The best B2B SEO agencies for 2026 are 1. Directive Consulting, 2. PipeRocket Digital, 3. OuterBox, 4. TripleDart, 5. Omniscient Digital, 6. SimpleTiger, 7. RevenueZen, 8. Victorious, 9. Orbit Media Studios, 10. Straight North, 11. Stratabeat, 12. Virayo, 13. Grow and Convert, 14. Sure Oak, and 15. Siege Media.
A B2B SEO agency is a team that helps companies selling to other businesses, from software firms to manufacturers and industrial suppliers, turn search and AI answers into qualified leads and pipeline. Your buyers are a committee of five or ten people, and they search for very specific things, often with a spec sheet or a compliance question in hand.
So that’s what we looked for: agencies that write for those buyers, handle the technical side of the site, show up in AI answers, and can show you the pipeline their work produced.
A note on who wrote this: PipeRocket Digital publishes this list and is one of the agencies on it, at #2. We scored ourselves on the same criteria as everyone else and kept the reasons you might not hire us in our own card. Nobody paid to be listed.

What Does a B2B SEO Agency Do?
A B2B SEO agency helps companies that sell to other businesses turn search and AI answers into leads and pipeline. That’s a different job from consumer SEO, because the buyer is a committee and the sale takes months. The good ones handle four parts of B2B SEO that a general agency usually doesn’t.
- Buying committees: pages for each person in the deal, the engineer checking the specs, the finance lead checking the cost and the manager who signs off.
- Technical and high-intent searches: low-volume, high-value terms like a compliance standard, a part number or “[your category] vs [competitor]”, instead of broad keywords picked on volume.
- AI search: getting your company cited in ChatGPT, Perplexity and Google’s AI Overviews, alongside classic rankings.
- Pipeline reporting: tracking SEO past traffic, through to demos, quote requests, SQLs and closed-won revenue.
Around that, most of them run the same core services: technical SEO, content and thought leadership, digital PR and link building, and conversion work that turns visits into booked calls.
Which B2B SEO Agency Fits Your Situation?
What you sell and your biggest gap matter more than the overall ranking. Here’s where we’d start for each:
| If your main need is… | Start with | Why |
|---|---|---|
| Proving SEO in pipeline to leadership | PipeRocket Digital, Directive Consulting, Omniscient Digital | All three report SEO against pipeline and closed revenue |
| A manufacturing, distribution or catalog site | OuterBox, Straight North, Orbit Media Studios | All three show named results for manufacturers and industrial suppliers |
| Comparison and alternatives pages for software | PipeRocket Digital, TripleDart, Grow and Convert | All three build the pages buyers read right before a demo |
| Showing up in ChatGPT and AI answers | PipeRocket Digital, TripleDart, Virayo | AI search sits with the same team as classic SEO, with tracking |
| Finance, legal, insurance or professional services | Victorious, Stratabeat, RevenueZen | All three work with finance, legal and professional services companies |
| Authority and links in a niche industry | Sure Oak, Victorious, Siege Media | All three are known for earning links from industry sites |
| Turning organic visits into quote requests and demos | OuterBox, Orbit Media Studios, Stratabeat | All three run conversion work as part of SEO |
| Published prices and flexible terms | PipeRocket Digital, RevenueZen, Orbit Media Studios | All three publish a price, and none needs a year-long contract |
How We Chose These B2B SEO Agencies
To make the list, an agency needed all three of these:
- Named B2B clients, or a B2B SEO case study with numbers.
- SEO as one of their main services.
- A verified rating with client reviews on Clutch.
That rule kept out some well-known names. First Page Sage, Breaking B2B and Growth Plays don’t have verified client reviews on Clutch or FeaturedCustomers. Kalungi and Powered by Search have good ratings, but SEO is one of many services for them. WebFX and Ignite Visibility have strong ratings too, but we couldn’t find a B2B case study with numbers on their B2B pages.
Then we scored everyone who passed on six things, each from 1 to 5. The 15 below are the agencies we’d shortlist first:
| Criterion | Weight | What earns a high score |
|---|---|---|
| Pipeline reporting | 25% | SEO reported through to SQLs, pipeline and closed-won revenue, connected to your CRM |
| B2B depth | 20% | A method built for buying committees and technical buyers, with named results in more than one B2B industry |
| Technical SEO and conversion work | 15% | Site architecture, migrations and catalogs, plus landing pages and CRO run by the same team |
| Content, links and AI search | 15% | Thought-leadership content, digital PR and link building, and a method for AI answers |
| Verified reviews | 15% | A high Clutch rating backed by a large number of reviews |
| Pricing transparency | 10% | A price published on the agency’s own site |
We scored ourselves the same way. For the full process, including how we handle that conflict of interest, read our research methodology and editorial policy.
The 15 Best B2B SEO Agencies
1. Directive Consulting
Best for: B2B tech companies that want SEO reported in closed-won revenue
Directive Consulting is an Irvine, California agency that runs SEO, paid media and CRO for B2B tech companies under what they call Customer Generation. Their clients include Seagate, AxisCare, Case Status and Sumo Logic.
Their B2B SEO method starts with a commercial opportunity assessment, then maps how decision makers research, compare vendors and build consensus. That map decides which solution pages get built first, and spend moves toward whatever is producing opportunities.
Reporting is connected to your CRM, so you see sales-qualified opportunities, cost per opportunity and closed-won revenue from organic search. Their technical audits cover the usual site health checks, and their recent case studies pair SEO with AI search work.
| Detail | Directive Consulting |
|---|---|
| Location | Irvine, CA |
| Founded | 2013 |
| Team size | 50-249 |
| Starting price | Custom |
| Rating | 4.8/5 (56 reviews) |
| Clients | Seagate, AxisCare, Case Status, Sumo Logic |
| More from us | Directive Consulting reviews, PipeRocket vs Directive Consulting, Directive Consulting alternatives |
Proof point: AxisCare, a home-care software company, grew organic traffic 70% and demos 200% from SEO and AI search work.
What clients say: A talent acquisition tech company that hired them for SEO, PPC and content wrote on Clutch that “this is the strongest agency I’ve worked with to date, and I would recommend them to anyone” (source).
Think twice if: you want an SEO specialist, because SEO is only about a tenth of their work on Clutch. Their site lists manufacturing and industrial verticals, but the named SEO results we found are all in software and tech.
Ask them on the call: Which B2B client outside software have you grown through SEO, and what happened to their pipeline?
2. PipeRocket Digital
Best for: B2B software, fintech and security teams that need SEO reported as pipeline
We’re PipeRocket Digital, and we work with B2B software, fintech and security companies. Technical SEO, content and AI search sit on one team, and every program reports into the pipeline view your leadership already looks at.
We map every query by who in the buying committee is searching and what they need at that stage, then build the comparison, alternatives, use-case and integration pages that bring in demos. On the technical side, we cover JavaScript rendering, log files, crawl budget and multi-region setups.
Reporting is connected to your CRM, so you see MQLs, SQLs, pipeline influenced and CAC payback by page type from week four. A senior-led pod owns the account, so the people you meet on the sales call are the people doing the work.

|---|---|
| Location | Chennai, India (US delivery) |
| Founded | 2023 |

What clients say: A cybersecurity platform that hired us for SEO and content wrote on Clutch that “their standout strength was their exceptional SEO expertise, coupled with strong execution capabilities” (source).
Think twice if: you’re a manufacturer or industrial supplier, because our work is in B2B software and tech, so OuterBox, Straight North or Orbit Media Studios will fit better. We also turn down ecommerce, local and consumer work, and we’re younger than most agencies here (founded 2023).
Ask us on the call: Which pipeline numbers will you report in month one, and where do they come from in our CRM?
3. OuterBox
Best for: Manufacturers, distributors and B2B ecommerce with large catalogs
OuterBox is an Ohio agency founded in 2004, with more than 250 in-house, US-based staff across SEO, paid media, development and CRO. Their B2B work is aimed at manufacturers, distributors and B2B ecommerce, for clients like Weiss-Aug Group, A&C Plastics and 1 EDI Source.
On a catalog site, they handle the parts most SEO agencies avoid: category structure, rules for which SKU and variant pages get indexed, product schema, part-number search and the paths buyers take to request a quote.
Reporting pulls in GA4, Search Console and the stage data from your CRM, with MQL, SQL, quote and closed-won definitions agreed up front. Their own tool, Loop Analytics, records the source of every lead, and conversion testing on forms, calls and booking paths is part of the work.
| Detail | OuterBox |

| Location | Copley, OH |

What clients say: A wire and cable distributor wrote on Clutch that “they’ve taken the time to understand our business, our industry, and what we’re trying to accomplish” (source).
Think twice if: you want the same people on your account for years, because some Clutch reviewers mention team changes that meant bringing new people up to speed.
Ask them on the call: Which manufacturer’s quote-request pages have you built, and how did you track the quotes they brought in?
4. TripleDart
Best for: B2B software companies that want vendor-comparison pages and AI search
TripleDart is a Plano, Texas agency that works as a go-to-market partner for B2B software companies like Glean, Airbase and Signeasy. Named senior leads run the SEO and AI search practice, with calls every two weeks and a shared Slack or Teams channel.
Their B2B program spends the first month mapping your ideal customer and buying cycle, then builds the pages buyers use to check vendors: comparisons, alternatives, use cases, case studies and FAQs. AI search gets its own audit and a 30-day plan, with citations tracked every month.
Reporting covers demos, trials and SQLs each month, with multi-touch attribution in GA4 that can plug into your CRM.
| Detail | TripleDart |
|---|---|
| Location | Plano, TX |

What clients say: A financial services company that hired them for SEO and content wrote on Clutch that “what impressed me most about TripleDart was their strong focus on results and execution” (source).
Think twice if: you want a long review record before you sign, because all eight of their Clutch reviews are from 2026.
Ask them on the call: Which vendor-validation pages would you build for us first, and which buyer in the committee is each one for?
5. Omniscient Digital
Best for: Established B2B software brands that measure content in pipeline dollars
Omniscient Digital is an Austin, Texas agency that works with B2B software companies, for clients like Smartling, Teambridge, Jasper and 360Learning. Their engagements are scoped around how much revenue content brings in, rather than how much traffic it gets.
They build strategy from buyer, voice-of-customer, product and competitor data, then decide page by page what to refresh, merge or retire. Their “barbell” approach pairs high-intent pages with a smaller number of big, authority-building pieces.
Technical SEO, digital PR, link building, CRO and AI search each run as their own service line. Their case studies report results in qualified pipeline, and full-service engagements start at $120,000 a year.
| Detail | Omniscient Digital |
|---|---|
| Location | Austin, TX |

What clients say: An AI-powered software platform that hired them for SEO and AI search wrote on Clutch that “their level of industry expertise, experimental approach, and the quality of the deliverables are impressive” (source).
Think twice if: you’re early stage or outside software, because the $120,000 floor fits established software brands.
Ask them on the call: Which pages would you refresh, merge or retire on our site first, and what pipeline do you expect from each?
6. SimpleTiger
Best for: B2B SaaS that wants month-to-month terms and CRM revenue reporting
SimpleTiger is a Sarasota, Florida agency founded in 2006 that works with B2B and B2C SaaS companies like Invoca, Segment, Gainsight and Jotform. Every package gets a client account manager, a team of three to six specialists and a shared Slack channel.
Their process starts with a strategy session and roadmap, then gap fixes within 30 days and the first content and links in month one. They build commercial, integration and comparison pages, earn links through digital PR, and run AI search inside the same program.
Their pipeline packages report revenue tied to your CRM, with attribution built in. Contracts run month to month, and each package starts at 5% of your revenue or funding, so the fee scales with your company.

RevenueZen is a Portland, Oregon agency where SEO is the only thing they sell, for B2B clients like Expensify, Bloomfire and Lightyear. Their work reaches past software too, into professional services, financial services, renewable energy and supply chain.
The program runs in five steps: analyze, grow, expand, validate and refine. Content comes from interviews with your own subject experts, and they build bottom-of-funnel solution pages, run technical audits and earn links through digital PR and linkable assets.
In the validate and refine steps, they go into your CRM and sales data to track MQL-to-SQL rates and deal velocity. Pricing is published, from $3,000 to $15,000 a month, and contracts can run month to month.
| Detail | RevenueZen |

They plan each site five to ten years ahead, based on demand and competition, and then build new pages for search and conversion. Technical SEO, landing page work, link building and copywriting written for both SEO and conversion all come from the same team.
Because they design and build websites too, SEO and the site itself move together, which helps when a redesign is coming. Website optimization starts at $10,000 a month, month to month.

12. Virayo
Best for: B2B software companies that want to show up in AI answers and on review sites

Their own Virayo AI portal tracks your visibility across ChatGPT, Claude, Gemini and AI Overviews every week. Engagements start at $7,500 a month for an initial six months, then go month to month.

They build a six-month SEO and AI search roadmap, then publish and update content at volume, refreshing 20 to 60 pieces a quarter through their own system. Their designers make the visual, linkable assets their content is known for.
They run full AI search optimization across ChatGPT, Claude and AI Overviews, and their team wrote a book on it. Technical SEO is done as needed, and results are reported as traffic value.

B2B SEO for Software vs Manufacturing and Industrial Companies
B2B SEO works very differently for a software company and for a manufacturer, and most agencies are strong at only one of them. On this list, OuterBox, Straight North, Orbit Media Studios, Victorious and Sure Oak show industrial and manufacturing results. Almost everyone else works mainly with software.
Here’s where the two usually differ:
| What differs | B2B software | Manufacturing and industrial |
|---|---|---|
| Who searches | Founders, marketing and ops leads, IT and security reviewers | Engineers, buyers and procurement managers |
| What they search for | “[category] software”, “[competitor] alternatives”, integration and use-case searches | Part numbers, specs, materials, compliance standards and “[process] services near me” |
| Pages that win | Comparison, alternatives, integration and use-case pages | Product and category pages, spec sheets, capability and industry pages |
| What counts as a conversion | Demo, trial or sign-up | Quote request, spec download or a phone call |
| Technical work | JavaScript rendering, app and docs subdomains | Catalog structure, SKU and variant indexing, faceted URLs |
| Agencies on this list | Directive, PipeRocket, TripleDart, Omniscient, SimpleTiger, RevenueZen, Stratabeat, Virayo, Grow and Convert, Siege | OuterBox, Straight North, Orbit Media Studios, Victorious, Sure Oak |
If you sell both, like an industrial company with its own software, ask each agency for a client that looks like yours before you compare anything else.
What Should a B2B SEO Agency Report?
A B2B SEO agency should report how organic search turns into leads, pipeline and closed revenue, alongside the rankings and traffic that lead there. If the report stops at traffic, nobody can tell whether the work is paying for itself.
Here’s what to expect in a good monthly report, and what should worry you:
| Metric | What it tells you | Red flag |
|---|---|---|
| Rankings on bottom-of-funnel searches | Whether you show up when buyers are close to a decision | Only broad, high-volume keywords tracked |
| Organic leads by page | Which pages bring in demos, quote requests and calls | Leads reported as one total, with no page breakdown |
| MQLs and SQLs from organic | Whether those leads are the right companies | No check against what sales accepts |
| Pipeline and closed-won from organic | What SEO adds to revenue, from your CRM | “We can’t see your CRM” |
| Cost per opportunity | Whether SEO is cheaper than your other channels | No comparison with paid search or outbound |
| AI answer citations | Whether ChatGPT and AI Overviews mention you for your category | Mentions counted with no list of the questions checked |
Sales cycles are long, so ask how they attribute pipeline to SEO when a deal closes months after the first visit.
How Much Does a B2B SEO Agency Cost?
B2B SEO usually costs $3,000 to $7,000 a month with an agency, $10,000 to $15,000 for an in-house team, and $7,500 to $10,000 for a hybrid setup, according to our B2B SEO guide. Agencies working with larger sites or more markets charge more.
The agencies on this list price in different ways, and the contract terms vary as much as the fees:
| Agency | Published price | Terms |
|---|---|---|
| RevenueZen | From $3,000/mo, tiers up to $15,000 | Month to month, discounts on 6 or 12 months |
| PipeRocket Digital | From $5,000/mo | 3-month minimum, then rolling |
| TripleDart | From $5,000/mo | No long-term commitment |
| Victorious | $6,000 to $35,000/mo for most B2B clients | 12-month term preferred |
| Virayo | From $7,500/mo | Six months, then month to month |
| Stratabeat | From $8,000/mo, $15,000 to $21,000 for the middle tier | No long-term contract, 30 days’ notice after six months |
| Orbit Media Studios | From $10,000/mo | Month to month |
| Grow and Convert | From $10,000/mo | No 6- or 12-month contract |
| SimpleTiger | 5% of revenue or funding | Month to month |
| Omniscient Digital | From $120,000/yr | Not stated |
Directive Consulting, OuterBox, Straight North, Sure Oak and Siege Media don’t publish prices. Before you compare quotes, forecast the pipeline SEO should bring in, so you know what a fair budget looks like.
Questions to Ask a B2B SEO Agency Before You Sign
These are the questions that separate an agency that’s done B2B work from one that’s pitching it:
- Your industry: Which client like us, in our industry and at our size, have you grown, and can we talk to them?
- The buying committee: Which people in our buying committee would each page be written for?
- Pipeline: Which pipeline numbers will we see, and from which system?
- AI search: Who handles AI search, and how do you track it? Ask them to run five of your category questions in ChatGPT and Perplexity on the call.
- Exit terms: What’s the notice period, and what do we keep if we leave?
And these are the red flags that should end the conversation:
- Guaranteed rankings: nobody controls Google’s results, so a guarantee means they’re promising something they can’t deliver.
- No client in your industry: an agency that has only worked with software will be learning manufacturing on your budget, and the reverse is true too.
- Traffic-only reporting: if their reports show traffic and keyword counts with nothing tied to leads or pipeline, you won’t be able to defend the spend.
