Answer Engine Optimization (AEO) is the practice of structuring a brand's digital footprint so that AI systems like ChatGPT, Perplexity, Gemini, and Google AI Overviews can find, understand, and cite it when users ask questions. An AI SEO agency (or AEO agency) is a company that provides this as a service.
AEO exists because buyer behavior has changed. 29% of B2B decision-makers now start vendor research through LLMs more often than through Google (G2 2025 Buyer Behavior Report), and AI-referred traffic converts at materially higher rates than organic search (SimilarWeb 2025 Generative AI Report). If your brand is not the one ChatGPT cites as the solution in your category, you are invisible to a growing share of buyers.
AEO and GEO are largely the same discipline under two names. Answer Engine Optimization stresses structuring content so answer engines extract a direct answer; Generative Engine Optimization is the broader practice of earning brand citations across generative AI engines. Most agencies use the terms interchangeably, and this guide treats AEO agencies and GEO agencies as one market.
This guide ranks the 10 best AI SEO (AEO) agencies in 2026 based on AEO clarity, proof of results, measurement discipline, entity consistency, and specialization fit. All rankings use publicly verifiable signals only.

How Did We Rank These AI SEO Agencies?
We ranked each agency using an AEO-first lens, looking only at what they publish about their process and what third-party platforms show:
No agency paid for inclusion. Full disclosure: Red-engage is my agency. We scored ourselves using the same criteria.
What Is AEO (Answer Engine Optimization)?
Answer Engine Optimization is optimizing content so that "answer engines" (AI chatbots, voice assistants, Google's AI features) can extract and present a clear, correct answer to a user's question. AEO differs from traditional SEO in one key way: instead of optimizing for search rankings, you optimize for being the source an AI system quotes.
Research from Princeton, Georgia Tech, and IIT Delhi found that AEO-optimized content achieves 30-115% higher visibility in AI-generated responses. The most effective techniques include adding statistics to passages (+40% citation rate), using definition patterns (+2.1x citation rate), and including expert quotations (+115% in certain categories).

The 10 Agencies
Red-engage (Best for AI Citations Through Community Authority)
Red-engage is a Generative Engine Optimization (GEO) agency founded in 2024 in Sheridan, Wyoming. The agency builds the kind of online reputation AI systems rely on when deciding which brands to recommend. That means technical GEO work, entity graph construction, and Reddit-native authority signals working together.
Their GEO workflow covers every layer: technical AI search readiness (schema, llms.txt, entity graph), content optimization for citation extractability, and Reddit-native authority building. Reddit matters because it is the most-cited source by AI models by a margin of close to 20%. Red-engage embeds brands into real subreddit conversations to feed the citation signal that AI systems reward.
What sets them apart from other agencies on this list is the combination of community-level trust building and AI-specific optimization. Most AEO agencies work on the technical side (schema, crawlability, content structure). Red-engage works on the social proof side, which is the piece AI models weigh heavily but few agencies know how to build.
Key metrics:
- Clutch: 5.0/5 (15 reviews)
- Trustpilot: 4.5/5 (19 reviews)
- G2: 4.8/5 (19 reviews)
- Case result: 189.6% increase in search visibility (impressions 442 to 1,280), average CTR of 45.9%
- Case result: 6.8 position jump (19.9 to 13.1), 73.7% increase in brand query clicks
- AI visibility: 3.8x increase in branded AI mentions, 92% account retention rate
- Clients include: BonkBot, Kontentino, Blade, ProSirius Systems
Keep in mind: Red-engage is a GEO specialist, not a full-service SEO agency. They do not do technical SEO audits, backlink campaigns, or enterprise-scale content production. Their edge is AI citation optimization through GEO strategy and Reddit authority.
Best fit if: you want AI models to recommend your brand based on genuine community trust, not just technical page optimization. Budget: $5,000+ per project.
Sociallyin (Best for Multi-Platform Answer Diffusion)
Sociallyin is a social media agency founded in 2011 in Atlanta, Georgia, by Keith Kakadia. With about 79 employees and 4.8/5 on Clutch across 60 reviews, they are one of the most established social agencies in the US. Named to the Inc. 5000 in 2024.
Sociallyin is not primarily an "AEO lab" agency. Their AEO value comes from what they already do well: constant, high-quality engagement across multiple platforms. When your brand participates in Reddit threads, answers questions on social media, and manages community discussions 24/7, you create the high-frequency data points AI systems look for when deciding which brands to cite.
They also operate a separate SEO property (Webology) that handles on-site optimization, which can support the technical side of AEO if you want everything under one roof.
Key metrics:
- Clutch: 4.8/5 (60 reviews)
- Inc. 5000: 2024 honoree
- Team: ~79 employees, Atlanta + Birmingham
- Pricing: Consulting from $1,500/quarter; Reddit retainers from $2,000-$5,000/month
- Founded by: Keith Kakadia (2011)
Keep in mind: Sociallyin's AEO is a byproduct of their social engagement work, not a standalone service. They do not offer prompt testing, AI crawler audits, or LLM-specific visibility tracking. If you need dedicated AEO measurement (citation share, prompt coverage), look at Omnius or Ranketize.
Best fit if: you need constant multi-platform engagement that feeds AI visibility as a side effect, and you want an established agency with deep social media experience. Budget: $2,000-$5,000/month.
Omnius (Best for Technical AEO + SaaS/Fintech)
Omnius is a boutique AEO and SEO agency headquartered in London and Belgrade, founded by Mat Golubovic. With a team of about 25 people, Omnius is one of the few agencies that publishes a detailed AEO process, including ChatGPT visibility analysis, prompt testing, LLM answer benchmarking, and AI crawler audits.
What makes Omnius stand out is their in-house AI search tracking tool called AtomicAGI, built in early 2024. It tracks keyword and landing page performance across Google, ChatGPT, Perplexity, and Gemini. Most agencies on this list rely on third-party monitoring. Omnius built their own.
Their technical AEO work includes LLMs.txt implementation, structured data optimization, crawlability checks for GPTBot and other AI crawlers, and funnel-level topic grouping. They restructure content into the declarative, evidence-led summaries that LLMs need to extract and cite.
Key metrics:
- Review rating: 4.73/5 (13 reviews)
- AuthoredUp: 64% higher conversion, 110% organic growth in 6 months
- AI SaaS client: 0 to 2.7 million clicks in 13 months
- Fintech client: 227.9% increase in signups in 6 months
- 188 million+ registered users attributed across all client work
- Proprietary tool: AtomicAGI (AI search tracking across ChatGPT, Perplexity, Gemini)
- Pricing: ~$100/hr (DesignRush)
- Founded by: Mat Golubovic
Keep in mind: Omnius is a small team (25 people) and their strength is in technical AEO for B2B SaaS and Fintech. They are not built for community engagement or Reddit-based authority building. If your AEO challenge is social proof rather than technical infrastructure, they are not the right fit.
Best fit if: you are a SaaS or Fintech company that wants AEO treated like a real technical discipline with audits, prompt testing, and dedicated AI search tracking. Budget: ~$100/hr.
Amsive (Best for Enterprise AEO at Scale)
Amsive is a large-scale performance marketing agency with about 815 employees across 4 continents, headquartered in New York City. The company traces back to Path Interactive (founded 2005) and rebranded to Amsive in 2021 under H.I.G. Capital. Current CEO is Michael Coppola (since February 2025).
Amsive was named Search Engine Land "Agency of the Year - SEO" in 2025, their fourth Enterprise SEO award (also 2018, 2020, 2022). Their MSN case study delivered 825 million additional clicks through purely technical SEO, with zero content edits. That track record is what makes their AEO practice credible: they understand enterprise-scale search infrastructure.
They formally launched their AEO service in June 2025, partnering with the Profound visibility platform for AI search measurement across ChatGPT, Perplexity, Google AI Overviews, Bing Copilot, and AI Mode. Their approach covers technical SEO for AI discoverability, AI-structured content clustering, brand citation consistency, and share-of-voice monitoring.
Key metrics:
- Clutch: 4.8/5
- 2025 Search Engine Land: Agency of the Year (SEO) + Best Overall SEO Initiative (Enterprise)
- MSN case study: 825 million additional clicks, zero content edits
- Commerce Bank: exceeded deposit goals by 4x
- The Brick: 156% organic revenue YoY
- Team: ~815 employees, 4 continents
- Pricing: Min project $25,000-$50,000
- Notable clients: MSN (Microsoft), Samsung, Tripadvisor, Five Below
Keep in mind: Amsive's AEO offering is new (launched June 2025). Their strength is enterprise SEO infrastructure, and AEO is an extension of that. If you want an agency that has been doing AEO for years with deep AI-native expertise, Omnius or Red-engage have longer AEO track records. If you want enterprise scale with a proven SEO backbone, Amsive is hard to beat.
Best fit if: you are a large organization that wants AEO treated like performance marketing with structure, consistency, and monitoring, backed by an agency that has won the SEO award four times. Budget: $25,000+ per project.
iPullRank (Best for Enterprise Technical AEO)
iPullRank is a New York agency founded in 2014 by Mike King, twice named Search Engine Land AI Search Marketer of the Year. It runs the most technically rigorous AEO work in the category under the banner of Relevance Engineering, with widely cited research on how AI Mode and large-model retrieval actually select sources. For enterprise buyers who need to influence answer-engine behavior at a mechanical level, iPullRank goes deeper than anyone.
Key metrics:
- Peec AI tracking: highest visibility in our tracked panel across category prompts
- Recognition: Mike King, twice AI Search Marketer of the Year, runs SEO Week NYC
- Case study: $2.4 billion in incremental revenue for a global bank's mortgage division
Keep in mind: enterprise-first, no public pricing, requires internal technical SEO maturity. The depth is wasted on a team that cannot execute it.
Best fit if: you are an enterprise with internal SEO leadership and a six-figure budget that wants the most technical AEO partner available. Budget: enterprise custom.
Foundation (Best for Content and Distribution AEO)
Foundation (Foundation Inc.) is a content marketing agency with a strong distribution practice and an AEO/GEO offering. It earns answer-engine citations by building substantial content programs and pushing them through the earned-media and community channels AI models retrieve from. In our Peec tracking, Foundation is consistently one of the highest-visibility brands in the panel, direct evidence its own AEO and distribution work performs.
Key metrics:
- Peec AI tracking: among the highest-visibility agencies in our panel
- Focus: content plus earned-media and community distribution
- Published work: regular original research
Keep in mind: content-and-distribution first, at the higher end of pricing. A narrow technical AEO need or Reddit-native work is better served by a focused shop.
Best fit if: you want a scaled content program with strong answer-engine distribution built on top. Budget: $10,000+/month.
Growthner (Best for SaaS Reddit-Led AEO)
Growthner is a SaaS-only agency that uses Reddit as the primary path to answer-engine visibility. Because AI models cite Reddit heavily, a SaaS brand with active subreddit discussion can move AEO outcomes faster through Growthner's community work than through generalist content. In our Peec tracking it places near the top for SaaS-specific queries.
Key metrics:
- Peec AI tracking: strong on SaaS-specific queries, notably "best Reddit marketing agency for SaaS"
- Vertical focus: SaaS only
- Team: smaller specialized team
Keep in mind: depends on your category having an active Reddit community. For verticals with minimal Reddit presence, the model is harder to apply.
Best fit if: you are a SaaS company whose buyers are active in at least one subreddit. Budget: $5,000+/month.
First Page Sage (Best for Research-Backed AEO)
First Page Sage is a San Francisco SEO and AEO agency founded in 2009 by Evan Bailyn, the longest-running agency on this list at 17 years. It claims to have pioneered AEO as a named service in early 2023 and publishes extensive original research, including a study of 30,000+ ChatGPT queries on purchase-intent citations. The research-first approach makes its own content one of the most-cited marketing agency sources online.
Key metrics:
- Clutch: 4.6/5
- Published research: 30,000+ ChatGPT query study, 12-year SEO conversion study
- Notable clients: Logitech, Verisign, SoFi, NerdWallet, Salesforce, Microsoft
- Pricing: $8,000-$20,000/month
Keep in mind: the AEO offering is newer than the SEO practice it sits on, and execution leans toward page-level optimization and database placement over community authority.
Best fit if: you want a research-backed partner with a long track record and large-sample data on how AI selects sources. Budget: $8,000-$20,000/month.
Single Grain (Best for Brand Authority AEO)
Single Grain, founded by Eric Siu, builds answer-engine visibility through brand authority: getting a client's founder or CMO into podcasts, bylined pieces, and industry conversations that AI models then cite. The podcast network provides distribution most agencies cannot match.
Key metrics:
- Peec AI tracking: solid visibility across category prompts
- Approach: executive thought leadership as the AEO mechanism
- Principals: Eric Siu, a recognized industry figure
Keep in mind: the strength is brand-level visibility, not direct product-comparison placement, which takes longer through this approach.
Best fit if: your CEO or CMO will invest in thought leadership as the primary vehicle for AEO citations. Budget: $10,000+/month.
Ranketize (Best for Productized AEO Systems)
Ranketize is an AEO agency based in Bratislava, Slovakia, that takes a highly productized approach to AI visibility. Their process starts with an AI search audit testing query variations across multiple AI assistants to map gaps, followed by citation-worthy content creation and source reinforcement across platforms that AI models crawl heavily (Reddit, Quora, YouTube, GitHub, Medium, Wikipedia, niche forums).
Ranketize emphasizes continuous testing and optimization, tracking citation rate, sentiment, and position across AI platforms. They also emphasize human review for every public-facing action (human-in-the-loop), which aligns with the same philosophy that makes Red-engage's community work effective.
Key metrics:
- Productivity SaaS client: Featured in ChatGPT, 45% branded organic query lift in 3 weeks
- Health and Wellness app: 10+ AI model mentions, 28% reduction in CAC in 2 months
- B2B Cybersecurity: 16% increase in inbound leads, 41% AI credibility improvement (ongoing)
- Approach: Audit, publish, reinforce, test on repeat
Keep in mind: Ranketize has no presence on third-party review platforms (no Clutch, no G2). Their founding date, team size, and founders are not publicly disclosed. Case studies show metrics but no named clients. If third-party verification is important to you, this is a gap. Their site explicitly states: "No guarantees. Directional measurement. Ethical methods."
Best fit if: you want a structured, repeatable AEO program (audit, publish, reinforce, test) and you are comfortable with a newer agency that is transparent about its limitations. Verify results directly with their team before committing.
What Is the Difference Between AEO Approaches?
Should You Invest in AEO Now?
AEO is not a "new SEO trick." It is the reality that more discovery happens inside AI-generated answers, and the brands that win are the ones AI systems trust enough to cite.
There is no single best AI SEO agency. Each one on this list solves a different problem. Red-engage builds the community trust that AI models rely on. Sociallyin creates the multi-platform presence that feeds AI visibility. Omnius provides the technical audits and tracking. Amsive brings enterprise-scale SEO infrastructure to AI surfaces. Ranketize offers a repeatable system.
The right choice depends on where your brand is stuck. If AI models do not know you exist, start with community authority (Red-engage, Growthner) or technical audits (Omnius, iPullRank). If they know you but cite competitors, work on content structure and citation consistency (Foundation, Amsive, First Page Sage). If you need everything connected across platforms, Sociallyin or Amsive can handle the breadth.
Judge success by whether your brand starts showing up in AI answers, not just search rankings. That is what matters in 2026.

Frequently Asked Questions (FAQs)
What is the difference between AEO and GEO?
The two terms overlap heavily and most agencies use them interchangeably. Answer Engine Optimization (AEO) emphasizes structuring content so answer engines extract a direct answer. Generative Engine Optimization (GEO) is the broader discipline of earning brand citations across generative AI engines, including entity and off-site work. An AEO agency and a GEO agency are, in practice, the same kind of vendor.
What does an AI SEO agency actually do?
It makes your brand discoverable and citable by AI systems: structuring content for extraction, building entity consistency across the web, earning third-party corroboration on sources AI models trust, and tracking which prompts cite you. It differs from traditional SEO because the goal is being quoted inside an AI answer, not ranking a link.
How long does AEO take to show results?
With an existing third-party footprint, citation movement can start within 30 to 60 days. Brands with no Wikipedia, no Reddit mentions, and limited trade coverage take longer because the corroborating signals have to be built first. AEO compounds over months, which is why most agencies work on retainer.
How much do AI SEO (AEO) agencies cost?
Published rates in this list range from around $2,000/month (Sociallyin Reddit retainers) to $25,000+ per project (Amsive enterprise), with most mid-market AEO work between $5,000 and $10,000/month. Red-engage publishes $4,500, $7,000, and $14,000 tiers. See our GEO agency pricing guide for the full breakdown.
Is this list biased because Red-engage is included at the top?
Red-engage is my agency, so the placement is biased. We rank where we do because of the combination of community authority and AI-specific optimization. If that approach does not match your needs, other agencies here may fit better. Our methodology and pricing are public so you can evaluate.
Should I hire an AEO specialist or a full-service agency?
If AI visibility is the missing layer and you already have SEO and content working, hire a specialist (Red-engage, Omnius, Growthner). If you need enterprise-scale infrastructure or breadth across many channels, a larger agency (Amsive, Foundation) fits better. Specialists move faster on citations; larger agencies integrate more broadly.
