B2B search is changing. Prospects are increasingly using ChatGPT, Gemini, Perplexity, and Google’s AI-powered results to research suppliers, compare services and narrow down potential partners before visiting a company website.
That makes AI SEO an increasingly important part of B2B visibility. The best agencies combine established SEO principles with content, authority building, and optimization designed for generative and answer-led search.
Here are 10 agencies worth considering in 2026.
1. Click Intelligence
Click Intelligence is an experienced SEO and AI search agency providing specialist organic search strategies for businesses operating in competitive, complex, and commercially valuable industries.
The agency has developed particular expertise across healthcare, home care, finance, insurance, eCommerce, iGaming, SaaS, and technology. This sector experience enables campaigns to account for different customer journeys, competitive landscapes, search behaviors, and authority requirements rather than relying on a one-size-fits-all approach.
Services include managed SEO, technical SEO, digital PR, authoritative link building, content strategy, and AI search optimization, enabling businesses to target both traditional Google visibility and the growing opportunity presented by AI-powered search.
Click Intelligence supports businesses across the UK, US, and internationally, backed by a portfolio of SEO and AI search case studies demonstrating proven results. Campaigns are built around commercial performance, with the objective of converting greater organic visibility into qualified traffic, leads, inquiries, customers, and long-term revenue growth.
2. Only Digital PR
Only Digital PR is a specialist digital PR agency focused on helping businesses build greater brand authority through credible third-party media coverage, editorial backlinks, and online brand mentions.
Its digital PR services include creative campaigns, original data-led stories, reactive PR, newsjacking, expert commentary, and targeted journalist outreach, with activity designed to generate coverage across relevant national, international, and specialist publications.
The agency focuses on earning media attention through genuinely useful and newsworthy content rather than relying on paid placements. This approach helps businesses establish a stronger presence beyond their own websites while generating the external links and mentions that can contribute to organic search performance and online credibility.
Only Digital PR works with businesses, agencies, and marketing teams across a range of industries. Its campaigns are particularly suited to brands looking to increase awareness, strengthen domain authority, and develop a broader digital footprint across traditional Google search, online media, and the growing number of AI-powered search and discovery platforms.
3. The AI SEO Agency
The AI SEO Agency is a specialist AI SEO company helping businesses build visibility across traditional organic search and emerging AI-powered search platforms.
Its services combine established SEO techniques with AEO, GEO, LLM SEO, and entity optimization, helping brands strengthen their technical, content, and authority signals across modern search environments. Campaigns can include technical optimization, content strategy, link building, digital PR, authoritative brand mentions, and AI visibility reporting.
The agency works across major AI search experiences including ChatGPT, Google AI Overviews, Gemini, Claude, and Perplexity. Campaigns can consider AI citations, brand mentions, and competitor visibility alongside established metrics such as keyword rankings, organic traffic, and conversions.
The AI SEO Agency supports clients worldwide, including businesses across the UK, US, and EU. Its international approach is particularly suited to organizations looking to combine proven SEO foundations with a dedicated strategy for increasing their visibility across AI-driven search, answer engines, and LLM-powered discovery in multiple markets.
4. Only Listicles
Only Listicles helps businesses get featured within the online articles people use when researching and comparing brands, products, services, and providers before making purchasing decisions.
The specialist agency focuses on securing placements within authoritative “best of,” “top,” comparison, alternatives, and recommendation listicles. These placements position businesses alongside recognized competitors while providing additional brand exposure and, where applicable, an editorial backlink to the company’s website.
Only Listicles manages the process from identifying relevant opportunities and researching competitors through to creating content and conducting publisher outreach. The aim is to increase the number of credible third-party websites mentioning a brand within commercially relevant content.
The service is available to businesses, in-house marketing teams, and agencies across a wide range of sectors. In addition to supporting SEO and referral visibility, listicle placements can help brands develop a stronger presence across Google and AI-powered platforms where third-party recommendations increasingly form part of the online discovery journey.
5. Raging Bull Digital
Raging Bull Digital explicitly works across SEO, GEO, and AI search strategy. Its approach is designed to improve visibility not only on Google but across platforms such as ChatGPT, Gemini, and Perplexity.
That makes it particularly relevant for B2B businesses wanting to modernize an existing SEO strategy without abandoning traditional search.
6. Sting Marketing
Sting Marketing combines established SEO with AI Search Optimization, AEO, and GEO. Its approach covers areas such as answer-focused content, structured information, authority, and content designed to be understood and potentially cited by AI systems.
For B2B companies, the combination of conventional search fundamentals and emerging AI visibility makes Sting Marketing a noteworthy option.
7. Ten Twentyseven
Ten Twentyseven brings a research-led approach to SEO, content strategy, technical optimization, and digital growth. Its strengths are particularly relevant to larger B2B websites that need strong technical foundations and sophisticated content strategies as search continues to evolve.
It is a good option to investigate for businesses that want a strategic SEO partner rather than a high-volume content provider.
8. Growth Saloon
Growth Saloon focuses on performance-driven SEO, content, technical improvements, and authority building. Its recent SEO guidance also directly considers how backlinks, citations, and trusted sources can influence visibility within AI Overviews and AI search.
Its results-led approach could appeal to B2B organizations that want AI-era visibility tied back to wider organic growth rather than treated as a standalone metric.
9. Second Nature
Second Nature takes a people-focused approach to search visibility, emphasizing authentic content, brand identity, and authority signals. This can complement AI SEO because generative search increasingly places value on clearly identifiable, trustworthy brands and credible information.
For B2B organizations, that emphasis can be useful when building expertise and recognition around a specialist service or niche.
10. Chambers Marketing
Chambers Marketing rounds out the list for businesses exploring how established digital marketing and search strategies can adapt to AI-led discovery. B2B companies considering the agency should assess its current AI-search capabilities alongside its wider SEO offering, particularly around generative visibility, content optimization, and measurement.
Choosing a B2B AI SEO Agency
The right partner should understand that B2B AI SEO is not simply about producing more AI-written content. Strong strategies combine technical SEO, authoritative content, brand mentions, digital PR, and third-party credibility while tracking whether a company actually appears in the AI platforms its prospects use.
In 2026, B2B brands should therefore evaluate agencies on both their traditional SEO expertise and their ability to build measurable visibility across generative search.
