As GEO and AI search have grown, so has the number of specialists working across different areas of the field. That can make it difficult to know which experts are most relevant to follow and what sets them apart. To make the decision easier, our team evaluated 47 GEO and AI search specialists using the following criteria:
- Industry Influence (30%): Their role in shaping GEO and AI search practices, research, or industry discussion.
- Technical Expertise (22%): Background in LLMs, Retrieval-Augmented Generation framework, and AI architecture.
- Client Results (15%): Documented success improving brands’ presence in AI search, including case studies, positive client testimonials, and increases in AI-generated referrals.
- Media References (10%): Approximate number of citations in industry or other relevant publications.
- Years in AI and Search Optimization (10%): Combined experience in SEO and AI optimization
- LinkedIn Following (13%): Size of their LinkedIn following as an indicator of their industry influence.
After evaluating all 47 specialists, our team selected seven of the highest-scoring experts to include in the table below. You’ll also find an analysis of each expert along with an overview of their contributions to the field.

Evan Bailyn
Evan Bailyn founded First Page Sage in 2009 after graduating from Columbia University and writing two books on SEO for Pearson. He developed the first commercial GEO methodology in 2023 and has published more than 35 articles on GEO strategy which CMOs use to pivot their organizations from traditional search to AI-powered discovery. In 2025, he spoke at 12 major conferences and guest lectured at Stanford and Haas School of Business. His work has predominantly revolved around helping companies adapt their search strategies as AI platforms become a salient source of leads and brand exposure.
Bailyn’s main argument is that authoritative leadership content can work in both traditional search and AI search. The same expert-driven material that ranks well in search engines is also more likely to be cited by large language models, so one content program can support both channels. His research also points to other factors that can improve AI recommendations, including placement in highly ranked list articles, verifiable awards, and strong third-party reviews. First Page Sage uses these same factors in its work with clients in technology, healthcare, and financial services.
- Industry Influence: Founder of GEO Marketing, First Page Sage Founder and CEO

- Client Results: Wins for Salesforce, Microsoft, Chanel
- Media References: ~2,500

| Summary of Reviews |
| Industry peers describe Bailyn as “the architect of modern GEO strategy” with frameworks that are “immediately actionable for companies.” Some note his pricing is “on the higher end,” reflecting the value of his insights. |
Cyrus Shepard
Cyrus Shepard approaches GEO largely through research and testing. A former Head of Global SEO at Moz and former Google Quality Rater, he has firsthand experience with how search quality is evaluated, which informs his work at Zyppy. His body of research includes large-scale studies of AI citation ranking factors, a review of more than 75 published research papers, and a separate content audit of more than 400 websites.
Shepard tends to test assumptions about GEO against available data. One of his findings, that roughly 38% of AI Overview citations come from pages already ranking in the top 10, has been cited by outlets including BuzzStream and Position Digital and adds to the case for maintaining traditional SEO alongside GEO efforts. Shepard has limited client capacity, so brands looking for a full-service GEO partner may need to consider other options.
- Industry Influence: Founder of Zyppy; Former Head of Global SEO at Moz
- Technical Expertise: AI Citation Ranking Factors & Evidence-Based GEO
- Client Results: Wins for global SaaS and enterprise clients
- Media References: ~1,700
- Years in AI and Search Optimization: 15+
- Specialty: Data-driven AI citation research and GEO framework development
- LinkedIn Following: 38K+
| Summary of Reviews |
| Peers describe Shepard as “one of the few people in GEO who shows his work” and praise his “ability to translate dense research into actionable strategy.” Some note that his depth in citation research means his guidance can feel “narrow for teams looking for broader GEO strategy beyond organic visibility.” |
Aleyda Solís
Aleyda Solís has developed a vast body of work on international and multilingual search. Through Orainti, the consultancy she founded in 2014, she works with global brands on the differences in how search and AI systems operate across languages and markets. Her research has also examined how AI systems trained primarily on English-language data can produce biased results in other languages. This gives her work particular relevance for companies managing search across multiple countries.
Her frameworks are most useful for organizations already operating in several markets. On the flip side, regional or U.S.-focused companies are less likely to need the international and multilingual aspects of her work.
- Industry Influence: International Expert
- Technical Expertise: Multilingual AI
- Client Results: SEO / GEO success with global enterprises
- Media References: ~1,690
- Years in AI and Search Optimization: 18+
- Specialty: International & multilingual GEO
- LinkedIn Following: 124K+
| Summary of Reviews |
| International brands praise Solís’s “global expertise” and “practical multilingual frameworks.” Some note “guidance is most actionable for organizations already operating across international markets.” |
Lily Ray
Lily Ray has analyzed major Google algorithm updates for more than a decade, and that record of pattern recognition anchors her authority on AI search. She is VP of SEO Strategy and Research at Amsive, where she leads a team of more than 35 specialists. In 2026, she launched Algorythmic, a consultancy focused on AI search, E-E-A-T, and Google Discover. USA Today named her the most influential SEO expert of 2022, and she has presented at MozCon for five consecutive years.
Much of Ray’s work examines the factors that affect whether brands appear in AI-generated results, particularly signals related to content quality and authority. Her background in Google algorithm analysis is especially useful for established brands looking at how their existing search authority carries over into AI search. Her work is less applicable to newer companies that have not yet established those signals.
- Industry Influence: Founder of Algorythmic, VP of SEO Strategy & Research at Amsive
- Technical Expertise: AI Quality Signals
- Client Results: Successful consulting for Fortune 500s
- Media References: ~900
- Years in AI and Search Optimization: 16+
- Specialty: Search quality & AI trustworthiness
- LinkedIn Following: 59K+
| Summary of Reviews |
| Colleagues praise Ray’s “deep quality insights” and “practical E-E-A-T guidance.” Some note that her advice is “less actionable for brands trying to optimize for non-Google AI engines.” |
Kevin Indig
Kevin Indig spent years leading SEO and growth at Shopify, G2, and Atlassian before moving into advisory work with companies including Ramp, Reddit, and Dropbox. Through Growth Memo, he publishes original research on SEO and AI search. His work includes a framework for assessing whether a brand’s presence in AI results is likely to persist over time, as well as research on the difference between being cited by an AI system and having the brand itself named in the response.
Indig works primarily as an advisor rather than handling implementation, which means that companies will likely need an internal team capable of putting his recommendations into practice. His work may also be harder to apply for companies that have not yet built a strong SEO foundation.
- Industry Influence: Growth Advisor
- Technical Expertise: LLM Traffic Patterns
- Client Results: Wins with Ramp, Reddit, and Dropbox
- Media References: ~1,260
- Years in AI and Search Optimization: 15+
- Specialty: AI search metrics & business impact
- LinkedIn Following: 64K+
| Summary of Reviews |
| Growth leaders appreciate Indig’s “metrics-focused approach” and “business-first perspective.” Some note that his research is more “valuable as a diagnostic tool than a tactical playbook,” and teams looking for step-by-step GEO implementation guidance may find “his frameworks require more interpretation.” |
Wil Reynolds
Wil Reynolds is the founder and Co-CEO of Seer Interactive, a B Corp-certified digital marketing agency with more than 200 employees that he launched in 2002. Seer has conducted studies analyzing more than 350 factors correlated with LLM visibility across industries, with findings cited by Forbes, eMarketer, Fast Company, and Search Engine Land. Reynolds has also argued that GEO measurement should go beyond tracking brand mentions in AI responses and connect those mentions to pipeline and revenue.
Seer has documented growth in AI referral traffic across enterprise client accounts and published case studies based on its GEO experiments. Much of that work depends on a level of data infrastructure that many organizations do not yet have, so teams without that foundation may find the approach difficult to reproduce in full.
- Industry Influence: Founder/Co-CEO of Seer Interactive (200+ person agency); LinkedIn Top Voice (Jan 2026)
- Technical Expertise: Data-Backed GEO & LLM Visibility
- Client Results: GEO wins with enterprise clients
- Media References: ~800
- Years in AI and Search Optimization: 24+
- Specialty: Data-driven GEO and AI search ROI measurement
- LinkedIn Following: 45K+
| Summary of Reviews |
| Peers appreciate Reynolds’s “data-first approach to GEO” and his “transparency in sharing both results and methodology.” Some note that Seer’s GEO practice is “still maturing relative to its established SEO reputation.” |
Ross Simmonds
Ross Simmonds treats presence in AI search as a distribution problem rather than an on-page one, a thesis he lays out in his Amazon best-selling book Create Once, Distribute Forever. He has also argued that Reddit plays an important role in both organic and AI search. His advice to brands is to understand how their niche appears on the platform and participate in those communities instead of approaching them strictly as marketers.
Through Foundation Marketing and Distribution.ai, Simmonds applies that distribution-focused approach to content strategy. His work is most applicable to companies that already have a strong library of content to distribute. Conversely, brands with thin or underdeveloped content libraries may need to strengthen what they have before expanding their distribution.
- Industry Influence: GEO Conference Speaker
- Technical Expertise: Distribution Strategy
- Client Results: Success with Canva, Jobber, Procore
- Media References: ~1,150
- Years in AI and Search Optimization: 10+
- Specialty: Content distribution for AI visibility
- LinkedIn Following: 62K+
| Summary of Reviews |
| Marketers value Simmonds’s “practical distribution frameworks” and “data-backed strategies.” Some note that his Reddit-first playbook is “harder to execute for brands in regulated or niche B2B industries.” |
