ClearBrand built this comparison. We included ourselves and named the agencies we send people to when they fit better.
A B2B SEO agency earns its fee by growing pipeline. Rankings and traffic support that goal, but revenue matters most. The seven agencies here each serve a different kind of company well.
| Agency | Best for | How they work |
| ClearBrand | B2B and SaaS teams on Webflow that want site, SEO, and AI search as one system | Webflow-only retainer and builds |
| First Page Sage | Thought-leadership content and AI citations in complex B2B | Content-led retainer |
| Directive Consulting | Mid-market and enterprise SaaS that want SEO inside a full-funnel program | Performance retainer across channels |
| Percepture | Enterprise B2B with long, regulated sales cycles | PR-led SEO and GEO |
| OuterBox | Technical and B2B ecommerce sites with large catalogs | Full-service SEO retainer for ecommerce |
| Obility | B2B tech and SaaS that want paid and organic under one roof | B2B-only search and demand gen |
| Altitude Marketing | Manufacturers and life science brands with technical products | Integrated B2B marketing |
How we evaluated each agency
We scored each agency on five verifiable points.
- Named B2B clients and results. Real case studies, not a footnote.
- Reporting tied to revenue. Connection between organic work and closed deals.
- AI search capability. Proof of clients cited in AI answers and schema work explained.
- Transparency. Clear pricing and a named account team from the start.
- Fit honesty. Clear statements about what they do not serve well.
You can ask any agency for the same proof.
ClearBrand: Best SEO Agency for B2B and SaaS teams using Webflow
We built ClearBrand for B2B and SaaS teams that want their website and search program as one system.
We work only in Webflow.
Most agencies treat the site and search work as separate jobs. We build pages, schema, and content together. Technical SEO and AEO become part of the build.
Our clients show revenue results. We worked with KleerCard, a fintech competing against larger players. Within two months, KleerCard appeared in Google’s AI Overviews.
After about six months, roughly half of their new customers came from organic search. You can read the details on our case studies page.
We report on money, not impressions. We track which leads come from organic search, which close, and the revenue they generate.
We focus on Webflow. Companies that run on WordPress or need enterprise PR woven into search often find a better fit with another agency on this list.
For SaaS teams and larger Webflow builds, our guide to Webflow enterprise SEO covers the architecture decisions that matter before launch.
First Page Sage: Thought-leadership content and AI citations
First Page Sage builds authoritative editorial content for complex B2B companies. Their founder, Evan Bailyn, helped define generative engine optimization. The agency focuses on content that earns both Google rankings and AI citations.
They have worked with Microsoft, Salesforce, and SoFi. Their experience runs deep in SaaS, medtech, and manufacturing.
This approach fits companies where buyer trust depends on subject-matter depth.
Companies that need mostly technical fixes or paid media and CRO in one program often look to Directive or Obility instead.
Directive Consulting: Full-funnel SaaS growth
Directive is a performance agency built for technology companies. Their Customer Generation method ties SEO, paid media, and CRO to pipeline and revenue.
They report more than a billion dollars in client revenue over the past decade. Clients include Cisco, ZoomInfo, and Gong.
Third-party roundups place their retainers in the five-figure-per-month range. This fits funded mid-market and enterprise teams.
Smaller budgets or single-channel needs often call for a narrower partner.
Percepture: Enterprise B2B with complex sales
Percepture serves companies with long sales cycles, technical buyers, and high proof requirements. They connect digital PR to SEO and GEO so earned media and rankings reinforce each other.
Founded in 2004, they work across life sciences, telecom, data centers, and aerospace and defense. Their team skews senior.
This matters when a single bad article can stall a multi-million-dollar deal.
Their work suits companies with long sales cycles and high stakes. Smaller B2B teams looking for leads in the next quarter often start with a different approach.
OuterBox: Technical and ecommerce-heavy B2B
OuterBox has run SEO for more than twenty years with a US-based, in-house team. They handle complex catalogs, large product taxonomies, and the technical SEO that breaks on big sites.
They publish hard numbers on client work, including organic traffic gains above 400 percent on B2B accounts.
Their strength shows on sites where SKUs, gated content, and product architecture complicate the search picture.
Companies that sell a single service with a small site often find this depth unnecessary. Large or ecommerce-adjacent B2B sites benefit from it.
Obility: Paid and organic under one roof
Obility works with B2B tech and SaaS companies only. No B2C accounts pull focus. They run SEO alongside paid search and social, tied together with deep CRM and attribution work.
They track campaigns through to closed-won revenue. This gives marketing leaders a clear read on what drives deals.
Their fit is strongest for mid-market SaaS teams with a real internal strategy and a paid budget to manage.
Companies that want SEO handled in isolation or need site design help often choose a different partner. Consolidated paid and organic with clean attribution makes them a strong B2B-only option.
Altitude Marketing: Technical and life science brands
Altitude Marketing runs integrated B2B marketing for complex industries like life sciences, manufacturing, and technology. They pair strategy with execution and translate technical products into positioning that earns leads.
Their work fits companies whose buyers need education before they consider a vendor. SEO sits inside a broader marketing program rather than standing alone.
Companies that want a search-only specialist often need less than a full agency. Technical manufacturers that want one team handling positioning, content, and search find a good match here.
How to choose your shortlist
Start with the work you need done, not the agency.
A freelancer fits a narrow, well-defined task. An in-house hire fits a company ready to own SEO as a long-term function. An agency fits a company that needs a full team and a strategy without building one.
Many companies run a hybrid. They keep one internal person to coordinate and hand strategy and production to an agency.
Watch for a few patterns that should send you the other way.
Guaranteed number-one rankings go against what Google warns about. Reports full of impressions and rankings with nothing about leads or revenue miss the point. A senior pitch followed by junior delivery once you sign creates problems. Prices under $500 per month rarely buy real work.
Ask each agency to show a client cited in an AI Overview or ChatGPT answer. Ask them to explain how they handle schema. Vague answers there signal trouble in 2026.
What B2B SEO costs
Most B2B SEO agencies charge a monthly retainer. Ahrefs survey data puts the agency average at $3,209 per month. Freelancers average near $1,348. Hourly rates fall between $75 and $150.
Clutch review data shows an average monthly cost around $3,199 over a typical twelve-month engagement. Competitive national B2B campaigns often run higher as scope grows.
ClearBrand publishes its numbers. Our AI SEO retainer starts at $4,999 per month (which is fairly standard for mid-market B2B SEO). A new Webflow site starts at $14,999.
Most competitors quote on request, so ask for a number early.
How long B2B SEO takes
Early ranking movement usually shows in two to three months. Meaningful lead growth tends to arrive around six to nine months. Results then compound.
Treat it as a twelve-month investment.
Some cases move faster. KleerCard started closing new business from search inside a month.
Agencies that guarantee fast, certain results generally shouldn’t be trusted. SEO is a competition, not something you can guarantee. Can you imagine an NBA team guaranteeing they’d win? Me neither.
Frequently asked questions
How much does a B2B SEO agency cost?
Most charge a monthly retainer. Ahrefs survey data puts the agency average near $3,209 per month. Clutch data lands close at about $3,199. These numbers include smaller companies and industries.
Competitive national B2B campaigns commonly run higher. ClearBrand’s own AI SEO retainer starts at $4,999 per month, which is fairly standard.
How long does B2B SEO take to work?
Early ranking movement appears in two to three months. Meaningful lead growth usually arrives around six to nine months. Plan for a twelve-month commitment.
Is a B2B SEO agency worth it?
It depends on your starting point and your patience. In B2B, one won customer can repay a year of SEO because deal sizes run large.
The Content Marketing Institute’s 2025 research found 74 percent of B2B marketers say content marketing helped them generate demand and leads.
Should I hire an agency, a freelancer, or build in-house?
In-house gives you the most control. One hire rarely covers technical work, content, and links at once. A freelancer fits a single narrow task.
An agency brings a full team from day one. Many companies run a hybrid with one internal coordinator.
What should I look for in a B2B SEO agency?
Look for named B2B clients, reporting tied to revenue, real AI search capability, transparent pricing, and a named account team. Ask who writes your content and who runs your strategy.
Get the names before you sign.

The right B2B SEO agency grows your pipeline. Your pick depends on your platform, your sales cycle, and whether you need one task or a whole system.
If you run a B2B or SaaS company on Webflow and want the site and search built together, ClearBrand fits. When another agency on this list matches your needs better, we say so.
