How We Selected These Agencies

No agency paid to appear on this list. We evaluated each one across six areas:

  • Demonstrated GEO and AI visibility capability
  • Technical SEO depth: crawlability, indexing, schema and site architecture
  • Content and entity strategy: evidence of information gain and topical authority
  • Industry-specific experience in ecommerce, SaaS, B2B or enterprise
  • Reporting that accounts for AI visibility, not just rank positions
  • Client outcomes with real commercial results attached

If an agency couldn’t show meaningful work in at least four of those areas, it didn’t make the cut.

Top 10 AI SEO Agencies 2026

1. eComOne

Location: Lincoln, United Kingdom

Overview

eComOne is a specialist ecommerce SEO agency with over 14 years of experience helping online retailers grow revenue through search. We were founded by Richard Hill, who scaled his own ecommerce business to multi-million pound turnover before building the agency. That background matters: we understand ecommerce commercially, not just technically.

We hold Google Premier Partner status and have been recognised with awards including 2024 Best eCommerce Team and a Sunday Times Top 100 Places to Work listing.

On the AI SEO side, we’ve moved deliberately. Rather than rebranding existing services under an AI banner, we’ve integrated GEO and LLM visibility work into how we approach content strategy, entity building and technical implementation. We treat AI search as an extension of good SEO practice, because that’s what it is.

Services

Ecommerce SEO, technical SEO, Shopify SEO, AI search optimisation, GEO, entity building, structured data, digital PR, content strategy, AI citation monitoring and SEO audits.

Best For

Ecommerce brands on Shopify, Magento, WooCommerce or custom platforms that want to grow organic revenue and build visibility across traditional search and AI platforms.

Industries

Ecommerce, retail, DTC brands, Shopify merchants.

“AI search visibility isn’t replacing SEO. It’s expanding it. Brands still need strong technical foundations, but now they also need content and entities that AI systems can understand, trust and reference.”

Keiran, Technical SEO Specialist at eComOne

2. iPullRank

Location: New York, USA

Overview

Founded by Mike King, iPullRank is one of the most technically rigorous SEO agencies operating today. The team has built a reputation for solving complex crawlability, indexation and JavaScript rendering problems at scale: precisely the kind of technical work that sits at the foundation of effective AI SEO.

iPullRank has also published original research into how language models process and retrieve content. Publishing original research is uncommon in this space; most agencies consume it rather than produce it.

Best For

Enterprise businesses with complex site architectures, large content libraries or significant technical SEO debt.

Industries

Location: Vancouver, Canada

Overview

Indexsy covers the full range of modern SEO disciplines: technical foundations, content strategy, link acquisition and GEO. For growth-stage businesses that need broad capability without the cost of multiple specialist agencies, that breadth is genuinely useful.

They’ve adapted quickly to the AI search shift and built GEO services into their offering early. What sets them apart is a practical, results-first approach that doesn’t get lost in theory.

Services

Full-service AI SEO, GEO, technical SEO, content strategy, programmatic SEO, AI citation building, entity optimisation and link building.

4. Spicy Margarita

Location: Remote (UK/EU focus)

Overview

Spicy Margarita has carved out a clear niche in B2B GEO, specifically helping SaaS companies improve their visibility in AI-generated answers. In a space where most agencies are still figuring out what GEO means, they’ve built a concrete playbook around SaaS buyer journeys and the kind of authoritative content that AI systems surface in response to commercial queries.

If you’re selling software and you want to appear in the AI-generated answer when a buyer asks ChatGPT what tool they should use, this is worth a conversation.

Services

GEO strategy, AI visibility tracking, B2B content optimisation, entity building, LLM citation monitoring and AI Overview optimisation.

Best For

SaaS businesses looking to improve visibility in ChatGPT, Perplexity and Google AI Overviews for high-intent B2B queries.

5. Onely

Location: Wrocław, Poland

Overview

Onely has earned a strong international reputation for solving crawl budget, indexation and rendering problems on very large websites. Their work often involves sites with millions of pages, and on that scale, poor technical SEO creates invisible barriers to both traditional rankings and AI-based visibility.

They’re rigorous, evidence-based and a genuine authority in technical SEO, speaking at major industry conferences and publishing original research. That combination of public contribution and client delivery is the marker of a team doing this properly.

Services

Technical SEO, crawl optimisation, JavaScript rendering, structured data, site architecture and AI readiness audits.

Best For

Large websites: publisher networks, large ecommerce sites and aggregators where technical SEO is the primary constraint on growth.

Industries

Publishing, large ecommerce, aggregators, news media.

6. NP Digital

Location: Global (headquartered in San Diego, USA)

Overview

NP Digital is one of the largest independent digital marketing agencies in the world. Offices across North America, Europe, Asia and Latin America give them data and testing capabilities that smaller agencies can’t match, and that scale has real advantages in AI search.

They’ve invested in AI SEO tooling and content systems that allow them to execute at volume. Their sweet spot is large-scale, multi-market campaigns. If you need a full-service agency with genuine AI SEO capability and a global footprint, they’re worth considering.

Services

SEO, GEO, AI content strategy, technical SEO, PPC, social, content marketing, conversion rate optimisation and AI visibility reporting.

Best For

Enterprise brands and larger businesses wanting a full-service digital marketing agency with AI SEO built in.

Industries

Enterprise, retail, B2C, media, financial services.

7. Skale

Location: London, United Kingdom

Overview

Skale is a London agency with a clear SaaS SEO focus. Their model is built around revenue-attributed outcomes, not traffic or ranking metrics. That distinction matters significantly in a B2B environment where the relationship between SEO activity and pipeline is often poorly measured.

As AI search has evolved, they’ve incorporated GEO and LLM visibility work into their SaaS growth playbooks, recognising that B2B buyers increasingly use AI assistants to research software purchases.

Services

SaaS SEO, GEO, AI search visibility, content strategy, link building, technical SEO and revenue attribution.

Best For

B2B SaaS companies that want SEO measured against pipeline and monthly recurring revenue, not just organic traffic.

Industries

Omnius has built its reputation around revenue-focused SEO for SaaS companies. They combine content strategy, technical SEO and conversion rate thinking into a single growth framework. Their AI SEO offering centres on entity authority building and structured content that improves visibility across both traditional search and AI-generated answers.

Being a smaller agency means clients work directly with the people doing the work, which isn’t always guaranteed at larger outfits.

Services

AI SEO, GEO, entity optimisation, technical SEO, SaaS content strategy, AI citation building and conversion-focused content.

Best For

SaaS businesses at growth stage that want SEO and AI SEO working together as part of a broader revenue strategy.

Industries

If you need to build content infrastructure quickly and want it designed for AI retrieval from the start, they know how to set that up.

AI content automation, programmatic SEO, GEO, content strategy, AI workflow design, technical SEO and LLM-ready content frameworks.

Location: London, United Kingdom

Overview

Reboot Online is a data-driven agency with a long track record in technical SEO and digital PR. Their approach is anchored in original research: they regularly publish studies on factors affecting organic visibility, which informs their client work and builds the kind of citation authority that matters more as AI search grows.

It’s a research-first culture that stands out in an industry often dominated by opinion and assertion.

Services

Technical SEO, digital PR, data-led content, AI visibility tracking, entity optimisation, link acquisition and schema implementation.

Best For

Enterprise businesses and ambitious mid-market companies that want technical rigour alongside content and PR capability.

Industries

What is AI SEO?

AI SEO is the practice of optimising your digital presence to perform well across both traditional search engines and AI-powered platforms: ChatGPT, Google AI Overviews, Gemini, Perplexity and Claude.

Traditional SEO focuses on rankings. You identify keywords, create content that addresses those queries, build authority through links and engagement, and monitor positions in the SERP. The metric that matters most is organic traffic.

AI SEO adds a different objective. In addition to rankings and traffic, you need your content to be retrieved, cited and surfaced inside AI-generated answers. That changes what you optimise for:

  • Traditional SEO optimises for keyword relevance and ranking position
  • AI SEO also optimises for entity recognition, structured information and LLM retrieval likelihood
  • Traditional SEO measures clicks and traffic
  • AI SEO also measures citation frequency, AI Overview appearances and LLM visibility share

Generative Engine Optimisation (GEO) is the specific discipline within AI SEO that focuses on AI-generated content environments. Where traditional SEO considers how Google’s algorithm ranks pages, GEO considers how large language models understand, trust and reference information when composing answers.

The relationship between AI SEO and traditional SEO isn’t competitive; it’s cumulative. A brand with strong SEO fundamentals, good technical health, topical authority, quality content and trusted links is already better positioned for AI visibility than a brand that has neglected those fundamentals. AI SEO adds targeted work on top: entity optimisation, structured data, information gain content and citation monitoring.

Is AI SEO Replacing Traditional SEO?

Any agency claiming it is would be oversimplifying.

According to Search Engine Land, Google now processes more than 5 trillion searches per year, or roughly 14 billion per day. The blue-link SERP remains the primary search interface for the majority of users. Click-through rates from organic rankings still drive enormous volumes of traffic. Traditional SEO: keyword research, content, link building and technical site health, continues to matter.

What’s changed is the context. According to SparkToro’s 2026 research, 68% of Google searches now end without a click, with AI Overviews playing a growing role in suppressing outbound clicks on informational queries. ChatGPT and Gemini capture a portion of search journeys that would previously have gone through Google. Perplexity is growing as a research tool, particularly among professionals. These are real shifts, but they add to the search picture rather than replace it.

Here’s the right framing: good SEO powers AI SEO. The technical and content signals that help your brand rank well also help AI systems understand and trust your content:

  • Crawlability ensures AI crawlers can access your content in the first place
  • Domain authority and quality backlinks signal trustworthiness to both Google and LLMs
  • Structured data helps AI systems understand entities, relationships and facts
  • Content quality, meaning depth, accuracy and original insight, is what AI systems cite most readily
  • Topical authority improves retrieval likelihood across both search and AI platforms

Good SEO and AI SEO work together. The brands that will struggle are those that treat them as separate disciplines requiring separate strategies. The foundation is the same, even if some of the optimisation work differs.

What Services Do AI SEO Agencies Provide?

The service mix varies between agencies. Some focus exclusively on AI and GEO; others offer it as part of a broader SEO proposition. Here’s what the most capable agencies typically cover.

GEO Audits

A GEO audit evaluates how well your current content, technical setup and entity signals position you for AI-generated visibility. It identifies gaps in structured data, entity recognition and content information gain, and produces a prioritised roadmap for improvement.

AI Visibility Tracking

Most traditional SEO reporting tools don’t measure AI search visibility. Specialist agencies use tools and monitoring processes to track how often your brand is cited in ChatGPT responses, Google AI Overviews, Perplexity answers and Gemini. This creates a measurable baseline and tracks progress over time.

Entity Optimisation

Entities are the named concepts: brands, products, people, places, topics. AI systems use them to understand meaning. Entity optimisation ensures your brand is clearly defined and consistently represented across your own content, third-party sites, knowledge graphs and structured data. A brand that’s well understood as an entity is more likely to be cited accurately.

Structured Data Implementation

Schema markup tells AI systems and search engines exactly what your content is about: product details, FAQs, how-to steps, organisation information, reviews. Well-implemented structured data improves both traditional SERP features and AI retrieval accuracy. Research from Semrush indicates that pages with valid structured data appear significantly more often in AI-generated summaries.

Technical SEO

The technical foundations remain essential. Crawl efficiency, indexation health, page speed, Core Web Vitals, mobile performance and JavaScript rendering all affect whether AI systems can access your content at all. Technical SEO is not optional in an AI search world; it’s the prerequisite for everything else.

AI Content Optimisation

Existing content can often be improved for AI retrieval without a full rewrite. This involves adding clear factual statements, improving structure with headings and lists, integrating relevant entities naturally and ensuring content directly answers the questions your audience asks AI assistants.

AI Overview Optimisation

Google AI Overviews pull content from pages that Google trusts to answer a query accurately and concisely. Optimisation for AI Overviews involves identifying queries where your site should appear, auditing the content that competes for those positions and improving content to meet Google’s citation criteria.

Digital PR and Citation Building

AI systems cite sources they trust. Building a strong citation footprint through digital PR, thought leadership, data journalism and authoritative mentions in relevant publications increases the probability that your brand appears in AI-generated answers. It’s one of the most important elements of an AI SEO strategy and one of the most commonly underweighted.

LLM Visibility Monitoring

Tracking how ChatGPT, Gemini, Claude and Perplexity reference your brand across different query types provides intelligence that informs content and PR strategy. LLM monitoring tells you where you’re being cited, where competitors appear instead of you and which content formats generate AI visibility.

Information Gain Content

Content that contains original data, proprietary research or expert commentary that doesn’t exist elsewhere performs better in both traditional search and AI retrieval. Agencies with strong content capability produce information gain content as a deliberate strategy, not an afterthought.

What is Information Gain and Why Does it Matter?

Information gain is the additional value a piece of content provides beyond what’s already available on the subject. Google’s systems have referenced it as a quality signal for years. For AI systems, it’s arguably more important again.

When an AI model generates an answer, it draws on content it has indexed and can retrieve. Content that simply rephrases what dozens of other pages already say gives an AI system no reason to cite it over any other source. Content that contains something unique, a proprietary study, original survey data, an expert perspective not available elsewhere, a case study with real numbers, gives an AI system a specific reason to reference that source.

So what does information gain content look like in practice?

  • Original research: surveys, experiments and data analysis your team has conducted
  • Proprietary data: benchmarks or aggregated insights drawn from your own experience
  • Expert commentary: quotes and analysis from practitioners with genuine credentials
  • Specific examples: detailed case studies with real outcomes rather than generic principles
  • Nuanced viewpoints: positions that add analysis not well-represented in existing sources

A useful test: if you removed the unique elements from your content, would it be indistinguishable from ten other pages on the same topic? If yes, it lacks information gain.

Agencies that understand AI SEO invest in information gain as a deliberate content strategy. It’s one of the clearest differentiators between content that earns AI citations and content that doesn’t.

How to Choose an AI SEO Agency

The AI SEO agency market is growing quickly, and with that growth has come a significant amount of noise. Here’s a practical set of criteria for evaluating potential partners.

AI Expertise

Can the agency explain concretely how they approach GEO and LLM visibility? Do they understand the difference between how Google AI Overviews select content and how ChatGPT retrieves information? Vague references to “AI-powered SEO” aren’t the same as genuine capability.

Technical SEO Capabilities

AI visibility depends on strong technical foundations. An agency that can’t confidently handle crawl issues, structured data and site architecture is not well-positioned to deliver AI SEO results, regardless of how their services are marketed.

Industry Experience

SEO strategy varies significantly between ecommerce, SaaS, B2B, local and enterprise contexts. An agency with specific experience in your sector will understand the commercial context, the competitive landscape and the typical challenges far better than a generalist.

Reporting and Measurement

Ask specifically how they measure AI visibility. A credible AI SEO agency should report on AI Overview appearances, LLM citation monitoring and entity recognition alongside traditional metrics. If reporting only covers rank positions and sessions, they’re not accounting for AI search performance.

Entity Optimisation Skills

Ask how they approach entity building and what their process is for ensuring your brand is understood consistently across different AI systems. Meaningful differences exist between agencies on this.

GEO Strategy

Request examples of GEO strategy developed for clients. What does a GEO audit look like? How do they prioritise which AI platforms to focus on? What content changes do they recommend to improve citation probability?

Case Studies

Look for case studies with measurable outcomes: revenue growth, lead volume, AI visibility improvements. Be cautious of case studies that show only rankings or traffic without connecting those metrics to business results.

Proprietary Tools

Some agencies have built or licensed tools specifically for AI visibility tracking and GEO auditing. Having proprietary tools signals genuine investment in the discipline rather than retrofitted processes. Ask what tools they use and why.

How Much Do AI SEO Agencies Cost in 2026?

AI SEO pricing varies widely depending on scope, technical complexity, the level of content production involved and the competitiveness of your sector.

Service Estimated Monthly Cost
Small business AI SEO£1,000 – £3,000
Mid-market campaigns£3,000 – £8,000
Enterprise AI SEO£8,000 – £25,000+

These ranges are illustrative. Projects with significant technical debt, competitive markets or high-volume content requirements may sit above them. One-off audits and consultancy engagements are typically priced separately.

Be cautious of very low-cost AI SEO offers. Effective GEO and AI SEO work requires technical expertise, content quality and ongoing monitoring, and none of that can be delivered well at very low price points.

Frequently Asked Questions

What is AI SEO?

AI SEO is the practice of optimising your digital presence to perform well across both traditional search engines and AI-powered platforms: ChatGPT, Gemini, Claude and Perplexity. It combines technical SEO fundamentals with GEO and LLM visibility strategies.

What is Generative Engine Optimisation?

Generative Engine Optimisation (GEO) is the discipline focused on improving your brand’s visibility within AI-generated answers. It involves entity optimisation, structured content, information gain strategies and digital PR designed to make your content more likely to be cited by AI systems.

What’s the difference between AI SEO and GEO?

AI SEO is the broader term, covering all optimisation work relevant to AI-influenced search. GEO is a subset: specifically focused on generative AI platforms and how content is retrieved and cited within AI-generated answers.

Which AI platforms should you optimise for?

The four most commercially relevant platforms in 2026 are Google AI Overviews, ChatGPT, Gemini and Perplexity. The right prioritisation depends on your audience. B2B buyers are heavier users of ChatGPT and Perplexity, while consumer queries more commonly involve Google AI Overviews and Gemini.

How long does AI SEO take?

Technical improvements can show results within weeks. Content and entity work typically takes three to six months to meaningfully influence AI visibility. Building citation authority through digital PR is a longer-term commitment: expect six to twelve months for significant results in competitive sectors.

Can AI SEO work for ecommerce businesses?

Yes, and it’s increasingly important for them. Shoppers use AI assistants to research products, compare brands and identify retailers before they buy. Ecommerce brands that appear in those AI-generated research answers are influencing purchase decisions before the shopper ever visits a search engine. Our ecommerce SEO services build AI SEO strategy specifically around the ecommerce purchase journey.

How do AI models decide which brands to cite?

AI models cite sources they’ve been trained on and that appear frequently in authoritative, trusted contexts. The key factors are domain authority, content clarity and factual accuracy, entity recognition, information gain and structured data that helps AI systems parse and retrieve information accurately.

How do you measure AI search visibility?

Through a combination of methods: tracking Google AI Overview appearances for target queries, monitoring ChatGPT, Gemini and Perplexity responses to relevant searches, using tools like Semrush’s AI Toolkit or Ahrefs’ AI features, and tracking brand mentions across AI platforms. It’s a young measurement discipline, but credible agencies have established processes for it.

Is AI SEO worth it for smaller businesses?

For smaller businesses with limited budgets, solid SEO fundamentals should come first, as these also support AI visibility. Dedicated GEO work becomes more valuable as the business grows and competes in more competitive spaces. Getting schema markup implemented correctly and your Google Business Profile optimised are quick wins with AI visibility benefits attached.

Can AI SEO increase leads?

Yes. Appearing in AI-generated answers for high-intent queries, product recommendations, service comparisons and “best of” roundups drives brand awareness and direct traffic. B2B companies in particular find that being consistently cited in AI answers for buyer-journey queries generates qualified inbound interest over time.

Looking for an AI SEO Agency?

If you’re running an ecommerce business and want to build visibility across both traditional search and AI platforms, we’d love to talk.

We combine strong technical SEO foundations with GEO strategy, content and digital PR. We treat AI search visibility as part of an integrated growth programme, not a standalone service bolted on top.

Whether your goal is appearing in Google AI Overviews, being cited in ChatGPT responses when shoppers research your category or building the entity authority that supports long-term organic growth, we’ll build a strategy that connects SEO and GEO into a single commercial approach.
