1. Perceptric (Best for BOFU-focused, expert-led B2B SEO content)

Perceptric is a B2B SEO and content marketing agency built from firsthand experience seeing the need of better content in the B2B world.

Too often, we saw the same patterns repeat:

1. Some B2B marketing managers (unfortunately) don’t trust SEO, often because there’s so much low-quality or conflicting information about it. When they’re unsure about how B2B SEO really works, they avoid using it, and without their support, the company can’t make SEO an effective channel.
2. On the other side, some marketers go all-in on SEO and forget the basic reason people click on a page: they want useful information. Pages created only to rank, without offering real value, can actually hurt the brand, especially when the audience includes technical users. They are smart, and they can spot fluff content from miles away.
3. Teams working on technical products often misunderstand their SEO potential. They see low search volume in search queries and assume there’s no real opportunity to drive leads. This can delay SEO until competitors have already invested heavily, making it harder to catch up later.
4. And finally, many SEO agencies lack experience with technical subjects. They may not fully grasp search intent, and even when they do, they often miss the nuance required for financial topics. A CFO researching a problem needs very different content from a random guy picking a simple personal finance app. Without that understanding, agencies end up producing content that misses the mark.

That’s exactly why I started Perceptric: a B2B SEO and content marketing agency purpose-built for technical products and services like fintech. No matter how niche you are, we are here to help you create content that actually aligns with buyer intent and long-term brand positioning.

How Perceptric approach B2B SEO differently

I use what I call the Knowledge-Narrative model when it comes to B2B SEO. It’s how the best content teams operate (think: HubSpot, Notion), and it’s the same playbook I apply for our clients and for Perceptric itself. When Knowledge content and Narrative content is combined and written well, you get the best of both worlds:

Model	Pros	Cons
Knowledge	– Drives consistent SEO traffic – Evergreen content compounds over time – Great for product education and acquisition – Scales well with small teams	– Slower to show results – Less engaging on social – Can feel impersonal without human voice – Requires keyword research and SEO rigor
Narrative	– Builds brand voice and trust – Great for social and email engagement – Flexible and timely – Showcases thought leadership and POV	– Needs strong distribution – Less SEO value over time – Content decays quickly – Harder to scale without a team or audience

Perceptric also follows several key principles when creating content:

• Our writers come from real technical backgrounds, through training, experience, or both, so we can produce content that advanced users actually trust.
• We take time to understand your product by talking to your team and customers, watching demos, reading docs, and trying the product ourselves.
• We bring your technical stakeholders into the process just enough to keep them comfortable and confident in the content, without taking too much of their time.
• You get a team that can scale smoothly, adjust to changes on either side, and keep the work moving without interruptions.
• You can start quickly because our team is already set up, aligned, and ready to deliver real results within the first month.

So, if you’re looking for a strategic B2B SEO partner that aligns with pipeline goals, Perceptric belongs at the top of your list. Here are the results we measure for you:

• Generating leads or MQLs attributable to content published
• Increasing the number of sign-ups or other conversion events
• Increasing revenue
• Landing high-value clients and contracts through inbound requests

Since 2009 they have helped B2B software and technology clients dominate competitive industries in verticals including insurance, finance, legal, healthcare, logistics, shipping, manufacturing, network security, cloud computing, and investor relations.

4. First Page Sage (Best for BOFU-led SEO for B2B companies)

First Page Sage is another good B2B SEO agency with solid understanding of the long sales cycle. From a quick analysis of First Page Sage’s SEO strategy, I can see that they also use the BOFU-led approach for their content production, and they’re using it really well. They know how to target the keywords with highest revenue potential for your brand.

One of their notable clients is Cadence Design Systems Inc, a leading electronics design automation (EDA) software provider serving the electronics industry. First Page Sage helped them compose SEO-driven content written by electronics engineers to be published on the company’s PCB Resources page.

This shows they have a strong team with technical expertise to help you achieve the same results:

First Page Sage also offer Thought Leadership content services for B2B clients. They understand that thought leadership is what genuinely drives buyer decision in this space. To achieve this, they hire experienced writers who are intimately familiar with writing for B2B companies so that they can effectively ghostwrite thought leadership for their clients.

• Services offered: Thought-leadership and SEO content for B2B, keyword dominance, high-frequency publishing
• What makes them stand out: Solid understanding of SEO in the B2B space
• First Page Sage pricing: They don’t list packages publicly, but their article on SEO pricing research tells you the ballpark. For First Page Sage, premium, custom SEO pricing typically starts at $3,500-$7,500/month for content-focused plans and escalating to $12,000+/month for full-service, strategy-driven packages.
• It’s a great fit for: B2B companies needing integrated demand-gen, PR, brand authority, and content under one roof.

5. Grow and Convert (Best for long-form SaaS SEO content that ranks converts.)

Grow and Convert is a content marketing agency best known for its “Pain-Point SEO” framework. Pain-point SEO is a methodology designed to prioritize high-intent keywords that drive signups and demos instead of vanity traffic.

They emphasizes a lot on attribution with tutorials and consulting around GA4 setups that let teams prove how content contributes to trials, demos, and closed revenue. I personally like the way Grow & Convert invests into the content creation process. They set the bar high for each and every single piece of content they write.

• Services offered: Long-form SEO content, conversion-focused strategy, keyword research
• What makes them stand out: Their inbound strategy centers on high-intent content that brings in buyers already researching problems, not top-funnel traffic that never converts.
• Grow and Convert pricing: Their content packages are pretty straightforward. The public plans land at roughly $10,000 and $15,000/month. PPC is an optional add-on that runs about $3,500/month on top.
• It’s a great fit for: Companies that want content SEO built specifically to drive qualified leads, not vanity traffic.

Website: Grow and Convert

6. Ironpaper (Best for B2B inbound marketing)

Ironpaper is a B2B growth agency that helps SaaS companies attract organic leads through clear messaging and useful content. They are a full-service agency with services spanning across organic growth, paid ads, ABM, content, to web development. Anything you need to grow your B2B SaaS, Ironpaper has.

• Services offered: B2B demand generation, content-driven SEO, revenue operations
• What makes them stand out: They deeply understand the challenges of the long and complex B2B sales cycle, so they tailor their strategy to engage with your audience throughout the entire buyer journey. They also bring their subject matter experts to the table when your product is too complex for generic content shops to communicate effectively.

• Ironpaper pricing: Pricing is fully custom here. Everything is positioned as a tailored B2B growth program, and they don’t publish a rate card anywhere. From what I can tell, you only get numbers after a strategy call, and there’s no reliable public minimum I can point to.
• It’s a great fit for: B2B companies with complex sales cycles that need tight demand-gen, ABM, and revenue-focused marketing.

Website: Ironpaper

7. Refine Labs (Best for Demand Gen content marketing in SaaS)

Refine Labs is a B2B demand generation agency best known for pioneering shifting the focus from lead volume to revenue impact in B2B marketing. Founded by Chris Walker, the agency emphasizes a no-bullshit approach to inbound demand generation.

The idea behind Refine Labs is that:

• There is a ‘cognitive dissonance’ of some kind in the way that most marketing and sales departments work together. Usually, marketers try generate as many leads as possible (with an ebook) then pass all those leads to sales. But someone inserting their email to download an ebook is in no way an indication they want to buy from your company. That’s only overloading the sales reps with very low-quality leads.
• Instead, he believes that the best lead is inbound. A buyer that knows what you do, and comes to you when they are in need of your services. To do that, you need brand awareness. You want to be the credible, top-of-mind company when anyone needs a service like yours so you are the first one they think of.

Therefore, Chris advocates for a content-led approach to demand gen. His agency helps you produce content that helps your customers in many parts of their work. Building credibility is 98% of the hard work, so that the remaining 2% will happen when the time is right.

What I like about Refine Labs is their knowledge platform for B2B demand generation and GTM teams, called The Vault. It has a lot of good information about modern demand-gen strategy (versus traditional lead-gen), revenue forecasting & planning, and measurement frameworks. Refine Labs also has a lot of great video resources on data attribution topics on YouTube that you can check out:

• Services offered: marketing strategy consulting, content marketing, performance marketing, revenue forecasting & planning
• What makes them stand out: they have a unique approach to Demand Gen that challenges the way too many marketers are doing wrong.
• Refine Labs Pricing: custom

8. Codeless (Best for scaled SEO content that drives recurring SaaS traffic.)

Codeless is a high-volume content agency that helps SaaS companies scale SEO content quickly.

They’re behind the tremendous growth of Monday.com. Their secret is high-volume content targeted at very specific topics to win SEO topical authority. All content written by Codeless is powered by a lot of research.

If you want to produce content at scale, quickly, Codeless is the ultimate choice.

• Services offered: SEO content at scale, editorial operations, keyword-driven production

9. Omniscient Digital (Best for SEO, GEO, and content tied tightly to pipeline)

Omniscient Digital is a strategic inbound agency that helps you connect SEO, content, and lifecycle marketing to revenue.

Their leadership team has led initiatives in those exact roles at big B2B SaaS companies like HubSpot, Shopify, and Workato and run large-scale editorial processes at companies like Backcountry and Clearlink, so you can rest assured that they will apply that well-earned knowledge into your campaigns.

Their inbound programs emphasize the importance of organic growth. They’re also highly data-driven, and all campaigns leverage cross-functional expertise to prioritize the small percentage of actions that have the largest impact on your revenue.

They have worked with the big clients like Jasper or HotJar:

• Services offered: SEO and content strategy that drives pipeline, programmatic SEO, technical SEO, GEO, link building, content production
• What makes them stand out: Their analysts prioritize topics based on revenue and ignore vanity keywords, so inbound actually contributes to pipeline. They also integrate deeply into your team so they can look at the bigger picture of how their work fits in with (and potentially augments) other channels and campaigns you’re building.
• Omniscient Digital pricing: Omniscient Digital runs fully custom programs.
