The Best Generative Engine Optimization (GEO) Agencies

Last Updated on May 8, 2026 by Ewen Finser

TL;DR — which agency should you pick? If you want AI-first visibility built on UGC and community signals, go with ScaleVisible. If you’re a B2B or SaaS brand needing content authority that feeds GEO, pick Foundation. For AI-native GEO with proprietary tracking software, choose Passionfruit. If you want one full-service agency for SEO, GEO, PPC, and everything else, Coalition Technologies (mid-market, flexible) or WebFX (enterprise, 30-year track record) are your best options. For deep, sustainable SEO with AEO layered on top, Victorious is the specialist — though their $5K/month minimum makes them best for mid-market and up. Most retainers start at $4,000/month and services like Foundation often start at $12,000+.

Search engine optimization (SEO) isn’t quite as “dead” as many people claim, but it has definitely evolved. Generative AI has rewritten the rules of search visibility, and rather than competing for rank as they did in the olden days, brands are now competing to be cited and summarized by AI models.

Search has changed. Nearly half of B2B buyers now consult AI tools like ChatGPT, Claude, and Perplexity for vendor research before they ever click a Google result, and AI Overviews already appear in roughly 13% of US desktop searches — a number that has doubled in months. Gartner expects traditional search volume to drop by about 25% by 2026 as AI agents replace Google for product research, and WARC data shows 24% of marketers have already started shifting budget from SEO to GEO.

Generative Engine Optimization (GEO) and AI Search Engine Optimization (AISEO) are critical for any brand that wants to maintain visibility in search results. The best GEO/AISEO agencies have experience with technical SEO (which is still important), but they also understand how large language models (LLMs) interpret and surface content, helping brands to remain visible in AI-driven search.

Choosing the right GEO/AISEO agency can mean the difference between being the answer… and being invisible.

What Are GEO And AISEO?

GEO and AISEO are pretty closely related (and the acronyms are often used interchangeably), but before considering agencies, it’s important to understand what they actually are.

GEO refers to Generative Engine Optimization, which involves optimizing content in a way that makes it easier to be understood, trusted, and referenced (cited) by generative AI platforms like ChatGPT, Perplexity, Google’s AI Overviews, Copilot, and others.

GEO is very centered on large language models (LLMs) to focus on establishing placement in generative answers and citations, with or without the use of a search engine (like Google or Bing).

AISEO refers to Artificial Intelligence Search Engine Optimization, which is the broader umbrella and covers all AI-powered search experiences to improve search visibility, as well as using AI tools for things like data analysis and keyword research.

AISEO includes a focus on LLMs (like ChatGPT or Perplexity), but it also focuses on traditional search engine ranking and visibility (in search engines like Google or Bing, for example).

Why Do GEO And AISEO Matter So Much?

GEO and AISEO determine whether or not your brand shows up in AI-powered search environments or generated answers.

These days, people are asking questions within AI tools (like ChatGPT), and the answers being generated typically rely on only a few trusted sources; you want your brand to be one of them. If your brand or content isn’t being selected as a source, it essentially becomes invisible within these environments, even if it’s ranking well in search engines like Google.

But search engines also rely heavily on AI to rank and present content. Keywords are still important, of course, but so is user intent, which is interpreted by LLMs. And while AI continues to reduce clicks in favor of providing immediate answers, AISEO preserves your brand’s exposure higher in the funnel, particularly in the AI Overviews, which are displayed at the very top of any search result.

How I Chose These Agencies

Every entry on this list was evaluated against five criteria:

1. Articulated GEO methodology — does the agency have a clearly defined approach to AI visibility, not just SEO with “AI” sprinkled on top?
2. Track record and client transparency — published case studies, named clients, or verifiable results.
3. Channel coverage — work spans on-site SEO, off-site signals (Reddit, YouTube, communities), and AI citation building.
4. Measurement infrastructure — tools or processes to actually track AI citations, share of voice, and sentiment.
5. Team experience — leadership with depth in SEO, content, and the practical realities of how LLMs retrieve and cite information.

This isn’t a “top 50” list. It’s six agencies, each chosen because they represent a meaningfully different approach to GEO/AISEO.

Below are the best GEO/AISEO agencies right now

ScaleVisible

A digital marketing agency that focuses on helping brands grow their organic visibility and discovery in AI-driven search, ScaleVisible’s strategy focuses on gaining recognition and citations from AI assistants and answer engines, with campaigns being leveraged across social platforms like YouTube, TikTok, and Reddit. 

Taking a “bullets before cannonballs” approach, ScaleVisible begins by testing various strategies to see what works best for a brand before refining and scaling only those that show the best ROI. 

This means that every brand essentially has its own bespoke playbook. Success isn’t just about understanding the GEO/AISEO landscape; it’s about strategy, testing, and execution.

ScaleVisible taps heavily into UGC (user-generated content) to build brand references across websites and social media. This essentially “teaches” AI how to perceive a brand and helps that brand to not only rank in traditional search engine results, but AI-driven search interfaces.

ScaleVisible Pros

• AI-first strategy that emphasizes visibility in LLM outputs and generative search.
• UGC and multi-channel placements across websites, video platforms (like YouTube or TikTok), and communities like Reddit to improve brand visibility right where audiences are talking about and engaging with topics.
• Experiment-driven approach that reduces risk and improves ROI.
• Helps to shape brand perception and sentiment for AI answers and brand trust signals.
• The team behind ScaleVisible has more than 20 years of experience successfully navigating the internet’s ever-changing digital landscape, including Google’s algorithms and the rise of AI-driven search.

ScaleVisible Cons

• As of this writing, ScaleVisible doesn’t share any public case studies or named clients. (That said, companies who grow through word of mouth don’t need to; their clients advertise for them.)
• Since pricing is bespoke for each brand and the number of hours contracted monthly, it isn’t available on the website.

Foundation

Foundation Marketing is a digital growth agency that primarily works with B2B, Saas, and other industries that are considered “boring” (their word, not mine). Content marketing is a main focus at Foundation, and that includes strategy, creation, and distribution.

They emphasize delivering long-term organic value and, like ScaleVisible, they utilize many platforms that include websites (for editorial content), social media, Reddit, and even newsletters.

Foundation’s focus still remains on SEO-led content, and while they have begun positioning toward AI-driven visibility and optimization strategies, those are nested within their existing content and distribution services.

Overall, Foundation focuses more on strategy vs execution compared to agencies like ScaleVisible which is end to end strategy and execution in third party networks

Foundation Pros

• Will audit old content to optimize for search and conversion, alongside any new content strategy they arrange.
• Provides multi-channel distribution and backlink acquisition for long-term growth.
• Specializes in B2B and SaaS, along with other niches (like manufacturing) that aren’t typically thought of as exciting.
• Foundation’s been around for 11 years (as of this writing), and the agency has a pretty decent track record of experience.

Foundation Cons

• They claim a lot of results and do share a few case studies, but the clients are not named and no screenshots of results are displayed, even redacted.
• More expensive than services like ScaleVisible.
• Has GEO/AISEO awareness, but the primary focus still relies on traditional SEO and organic traffic, as of this writing.
• Heavier on strategy than execution
• Like ScaleVisible, pricing is entirely bespoke.

Coalition Technologies

A full-service digital marketing and web design agency, Coalition Technologies offers a broad range of services that include GEO/AISEO but go far beyond visibility in LLMs. 

In fact, Coalition Technologies does a little bit of everything: SEO, PPC, web design, social media and email marketing, and even custom app development.

For brands that need more in terms of support and strategy, or that are seeking a cohesive growth strategy, Coalition might be a great fit as a one-stop shop for everything. 

Coalition Pros

• AISEO services are aimed at optimizing for generative search and visibility in LLMs. 
• Emphasizes analytics and custom reporting for brands that need measurable ROI.
• Broad range of services beyond GEO/AISEO (or even “basic” SEO, for that matter).
• Flexible contracts, which include a month-to-month.
• Provides many case studies across various services, with named clients and detailed results.

Coalition Cons

• Provides many services, but there’s something to be said for doing fewer things better. 
• Those seeking very deep niche expertise may find the full-service approach less tailored compared to specialized companies.
• Pricing at Coalition is bespoke, but there is an estimate calculator available.

Passionfruit 

As an “AI native” agency, Passionfruit is focused on SEO, GEO, and AI-driven ad optimization. In fact, the core team comprises content and marketing professionals, along with AI engineers. 

For GEO specifically, Passionfruit reverse-engineers how AI thinks, targeting natural language patterns often missed by competitors as part of its keyword strategy. 

One thing that sets this agency apart from others in this list is Passionfruit Labs, which is a GEO tool that provides page-level citation tracking, content insights and action plans, revenue tracking, and more. If you’d prefer to take GEO/AISEO strategy into your own hands, the dashboard tracks all the important things necessary to make the best decisions, including brand mentions and sentiment analysis, revenue attribution, and even competitor benchmarking, similar to what you’d get with Peec.ai.

Passionfruit Pros

• Offers end-to-end GEO services to help brands gain visibility in AI-driven results (AI search engines and overviews).
• Has published detailed case studies with named clients and metrics.
• Offers a software platform (Passionfruit Labs) for those who prefer to manage their own GEO.

Passionfruit Cons

• Primarily geared toward enterprise-level businesses.
• Has only been around since 2023, so there’s a limited “history” compared to other GEO/AISEO agencies in this list.

Victorious

Having worked with more than 600 brands, Victorious is one of the most well-known digital marketing agencies out there, offering a full suite of core SEO services. With the rise of AI-driven search, however, they’ve added AEO (Answer Engine Optimization) to their repertoire, integrating SEO fundamentals with AI-search optimization as an extension of what they already do well.

While Victorious offers AEO, SEO, and content marketing services, they also provide managed WordPress hosting for brands that don’t want to run their own sites (or deal with the headaches that can cause). That includes content strategy and creation, alongside SEO and AEO.

If your brand prefers a hands-off approach to digital marketing while maximizing its presence in AI-driven search, Victorious can get it done.

Victorious Pros

• Vast and proven experience with SEO and (now) AEO that’s aimed at voice search and AI-generated answers.
• Customized strategy to meet measurable goals, structured project management, and clear reporting.
• Focus on ROI more than just metrics (like rankings or traffic). 

Victorious Cons

• Recommends a minimum $5,000 per month budget (with 12-month commitments), with some projects ranging higher; this isn’t necessarily geared toward smaller brands or start-ups.
• For brands that have omnichannel needs, Victorious doesn’t offer PPC, CRO, or paid media management.

WebFX

Providing end-to-end digital marketing services that include SEO and now AISEO, WebFX has been in the business the longest of any agency on this list (30 years). Although they got their start in 1995 as WebpageFX, they’ve expanded far beyond web design into broader spaces as a full-stack agency.

WebFX’s optimization strategy, called OmniSEO, encompasses everything from search engines, AI assistants, voice search, and even social media. This methodology combines tried-and-true SEO fundamentals with platform-specific strategies that improve brand visibility in the spaces where users (or potential customers) are seeking information.

WebFX Pros

• Long track record in the business and a reputation built on results.
• Provides everything from web design and UX to SEM and PPC, SEO, GEO, CRO, proprietary analytics, CRM integrations, and more, if you prefer one agency that handles everything.
• Offers revenue-focused reporting that gives brands more insight into ROI beyond traffic metrics.

WebFX Cons

• Can be expensive; GEO services start at $3000 per month, and pricing is entirely custom based on strategy and deliverables.
• Has perhaps the broadest focus of any agency on this list, so you might not get the deepest niche GEO/AISEO expertise compared to smaller boutique agencies.

Side-by-Side Agency Comparisons

Most “best of” articles stop at the individual profiles. Here’s where it gets useful — direct comparisons for the most common decisions:

ScaleVisible vs Passionfruit (AI-First Specialists)

Both are GEO-native, but they solve different problems. ScaleVisible wins if you want UGC, Reddit, and multi-platform community visibility — the off-site signals that increasingly drive AI citations. Passionfruit wins if you want a proprietary tracking dashboard and the option to bring GEO in-house via software.

Foundation vs ScaleVisible (Content + Multi-Channel Approaches)

These two are the closest direct comparison on this list — both build visibility through content and multi-channel distribution rather than pure technical optimization. The difference is where they start.

Foundation is content-first with SEO as the spine. They’ve spent ~11 years building editorial muscle in B2B and SaaS, and their GEO work nests inside that existing content engine. The strength: deep niche expertise in “boring” industries most agencies won’t touch, and a documented track record of ranking and traffic growth. The trade-off: GEO is layered onto traditional SEO rather than built from scratch around how LLMs actually retrieve and cite content.

ScaleVisible is AI-first with content and UGC as the execution layer. They start from “how do we get this brand cited by ChatGPT and Perplexity” and work backward into placements across Reddit, YouTube, TikTok, and editorial sites. The strength: native fluency in the off-site signals that increasingly drive AI citations, plus an experiment-driven playbook that adapts per brand. The trade-off: less public proof (no named clients on the site) and less industry-specific specialization than Foundation.

Pick Foundation if: you’re a B2B or SaaS brand that needs sustainable content authority and GEO, and you value a longer track record over AI-native methodology.

Pick ScaleVisible if: you want AI citations and community-driven visibility as the primary outcome, and you’re comfortable with bespoke playbooks over case-study-heavy pitches.

Coalition vs WebFX (Full-Service Agencies)

Both offer GEO inside a broader marketing engagement. Coalition Technologies is more flexible (month-to-month available, lower starting commitment) and better for mid-sized brands. WebFX has more scale, longer tenure, and proprietary technology, making it stronger for enterprise rollouts.

Foundation vs Victorious (Long-Term Authority Builders)

Both build sustainable visibility through content and SEO depth. Foundation is content-first, with strong B2B/SaaS specialization and multi-channel distribution. Victorious is search-first, with broader brand experience and a more structured engagement model — but a higher minimum commitment.

When to Pick a Specialist vs a Full-Service Agency

Pick a specialist (Passionfruit, ScaleVisible, Foundation, Victorious) when GEO/AISEO is your primary problem and you have other agencies handling adjacent work. Pick full-service (Coalition, WebFX) when you want fewer vendor relationships and a more integrated growth program.

What To Consider Before Hiring A GEO Or AISEO Agency

Before signing a contract with any agency specializing in AI-driven search optimization, there are several things to look for (or ask). 

• Ask: What platforms they optimize for (such as Google AI Overviews, ChatGPT, Perplexity, and others), and how their work differs from standard SEO.
• Look for: concrete examples of improved visibility, citations, and changes in AI-generated mentions, and if those are not available as public case studies on the agency’s website, ask to see examples. Even if client names must be redacted for privacy, there should be a digital trail of proof beyond promises.
• Ask: How the agency measures success and what metrics or reporting you’ll receive. This might mean brand mentions, sentiment shifts, citation frequency, or referral traffic, for example.
• Look for: AI optimization that builds upon technical SEO, content quality, and authority, because these still matter. (As I mentioned earlier, SEO is not dead!)
• Ask: Whether their content strategy relies on your brand’s site alone, or if it will involve third-party platforms like other websites, social media, communities/forums, or video platforms. (The answer should be “yes;” off-site visibility matters.)
• Look for: scope clarity as far as strategy, execution, content creation, placements, reporting, iteration, and timelines are concerned. Most deliverables (and pricing) are customized and can vary widely based on the brand, so make sure you know what is (or isn’t) included and what it will cost.
• Ask: How messaging is controlled if they use UGC (user-generated content, like video reviews), communities (like Reddit), or influencer-style placements. You should understand exactly where your brand will appear and how tone, compliance, and accuracy are handled.
• Look for: a focus on long-term success vs. short-term “quick wins.” Be wary of any agency promising instant dominance in AI overviews; just like SEO, GEO, and AISEO is a long game that focuses on authority building, not hacks (or shortcuts).

Hiring a GEO or AISEO agency is about finding a partner who understands how AI discovery actually works, can offer complete transparency into their experience and approach, and respects the fundamentals of brand authority, content, and search. 

How is GEO different from AEO?

AEO (Answer Engine Optimization) targets direct-answer formats: featured snippets, voice search responses, “People Also Ask” boxes, and short Q&A extraction. GEO targets citations and references inside longer AI-generated answers and summaries. AEO content tends toward concise question-answer pairs; GEO content tends toward comprehensive, citation-worthy depth. Most modern agencies offer both.

How much does a GEO/AISEO agency cost?

Pricing varies widely based on scope, but typical ranges in 2026:

• Entry-level retainers: ~$3,000–$5,000/month (full-service agencies adding GEO)
• Mid-market specialist retainers: ~$5,000–$10,000/month
• Enterprise programs: $10,000+/month, often with 6–12 month commitments

Most agencies don’t publish pricing because deliverables vary so much. Always ask for scope clarity in writing.

Which AI platforms should my GEO strategy target?

The big four: ChatGPT, Perplexity, Google Gemini (and AI Overviews), and Claude. Microsoft Copilot is a fifth worth tracking. Each weights signals slightly differently, but content and authority strategies that win in one tend to compound across all of them.

Is SEO dead because of AI?

No. SEO is evolving, not dying. Strong Google rankings remain one of the most reliable predictors of LLM citations — AI systems heavily weight content that already performs well in traditional search. Skipping SEO fundamentals to “do GEO” is a mistake. The best agencies treat SEO and GEO as additive, not competing.

How long does GEO take to show results?

Expect 3–6 months for early signals (first AI citations appearing, share-of-voice movement) and 6–12 months for meaningful, durable visibility. Agencies promising instant AI Overview dominance are overselling. GEO is an authority-building game, not a hack-driven one.

Should I hire a GEO specialist or a full-service agency?

Hire a specialist (Passionfruit, ScaleVisible, Foundation, or Victorious) when GEO/AISEO is your primary problem and you have other partners handling adjacent work. Hire full-service (Coalition or WebFX) when you want fewer vendor relationships and an integrated growth program covering SEO, paid, content, and GEO together.

What metrics should a GEO agency report on?

Beyond standard SEO metrics, expect: AI citation frequency (how often your brand is referenced in LLM answers), share of voice across LLMs (your brand vs. competitors in AI results), sentiment analysis (how AI tools characterize your brand), AI referral traffic (visitors arriving from ChatGPT, Perplexity, etc.), and brand mention growth across third-party platforms. If an agency only reports keyword rankings, they’re not really doing GEO.

Can I do GEO myself instead of hiring an agency?

Yes, especially if you already have strong SEO and content foundations. Tools like Passionfruit Labs, Peec.ai, and similar platforms make tracking and execution feasible in-house. Agencies are most valuable when you need scale (volume of content and placements), specialized expertise (technical entity optimization, RAG-aware structuring), or off-site channels (Reddit, community, YouTube) you can’t credibly run internally.

Final Word on the Best GEO Agencies

Artificial intelligence has changed the way people discover brands online, and while there will probably always be a place for traditional search engine optimization, both GEO and AISEO are a necessity in the modern search landscape. 

The agencies I listed above stand out because they have a proven track record of building sustainable visibility across search engines and emerging generative platforms. Effective strategies don’t come from hype, but from teams that evolve and adapt alongside search technology, while staying grounded in what actually drives trust, authority, relevance, and long-term growth.
