Type “write me homepage copy for a B2B SaaS company” into any chatbot and read what comes back. Trusted by industry leaders. Enterprise-grade security. Results you can measure. It is competent, on-brand, and interchangeable with your three closest competitors, who ran the same prompt.
That is the problem in one screen. The claim used to be the work. Now the claim is free.
For most of advertising’s history, saying a thing cost something. You paid a copywriter, bought the media, put your name behind it in public. That cost was doing quiet work you never saw. It made the claim a signal.
In 1975 the biologist Amotz Zahavi explained why the peacock grows a tail that should get it killed. His handicap principle: a signal is only believed when it is expensive to fake. The tail is honest precisely because a sick bird could not afford to grow one. Cheap signals carry no information, because anyone can send them.
Marketing ran on the same logic without knowing it. A confident claim, well made, cost enough to fake that it meant something. Generative AI took that cost to zero. A plausible version of any promise is now a free, instant commodity. The signal still fires. It just no longer carries anything.
Buyers worked this out before marketers did.
The 2025 Edelman Trust Barometer found that 70% of people believe government leaders, business leaders and journalists deliberately mislead them. Another 64% say they struggle to tell credible information from disinformation.
Read that as a buyer’s operating system, not a headline about politics. Your prospect now assumes, by default, that the confident thing on your website was written to manipulate them, and cannot easily tell whether it is true. They are not cynical. They are calibrated. In a market where claims are free, discounting all claims is the rational move.
Notice what this does to the classic positioning statement. “We are the leading X for Y” is a claim. It was always a claim. It used to survive on the borrowed credibility of the expensive channel it appeared in. Strip that away and it is a peacock painting on a feather.
They reach for the things you cannot cheaply fake.
Nielsen has found for over a decade that 92% of people trust recommendations from friends and family above every form of advertising, and 70% trust the written opinions of strangers online. That is not sentiment. It is a rational preference for signals with a cost of forgery attached. Your neighbour has no incentive to lie to you about a dishwasher.
In B2B this is now the whole journey. Gartner puts the share of a buyer’s time spent with any vendor’s sales reps at around 17%, and its 2026 survey found 67% of buyers prefer to buy with no rep involved at all. The decision gets made in the 80% you are not in the room for: peer reviews, communities, private Slack groups, the AI summary. G2’s 2025 buyer study found that nearly half of B2B buyers now start their research with an AI chatbot, and eight in ten say AI search has changed how they research.
Sit with the mechanics of that last one. The buyer asks a machine which tool to pick. The machine answers by synthesising evidence it can find and verify: third-party reviews, documentation, named customers, independent benchmarks. It is structurally immune to your adjectives. It rewards your receipts.
Your best copywriter and your competitor’s best copywriter now produce the same sentence, for free, in seconds. The only thing left that separates you is what you can prove and they cannot.
“Show, don’t tell” has been a writing tip for a century. It is being promoted to strategy.
The question stops being “what do we want to claim” and becomes “what can we demonstrate that a rival cannot.” Those are different questions with different answers, and the second one reaches back into the product.
Proof has grades. Weakest is the claim dressed as evidence: “trusted by thousands.” Better is the specific, checkable fact: the named logo, the real number with its methodology attached, the case study a buyer can ring to verify. Stronger still is proof you do not control: the independent review, the analyst’s teardown, the audit, the public benchmark, the customer who posts about you unprompted. Best of all is proof the buyer generates themselves, by using the thing. This is why the free trial, the open dashboard, the public changelog and the un-gated tool beat the brochure. They hand over the forgery-proof signal directly.
Stripe published its documentation as a product and let developers judge for themselves. That is a proof strategy. So is a security page carrying real audit reports rather than a padlock icon and the word “enterprise.”
Now the honest part.
Proof is expensive, which is the entire point and also the entire problem. A claim ships this afternoon. A body of evidence (real customers who will speak, numbers that survive scrutiny, a reputation others vouch for) takes years and cannot be bought in a quarter. That is exactly why it works as a signal, and exactly why most companies will keep reaching for the free claim instead.
Not every category rewards the effort equally. Nobody reads a peer-reviewed study before buying a bottle of squash. Low-risk, low-consideration, emotionally-driven purchases run on distinctiveness and feeling, and always will. Proof earns its keep where the buyer carries real risk: high price, hard to reverse, reputation on the line, a committee to answer to. Most B2B. Most health, most finance, most anything sold to a cautious professional.
There is also a failure mode worse than a weak claim: fake proof. Invented case studies, bought reviews, astroturfed testimonials, a benchmark quietly rigged in your favour. Fabricated evidence is a cheap signal wearing an expensive costume, and when it gets caught, and it gets caught, it destroys the one asset the whole strategy depends on. The same tools that made your claims free made fake proof cheap too. Deloitte projects generative-AI-enabled fraud losses in the US reaching $40bn by 2027, up from $12.3bn in 2023. The market is growing antibodies to synthetic honesty. Do not be the infection.
The work, then, is not louder claims or cleverer claims. Everyone has those now, for nothing. The work is assembling the evidence a competitor would have to genuinely earn to match, then getting out of the buyer’s way while they check it.
Positioning used to be the argument you made. Now it is the evidence you hand over while the buyer makes the argument for you.
The best work starts with a conversation, and a decision worth making.
