Specificity beats superlatives
"Industry-leading platform trusted by innovative teams" could be written about any company in any category, which is precisely why it persuades nobody. Every competitor makes the same claim, so the buyer's discount rate on adjectives is total. Specificity works because it is expensive to fabricate: "cuts month-end close from nine days to two for finance teams of 5-20" names an audience, a before, an after, and a unit. It also does something a superlative cannot — it disqualifies. A visitor with a 200-person finance team leaves, which is a win, because unqualified demos are the most expensive thing on your funnel. The test we apply to every headline: could a direct competitor put their logo on this sentence and ship it unchanged? If yes, it is not a headline, it is wallpaper.
Show the metric and show the method
A number without a method is just a louder adjective. "3x more conversions" invites the obvious question — over what baseline, across how many users, measured for how long? Publish the mechanism next to the outcome: "Conversion on the trial signup went from 4.2% to 11.6% over an eight-week A/B test, 34,000 sessions, driven by moving verification after first use." That paragraph is longer and it outperforms the punchy version, because it survives scrutiny by the sceptic in the buying committee who has been burned before. Where you cannot share a real number, say so plainly rather than rounding up — "under NDA, but the pattern is in our onboarding write-up" reads as honest. Round numbers read as invented; 41% is more credible than 40%, and it should be, because it is true.
Handle the objection above the fold
Every buyer arrives with two or three specific reasons this will not work, and they are rarely about features. It is price, migration effort, lock-in, security review, or whether you will still exist in three years. Standard practice buries those in an FAQ at the bottom, which means the sceptic bounces before reaching the answer. Put the biggest one in the first screen, phrased as they would phrase it. If cost is the objection, show the price. If migration is the fear, show the timeline and who does the work. Interview five recent lost deals and five won ones, then write down the actual sentences people used — that transcript is your page copy. Answering the hard question early reads as confidence, and confidence is the thing you cannot claim, only demonstrate.
Why testimonials underperform case studies
"Great team, highly recommend" from a named VP with a headshot is still an opinion, and buyers read pull-quotes as marketing-selected — because they are. Case studies work harder because they carry structure a testimonial cannot: the situation, the constraint, what was tried, what was measured, and what did not work. That last part is the credibility engine. A case study admitting the first approach failed and explaining the pivot is more persuasive than three glowing quotes, because nobody fabricates a setback. If you only have quotes, make them specific and operational — "they shipped a working demo every Thursday for eleven weeks" beats "a pleasure to work with" by a distance. And place proof next to the claim it supports, not in a carousel at the bottom that nobody scrolls to.
