Hiring a B2B SEO agency is a different decision from hiring a general search firm, because the buyer on the other side of the search box behaves differently. A procurement lead researching industrial sensors, a CFO comparing spend management platforms, or an IT director shortlisting managed security providers will rarely convert on the first visit. They read specifications, download documentation, forward pages to colleagues, and come back weeks or months later through a branded search, a sales email, or an answer in ChatGPT. Traffic volume tells you very little about whether any of that is happening.
The economics are also lopsided. A single enterprise contract can be worth more than a consumer brand earns from thousands of orders, which means ten highly qualified visitors searching a narrow technical phrase can matter more than ten thousand visitors reading a broad explainer. Good B2B SEO starts from that math. It prioritizes bottom-of-funnel content such as comparison pages, pricing explainers, integration pages, and use-case pages, and it measures success in opportunities and pipeline rather than sessions. The firms on this page are the ones that build their reporting around that reality, usually by connecting search data to a CRM such as HubSpot or Salesforce.
Buying committees add another layer. Research on B2B purchases consistently shows several stakeholders involved in each decision, and each one searches differently. The engineer wants tolerances and file formats, the finance lead wants total cost of ownership, and the executive sponsor wants proof that peers have done this before. Specialist B2B SEO services map content to each of those roles and to each stage of a long sales cycle, and they know how to write credibly about complex products, often by interviewing in-house subject matter experts instead of paraphrasing competitors. If content is your main bottleneck, our guide to content marketing agencies for B2B covers firms that lead with editorial production.
Finally, AI search has changed where B2B discovery happens. Buyers increasingly ask large language models for vendor shortlists, and those answers draw on the same signals that SEO has always rewarded: clear entity information, authoritative mentions, structured data, and pages that answer specific questions well. Most of the firms below now package generative engine optimization (GEO) or answer engine optimization (AEO) alongside classic search work. For firms that lead with that discipline, see our separate roundup of AI SEO agencies.

Best B2B SEO Agencies In 2026
1. Ten Speed — Organic Growth Programs Tied To B2B Pipeline And LLM Visibility
Ten Speed is a Chicago-headquartered organic growth agency founded in 2020 by Nate Turner and Kevin King. The team of 15 full-time marketers works remotely across the United States, and the firm describes its mission as helping B2B companies increase search visibility across Google and LLMs to generate more pipeline. Its program combines SEO and AEO strategy, technical SEO, content creation and repurposing, digital PR, and design under one roadmap.
What earns Ten Speed the top spot is how explicitly it measures itself in revenue terms. The agency reports more than $50M in organic ARR generated across clients, more than 300 strategies delivered, over 8,000 content pieces created, and a client NPS above 70. Its published case study for Visible shows an 800% increase in organic traffic, a 110% lift in organic trials, and more than $1M in organic ARR. Named clients include Visible, Workvivo, Bitly, and ProsperOps.
The client mix is broader than software. Ten Speed lists professional services, hardware tech, data and AI, healthcare, fintech, education, and cybersecurity among its industries, which makes it a strong fit for B2B companies that sell a considered product and need content that works across a buying committee. Teams that want one partner to own strategy, production, and thought leadership PR, rather than stitching together a content shop and a link vendor, should start here. Pricing is not published; the firm builds a custom proposal after a discovery call.
2. Percepture — B2B SEO And GEO For Technical Buyers In Complex Industries
Percepture was established in 2004 and is headquartered in New York City, with additional offices in Los Angeles, New Jersey, Miami, Chicago, Seattle, and Washington DC. The firm has 43 team members, is a five-time Inc. 5000 company, and is certified by the National Minority Supplier Diversity Council as a minority-owned business. Its B2B practice combines SEO, GEO, digital PR, content marketing, paid media, and conversion rate optimization.
Percepture positions its B2B SEO work around companies with long sales cycles and technical buyers. Its focus sectors include telecom, data centers, life sciences, healthcare, B2B SaaS, staffing, professional services, and private equity. In a published case study for Galorath, an aerospace and defense software company, the agency reports a threefold increase in qualified leads, a 76% increase in qualified traffic, and first-position rankings on priority keywords. Work for Broadstaff Global, a staffing firm, produced visibility across roughly 80% of targeted search terms.
Percepture is also one of the few firms here that publishes its pricing bands. B2B SEO runs from $3,000 to $5,000 per month at the starter tier, $5,000 to $10,000 for growth programs, and $10,000 to $25,000 or more for enterprise scope. That transparency, combined with PR capability under the same roof, makes it a good fit for regulated or highly technical companies that need both rankings and third-party credibility.
3. Altitude Marketing — B2B-Only Agency For Life Sciences And Industrial Search
Altitude Marketing is based at 225 Main Street in Emmaus, Pennsylvania, and has been in business for about 20 years. It describes itself as a B2B-only marketing agency, with more than 35 marketing experts on staff covering SEO, AEO, content, branding, web design, and digital advertising. That B2B-only stance matters: every account the team works on shares the same long-cycle, multi-stakeholder dynamics.
The agency concentrates on sectors where search terms are narrow and technical: life sciences, biotech, clinical trials, specialty chemicals, contract manufacturing, packaging and processing, industrial distribution, and technology. Its AEO approach emphasizes hyper-specific product content, structured data markup, long-tail keyword strategy, and quality backlinks from industry aggregators, which is exactly the kind of work that helps a chemical supplier or lab services firm surface in both Google and AI answers for precise queries.
Named clients include ZefSci, Chemical Concepts, and Sytheon. ZefSci’s director of marketing credits Altitude with helping drive sustained 20% business growth. Scientific and industrial companies that want an agency fluent in their buyers’ vocabulary, and that may also need a website rebuild alongside SEO, should put Altitude on the shortlist.
4. Kuno Creative — Employee-Owned HubSpot Diamond Partner For Industrial And MedTech Brands
Kuno Creative is an Ohio-based, employee-owned B2B marketing agency with more than 25 years of experience accelerating revenue growth for B2B brands. Its legal address is in Lorain, Ohio. The agency is a HubSpot Diamond Partner and a HubSpot Partner of the Year award recipient, holds HubSpot specializations in healthcare, software, and manufacturing, and is also a Google Partner and Semrush Partner Agency.
Kuno’s industry focus is industrial, technology and SaaS, medical device and MedTech, and sustainability. SEO sits inside a larger revenue program that also includes RevOps, website development, and sales enablement, and the agency now frames the search piece as AI SEO and brand visibility. Its case studies report a 1,373% increase in organic contacts for a MedTech company and an 1,800% jump in quote requests for a manufacturer. Named clients include ARAMARK, BASF, Samsung, Symplr, and Black Line Safety.
Kuno is the right call for mid-size and larger B2B companies that already run on HubSpot and want search traffic to flow into clean lifecycle stages and attribution reports. Because SEO is one part of an integrated offering, it suits buyers who want a single partner for inbound, CRM, and content rather than a pure search specialist.
5. POLARIS — UK B2B SEO And GEO Specialist Operating Since 2009
POLARIS was founded in 2009 and is headquartered at Chalfont Park in Chalfont St Peter, near Gerrards Cross, in the United Kingdom, with operations in Ireland and the USA. It calls itself a specialist GEO, AI search, and SEO agency and describes itself as a leading B2B SEO agency with more than a decade of organic channel growth work. Services include technical SEO, website migrations, content marketing, digital PR, link building, analytics, and marketing training.
The B2B client roster is strong: Thomson Reuters, Sodexo, CACI, Reachdesk, Sidetrade, and Six Degrees all appear on the site. POLARIS reports a 420% increase in leads for Sodexo and an 1,100% performance increase for Milton Park. The agency won at the UK Search Awards in 2025 and has been a winner and finalist at the European Search Awards.
POLARIS is a natural choice for UK and European B2B companies, particularly those planning a site migration or replatform where rankings are at risk. Its migration experience, combined with GEO work aimed at Google AI Overviews, ChatGPT, and Perplexity, suits established brands that need to protect existing visibility while building presence in AI answers.
6. RevenueZen — Interview-Led B2B SEO For Professional Services And Tech Firms
RevenueZen is a Portland, Oregon agency founded in 2017 by Alex Boyd and led today by CEO Rocky Pedden. The team of about ten people is spread across Oregon, California, Arkansas, Pennsylvania, and New York. Its services center on B2B SEO, generative engine optimization, content strategy, technical SEO audits, LinkedIn content marketing, and interview-led AI content creation.
That interview-led approach is the reason to hire RevenueZen. Instead of writers summarizing what already ranks, the team pulls expertise out of client leaders and turns it into search content, which is especially valuable for professional services firms and technical companies whose differentiation lives in their people. RevenueZen lists SaaS and B2B tech, healthcare and health tech, professional services, renewable energy, and financial services among its industries. It reports 384% average organic traffic growth across clients and names Expensify, Dooly, Hiline, and Pritchard Industries among past partners.
The small, senior team suits consultancies, advisory firms, and founder-led B2B companies that want their expertise, not generic copy, to show up in Google and AI answers. Pricing and contract terms are not published.
7. Red Evolution — B2B SEO For Engineering, Energy And Industrial Tech Companies
Red Evolution is a B2B industrial and technology marketing agency founded in 2003 and headquartered in Aberdeen, Scotland, with further offices in Edinburgh and London. It positions itself as a specialist in B2B search for engineering and tech companies, and as a boutique by design that works with a small number of clients. Alongside SEO, the team handles strategy, web design and development, PPC, content, video, podcast production, and HubSpot implementation.
The agency’s roots in Aberdeen show in its client list, which leans heavily toward energy and engineering: Wood, Subsea 7, Coretrax, Glacier Energy, Hoover Pumping, OEG Renewables, Stats Group, and Pisys all appear on the site. Its SEO process is built around technical products, complex specifications, and long procurement cycles, covering keyword research, technical SEO, content strategy, and ongoing optimization. Red Evolution frames the stakes with a point industrial marketers will recognize: buyers are largely decided before they ever contact a supplier, so being found during that silent research phase is what fills the pipeline.
Red Evolution reports that 95% of its clients are retained for three years or more. It is a HubSpot Solutions Partner, a Google Partner, ISO 9001:2015 certified, a certified B Corporation, and an Otterly AI partner. The agency is open about cost: clients typically invest four figures per month, with some approaching five, and most B2B clients see clear improvements within three to six months. Engineering, energy, and industrial technology firms in the UK and beyond that want a senior, sector-literate team should shortlist it.
8. Hop AI — SEO And GEO Built Exclusively For Cybersecurity Vendors
Hop AI, formerly Hop Online, is led by CEO and founder Paris Childress and operates from Sofia, Bulgaria, and New Orleans, Louisiana. Its team of 30-plus specialists spans SEO, PPC, social, content, analytics, and creative. The agency now works exclusively with cybersecurity companies, helping them define their edge and generate pipeline through AI-enhanced marketing.
Cybersecurity is one of the hardest B2B categories to rank in. Buyers are skeptical, terminology shifts quickly, and a handful of large vendors dominate generic terms. Hop AI’s single-vertical focus means its strategists already understand how CISOs, SOC managers, and security engineers search, and which content formats earn trust with them. Services include B2B SEO, generative engine optimization, content marketing, paid search, and paid social. Named clients include Rapid7, Immersive Labs, Group-IB, SecurityScorecard, and CyberOne Security. The agency holds Google Premier Partner status.
Security vendors that want an agency with category knowledge on day one, and that plan to run search alongside paid acquisition, should talk to Hop AI. Pricing is not published on the site.
9. Siegers Media — B2B SEO For Manufacturers In German And English
Siegers Media GmbH is based in Uster, Switzerland, and has specialized in B2B manufacturers since 2018. Led by Robert Siegers, the team works remotely across the German-speaking DACH region and serves clients in Germany, Austria, Switzerland, and international markets in both German and English. Services include B2B SEO, generative engine optimization, Google Ads, web design, and content marketing.
The firm reports more than 50 B2B manufacturing clients across metalworking and CNC, cement and concrete, machinery and spare parts, plastics and injection molding, automation and robotics, electronics and PCB, chemicals, medical devices, packaging, and renewable energy. Named clients include Zarges, Sundwiger Messingwerk, Chemische Fabrik Kalk, and MACK4D, whose CEO describes the result as a snowball effect with more leads every month.
Siegers Media publishes its pricing: monthly SEO runs from €1,500 to €4,500, covering 15 to 60 hours of expert work that spans keyword research, content briefs, copywriting, technical implementation, and link building. It also sets expectations of three to nine months for measurable results. Industrial companies selling across Europe, particularly those that need multilingual product content, will find few more focused options.
10. Digital Elevator — Fixed-Price AEO And SEO For Life Sciences And Healthcare Teams
Digital Elevator was founded in 2010 by Daniel Lofaso and operates as a fully remote company. It describes itself as an AI visibility and SEO company for mid-market B2B teams, built for in-house marketing directors and lean teams that cannot justify a large agency retainer but need more than a software tool.
The firm is strongest in healthcare, life sciences, biotech, medtech, and labtech, and also serves B2B SaaS, edtech, and ecommerce. It cites more than 60 documented case studies, with particular depth among contract research organizations, diagnostics firms, and bioservices providers. One biotech client, Halo Labs, saw a 1,182% increase in sessions referred by LLMs. Named clients include McKesson and Kelly Services.
Pricing is public and fixed-scope: AI visibility programs start at $3,000 and managed AEO and SEO starts at $3,500 per month, with scope agreed before work begins and no lengthy discovery phase. Scientific companies that want to appear when researchers ask AI assistants for vendors, and that prefer predictable costs, are the best fit.
How To Choose A B2B SEO Agency
Can They Connect Rankings To Pipeline?
Ask every candidate to show you a report that links organic sessions to contacts, opportunities, and closed revenue in a CRM. A credible B2B SEO company will explain how it handles multi-touch attribution when a buyer first finds you through search, returns through a webinar, and converts after a sales call. If the case studies only mention traffic growth, keyword counts, or domain rating, treat that as a warning sign. Several firms on this list publish metrics such as SQLs, demo bookings, and attributable ARR, which is the standard to hold everyone to.
Do They Understand Your Buyers And Your Product?
Technical B2B content fails when writers do not understand the product. Ask how the agency gathers subject matter expertise: interviews with your engineers and sales team, access to product documentation, review cycles with technical staff. Ask for writing samples in your category or an adjacent one. A firm that already works with manufacturers, security vendors, or life sciences companies will need far less hand-holding than a generalist learning your vocabulary on your budget. Industrial companies can also compare the specialists on our list of manufacturing SEO agencies.
How Do They Prioritize Bottom-Of-Funnel Content?
In a long sales cycle, the pages that matter most are often the least glamorous: comparison pages, alternatives pages, pricing and ROI explainers, integration pages, and industry-specific use cases. Ask to see a sample content roadmap and check the ratio of high-intent pages to top-of-funnel explainers. A good plan also maps content to each member of the buying committee so that the technical evaluator, the finance approver, and the executive sponsor all find something relevant.
What Is Their Plan For AI Search Visibility?
B2B buyers now ask ChatGPT, Perplexity, and Google AI Overviews for vendor shortlists, so your agency should be able to explain how it will measure and improve your presence in those answers. Look for concrete tactics such as structured data, entity and brand consistency, third-party mentions in industry publications, and question-led content. Ask how they track LLM citations or referred sessions today. If you need a broader marketing partner in addition to search, our list of B2B marketing agencies covers integrated firms.
Are The Pricing And Contract Terms Realistic For Your Sales Cycle?
B2B SEO often takes three to nine months to show meaningful lead flow, and longer to show closed revenue when deals take a year to close. Make sure the contract length, reporting cadence, and success metrics reflect that. Published price ranges on this list run from roughly €1,500 per month for focused manufacturing programs to $25,000 or more per month for enterprise scope. Compare what each retainer actually includes, such as the number of content pieces, expert hours, link acquisition, and technical fixes, rather than headline price alone.
Conclusion
The Top B2B SEO Agencies In 2026 share a few traits: they report in pipeline terms, they build content that speaks to technical buyers and whole buying committees, and they have adapted their work for AI search. Beyond that, the right choice depends on your category. Manufacturers and scientific companies will get the most from specialists such as Altitude Marketing, Siegers Media, or Digital Elevator, cybersecurity vendors from Hop AI, and broader B2B tech and services companies from Ten Speed, Percepture, POLARIS, or RevenueZen.
Whichever B2B SEO agency you shortlist, ask for attribution examples, category-specific writing samples, and a clear plan for AI visibility before you sign. If your firm specializes in B2B search and belongs on a future edition of this list, you can submit your company for review.
