Methodology

Data is from the October 2026 EMARKETER AI Visibility Index. In October 2026, EMARKETER analyzed 6,560 ChatGPT recommendations and 6,560 Google Gemini recommendations in response to US-based interactions across 28 B2B agency and marketing technology categories: ad agencies, media agencies, PR and communications agencies, social media agencies, influencer marketing agencie, programmatic ad buying platforms, retail and commerce media platforms, web and app analytics platforms, customer data & identity platforms, performance marketing agencies, search marketing agencies, affiliate marketing agencies, commerce media and retail marketing agencies, CRM and life cycle marketing agencies, branding agencies, experiential marketing agencies, digital marketing agencies, publisher monetization platforms, creative technology platforms, marketing measurement platforms, data clean rooms, ad verification platforms, consent management platforms, brand measurement platforms, affiliate marketing platforms, product feed management platforms, tag management systems, and data management. Each interaction asked ChatGPT and Google Gemini for product recommendations using standardized prompts (e.g., "best advertising agency," "customer data platform for audience targeting"). Prompts varied by product type, product attribute, consumer need, target audience, and price tier to capture a representative range of consumer questions for each category.
