When B2B teams build complex products, they almost always make the same mistake on their website: they assume their buyers will do the work. They list every feature, mix value propositions with technical specs, and bury the thing Sarah actually needs to know underneath the things the internal team finds impressive. The result is a page that communicates nothing clearly to anyone.
This is the curse of knowledge— a cognitive bias coined by economists Camerer, Loewenstein, and Weber. Once you know something deeply, you can't unknow it. And it makes it very hard to write for someone who's encountering your product for the first time, under time pressure, with fifteen other tabs open.
Sarah is that person. It's 2:30 pm on a Thursday. She has back-to-back meetings, fifty unread emails, and she's trying to figure out what to cook for dinner while simultaneously worrying about her team's capacity. Her cognitive load is maxed out. She's been tasked with buying new project management software — a high-stakes purchase that could either transform her company's efficiency or become a costly mistake attached to her reputation. She is looking for a lifeline. Instead, you hand her a manual.
When you build a complex product, you know exactly how powerful it is. You know it handles procurement, enterprise security, and intricate workflows. Because you know this, you assume Sarah needs to know it too, right now, on the homepage.
So you write copy that accommodates every stage of the funnel at once. You list every feature. You mix high-level value propositions with technical specs about API integrations.
You assume that if you put all the information out there, Sarah will sift through it, find what's relevant to her, and connect the dots. She won't. She doesn't have the time.
Buyers are increasingly avoiding sales calls and trying to self-serve. According to the 6sense 2025 B2B Buyer Experience Report, 83% of buyers mostly or fully define their purchase requirements before they ever speak to sales — and 95% of the time, the winning vendor is already on their Day One shortlist. Your website has to do the heavy lifting before a conversation starts. Heavy lifting doesn't mean heavy reading. If Sarah has to work to understand what you do, she'll tab-switch to a competitor who makes it easy.
The best brands don't simplify their product; they simplify the path to the product.
Look at the project management space. It's arguably one of the most crowded, feature-heavy markets in SaaS. Yet players like Wrike, Asana, and ClickUp manage to sell complex tools without overwhelming the user.
They don't treat their website like a warehouse; they treat it like a concierge. They use use cases and personas to split the traffic immediately. They know that a Creative Director needs to see visual proofing tools, while an Operations Lead cares about resource allocation. They don't force the Creative Director to wade through IT security compliance just to see if the calendar view works.
"But look at HubSpot," teams often tell me. "Their messaging is broad. They talk about 'growing better' and 'AI platforms.' Why can't we do that?"
It's dangerous to look at a market leader like HubSpot and try to mimic their 2026 strategy when you're still in your growth phase.
If you look at HubSpot's homepage today, it's arguably a mess of contradictions. The hero messaging is vague and doesn't align with the rest of the page. They're trying to speak to everyone, from a two-person startup to a global enterprise, all at once. There's "AI" shoved into every paragraph, and the distinction between the "Platform" and the "Hubs" is blurry.
But here's the difference: HubSpot can afford to be vague. They've spent fifteen years and millions of dollars building a brand synonymous with CRM software. When Sarah lands on their site, she already knows what they do. They've earned the right to be cerebral, adventurous, or even slightly confusing with their copy.
You haven't. For most teams, "bland and generic" isn't a branding choice; it's a death sentence. You don't have the brand equity to carry a vague message. You need to be specific, clear, and immediately useful.
The biggest pushback I hear from teams is: "But our enterprise clients need to know about our ISO certification!"
Yes, they do. But do they need to know it in the hero section of the homepage?
This is where the internal battle begins. Sales wants one thing, Product wants another, and Marketing is stuck in the middle trying to please everyone. The result is usually a Frankenstein website that says everything and communicates nothing.
You can't guess your way out of this loop. You have to research your way out.
Many teams try to skip this step. They jump straight to A/B testing headlines or button colours. The hard truth is that A/B testing is useless if your fundamental assumptions are wrong. If you misunderstand who your customer is or what they actually care about, you're optimising for the best version of a bad message. You end up with the winner of the wrong information.
Gartner's 2025 research found that 61% of B2B buyers already prefer a rep-free buying experience, and 73% actively avoid suppliers who send irrelevant outreach. The message has to work before Sarah is in a conversation with anyone. That only happens when you understand what she actually cares about, in her language, not yours.
To fix the curse of knowledge, you need to leave the building and gather evidence.
You need to talk to the different humans involved in the deal: the buyer who triggered the search, the user who actually logs in every day, and the champion who had to sell the decision internally. Often, the thing you think is your headline feature is a minor detail to them, while the "boring" integration you buried in the footer is the reason they signed.
Your internal data tells a version of the same story. Sales can tell you the difference between a small deal and an enterprise deal; what the first three questions a big prospect asks compared to a small one. Your closed-lost records show whether they said no because of price or because of confusion. Churn reasons reveal whether people left because the product didn't do what they thought it would — which is nearly always a messaging gap, not a product gap.
When you have this research, the internal debates stop. You don't have to argue with the Head of Product about whether the "audit trail" feature needs to be on the homepage. You can simply look at the data and say: out of 20 recent enterprise buyers, only one asked about audit trails in the first meeting. It goes on the secondary page. Research gives you the confidence to curate. It lets you build a site that respects Sarah's time, speaks to her actual problems, and helps her make that purchase decision without the headache.
If the human argument doesn't convince you to simplify, the technical one will. Tools like ChatGPT and Perplexity are becoming the new gatekeepers. These tools scan your site to understand what you do and who you're for.
If your messaging is a soup of jargon, conflicting value propositions, and tech-speak, the AI can't categorise you. If it can't understand you, it won't recommend you.
Your product might be complex, but your story shouldn't be.
If you're planning a product launch or a website refresh, don't wait until the design phase to think about this. The structure and the story come first.

What is the curse of knowledge in B2B marketing? The curse of knowledge is a cognitive bias first described by economists Camerer, Loewenstein, and Weber in 1989. In B2B marketing, it occurs when teams who know their product deeply write copy that assumes buyers share that knowledge. The result is messaging that feels clear internally but lands as jargon or clutter to someone encountering the product for the first time.
Why do B2B websites often communicate poorly? B2B websites often fail because they're written from the inside out: they reflect what the internal team values rather than what buyers need to know. When multiple stakeholders contribute competing priorities, the result is a page that tries to serve everyone and ends up serving no one clearly.
How does self-serve buyer behaviour affect B2B website copy? According to the 6sense 2025 B2B Buyer Experience Report, 83% of buyers mostly or fully define their purchase requirements before speaking to sales, and 95% of the time the winning vendor is already on their Day One shortlist. This means your website is doing the convincing work before any conversation happens. If the copy is unclear or overloaded, the buyer moves on without you knowing.
What's wrong with copying a market leader's messaging strategy? Market leaders like HubSpot can afford broad, abstract messaging because they've spent years building brand recognition. For a company still establishing itself, vague messaging is a competitive liability. Buyers need to understand immediately what you do, who it's for, and why it matters to them. Brand equity is what earns the right to be aspirational.
How does customer research fix bad B2B website copy? Customer research reveals the gap between what teams think matters to buyers and what buyers actually care about. Talking to buyers, users, and champions across the deal cycle surfaces the language, priorities, and questions that should be driving the copy. It also stops internal debates about what to include by grounding decisions in evidence rather than opinion.
What internal data helps improve B2B messaging? Sales conversations, closed-lost records, and churn reasons are among the most useful sources. They reveal whether buyers are confused about what the product does, what features they actually ask about in early conversations, and whether people leave because the product didn't meet expectations set by the messaging. All of this is available without running a formal research programme.
Does AI search reward clearer B2B website copy? Yes. AI tools like ChatGPT and Perplexity scan websites to understand what a company does and who it serves. If your messaging is filled with jargon, technical overlap, and competing value propositions, these tools struggle to categorise you and are less likely to surface you in relevant queries. Clear, specific, audience-led copy benefits both human and AI readers.
