industry lacks a principled way to determine whether enough data has been collected to support those comparisons. Collection budgets vary widely across studies and platforms, and conclusions are often drawn from rankings whose stability and precision are unknown. We introduce a sequential convergence framework based on two complementary criteria: rank stability evaluates whether the rank-correlation trajectory has reached a structural plateau, and structural sufficiency evaluates whether the spread of citation shares among established domains (those whose citation-share confidence intervals exclude zero) exceeds the uncertainty of those estimates. Together, these criteria distinguish rankings that have merely stabilized from rankings that are sufficiently resolved to support inference. Both criteria are derived from regularities already present in the observed citation distribution, including its rank structure, uncertainty profile, and the boundary between observed and established domains. The framework retains a small number of structural constants but requires no externally specified query count, correlation target, or CI-width target; the stopping decision is driven by directly observed measurement uncertainty and is robust across a range of sufficiency thresholds. Applied across 30 platform-topic combinations spanning Gemini, SearchGPT, and Perplexity, the framework adapts automatically to platform-and topic-specific citation distributions. The results demonstrate that no fixed collection budget can be justified across contexts and that convergence can instead be evaluated from the structure of the observed citation distribution itself. The framework provides a practical basis for determining when AI visibility measurements are ready to support comparative analysis.  \nCCS Concepts: Information systems → Information retrieval → Evaluation of retrieval results; Information systems → World Wide Web → Web searching and information discovery.  \nAdditional Keywords and Phrases: generative search, generative search optimization, answer engine optimization, AI visibility.  \n1 Introduction  \nThe purpose of AI visibility measurement is comparative analysis. Practitioners want to know which domains a generative search engine cites most often, how that standing changes over time, and whether observed differences are large enough to matter for competitive strategy. The goal is not the measurement itself, but the decisions that it is meant to enable.  \nThe industry quickly converged on a multi-query process for sampling multiple aspects of a topic and measuring how often a brand’s web pages are cited (or its name is mentioned) in generative  \nsearch responses. But the industry has paid far less attention to a critical question: whether the resulting measurements yield enough data to support the comparisons they are used to make. Collection budgets differ by nearly an order of magnitude across published studies and industry practice, with no principled basis for choosing one over another. Comparative conclusions are routinely drawn from measurements that may not be adequate to support them.  \nThe core difficulty is that citation share is a sample statistic, not a fixed quantity. Generative search engines are stochastic: the same query submitted on different occasions can produce different responses and cite different sources. A multi-query design is intended to average over prompt-level idiosyncrasies, but it also aggregates many variable outputs, so repeating the same
