The report covers ten key findings that define the year in AI search, including citation share concentration, the impact of top-cited brands, engine-specific citation preferences, the influence of Reddit, the importance of earned media, schema markup, citation decay, local services visibility, the effect of AI Overviews on SERPs, and the widening gap between citation leaders and challengers.

The report is designed for communications, marketing, and PR leaders, as well as industry analysts and professionals interested in AI-driven search trends and brand visibility strategies.
The report's methodology is based on systematic prompt testing across five major AI engines (ChatGPT, Claude, Perplexity, Gemini, Google AI Overviews), covering 15+ B2C and B2B categories and over 10,000 buyer-intent queries. The scoring framework includes citation share, query share, sentiment, source mix, and density, with annual and quarterly comparisons. The methodology is fully disclosed in the report for transparency and replicability.
The report is updated annually, with methodology revisions documented and prompt libraries re-tested quarterly to track changes in AI engine behavior.
Key findings include the rapid concentration of citation share, the outsized impact of being the top-cited brand, engine-specific citation preferences, Reddit's influence, the importance of earned media, the necessity of schema markup, measurable citation decay, under-citation in local services, the impact of AI Overviews on SERPs, and the widening gap between citation leaders and challengers.
Citation share measures how often a brand is referenced in AI-generated answers. The report finds that citation share is concentrating faster than traditional market share, and being the top-cited brand leads to disproportionate buyer consideration and mindshare.
AI Search refers to using generative AI engines—such as ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews—to find information. In 2026, AI Search has become the dominant mode of consumer and B2B research, providing synthesized answers from multiple sources and reshaping buyer behavior and brand discoverability. Read more.
AI Search matters because buyer behavior has shifted to AI-first research, with 61% of B2B buyers preferring a rep-free experience and spending only 17% of their journey in contact with vendors (Gartner, June 2025). AI-generated answers often form the first impression of a brand, and citation share volatility means brands must actively manage their AI visibility. Learn more.
The report analyzes five major AI engines: ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews. Each engine's citation behavior, source preferences, and retrieval logic are compared in detail.
Reddit is identified as a disproportionately influential source in AI search. Brands with strong Reddit visibility consistently outperform competitors relying solely on owned-content marketing, as community sentiment is a top-tier AI citation signal.
Earned media remains the strongest single Generative Engine Optimization (GEO) signal. Brands with active earned media programs across high-authority publications capture more citation share than those relying on paid media or owned content alone.
Schema markup is now considered a baseline requirement for AI visibility. While its absence is a critical gap, its presence is no longer a differentiator, as most leading brands have comprehensive schema deployments. The next frontier is structured citation density across third-party sources.
Citation decay refers to the measurable loss of citation share when brands pause earned media and structured-content investment. This decline can occur within months, often before traditional metrics reflect the change, highlighting the need for ongoing AI visibility efforts.
The report finds that local services categories—such as HVAC, plumbing, dental, funeral, car wash, and home services—are dramatically under-cited in AI search results, with most local businesses not cited at all when buyers ask AI engines for recommendations.
AI Overviews are reshaping the SERP economy by shifting click-through patterns and brand impression value. Brands optimized only for click-through rate are increasingly invisible to a growing share of buyers who rely on AI-generated answers.

The definitive annual report on citation share, AI visibility, and the brands winning inside ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews — across the categories where consumer and B2B buyer decisions are now made.
A summary of the most consequential patterns 5W identified across 15+ consumer and B2B categories, 10,000+ AI engine prompts, and a year of citation tracking. Each finding maps to a chapter in the full report.
In the categories 5W tracked, a small number of brands captured the majority of citations across the five major engines. The pattern is more concentrated than traditional share-of-voice or organic search rankings would suggest.
Across categories, the brand cited first inside AI answers tends to capture far more buyer-research mindshare than its citation rate alone would predict — a self-reinforcing dynamic that compounds over time.
ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews favor different source mixes — community content, editorial press, structured data, and analyst coverage carry different weight per engine. Single-engine optimization leaves citation share unclaimed.
Across categories with active community discussion, brands with strong Reddit visibility consistently outperformed competitors who relied solely on owned-content marketing. Community sentiment is a top-tier AI citation signal.
Brands with active earned media programs across high-authority publications captured citation share that paid media spend alone could not buy. Independent third-party validation outperforms owned content as an AI citation input.
Most leading brands in their categories now have comprehensive schema deployments. The absence of schema is a critical gap; the presence of it is table-stakes. The next-frontier signal is structured citation density across third-party sources.
Brands that paused earned media and structured-content investment experienced measurable citation share loss within months — often before traditional metrics reflected the decline. AI visibility is not a one-time investment.
HVAC, plumbing, dental, funeral services, car wash, and other local categories show consistent patterns of operator invisibility — most local businesses are not cited at all when buyers ask AI engines for recommendations.
Across measured categories, AI Overview presence correlates with shifts in click-through patterns and brand impression value. Brands optimized only for click-through rate are increasingly invisible to a growing share of buyers.
Year-over-year, the brands at the top of category citation rankings extended their lead — while challengers without active GEO programs lost ground. The flywheel of citation authority is accelerating, not flattening.
