Unlike B2C where buying decisions happen quickly, B2B buying journeys are incredibly complex.
Here’s a snapshot of that complex buying journey:
For products/services with complex buying journeys, SEO plays the role of product education. Your end goal is to show up when prospects are actively searching on Google for a solution to tell them that “Hey, our product is exactly what you need, here are 3 reasons why, book a demo with us today”.
It’s as simple as that. However, not many SEO agencies understand that. They chase after keywords that have absolutely no revenue value.
That’s why we’ve shortlisted only the best 10 SEO agencies that truly understand the complex buying journeys.

1. Perceptric (A B2B SaaS SEO agency that focuses on BoFu)
Okay, since I’m writing this article, I’ll take the opportunity to show you what makes Perceptric the right choice for your content programs.
Perceptric is an SEO/content marketing agency that help B2B products/services (fintech, retail tech, HR tech, health tech, manufacturing, and beyond) to build content engines that drive true business results.
Perceptric’s approach to SEO for complex products/services is pretty simple:
1. Perceptric starts at the bottom of the funnel
When someone is at the bottom of the funnel, they’re already comparing options and trying to make a decision. If you show up here with clear, helpful content, you meet people at the exact moment they’re looking for you.
If you’ve ever watched a deal stall because a prospect didn’t understand something, you know the pain. We create content at the bottom-funnel stage to do the heavy lifting for you: answering objections, clarifying differentiation, showing outcomes, making the “why you” much clearer.
Think of high-intent content like:
- [vendor] alternatives
- [solution] vs [solution]
- best [category] platforms for [industry/role]
- [vendor] pricing
- [vendor] reviews
- top [industry] providers
- [solution] for [specific workflow or department]
- [solution] ROI
- [service provider] case studies in [industry]
When you publish this kind of content, sales teams feel the impact right away. That’s exactly where the leads come from.
2. Perceptric brings technical expertise to the table
- 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 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

2. Grizzle (A SaaS content + PR agency)
Grizzle is a great content marketing agency for B2B and SaaS companies who want to accelerate their GTM outcomes.
Grizzle started as a simple digital PR company, but over time their clients realized that the quality of their content was quite good, so they want that content to be written for their own websites, and so Grizzle starts to offer content marketing services on their own. Fast forward a few years, you have a full multimedia content marketing agency that understands SaaS complexity.
- Services offered: content production, video production, content refreshing, content repurposing
- What makes them stand out: Their content-led lead generation system creates bottom-funnel assets that give SaaS companies direct paths to demo-ready leads.
- Grizzle pricing: Grizzle keeps things custom.

- 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
4. YesOptimist (A full-service content marketing agency)

Website: YesOptimist
5. Grow and Convert (A conversion-focused B2B SaaS content marketing and SEO agency)
Grow and Convert is a content marketing agency best known for its “Pain-Point SEO” framework and a BOFU-led approach to content marketing.
Pain-point SEO is a methodology designed to prioritize high-intent keywords that drive signups and demos instead of vanity traffic. Grow and Convert also emphasizes a lot on success attribution, so they offer consulting around GA4 setups to help teams prove how content contributes to MQLs and closed revenue.
I also 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.

First Page Sage is another SEO agency with strong proficiency in complex buying journeys. 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.

Website: First Page Sage
7. Wizard on Demand (A technical content agency with solid SEO understanding)
Wizard on Demand is a technology marketing agency that offers technical explainers/content, all at engineering-grade. If you have a deep-tech product targeting engineers/developers, an agency like Wizard on Demand is the perfect choice.
What’s even better is that they apply SEO best practices into every article they produce so that the content promotes themselves. It’s like having an SEO agency and technology marketing agency under one roof. Although they lean more towards content marketing than SEO, they understand the powers of SEO when marketing to an audience that usually hates seeing ads (and use ad blockers a lot).
- Services offered: Technical content writing, product-led content, developer documentation
- What makes them stand out: You get deep technical content that improves adoption and explains how your product actually functions.
- Wizard on Demand pricing: Typical engagements land in the five-figure range. Directories consistently show a minimum project size around $10,000, with most actual projects falling between $10,000–$24,999. They quote everything custom, so you end up on a call before they shape your retainer or project.
- It’s a great fit for: Technical software, dev-tools, and engineering-heavy products needing deeply technical, developer-friendly content.
- Perhaps not a great fit if: You need a high-output SEO content program without deep conversion focus or qualitative research.

Since 2009, they’ve helped B2B software and technology companies compete (and win) in highly competitive verticals such as insurance, finance, legal, healthcare, logistics, manufacturing, network security, cloud computing, and investor relations.
