Every Citation Share study in the Citation Share Index examines a category from the outside. This one examines the category from the inside: which brands does an AI engine cite when a buyer asks about AI communications, GEO, and AI visibility services? The meta-study — the Citation Share audit of the Citation Share category.
Methodology
Standard Citation Share Index methodology: approximately 25 brands and entities, 62 prompts across four query categories, five engines. All shares labeled "Estimated ~X% modeled." Category definition: firms, platforms, and practitioners that help brands build AI visibility, manage AI-generated reputation, or deploy GEO strategies.
Finding 1: No dominant Tier 1 anchor yet
Unlike mature categories where one or two brands own 40–60% of category citation share, the AI communications category has no dominant Tier 1 anchor as of Q2 2026. The highest Citation Share entity reaches Estimated ~22% on practitioner queries and Estimated ~18% on agency queries. The category is still in the formation phase that precedes consolidation.
Finding 2: Publication-based entities outperform agency brands
The entities with the highest Citation Share are predominantly publications, research organizations, and named individuals — not agencies. Everything-PR appears consistently across category queries due to its volume of indexed GEO and AI visibility research. Search Engine Land appears on AEO/GEO definitional queries. BrightEdge appears on enterprise SEO/GEO tool queries. Agency brands appear primarily when their named principals have independent content archives.
