Key Factors in Finding the Best B2B SEO Agency for Your Business
B2B SEO demands a different skillset to B2C. The agencies that genuinely understand this build their entire methodology around how B2B buyers actually research, evaluate, and produce outcomes measured in leads and pipeline, not just sessions and rankings. The criteria below reflect what separates credible B2B SEO specialists from generalist agencies that list B2B as one of many service areas.
To help determine suitability when you’re in the market for a B2B SEO Agency, our Account Director Amo Sokhi has put together several key factors to find the most relevant agency partner in 2026:
B2B SEO that Focuses on Lead Gen or Demand Gen
B2B SEO differs from B2C in that a B2B SEO Strategy has to influence multiple people over a longer period of time. You also need to determine whether your objective with SEO is lead generation or Demand Generation focused and assess whether they understand lead qualification processes. This is more for you to determine in terms of your B2B marketing strategy and how SEO fits in, but a good talking point with any B2B agency.
Understanding of Targeting
B2B SEO requires a strict focus on who your ideal customers are. Evaluate a B2B SEO Agencies suitability by understanding how they consider targeting within their campaigns, and how they can utilise your ICP data to target more effectively through content and onsite messaging. You need to know and feel that the B2B SEO Agency you are talking to has experience of this and knows how to target your Ideal Customer Profiles (ICP’s) at the various stages of your funnel. Ask them about what their methodology is when planning B2B SEO strategies and what works well in their experience.
Experience of your B2B Business / Sector / Industry
Having experience in your sector or industry is always valuable as transferrable knowledge and tactics can save time and also increases chances of success. For example, if you’re a SaaS or Financial Services business, you’ll be looking for a partner that understands the nuances of software marketing or regulatory compliance. Other industries, such as hospitality and events, will have their own specific problems that only experience can inform on.
Find out about each agencies background and what applicable case studies they have that they can relate to your business. B2B Content in particular is quite challenging to produce, so knowing the language, and topics related to your business for example gives an agency a great advantage in partnering with you.
Time to Effect B2B Rankings
A good B2B SEO Agency will start with quick wins first, identifying either existing content or rankings that can be increased for further exposure. This is a good approach to look out for because it will help you to justify your investment faster and also deliver a return on investment within the first few months of activity too.
By taking these factors into account and conducting thorough research, you can make an informed decision that propels your business towards SEO success.
| Criterion | What We Assessed | Weighting |
| B2B-Specific Track Record | Documented case studies in B2B contexts. Evidence of lead generation, pipeline contribution, or demand generation outcomes, not just traffic growth. | High |
| Pipeline & Revenue Focus | Whether the agency connects SEO activity to business outcomes: SQLs, MQLs, demos, pipeline value, or revenue. | High |
| ICP Targeting & B2B Methodology | Demonstrable approach to Ideal Customer Profile targeting, multi-stakeholder content, and the longer B2B sales cycle. Agencies applying B2C tactics with B2B terminology are excluded. | High |
| Sector & Vertical Expertise | Experience in B2B-relevant sectors: SaaS, Professional Services, Technology, Financial Services, Manufacturing, or similar. Transferable knowledge and case studies. | Medium |
| Technical SEO Capability | Ability to handle the technical foundations that B2B sites often require: site architecture, crawlability, JavaScript rendering, international SEO, and site migrations. | Medium |
| AI Search & GEO Readiness | A clear perspective on optimising for AI-powered search (ChatGPT, Perplexity, Google AI Overviews), increasingly the first touchpoint for B2B buyers in research mode. | Medium |
| Client Reviews & Reputation | Google or Clutch review scores (4.5+ preferred), volume of reviews, and evidence of long-term client relationships. | Standard |
Here we have compiled a list of B2B SEO agencies that you can consider as a part of your strategy in 2026.

Founded with 17 years of in-house B2B experience behind it, Gripped has developed a methodology designed around how B2B buyers research, evaluate, and make decisions, rather than using a repurposed B2C playbook. They operate as a genuine growth partner, working with marketing leaders, SaaS founders, and revenue teams to build organic search programmes that contribute directly to pipeline. They are a HubSpot Partner and Google Partner.
Gripped’s B2B SEO Services

3. Virayo
Website: virayo.com
Location: London, UK
Clutch Rating: 4.8 ★
Virayo is a specialist B2B SaaS SEO agency founded in 2012, headquartered in Boise, Idaho, and operating globally with UK and European clients. They have built a focused reputation for helping growth-stage software companies generate qualified pipeline from organic search, with a particular emphasis on connecting SEO activity directly to SQLs and ARR. Founder Robbie Richards is an active publisher on AI search strategy and how B2B SaaS brands should adapt to zero-click SERPs and LLM-driven discovery.
Virayo’s B2B SEO Services
Virayo offers end-to-end SaaS SEO including strategy, AI/LLM optimisation, technical audits, keyword strategy, content strategy and production, link building, analytics and reporting, and quarterly SEO reviews (QSOs). A notable differentiator is their agentic AI workflow integration, applying AI tooling directly to campaign execution alongside dedicated strategies for visibility in ChatGPT, Gemini, and Perplexity.
Why we’ve included Virayo
Virayo’s inclusion is validated by some of the most specific and commercially measurable case study results of any agency on this list. SPOTIO generated over 1,700 demos and $2.8M in new ARR from organic search under their strategy. ForUsAll grew monthly SQLs from 20 to 120 while reducing paid ad spend by 90%. Cedreo grew from 6,000 to 70,000+ monthly organic visitors with a 7x increase in trial signups.
4. Onely
Website: onely.com
Location: Helsinki, Finland & Austin, USA (serving Global & UK clients)
Google Business Rating: No review profiles.
Onely is a specialist technical SEO agency founded in 2012, with team members including Microsoft Bing advisory board participants and a client roster that includes IKEA, eBay, and Realtor.com. While not UK-headquartered, they operate globally and regularly serve UK enterprise B2B clients. Their positioning is deliberately narrow: they focus on the technical foundations and AI search visibility challenges that complex enterprise websites face, the problems most B2B-generalist agencies cannot competently address.
Onely’s B2B SEO Services
Onely’s services include enterprise-grade technical SEO, JavaScript SEO for React/Next.js/Vue frameworks, Generative Engine Optimisation (GEO) for AI search citation, AI-aware website migration, information architecture, international SEO, and traffic drop recovery. A defining feature is their engineering-led delivery model: they work directly in client Jira, attend sprint planning, and build repeatable QA processes rather than delivering static PDF audits.
Why we’ve included Onely
Onely earns its place on this list because B2B buyers increasingly begin their research in AI search environments (including ChatGPT, Perplexity, Google AI Overviews) and technical SEO failures are often the reason brands are invisible in those environments, not just traditional SERPs. Their proprietary conversation-intelligence methodology, which analyses how real buyers discuss problems rather than just what keywords they search, is a genuinely differentiated approach. For enterprise B2B organisations with technically complex websites, JavaScript-heavy architectures, or a strategic need to build AI search visibility, Onely addresses challenges that other agencies on this list largely sidestep.
5. 93x
Website: 93x.agency
Location: London, UK
Google Business Rating: No review profiles.
93x is a London-based B2B SEO and digital marketing agency dedicated entirely to technology, software, and SaaS businesses. Founded in 2012, they have built a focused practice around the specific content, UX, and search challenges that technology companies face, where product complexity, technical audiences, and long evaluation cycles require a fundamentally different approach to B2C or generalist B2B marketing. Their full-service offering spans SEO, content, web design, and PPC, with organic search and content forming the core of their work.
93x’s B2B SEO Services
93x’s services include SEO research and planning, keyword strategy, on-page and technical SEO optimisation, UX design and development, user research and customer journey mapping, content strategy and production, and PPC. Their approach is informed by a deep understanding of the B2B tech buying process, with a focus on quality lead generation from the right ICP rather than raw traffic volume.
Why we’ve included 93x
93x’s strength is their near-exclusive focus on tech and SaaS B2B: a genuine specialism that translates into faster ramp-up time, more relevant content, and stronger contextual knowledge than a generalist agency can offer. Their understanding of the nuances of software marketing, product-led content, and the research-heavy buying journeys of technical decision-makers is evident in their published work.
6. Skale.so
Website: skale.so
Location: London, UK
Google Business Rating: No review profiles.
Skale is a London-based SEO agency founded in 2016 that specialises in SaaS brands.

Skale takes a personalised approach to each engagement, developing bespoke SEO models aligned with their clients’ KPIs rather than templated service packages.

Skale’s B2B SEO Services
Skale’s B2B SEO services cover SEO management and strategy, content planning and production, link building, and SEO website migrations. Their service methodology focuses on business growth metrics, prioritising KPI-aligned outcomes over vanity measures, and they provide fractional technical support for SaaS companies with existing in-house teams who need specialist depth without full-agency overhead.
Why we’ve included 93x
Skale’s inclusion reflects the specificity of their SaaS focus and the credibility of their client base. Working with brands like HubSpot and Usertesting, companies with sophisticated in-house marketing teams, signals a level of specialist expertise that earns agency partnerships rather than simply filling capability gaps. Their pricing and fractional support model also makes them a pragmatic option for well-resourced SaaS companies that want deep expertise on specific initiatives without a full retainer commitment.
7. Impression Digital
Website: impressiondigital.com
Location: Nottingham & London, UK
Google Business Rating: 4.8 ★
Impression Digital is a UK-based digital marketing agency with offices in Nottingham and London, widely recognised for their innovative approach to SEO and their consistent performance at UK industry awards. Founded in 2012, they work with a broad range of B2B clients alongside consumer brands, bringing a data-driven and creatively led approach to organic search that balances technical excellence with content quality. They are a well-respected voice in the UK SEO community and regularly contribute to industry research and events.
Impression’s B2B SEO Services
Impression’s B2B SEO services include technical SEO, content marketing and copywriting, link building, international SEO, local SEO, SEO audits, site migrations, and on-page optimisation. Their methodology combines technical depth with creative content and authority-building, making them a strong choice for B2B brands that need organic growth across multiple channels and content types simultaneously.
Why we’ve included Impression Digital
Impression earns its place through a sustained track record of award-winning work and a strong reputation within the UK market.

SEO Work’s B2B SEO Services
Their B2B SEO services include organic SEO strategy, technical SEO, digital PR, content marketing, local SEO, PPC, and paid social. For B2B clients, they bring sector-specific knowledge across manufacturing SEO, B2B lead generation, and multi-location or multi-market strategies, alongside strong analytics and attribution reporting.
Why we’ve included SEO Works
The SEO Works earns its place through scale, awards recognition, and independently verified performance. Multiple UK Digital Growth Awards wins, Google Premier Partner status, and a 4.8 Google rating across significant review volume collectively signal consistent quality. Their particular strength for B2B clients in traditional sectors, manufacturing, professional services, franchise networks, and B2B services, where deep industry context matters alongside technical SEO, makes them a well-suited partner for businesses outside the SaaS or technology vertical.
9. Go Up
Website: goup.co.uk
Location: London, UK
Google Business Rating: No review profiles.
Go Up is a London-based SEO agency with a clear values-led identity: they work with green innovators, good causes, and purpose-driven businesses, and are committed to sustainability across both their client work and internal operations. Beyond their mission, they are a credible full-service SEO agency with genuine depth across strategy, content, link building, and digital PR. Their client base includes both commercial B2B businesses and not-for-profit organisations, and their approach is grounded in high-value traffic generation rather than volume metrics.
Go Up’s B2B SEO Services
Go Up’s services cover SEO strategy, technical audits, link building and outreach, content marketing, digital PR, and site migrations.

Why we’ve included Go Up
Go Up’s inclusion reflects their consistent delivery of commercially grounded SEO for B2B clients, combined with a strategic depth that is rare at their size.

Why we’ve included Clickslice
Clickslice’s strong client reviews, a clear ROI methodology, and a consultancy model that is well-suited to B2B businesses that want to develop internal SEO capability rather than remain entirely agency-dependent, makes them a notable entry for this list.

Choosing the Right SEO Agency for your B2B Business
Partnering with the right SEO agency can make all the difference for achieving your business objectives. While the market is inundated with options, it is important to choose a partner that not only meets but exceeds your expectations.
Throughout this exploration of top B2B SEO agencies, it is evident that each agency brings their own unique strengths to the table. Each of these agencies bring a wealth of knowledge and experience, providing businesses with an array of options to consider when selecting the ideal SEO partner.
What are the benefits for B2B Businesses engaging an SEO Agency?
Partnering with the right SEO agency can unlock a number of benefits for your business across your marketing funnel and your sales cycle – as well as for your team as a whole.
- Improved visibility across a spectrum of search: the right agency will research to gain an awareness around which organic channels are the best for your specific sector – from the traditional SERP to AI search platforms – and then drive performance in the interfaces and touchpoints that matter.
- Tangible lead or demand generation growth: by aligning with your sales process and target profiles, an SEO agency can help drive your pipeline by targeting leads who search in a manner that suggests they meet your qualification process, providing you with leads that are more likely to convert.
- A productive, meaningful relationship: with the right fit, you won’t just get a partner who provides results, but one who you enjoy working with too. They use your terminology and discuss plans, issues and results in a language your business and stakeholders understand. You can enjoy a partnership that is honest, collaborative, and an SEO agency that cares about your business and the performance they are driving.
- Better efficiency for your resources: the right B2B SEO partner will be able to drive results at a return of investment that scales with the cost of the services and are accountable to their forecasting, providing you with clear detail on how your money is being used and the outcomes it is driving.
Frequently Asked Questions about B2B SEO Agencies
What is B2B SEO and how does it differ from B2C SEO?
B2B SEO is the practice of optimising a business’s organic search presence to attract and convert other businesses as customers. It differs from B2C SEO in several fundamental ways: B2B sales cycles are longer (often 3–18 months), decisions involve multiple stakeholders, the content required is more detailed and technically credible, and the commercial objective is typically lead quality over lead volume. Keyword strategies in B2B focus on intent signals from decision-makers and researchers within target organisations rather than broad consumer audiences.
What should I look for in a B2B SEO agency’s case studies?
Look for case studies that reference commercial outcomes like leads, pipeline value, SQLs, demos, or revenue, rather than just traffic growth or rankings. Strong B2B SEO case studies will specify the client’s sector and challenge, explain the strategic approach, and quantify the result in a way that connects to business impact. Be cautious of agencies whose case studies show impressive traffic numbers but make no reference to what that traffic produced commercially.
Should my B2B SEO strategy focus on lead generation or demand generation?
Most B2B businesses need both, in proportions that depend on their market. Lead generation SEO targets buyers already in-market and actively searching, capturing existing demand through transactional and comparison keywords. Demand generation SEO creates intent upstream through educational and thought leadership content that builds brand familiarity before a prospect is ready to search. If you’re in a well-established market with clear buying signals, lead gen should dominate your SEO strategy. If you’re in a nascent or niche market where buyers don’t yet know they have the problem you solve, demand gen content is essential groundwork.
Do B2B SEO agencies need sector experience to be effective?
Sector experience accelerates time-to-value but is not essential in every case. For complex or regulated sectors such as financial services, legal, medical, enterprise technology, an agency with direct sector experience will produce higher quality content faster and with fewer errors. For broader B2B categories, strong B2B SEO methodology is more important than vertical-specific knowledge, which can be acquired during onboarding. The most important thing is that the agency understands B2B buying behaviour regardless of the specific sector.
What is GEO and why does it matter for B2B SEO?
GEO (Generative Engine Optimisation) is the practice of optimising brand and content visibility in AI-powered search systems such as ChatGPT, Perplexity, Google AI Overviews, and similar tools. It matters for B2B because an increasing proportion of B2B buyers (particularly in technology and professional services) now use AI assistants for initial vendor research, shortlisting, and evaluation criteria. If your brand is not cited or recommended in AI search responses for relevant queries, you may be absent from the consideration set before a prospect visits your website. Forward-looking B2B SEO agencies will have a clear methodology for building AI search visibility alongside traditional SERP optimisation.
Engaging with an SEO Agency
If you’ve looking to engage an SEO agency for your B2B operation, the best way to do this is through a request for proposals process. For those who don’t know, this includes creating an RFP document that details some background on your business and current situation, why you want to engage with an agency, what your ideal agency and partnership format looks like, as well as some details on the pitching process.
Creating an RFP from scratch can be difficult, but you can access our RFP template to help you get started.
Next Steps
Businesses looking for a new SEO agency should carefully evaluate their specific needs and preferences to find the agency that best aligns with their objectives and aspirations in the digital world. Whether its one of the agencies discussed or another agency alike, selecting the right partner ensures that your business can navigate the complex world of digital marketing with confidence, driving tangible results and achieving your business objectives.
