Best B2B SEO Agencies in the UK (2026): 11 Checked

B2B buyers in the UK increasingly meet an AI answer before they meet a supplier’s website. Ofcom found that about 30% of UK searches now show an AI Overview, and 53% of adults say they see them often (Ofcom Online Nation 2025). A B2B SEO agency’s job is to put your firm on the shortlist in both places, and then on the call list of your sales team.

We searched Google UK for “b2b seo agency”, “seo agency b2b”, “b2b seo services” and 21 related terms on 22 October 2026. Google’s AI Overview for “seo agency b2b” named five firms: Push Group, Polaris, Definition, Hallam and Bulldog Digital Media. Much of the rest of page one was lists of agencies, so we read four of them. All three lists written by agencies put their own firm in first place.The fourth, from SEO Giant, calls itself independent and put Web Choice UK first. Between them the four named 32 firms, and only 5 appeared more than once. The same AI Overview gave a price of “£1,500 to £5,000+ per month” for small and mid-size UK B2B firms without naming a source.

So this guide starts from each agency’s own website. For every firm we noted where it is based, which B2B sectors it names, what its B2B SEO pages actually cover, one result it publishes, and any price it prints. Every fact is dated and linked.

A note on who wrote this. FactoryJet runs SEO for UK businesses, B2B firms included, so we are on this list, in the last group. That is a good reason to read every list, ours included, with care. Our list of the best SEO agencies in the UK covers every kind of business, our UK AI SEO and GEO list covers AI search specialists, and our UK ecommerce SEO list covers online stores. This one is only about firms that sell to other businesses.

A few terms first. B2B SEO is SEO for companies whose customers are other companies. The ICP (ideal customer profile) is the kind of company you most want to sell to. Bottom-of-funnel pages are the ones buyers read just before they get in touch: comparisons, pricing, “how we work” and case studies. Pipeline is the value of deals your sales team is working on. GEO (generative engine optimisation) is work aimed at being cited in AI answers such as ChatGPT and Google AI Overviews.

How we built this list

1. Start from the search results. We pulled Google UK results, AI Overviews and “People also ask” questions for 24 B2B SEO searches on 22 October 2026, including “b2b seo agency uk”, “saas seo agency uk”, “industrial seo agency”, “seo for professional services” and “b2b seo cost”.
2. Note who the AI answer names. Google’s AI Overview for “seo agency b2b” named five firms. All five are profiled below.
3. Read the lists that rank. We counted which agencies each list names and where each publisher put itself.
4. Check each agency on its own site. We read the B2B, SaaS, manufacturing, professional services, pricing, about and contact pages of 20 agencies on 22 October 2026. Every description below comes from those pages and links to them.
5. Keep only B2B work. A firm made the main list if its own site has a B2B, SaaS, manufacturing or professional services SEO page and names B2B clients or results. Firms we checked but did not profile are listed further down, with the reason.
6. No scores we cannot prove. We have not hired these firms, so there are no star ratings or rankings. We say who each one suits and give one question worth asking it.
7. Prices only from the firm. Where a firm prints a price, a rate or a minimum, we copy it exactly and link the page. We never guess another company’s price.

What each agency’s B2B SEO pages cover

Four jobs separate B2B SEO from ordinary SEO: pages for buyers who are comparing suppliers, moving a site without losing rankings, showing up in AI answers, and reporting results as leads or pipeline. This table shows which of the four each firm names on the B2B pages we read. “Not named” means we did not find it there, not that the firm cannot do it, so ask.

Eight of the eleven outside firms name AI search on their B2B pages, and two more sell it on a separate page. Seven name leads or pipeline reporting. Only three name comparison, pricing or demo pages, even though those are the pages a buying committee reads last. If a proposal does not mention them, ask why.

Which agencies show SEO work for UK manufacturers?

Manufacturing searches are small in volume but large in value: a few dozen searches a month for a specialist part can lead to a six-figure order. These two publish named manufacturing results on their own sites.

The SEO Works

Based: Sheffield (Fountain Precinct, Balm Green), with an office in London. Type: SEO, GEO and PPC agency, founded in 2009, with over 80 specialists.

The SEO Works has sector pages for B2B and for manufacturing, and its manufacturing case studies are the strongest of any firm here. Its B2B page says mid-funnel buyers look for comparison pages and service breakdowns and bottom-of-funnel buyers need clear service pages, trust signals and strong calls to action, and it targets the long, question-based searches that big rivals ignore. It runs migrations and GEO, and tracks share of voice in Google AI Overviews. It is the one firm here that also appears on our general and AI SEO lists for the UK.

• Best for: A UK manufacturer or industrial supplier that wants a large SEO team with proof in its own sector.
• B2B sectors named: Manufacturing, construction, logistics, software, legal, finance and other B2B sectors
• Clients named on its site: DHL, Office Reality, a Rotherham seating manufacturer and an industrial pump manufacturer (the last two unnamed)
• A result it publishes: A Rotherham cinema and stadium seating manufacturer now holds "60.6% share of voice in AI Overviews" for its priority terms. An industrial pump manufacturer "doubled organic traffic" and won a six figure contract.
• Price: No price published.
• Worth asking them: Which searches in your product range already show an AI Overview, and how it measured the 60.6% share of voice.

JDR Group

Based: Derby (Wyvern Business Park). Type: Inbound marketing agency and HubSpot partner, in business since 2004 and offering SEO since 2007.

JDR started as a business coaching company and sells SEO as one part of a full inbound plan: website, SEO, Google Ads, email and HubSpot CRM. That suits a manufacturer with one marketing person, which is the situation its construction equipment case study describes. It rebuilt that client’s site on HubSpot CMS, moved its CRM data from an old system and set up automated follow-up for inbound leads. It now sells AEO and GEO services too. It says it has more than 100 reviews on Google and HubSpot.

• Best for: A small or mid-size manufacturer with a thin marketing team that wants the website, CRM and SEO from one supplier.
• B2B sectors named: Manufacturing, construction equipment, technical training, accountancy and other SMEs
• Clients named on its site: IC2 CCTV and IC2 Distribution, Premier Forrester, a construction equipment manufacturer (unnamed)
• A result it publishes: A construction equipment manufacturer "tripled their website traffic and grown the number of inbound enquiries by over six times".
• Price: No SEO price published. Its pricing guide quotes a rule of thumb of 5 to 15% of annual revenue for marketing as a whole.
• Worth asking them: How much of the monthly fee is SEO, and whether you keep full access to your HubSpot site and data if you leave.

How much does a B2B SEO agency cost in the UK?

Usually £1,500 to £5,000 a month, more for SaaS and enterprise. Three UK guides we read on 22 October 2026 agree on the core range. Rudo says most UK B2B retainers “run from around £1,500 a month at the entry level to £5,000 or more for established programmes, with enterprise engagements reaching £10,000–£25,000-plus”. Gorilla Marketing puts professional services at “£1,500-£5,000/month minimum for meaningful progress” and says “£3,000-£8,000/month are typical for growing SaaS companies”. Whitehat SEO says most UK B2B companies spend £2,000 to £8,000 a month across two or three channels.

Here is what the agencies themselves print, copied exactly:

The other firms publish no SEO price. Definition’s hourly rate makes a useful yardstick: at £140 an hour, a £3,000 month buys about 21 hours of agency time, so ask any agency how many hours, pages and links your fee covers. For the full picture by business type, including audits, day rates and VAT, see our guide to SEO cost in the UK.

What a B2B SEO engagement should cover

Use this as a checklist when you compare proposals. The first month should be discovery: who buys from you, which searches they make, and which pages your sales team already sends to prospects.

Content built around the accounts you want

Account-based SEO starts from your ideal customer profile, not a keyword tool. If your best clients are mid-size logistics firms, the content should answer the questions their operations directors, finance leads and IT teams ask, in their words. Definition interviews clients’ subject matter experts and sales teams before writing, and Gripped says it will tell you if your ideal customer profile is too broad. Expect fewer, longer pages than a B2C plan, each written for a role in the buying group, with case studies from the same sector.

Comparison and pricing pages

B2B buyers build a shortlist before they contact anyone, and they search for comparisons (“X vs Y”, “alternatives to X”) and for prices. If you do not publish those pages, a competitor or a list site will, and AI answers will quote them instead. A pricing page does not need a rate card: ranges, what changes the price and how a quote works are enough. Gripped, The SEO Works and Bulldog name this work; ask every other agency whether it will build these pages and who signs off the claims.

Technical SEO for large and complex sites

Most B2B sites are small, but some are not: parts catalogues, documentation hubs, multi-country sites and software help centres. Google’s crawl budget guide (updated 22 July 2026) says crawl budget matters for sites with 1 million+ unique pages that change weekly, or 10,000+ pages that change daily. Below that, the usual problems are duplicate pages, slow templates, content that only appears after JavaScript runs and broken redirects after a rebrand. For a move to a new domain or platform, Google’s site move guide recommends permanent 301 or 308 redirects and warns against chains of redirects.

AI Overviews and assistant answers for B2B buying questions

Buyers now ask assistants questions such as “which payroll software suits a 200-person firm?” or “who supplies auditorium seating in the UK?”. Google’s guide to AI featuressays there are “no additional requirements” to appear in AI Overviews or AI Mode beyond normal SEO, so the same pages do the work: clear answers near the top, facts a model can quote, and your name on trade and review sites you do not own. The SEO Works’ seating manufacturer case is a good model: one well-structured page per buying question, then tracking which answers name you and which name a rival.

Reporting in leads and pipeline

Rankings and traffic are early signs, not results. Ask for reporting that follows an organic visit to a form fill, then to a sales conversation, then to a deal, which usually means joining your analytics to your CRM. Whitehat SEO tracks this through HubSpot, Bulldog names HubSpot, Salesforce and Zoho, and Definition reports inbound leads and cost per acquisition. With a sales cycle of six months, the first closed deal from SEO may arrive well after the first ranking.

How to choose a B2B SEO agency in the UK

Start with sector proof: one published result for a firm like yours, reported as leads or revenue, not only rankings. Then check fit. Google’s own advice on hiring an SEO(updated 5 June 2026) is to ask for examples of past work and how results will be explained, and it says plainly that “No one can guarantee a #1 ranking on Google.”

Add four B2B questions. Will you interview our sales team before writing anything? Which comparison and pricing pages will you build in the first three months? How will you report leads and pipeline as well as traffic? What is the notice period? The first answer tells you most: an agency that writes B2B content without talking to the people who sell will produce pages your buyers skim and leave.

If you sell to trade buyers online as well, our UK B2B ecommerce service covers trade portals and wholesale ordering, and our UK AI SEO service covers getting named in AI answers.
