Top 44 Digital Marketing Agencies in AI Answers — September 2026

Thrive Internet Marketing Agency dominates the ranking at 9.9% named across all engines, though its lead masks significant fragmentation in how engines recommend it. Claude and Grok both named it on 7.5% of prompts, but Perplexity named it on 25%—more than five times the rate of Google Gemini (4.8%) and double the rate of Google AI Overview (0%). Despite this visibility, Thrive was never cited from its own domain, meaning AI systems sourced all mentions of it from third-party sites. LYFE Marketing follows in second place at 5.7% named, appearing most frequently in Google AI Overview (10.3%) and Perplexity (10%) but never in ChatGPT or Google Gemini responses. Like the leader, LYFE received zero domain citations. WebFX ranks third at 4.3% named and stands out as the only top-10 brand with meaningful self-citation, appearing on its own domain in 9.4% of answers—nearly all of those from Grok's 22.5% recommendation rate. Disruptive Advertising (3.5%), NoGood (2.8%), and KlientBoost (2.1%) follow, each receiving consistent but low mentions across 2–5 engines.

The next tier includes brands named on roughly 2% of prompts: NinjaPromo, Siege Media, and SmartSites, each at 2.1% named. Siege Media and KlientBoost each earned minimal self-citations (1.9%), while SmartSites relied entirely on third-party sources despite being named on Perplexity's 7.5% of prompts. Belkins, Brafton, CIENCE, Single Grain, and Straight North all registered at 1.4% named, with Single Grain notable for appearing at position 5 on some lists despite its low overall rate. Brafton earned 1.3% self-citations and appeared across multiple engines, whereas CIENCE was named only in Claude and Grok responses. These ten brands—from Siege Media through Straight North—form a middle tier that occasionally appears but lacks the consistency of the leaders.

Demand Curve and Directive each registered 0.7% named, representing the threshold of minimal AI visibility. Demand Curve received no engine mentions above 2.5%, while Directive appeared in Google Gemini (4.8%) and Grok (2.5%) but not in three other engines. Below this point lies a large group of 28 brands that received zero mentions: 1stPage Rank, Accenture Interactive, BBDO, Boostability, Bruce Clay Inc., Coalition Technologies, Cramer-Krasselt, DDB, Deloitte Digital, Digitas, Epsilon, Grey, Growthink, Havas, Ironpaper, Merkle, Netmark, Ogilvy, Publicis.Sapient, Razorfish, SapientRazorfish, Search Laboratory, SeoClarity, Vertical Measures, Victorious, Viral Nation, Wpromote, and Wunderman Thompson. Several of these are major holding company brands (Ogilvy, Havas, Publicis.Sapient, DDB, Grey, BBDO) that were never named despite appearing on some engines' internal lists. Ironpaper and Coalition Technologies earned 1.3% self-citations despite zero naming mentions, suggesting they appeared as sources in answer chains without being highlighted as recommended agencies. This long tail represents the vast majority of tracked vendors and reflects the extreme concentration of AI recommendations on a small set of brands.

Engine behavior explains much of this concentration. ChatGPT named only a single distinct brand (Siege Media) across 40 prompts and provided no domain citations whatsoever, effectively returning no vendor recommendations to users in this category. Google Gemini named 5 distinct brands and Claude named 12, both relying on consistent inclusion of Thrive and a handful of secondary options. Perplexity demonstrated the widest reach, naming 14 distinct brands, but concentrated heavily on Thrive (25%) and WebFX (12.5%). Google AI Overview named 8 brands with a more even distribution, leading with LYFE Marketing at 10.3% rather than Thrive. Grok named the most brands at 19 distinct vendors but provided no citations at all, relying instead on inline recommendations. These differences mean that a user asking the same question across six engines would receive substantially different answers: Perplexity would strongly favor Thrive, Google AI Overview would emphasize LYFE, and ChatGPT would provide almost no vendor guidance.

The six engines diverge sharply in how many brands they recommend and how often they cite sources. ChatGPT is the most restrictive, naming only 1 brand across 220 answers and providing zero domain citations, making it non-functional as a discovery tool in this category. Claude and Google Gemini are similarly conservative, each naming 5–12 distinct brands; Claude leans toward Thrive (7.5%), while Google Gemini distributes mentions more evenly. Perplexity and Google AI Overview name 8–14 brands but concentrate differently: Perplexity puts 25% of recommendations on Thrive while Google AI Overview leads with LYFE Marketing at 10.3%. Grok is the most expansive recommender with 19 distinct brands named, but its recommendations are not evenly distributed—it heavily favors WebFX (22.5%)—and it provides no domain citations at all, returning only inline vendor suggestions.

Citation behavior separates the engines into two groups. Claude, Google Gemini, Google AI Overview, and Perplexity all provide domain citations, though at very low rates (0.1–1.5% of answers). Perplexity leads in citation frequency at 1.5%, meaning it still avoids citing vendor domains on 98.5% of answers. ChatGPT and Grok provide no domain citations; ChatGPT returns no recommendations and Grok returns only inline mentions. Across all engines, 80.5% of the 1,251 citations point to third-party aggregators rather than vendor sites, with Clutch.co leading at 59 citations. This means that even when an engine cites a source, it is far more likely to point to a review site than directly to an agency's website, amplifying the visibility of platforms like Clutch and DesignRush relative to individual vendor domains.
