Key Takeaways

• The five agencies here suit different company profiles: enterprise brands fit iPullRank's scale and named client roster, B2B SaaS companies fit Omniscient Digital's existing content practice, and a team that wants to run tracking and execution itself fits AIclicks better than hiring any of the four service agencies.

• Pricing for agency engagements is rarely published; most work on custom quotes or retainers scoped to platform coverage and competitive complexity, unlike self-serve software with listed monthly tiers.

• Several of these agencies grew out of traditional SEO or content marketing practices and added AI-search work as a newer service line, rather than being built exclusively around ChatGPT from day one.

• A software platform that tracks and lets a team act on its own ChatGPT visibility is a different kind of solution than a full-service agency handling strategy, content, and execution on a client's behalf, worth knowing which one a team actually needs before hiring.

What Makes a ChatGPT SEO Agency Worth Hiring

• It treats ChatGPT visibility as part of a broader content and technical strategy rather than a one-off audit, since citations build from the same groundwork as traditional organic rankings.

• It backs claims with named case studies and specific metrics rather than vague promises of "AI visibility," so a prospect can judge a real track record before signing a retainer.

• Its team includes people with a demonstrated background in search or content strategy specifically, not a generalist marketing shop bolting AI search onto an unrelated service list.

Quick Comparison

1. AIclicks: Best for Running ChatGPT Visibility Tracking In-House Instead of Hiring It Out

AIclicks is a self-serve AI visibility platform, not a service agency. It tracks how often and where a brand gets cited across 10+ AI platforms including ChatGPT, Gemini, Perplexity, Google AI Overviews, and Copilot, then gives a team the tools to close visibility gaps itself: Prompt Analytics for tracking, Sources and Competitor Discovery for citation intelligence, AI Traffic for GA4-connected referral tracking, and an Actions suite (Writer 2.0, Get Mentioned, Engage Online) for acting on what the tracking finds. A team gets much of the same visibility and execution capability the agencies below sell as a service, but runs it directly rather than handing it to outside consultants.

Key features:

• Prompt Analytics tracking ChatGPT visibility alongside Gemini, Perplexity, AI Overviews, and Copilot in one dashboard

• Sources and Competitor Discovery showing which pages get cited in ChatGPT answers and which competitors get cited instead

• AI Traffic connecting to GA4 to measure actual referral traffic from ChatGPT and other AI engines

• Actions suite (Writer 2.0, Get Mentioned, Engage Online) turning tracked gaps into published content and outreach directly

Pros:

• Published, self-serve pricing rather than a custom quote gated behind a sales call

• A team can see and act on its own ChatGPT visibility without waiting on an agency's reporting cycle

• 3-day free trial with no credit card required on Starter and Pro

Cons:

• It's software rather than a full-service agency, a team without in-house capacity to act on what the tracking finds will still need to pair it with an agency or hire for content and outreach execution

• Enterprise-scale multi-brand tracking sits behind a custom Enterprise plan rather than the published Business tier

G2 rating: 4.9/5

Pricing: Starter $59/mo | Pro $189/mo | Business $499/mo | Enterprise custom | 3-day free trial 

Verdict: For a team that wants to see its own ChatGPT visibility and act on it directly rather than hand the whole job to an outside team, AIclicks gives the tracking and execution tools to do that in-house, though it doesn't replace an agency's hands-on strategy and execution when that capacity doesn't exist internally.

2. iPullRank: Best for Enterprise GEO Strategy Backed by a Recognized Search Voice

iPullRank is a boutique agency founded by Mike King, named 2025 Search Engine Land Search Marketer of the Year on its own site. Its core AI-search discipline is Generative Engine Optimization, covering brand visibility across ChatGPT, AI Overviews, and AI Mode under what it calls Relevance Engineering, paired with a content-focused discipline it calls Resonance Design. The team runs to roughly 35-40 staff, and homepage client logos include Target, Adidas, American Express, and The Wall Street Journal, though named case-study detail is withheld under client NDAs.

Key features:

• Relevance Engineering, technical and structural groundwork for visibility across ChatGPT, AI Overviews, and AI Mode

• Resonance Design, a content discipline built to complement the technical Relevance Engineering work

• Omnimedia Strategy extending visibility work across press, forums, reviews, video, and social

• A three-stage engagement model: Assess, Prioritize, Activate

Pros:

• Led by Mike King, named 2025 Search Engine Land Search Marketer of the Year on the agency's own site

• Anonymized case-study figures cited include $2.4B in incremental revenue for a banking client and 130% traffic recovery for an automotive publisher

• Client roster includes recognizable enterprise names like Target, Adidas, and American Express shown on the homepage

Cons:

• No pricing is published anywhere on the site; every engagement starts with a consultation call rather than a listed rate

• Named case-study detail is withheld due to client NDAs, so the cited results can't be traced back to a specific, named campaign

Pricing: Custom, consultation-based

Verdict: For an enterprise brand that wants GEO strategy from a team with a well-known name in search specifically, iPullRank's Relevance Engineering approach is built for that scale, though a prospect should expect a sales conversation rather than a public price to start.

3. Previsible: Best for Multi-Platform AI Discovery Led by Former Search-Analytics Executives

Previsible’s core Generative Engine Optimization service line covers visibility across ChatGPT, Claude, Gemini, and other AI-recommendation surfaces including Copilot, Amazon Alexa, and Amazon Rufus, positioning ChatGPT as one of several tracked platforms rather than an exclusive focus. The agency has grown to roughly 70 team members across 10 countries, following its 2025 acquisitions of Internet Marketing Ninjas and Improove US.

Key features:

• GEO Strategy service covering visibility, citation, and recommendation tracking across ChatGPT, Claude, Gemini, and other AI surfaces

• Technical SEO and Authority Building service lines supporting the GEO work with foundational site and trust signals

• Named case studies published on-site with specific metrics for clients including Atlassian, Etsy, and Coursera

• Recent acquisitions of Internet Marketing Ninjas and Improove US expanding its technical and search-quality bench

Pros:

• Founded specifically around AI-era search discovery, led by executives with a search-analytics background at Searchmetrics

• Reports 113% revenue growth in 2025 and support for 100 brands that year, published on its own site

• Named, metric-backed case studies rather than anonymized figures

Cons:

• No pricing is published anywhere on the site; the GEO Strategy page states only that engagement pricing depends on platform scope and competitive complexity

Pricing: Custom, consultation-based

Verdict: For a brand that wants AI-discovery strategy from a team built around this category from the start, rather than an SEO shop retrofitting AI-search onto existing services, Previsible's leadership background and 2025 growth numbers make a reasonable case, as long as ChatGPT-specific work is understood as part of a broader multi-platform strategy rather than the sole focus.

4. Graphite: Best for AEO Backed by a Dedicated Data Research Team

Graphite runs Answer Engine Optimization as a named service line alongside traditional SEO and performance marketing. It tracks ChatGPT alongside Perplexity, Gemini, and Google AI Overviews, built on named service components including Prompt Research and Citation Tracking & Analytics.

Key features:

• AEO service line including ChatGPT, Perplexity, Gemini, and Google AI Overviews specifically as target platforms

• Prompt Research and Citation-Ready Content components identifying and targeting the prompts that drive citations

• Citation Tracking & Analytics measuring whether the work is actually landing brand mentions inside AI answers

• Led by a Chief AI Officer and a PhD data specialist rather than a generalist marketing team alone

Pros:

• Case studies published on-site cite specific, sizable results, including a 936% search revenue increase for Fourthwall and organic traffic growing from 74K to 3.8M monthly for BetterUp

• AEO is treated as a co-equal service line alongside SEO rather than a bolted-on add-on

• Leadership includes dedicated AI and data specialists alongside generalist strategists

Cons:

• No pricing is published anywhere on the site

Pricing: Custom, consultation-based

Verdict: For a brand that wants AEO work backed by a team with dedicated AI and data expertise, Graphite's named leadership and published case-study results make a reasonable case, though a prospect will need a direct conversation to get any sense of cost.

5. Omniscient Digital: Best for B2B SaaS Brands Adding GEO to an Existing SEO Engine

Omniscient Digital is a B2B-focused SEO and content agency, founded by David Ly Khim, Alex Birkett, and Allie Konchar, all with backgrounds at HubSpot. Generative Engine Optimization is one of nine listed services, it covers ChatGPT, Claude, Gemini, and Perplexity under four principles: product source-worthy content, brand and author entity optimization, citation engineering, and technical optimization.

Key features:

• GEO service applying four named principles: product source-worthy content, brand and author entity optimization, citation engineering, and technical optimization

• GEO offered alongside eight other established services including Technical SEO, Content Production, Link Building, and Digital PR

• Case studies published on-site include Smartling's $3.7M pipeline and Jasper's 810% sessions growth

• Roughly 30-person team distributed across nine countries

Pros:

• Founding team has direct B2B SaaS growth backgrounds at HubSpot, relevant to the B2B brands it targets

• Published starting price gives a concrete budget reference most agencies in this list don't offer

• GEO is built on top of an already-established SEO and content practice rather than a standalone new offering

Cons:

• Only 2 of the 14 published case studies foreground AI-visibility metrics specifically; most published results are traditional organic-traffic and pipeline numbers

Pricing: Custom, consultation-based

Verdict: For a B2B SaaS brand that already runs SEO and content through an agency and wants to add GEO without starting over with a new specialist shop, Omniscient Digital's four-principle GEO service sits naturally on top of its established B2B practice, with published case studies still leaning traditional-SEO-heavy for now.

How to Choose a ChatGPT SEO Agency

• Decide whether the job needs a software platform a team runs itself or a full-service agency handling strategy and execution, since AIclicks and the four service agencies here solve different problems.

• Ask for platform-specific proof, not just a general AI-search pitch, since ChatGPT, Gemini, and Perplexity behave differently and a strong result on one doesn't guarantee the same on another.

• Treat published pricing as the exception rather than the rule in this space; most agencies scope cost to platform coverage and competitive complexity rather than listing a flat rate, so get a quote before assuming a budget fits.

Frequently Asked Questions

Is ChatGPT SEO the same as traditional SEO?

Not exactly. Traditional SEO targets rankings on a search results page, while ChatGPT visibility depends on whether a brand gets cited or recommended inside a generated answer. The two overlap heavily since strong technical SEO and authoritative content support both, and none of the agencies here treat them as fully separate disciplines.

Do these agencies only work on ChatGPT, or other AI platforms too?

All four service agencies in this list work across multiple AI platforms. ChatGPT, Gemini, Perplexity, Claude, and AI Overviews are commonly tracked together, since the same underlying content and technical work tends to support visibility across more than one engine at once.

How much does a ChatGPT SEO or GEO engagement typically cost?

Most of these agencies don't publish pricing and instead scope cost through a consultation based on platform coverage and competitive complexity. Omniscient Digital is the exception, stating full-service engagements start at $10,000 a month.

Can a team handle ChatGPT visibility without hiring an agency?

Yes, with the right tooling. A platform like AIclicks lets a team track its own ChatGPT citations and competitor visibility directly and act on gaps it finds, a different path than handing the entire strategy to an outside agency.

How is success measured in ChatGPT SEO work?

Citation frequency, share of voice against named competitors, and referral traffic from AI platforms come up most often across these agencies' own case studies, alongside the traditional organic traffic and pipeline numbers most of them still report.
