10 Best B2B SEO Agencies to Scale Your Pipeline in 2026

I have been doing SEO for B2B companies for 11 years.

In that time I have helped generate over $80 million in revenue across bootstrapped and funded companies.

I started as the second marketing hire at a bootstrapped SaaS, where the only metric that mattered was trials generated this month. Not traffic. Not domain rating. Trials.

That experience shaped how I evaluate every other SEO agency on this list.

Because here is the truth: most B2B SEO agencies are still running a 2016 playbook. Keyword research, cheap content, some links, hope to rank.

It works well enough to keep clients around for a few months. It almost never moves revenue.

The agencies on this list are different.

They have each built something that connects SEO to actual business outcomes. Some are stronger on content. Some are stronger on technical.

Some are ahead on AEO and AI search. I will note the differences so you can find the right fit for where your company is right now.

How B2B SEO Has Changed

SaaS SEO in 2016 and B2B SEO in 2026 are two different games.

When I started in 2015, all I needed to do was:

1. Keyword research – find high traffic, low competition keywords.
2. Content brief – create an outline for the writer.
3. Hire a cheap writer – pay someone who has no idea what they're talking about 10 cents a word.
4. Scale up – repeat.

But today, buyers are more sophisticated and they know when they are reading generic content.

AI Overviews are consuming the top of the SERP. Clicks to the number one position are down significantly where AI answers appear. And buyers are increasingly starting their research in ChatGPT and Perplexity, not Google at all.

The companies winning at B2B SEO in 2026 are doing three things the old playbook never required:

• Creating content with a real point of view, built from interviews with subject matter experts and sales teams, not from reading competitor posts.
• Building brand presence off-page through podcasts, YouTube, guest posts, listicles, and brand mentions that tell AI systems who they are and what they solve.
• Measuring revenue, not vanity metrics. If organic is not driving trials, demos, and MRR, the strategy is not working, regardless of what the traffic chart looks like.

4 Factors to Look for When Hiring a B2B SEO Agency

Factor 1: Buyers are more sophisticated

There was a stretch of time, and maybe we are still in it, where buyers knew that the page one results were simply SEO content designed to rank. The type of homogenized content outsourced to a writer with no domain knowledge.

This turned off the most sophisticated buyers. The ones most likely to actually buy your product.

The best agencies today create content that ONLY your company can create. Content that reflects a real point of view, real customer language, and real product knowledge.

Factor 2: Be recommended, not just ranked

We are moving into an era where if your SaaS is not recommended by LLMs, it is going to be hard to compete. And no, AEO is not just SEO done well. It is part of it, but not all of it.

Your agency needs a strategy to get your SaaS on the shortlist of tools that LLMs recommend. This is done through the way content is created, the way link building is done, and how the brand is built off-page.

Factor 3: Create demand

SEO used to be about fulfilling demand. Someone searched for your product, and you just needed to appear. But space in the SERPs is becoming more limited. And even if you hit position one, you are not getting the same click-through rate as you once did.

As an SEO agency, we are now responsible for creating demand, not just capturing it. By getting you in front of more audiences through podcasts, YouTube, guest posts, and brand mentions, so they can discover and share your product.

Factor 4: Revenue is the only metric that matters

For the longest time, SEO agencies used traffic as their key metric. But now agencies are under scrutiny from finance teams and boards. You need to justify the cost.

Is revenue going up? If yes, your SEO is working. If not, it is not. Everything else is noise.

The 10 Best B2B SEO Agencies in 2026

1. Content Guppy

We have spent the past five years building, adjusting, and modifying a B2B SEO agency designed to help SaaS companies increase MRR.

Like I mentioned, the way we did SEO back in 2015 will not work in 2026. Here is how we have adjusted our system to address the factors we discussed above.

1. Create content for more sophisticated buyers

Instead of creating a content brief, shipping it off to a writer who has no idea what they are talking about, and publishing, we create content with your point of view.

We do this two ways:

Interviews with SMEs. The first thing we do is interview subject matter experts within your company so we understand your point of view on a particular topic. The goal is to create content that ONLY your company can create. We want to know why your SaaS does what it does, why it exists within the marketplace, and what you want your customers to know about the product.

Interviews with sales team and customers. We also interview your customers and sales team. This is where the real data comes from. Straight from the trenches. A few of the questions we ask:

• Why did your customer hire your SaaS?
• What features are most important?
• What integrations are the most used?
• Why did they switch from what they were doing?

2. Get recommended

We used to simply create content that was regurgitated research. We added nothing new to the ecosystem. And sadly, most agencies still do this today. They throw a brief into AI, or give it to a cheap writer, and call it a day.

But this is not how content gets recommended in an AI search world.

We are not just an SEO agency that bolted on AEO services when it became the thing to do. We rebuilt our entire process from the ground up. From how we create content, through our interview process, to how we promote content.

Before, we used to build links, rank the content, and be done. But now we get you on podcasts and YouTube channels so you can share your POV.

We write guest posts promoting your SaaS. And we get you brand mentions on high-authority sites. This is how you dominate in the SERPs and get your SaaS shortlisted in LLM recommendations.

3. Create demand

SEOs can no longer just fulfill demand. You cannot just rely on people searching Google for your keywords, product, or company.

At Content Guppy, we create demand by getting our clients in front of other people’s audiences and sharing their product and point of view far and wide.

This includes getting interviewed on podcasts and YouTube channels, guest posts on popular blogs, newsletter features, and brand mentions.

4. Revenue is all that matters

How we hold ourselves accountable is by creating content that converts traffic into trials and demos. You will see content on your site and know that it is producing revenue, not just increasing traffic.

Notable clients: Superhuman, Time Doctor, Kickbox, V2Cloud

2. Grow and Convert

Grow and Convert coined the term Pain Point SEO back in 2018 and have been building their whole methodology around it ever since. The idea is straightforward: B2B companies should prioritize high buying-intent keywords, the ones buyers search when they are actively evaluating solutions, rather than chasing high-traffic educational content that rarely converts.

Their content research process is done right. They conduct direct interviews with client sales teams, product teams, and customer success teams to surface the actual language buyers use. All content is human-written. And they track conversions at the page level, so clients can see which pieces are driving demos and signups, not just traffic.

If you are comparing Grow and Convert to Content Guppy, the key difference is what happens beyond the content. Content Guppy runs podcast placements, listicle guest posts, and brand mention campaigns to build the off-page signals that determine whether AI recommends you. Grow and Convert is primarily a content and link building agency. Both approaches are valid. The right choice depends on whether AI visibility is a priority for your program.

Key services: SEO content strategy, content writing, link building, analytics and conversion tracking

Notable clients: Segment, Okta, Outpost

3. Omniscient Digital

Omniscient Digital helps B2B SaaS businesses grow by improving their online content. Founded by former senior marketers from HubSpot, Shopify, and Workato, their client-centric approach involves understanding conversion goals, building a tailored SEO strategy, implementing the plan, and making improvements based on data.

Their consultative approach makes them popular across established companies. They follow what they call the Barbell Content Strategy: 90% product-led content that explains the product value proposition, and 10% buzzworthy content that attracts backlinks, attention, and social shares. Together both types combine to build topical and domain authority.

They have also invested meaningfully in GEO, their generative engine optimization offering. It is listed as a dedicated service rather than a marketing rebrand, which is a good sign. Their pricing is on the higher side, making them better suited to funded companies than bootstrapped ones.

Client quote: “We’ve published over 100 articles which has also directly led to new business. We’ve created over $4M in annual recurring revenue through our blog.” – Austin Distel, Jasper

Key services: SEO strategy, content creation and optimization, link building, technical SEO, GEO

Notable clients: Hotjar, Jasper, Asana

Pricing: Full-service from $10,000/mo. Strategy from $15,000.

4. Optimist

Optimist is one of the more credible AEO practitioners in the B2B SEO space right now. They have published actual case studies showing revenue from AI search. Not just brand mention increases or AI visibility improvements, but dollars in the pipeline from ChatGPT, Perplexity, and Claude referrals. That is rare, and it matters.

Their CORE framework integrates AEO and traditional SEO from the start, rather than treating them as separate programs. They also cover the full funnel: acquisition, activation, retention, revenue, and referral, which makes them unusual among content-first agencies.

Unlike other agencies on this list, they do not just focus on demand generation. They are content experts across all SaaS funnel stages.

Client quote: “Working with Optimist is fantastic. They collaborate seamlessly with our in-house SEO team and maintain the high quality we aim for.” – Ana Camarena, Semrush

Key services: AEO and SEO strategy, content production, digital PR, link building, analytics

Notable clients: Semrush, Superhuman, ZoomInfo, HelloSign

Pricing: From $2,500/mo for entry plans. Full-service from $10,000/mo.

5. Directive Consulting

Directive is one of the larger performance marketing agencies built specifically for technology companies. They approach SEO as a revenue channel, not a traffic channel, which puts them ahead of most agencies their size. They have built GEO into their service offering and invest heavily in research and development, which means their approach tends to stay current as the search landscape shifts.

Their pricing reflects their scale. They are a better fit for enterprise and well-funded mid-market companies than for growth-stage SaaS. But for the right company, the integrated SEO, paid media, and RevOps offering is genuinely difficult to replicate elsewhere.

Key services: SEO, GEO, content marketing, paid media, CRO, RevOps, video

Notable clients: Cisco, ZoomInfo, Gong, Uber Freight, Samsung

Pricing: Custom. Enterprise engagements typically from $20,000/mo.

6. Skale

Skale helps B2B software businesses grow by improving their presence on search engines. They have helped many companies achieve significant results: Rezi increased revenue by 176%, Holded saw a 450% jump in monthly signups, and Flodesk boosted free trial signups by over 2,000%.

Their approach balances short-term wins and long-term goals. Around 20% of growth comes from faster, easier wins that hit monthly targets while building for the future. The majority comes from harder, more valuable keywords that take more time. GEO is listed as a service, though it appears to be an integrated add-on rather than a core part of their methodology.

Client quote: “One thing that stood out to me when working with Skale is the reporting. It’s very clear when a link goes live, which makes it easy to track the impact.” – Kevin, G2

Key services: SEO strategy, content production, link building, GEO

Notable clients: Rezi, Moonpay, PicToChart

Pricing: Full-service from $4,000/mo

7. MADX Digital

MADX Digital is a revenue-first B2B SaaS SEO agency that delivers custom services spanning technical SEO, content writing, digital PR, link building, and Generative Engine Optimization for AI search platforms, including ChatGPT, Perplexity, and Google AI Overviews.

Their framework operates in seven structured steps: technical SEO audits, keyword and audience research, on-page optimization, content strategy, authority building, performance tracking, and iteration. They have dedicated service tiers for Seed, Series A, and Enterprise clients, which means they can serve companies at different stages without one-size-fits-all pricing.

Their client results are well-documented: Parcel Tracker grew from 1,000 to 45,000 monthly organic visitors under their management, and Postalytics scaled to 75,000 monthly visitors within 12 months.

Key services: SEO, GEO and AI search, content writing, digital PR, link building, technical SEO

Notable clients: MoonPay, Postalytics, Parcel Tracker, Veed.io, TitanHQ

Pricing: Available on request. Tiered by growth stage.

8. Siege Media

Siege Media specializes in content-driven SEO for B2B brands, combining high-quality content production with data-backed SEO strategies to drive measurable organic growth. Their strength is producing large, research-backed content assets that earn backlinks naturally, which compounds domain authority over time rather than relying purely on outreach-based link building.

In competitive B2B markets, that kind of authority building can move rankings in a way that individual link inserts cannot. They are not a heavy technical SEO shop. Their value is in editorial quality and content strategy. For B2B companies that have strong product stories but need help turning them into content that earns real organic authority, Siege is worth considering.

Key services: Content strategy, content production, digital PR, link earning

Notable clients: Zillow, Intuit, HubSpot

Pricing: Available on request

9. Virayo

Virayo has been specializing in B2B SaaS SEO since 2012 and has built a reputation for data-driven strategies tied to pipeline and ARR rather than traffic. They are also ahead of many agencies their size on AI search adaptation, with their lead strategist regularly publishing content on LLM visibility and how SaaS companies should adjust their strategies.

They offer technical SEO alongside content and strategy, and position themselves specifically for growth-stage software companies that need to generate qualified leads, not just grow organic sessions.

Key services: SEO strategy, technical SEO, content strategy, AI search visibility

Notable clients: Sprout Social, MYOB, Brandfolder, Truckstop

Pricing: Available on request

10. Quoleady

Quoleady helps B2B SaaS companies grow their visibility across both traditional search engines and AI-driven platforms. Their AEO offering includes LLM visibility audits, schema markup, llms.txt setup, and digital PR placements designed to get brands into high-trust publications that AI systems pull from.

They published a case study showing a 47.5% increase in booked meetings from AEO work. That is one of the more concrete outcome metrics I have seen from an agency in this space. They tend to work with mid-size B2B SaaS companies and have strong experience with European markets.

Key services: SEO strategy, content marketing, AEO and LLM visibility, link building, digital PR, technical SEO

Notable clients: Expandi, PandaDoc, monday.com, airfocus

Pricing: Retainers from $1,500 to $2,000/month

Which Agencies Have a Real AEO Strategy?

I wanted to see which agencies have a genuine AEO strategy rather than a rebrand. Here is what I found:

How to Choose the Right B2B SEO Agency

Now that you have read through these agencies, here are the questions to ask yourself when making a decision:

• What is my SEO budget?
• Does the agency have a genuine AEO strategy? How will they help you get recommended in LLMs?
• What approach will work best with my existing marketing team and current SEO efforts?
• How soon do I need to start seeing results?
• Do they measure success in revenue, or in traffic and rankings?
