It’s easy to get the wrong idea about B2B content right now. AI lets businesses churn out social posts in seconds and full articles in under a minute. Businesses feel they need more, more, more content to feed what they believe to be the short attention spans of audiences worn down by constant notifications and media overload. You may think that sounds ironic.
And now, we have AI search. Depriving endless websites of precious clicks, every man and his dog wants to appear in ChatGPT’s answers when their prospective customer asks a relevant question. But nobody knows exactly how to make that happen.
So, where does long-form B2B content stand among all this? The lengthy articles, customer stories, whitepapers, and reports we’re told nobody has time to read (or create, for that matter). Have they died a death in this frantic, AI-fuelled world?
Not at all. They’re alive and more important than ever, thank you. Let’s look at why that is.
Long-form B2B content remains important because of AI
Consider what a piece of long-form content might look like. Take a report, for example. It may be shaped around internal data or research the business has carried out. That alone is interesting to the market. The report may also contain commentary from subject matter experts – both from within the business and industry specialists. These clever people may explain logic behind the data, highlight trends worth noting, or offer valuable guidance to readers.
This format sounds like the makings of a decent read. If I were seeking to get my head around that topic, I’d want to read carefully, even if it took 20 minutes or so.
A couple of report examples from my own experience:
1. A 12,000-word belter that included in-depth commentary from 11 senior subject matter experts across the sector and data from several reputable sources
2. A monthly benchmark report combining internal and external data, real-time trends, and guidance from internal and external experts
Unique data, distinctive commentary, expert-driven advice. Exactly the kind of things that demonstrate authority and build trust. Which is why we’re seeing AI tools cite high-quality long-form and pillar content when answering questions.
I believe long-form B2B content has always earned its place in a robust content marketing strategy, and the “short attention” argument has flaws when it comes to B2B. Granted, people don’t want to read fluffed-up, lengthy drones full of low-value words, but they do want to learn and understand before making smart buying decisions.
And now, AI has spotted that value. Human insight that’s fresh, interesting, and authoritative.
But here’s the conundrum for plate-juggling marketers: AI doesn’t want long-form B2B content written by AI tools. It wants to cite pieces rich in insight, thoughtfully written by people who understand the business.
So, if you hadn’t appreciated that human-created long-form content was *still* valuable for every B2B target audience on the planet, understand that your AEO strategy will now depend on it.

Long-form content deserves your time and budget
The average B2B buyer cycle is getting longer. The 2026 Dreamdata report says it’s now 272 days, up from 211 days in 2025. It can also involve an average of 88 touchpoints and 10 stakeholders, with 81% of the buyer’s journey happening before they enter the sales pipeline.
In short, B2B buyers are spending an average of seven months researching problems and options before they even speak to you. Given the resulting purchase could be worth £10,000, £50,000, or even £200,000, it makes sense to nurture that journey.
I always say the purpose of content is to change how people think. While quick content snippets and posts play their part, long-form pieces do much of the heavy lifting here. Plus, they offer potential for months of repurposing. And given that long-form and pillar content now has the attention of AI, its ROI has only been bolstered.
Authoritative expertise carries a premium though, whether your buyer finds it directly or AI surfaces it for them. While it’s worth its weight to inform, educate, and influence, I appreciate these beefy pieces take time and resources to create (and creating them properly is worth that investment). That’s why every long-form B2B piece needs a robust distribution and repurposing plan from the outset.
You know the kind of thing. One whitepaper can typically become a series of shorter articles, an email newsletter feature, a handful of social posts, a webinar or podcast discussion, a one-pager in the sales deck, and a collection of pull-out statements to use across your materials.
My advice? Go deep on your topic then repurpose like hell. That’s how to achieve the greatest return on your investment. And that’s how you keep showing up in that 272-day journey.
If it were me, I’d select a small number of topics and do them absolute justice, because a solid whitepaper or report can help fuel your content plan for several months.
How B2B buyers evaluate vendors today
Survey data suggests 67% of a buyer’s journey now happens without direct engagement. Most buyers prefer to educate themselves without involving salespeople. With the advent of large language models such as ChatGPT and Claude, this has become much easier to do.
But it’s created what some are calling The Great Decoupling. Traditional inbound content marketing models where prospective customers exchange contact details for education are being replaced by free-to-all AI insight. Plus, buyers no longer need to visit a vendor’s website to access information because AI serves it up in bucketloads.
While it’s become harder to track almost 70% of your buyer’s journey, it’s clear that fresh, human-derived, long-form content is more likely to be cited by AI and help you influence your prospective buyer’s thinking. This is reinforced by 58% of marketers noting that AI referral traffic has much higher intent than traditional search. A silver lining perhaps?
Where long-form B2B content can go wrong
Long-form content has huge value, but finding fresh, in-depth topics your audience will actually care about is hard. In Hubspot’s 2026 State of Marketing Report, 35% of marketers say their top challenge is creating content that receives high levels of engagement. The second highest challenge, they say, is finding ideas for new content (28%).
And while AI tools may make content easier than ever to create, it’s harder than ever to create high-quality long-form content that connects and influences. 55% of marketers struggle to differentiate their content in an AI-saturated market. Plus, AI-generated content generally lacks emotive and original thinking, along with the first-hand experience that buyers *and* large language models want to read.
High-quality long-form content that shifts thinking remains a job for experienced B2B writers, smart marketers, and proactive subject matter experts.
Repurposing has become another headache for content marketers. Many don’t have the time or budget to carry it out effectively, missing opportunities for further reach and additional ROI from the same content pieces. The trick is to build it into a content campaign from the outset instead of thinking about it as an afterthought. But that’s a discussion for another day.
Interestingly, I’ve heard many businesses that chose to swap content writers for AI outright have seen conversion rates drop and cost-per-acquisition rise. The resolution, I’m told, has been to involve experienced writers… again.
How to create long-form B2B content in the age of AI
When you boil it down, the principles haven’t changed. Long-form B2B content exists to educate and influence prospective customers throughout their lengthy buying journey. When you create it with authority, each piece builds trust and moves the prospect closer to a conversation with you. The fact they might now be 70% of the way there before they pick up the phone or send you an email doesn’t matter. You could argue they’re more motivated when they eventually get in touch.
So, develop and document your content strategy as normal and know what pillar topics you want to focus on. My advice is to be selective and cover each one effectively.
Interrogate your topics (ideally with your team) and establish how you can go deep. Quick and dirty blogs simply won’t cut it now. This is where long-form content comes to life and works hard for you. Plan a central piece, or perhaps a theme that runs through a series. Go deep. Give it your best.
Involve subject matter experts whenever you can. Make time for the conversations and ask the searching questions. If you go cold at the thought of doing this, hand it over to your outsourced writer. They’re probably having chats like this most days. In fact, I’d involve them in your process as early as you can because it always pays off.
Use AI tools where they help most: sparking ideas for discussion, searching for reputable sources (always check them yourself), even suggesting a potential structure. But make sure your people control the interviewing, planning, and drafting. And create something valuable that sounds like your business. Yes, you may involve AI as an editing partner once you’ve drafted the piece, but make sure it understands your voice and objectives. Then use your own judgement on every suggestion. Human-led, remember?
What to look for in a freelance long-form content writer
Given many businesses turn to freelance writers when creating long-form B2B content, it’s important to know what skills you need, because that’s far more than a pen for hire.
They have perspective on your industry (or the ability to understand at pace)
Understanding industry terms and how things work always helps. But many experienced writers know how to get to that point quickly. If they tick every other box, ask them how they do it.
They have experience writing the content formats you’re creating
To me, this is more important. Every long-form content format has a typical structure that works and pitfalls to avoid. Such familiarity also helps readers find what they need more easily.
They’re comfortable interviewing senior subject matter experts
A nervous or shallow interviewer won’t do your SME conversations justice. Ask your writer where they stand on this because it’s a skill that many take years to learn.
They know how to adopt your brand voice
You want your content to sound like you, not them. They should be asking for brand voice guidelines or existing content you feel comfortable standing by.
They know how to use AI when it matters
Most writers use AI to some extent. The art is knowing where it may help (research, for example) and where it won’t. You’re looking for human-derived content, after all.
They have a reputation for high-quality delivery
Knowing they’ve done this before reduces your risk. Experienced writers will have examples, recommendations, and happy clients you can get in touch with.
They can help you with repurposing
Support doesn’t need to stop once you’ve finished the long-form piece. Let your writer take the strain on repurposing too, so you don’t have to.
Great long-form B2B content remains pivotal
Great long-form B2B content still earns its keep. High-quality pieces designed to influence how your prospective customers think have been central to B2B content marketing for years. They’ve survived the alleged attention deficit, and they’re now thriving as AI changes how buyers find and trust information.
Given web traffic is plummeting, long-form content provides you with a fresh opportunity as large language models such as ChatGPT, Claude, Gemini, and Perplexity cite authoritative and trustworthy pieces in their answers.
So yes, human-derived long-form B2B content is absolutely more important than ever today. Businesses that prioritise creating their own fabulous pieces will stand apart from competitors still trying to work out how to make AI write better. They’ll also earn trust from prospective customers who’ll buy from them when they’re ready.
