Best AI SEO/GEO Agencies in 2026

Key Takeaways:

• There is no single best AI SEO agency – only the best pick, based on your industry, goals, and budget.

• ZeroClick Labs is the only pure AI-search specialist on the list – and the one with the lowest entry point @$1,500/mo.

• Thrive and Forthea are strong fits if you want AI optimization folded into a full-service program.

• Grow and Convert suits organizations that measure content by pipeline.

• Mint Position delivers editorial content to fintech/SaaS companies.

Executive Summary: We compared five agencies offering top-rated answer engine optimization services: ZeroClick Labs, Grow and Convert, Mint Position, Thrive, and Forthea. Each entry has its strengths and weaknesses, emphasizing the need to match the agency to the job, not the other way around.

Your buyers ask ChatGPT for recommendations, read Google’s AI Overview summaries instead of your pages, and get Perplexity to draft vendor shortlists. Indeed, the search has changed forever:

The result is no longer the answer. The AI’s response is.

Getting into that response has become THE objective for any brand even remotely relying on the Internet to generate business – which, let’s face it, is the vast majority of them.

Getting into that response is also a different beast from traditional SEO.

That’s why a growing segment of SEO teams now offer “entry” under labels like Generative Engine Optimization (GEO) or Answer Engine Optimization (AEO).

This guide provides a realistic comparison of 5 best AI optimization SEO agencies in 2026 including ZeroClick Labs judged on the same criteria as other entries.

What is the best AI SEO agency?

There is no single, de facto top AI SEO agency here – only the best fit for your objectives, budget, and industry. For this reason, our roundup is a realistic comparison, not a leaderboard. 

As such, it should be interpreted as a showcase of the service providers’ capabilities (currently and in the face of upcoming AI-marketing trends), and a guide to matching those capabilities to your unique operational requirements.

ZeroClick Labs: Research-led GEO & AEO specialist

ZeroClick Labs is a generative engine optimization agency founded in 2025 by Jordan Parkes, a digital marketing strategist with 15+ years of experience, over which time he and his team served 200+ clients across the U.S., Europe, Asia, and Australia. Built as an AI-first SEO agency, ZeroClick Labs focuses on one thing only: making brands stand out in AI search. 

Jordan Parkes’ background combines technical SEO, performance marketing, and AI-search strategy, giving ZeroClick Labs a founder-led approach to an emerging discipline. He also contributes to the wider conversation around AI visibility, GEO, and search measurement, with expert commentary and features appearing in industry publications such as CMSWire and Digiday. 

ZeroClick Labs’ AI SEO specialization is deliberately narrow, covering Google AI Overviews and AI Mode, Gemini, ChatGPT, and Perplexity, plus voice and visual search, paid AI advertising, and LLM-optimized web design and development.

The team’s approach to generative engine optimization is data-driven and performance-first: ZeroClick Labs does in-depth audits of past marketing strategies and KPIs to identify the visibility gaps that hold the brand back. Then, it builds toward genuine, durable authority and measurable, repeatable results rather than short-lived spikes.

ZeroClick Labs also publishes original AI search research through The Laboratory, testing how generative engines select sources, measure visibility, and surface brands. This research helps the agency adapt its strategies as AI search changes, rather than relying solely on traditional SEO assumptions.

Every aspect of optimization is handled entirely by an in-house team, from technical audits to citation-optimized content production and even influencer partnerships. Client involvement is minimal, boiling down to approvals, strategic decisions, and context, but the day-to-day grind is handled completely independently.

The ZeroClick Labs pricing features three monthly retainers at $1,500, $3,500, and $7,500, scaling from foundational authority and technical readiness to active content, outreach, and brand narrative control. At $1,500/mo, it’s the lowest entry point into AI visibility work of any agency here.

ZeroClick Labs points to published case studies for proof, and the results speak for themselves: a #1 average position across LLMs and +78% AIO visits for an FDA-registered tool-maker, +383% AIO clicks and presence in 83% of tracked prompts for a SaaS company, and 101% traffic and a 5× conversion increase in ChatGPT for a regional remodeler.

Grow and Convert: for content that answers to revenue

Grow and Convert was founded in 2015 by Devesh Khanal and Benji Hyam. As their name implies, they are one of the more established generative engine optimization agencies around, whose approach heavily revolves around conversion-focused SEO and GEO content.

In addition to SEO/GEO-centered content, G&C delivers AI-citation outreach and link building, technical SEO, and paid search (PPC) – targeting ChatGPT, Perplexity, and AI Overviews alongside traditional rankings.

Their work relies on two signature methods: “Pain Point SEO,” which targets bottom-of-funnel, buyer-ready topics, and “Prioritized GEO,” which treats that same content as the source material for AI citations.

G&C’s standout is its reputation for outcomes over output. Its content is tied to pipeline and revenue rather than pageviews, enabling you to trace content-related expenditures back to leads, demos, and closed revenue, and defend the budget in a pipeline report instead of a traffic chart.

Pricing is where Grow and Convert gets obscure. Their official page has no published rates, but their Clutch profile lists a $10,000+ minimum project size – easily the highest entry point on our list and clearly aimed toward enterprise clients.

The agency’s proof also leans on a small but strong set of self-reported outcomes, with a flagship case touting a client’s booked revenue growth from content by 362% in 18 months and content growth from 5% to 25% of the revenue, definitely nothing to scoff at.

Mint Position: Newsroom rigor, tuned for AI visibility

Mint Position was founded in 2020 by Justin Calderón, a former BBC, CNN, Newsweek, and The Guardian journalist. It’s a small, specialized content marketing agency focused on the fintech and B2B SaaS sectors first, and proptech, logistics, ecommerce, and tech recruitment second (among others).

Services-wise, Mint Position offers editorial-grade SEO/GEO content production, guest posting, GEO audit, and e-book production, with social media management, online ads, and digital PR as supporting add-ons.

Mint’s method is documented and structured, reflecting the founder’s journalistic sensibilities: articles are built from expert interviews, supported by heavy buyer and keyword research, an SEO/GEO audit, and structured for AI citation across ChatGPT, Gemini, Claude, and AIOs.

Both the services and method tie in neatly into what is Mint Position’s key standout: editorial quality. Being heavily research-driven, its articles read like reporting rather than marketing, which goes a long way toward building the kind of authority AI engines reward.

Mint’s pricing plans, while transparent, are quite steep for what they offer. Core service ($2,600/mo, 3 months min) doesn’t include backlink building (+$1,750/mo), social media management (+$1,000/mo), or graphic design (undisclosed), meaning that a well-rounded AI visibility plan (not a full-coverage plan) would run you approximately $5,350+ a month.

As is the pattern by now, Mint’s proof also relies on self-reported numbers, with a star example being an increase in one B2B real-estate-finance client’s LLM visibility from 12% to 72% over six months, which is an honest result window that the agency publishes upfront.

Thrive Internet Marketing Agency: The full-stack veteran

Thrive Internet Marketing Agency was founded in 2005 and is headquartered in Arlington, TX, with a presence in over 25 US cities. It is one of the largest and most established agencies on this list – and also the one with the most comprehensive suite of optimization services.

Thrive runs pretty much the entire digital marketing stack: from traditional and AI SEO to PPC, social, web design, content, and CRO. They even offer SEO-optimized video production, attesting to the sheer breadth of their coverage.

It is also one of two entries on this list that delivers human-driven, AI-powered SEO agency services. Thrive GEO efforts rely on a proprietary AI visibility suite (“ThriveAI”), pairing machine precision, speed, and efficiency with human creativity and accountability.

Taking everything into account, Thrive’s obvious standouts are scale and staying power – they’ve been in business for 20+ years, made the Inc. 5000 seven years in a row, and boast a team of 160+, signaling the capacity to run massive multi-channel programs on its own.

Thrive’s pricing is by request only, with the published SEO marketing scope ranging from $500 to $10,000+, which is too big a gap to serve anything but illustrative purposes. They do narrow it a bit in the FAQ though (local SEO $500-$1,500/mo, small-business SEO $500-$5,000/mo, consulting $150-$300/h), but there’s still no mention of AI SEO numbers.

For AI-search proof specifically, Thrive publishes its own case studies, and the numbers are striking to put it mildly: +2,658% lift in AIO citations for a primary-care client and +876% ChatGPT engaged sessions for a retailer.

Forthea: A full stack of services – and trophies

Forthea was founded in 2006, putting it in a similar bracket as Thrive in terms of staying power. As a data-driven digital marketing agency, Forthea has catered to over 500 brands and boasts the strongest traditional paid marketing and SEO pedigree in this comparison.

Forthea’s services cover paid media (search, display, social), SEO, marketing analytics, web design and development, and CRO. However, unlike other entries on this list, Forthea folds AEO and GEO under SEO, rather than offering them as standalone services.

Their process is distinguished by analytical depth: Forthea staffs Ph.D. data scientists, so their strategies are backed with rigorous measurements. Since even the best AI visibility tracking tools are still catching up to how buyers search, that level of certainty is the real edge.

Still, the agency’s biggest standout is credentials: Forthea is a Google Premier Partner (2025) and a winner of US Search Awards 2024 and US Agency Awards 2025, with multiple Inc. 5000 listings.

Naturally, the pedigree and certainty come at a price. Although Forthea doesn’t disclose rates, instead working from custom proposals with “transparent billing” (the irony), its Clutch profile lists a $5,000+ minimum project size, positioning it as a mid-market to enterprise pick.

As proof of their outcomes, the agency publishes case studies with self-reported numbers showcasing why they are considered one of the top AI SEO agencies in the US: AIO appearance leap from 1 to 61 with a 59% lift in call volume for a property-restoration franchise and 300% increase in AI answers with a 231% jump in demo requests for a GRC software provider.
