Social proof with specificity. Not “dentists recommend” but “9 out of 10 dentists recommend.” Richard Shotton’s research shows precise numbers feel more credible than round ones. “93% of customers” beats “90% of customers” because precision implies measurement. Round numbers feel like guesses. A supplements brand changed “Thousands of happy customers” to “2,847 five-star reviews.” Same…

Avis ran the famous “We’re Number 2, so we try harder” campaign for decades. Cialdini’s weakness-first principle. Admitting a flaw before someone discovers it builds trust and reframes the weakness as a strength. “We’re not the biggest” becomes “we’ll work harder for your business.” They leaned into the underdog position instead of pretending to compete…

Airbnb shows a “This is a rare find” badge on high-demand listings that are usually booked. Different from “Popular” or “Bestseller” – “rare” implies scarcity you’ve stumbled upon by luck. You’re not following the crowd. You’ve discovered something. Triggers both urgency and ego. The badge is earned algorithmically – properties with high booking velocity relative…

An electronics retailer added Norton, McAfee and BBB trust badges directly next to the “Buy Now” button to increase confidence. Backfired completely. Placing security badges at checkout reminds people that fraud exists. It’s like a shop putting a “We Promise Not To Steal Your Card” sign at the register. Seeds doubt instead of removing it.…

Apple’s product pages have massive hero images and relatively small “Buy” buttons tucked below. Apple doesn’t need to sell you at the button – they sell you with the imagery, the copy, the specs. By the time you reach “Buy,” you’ve already decided. A giant button would feel desperate. A small button feels confident. The…

Expedia had a “Company Name” field in their checkout. It was optional. It was costing them a fortune. Users saw “Company Name” and panicked. “Am I on the wrong form? Is this for business travel? Will my personal card work?” Confusion created hesitation. Hesitation created abandonment. They deleted the field entirely. Nothing else changed. $12…

Casper’s product page shows “100-Night Risk-Free Trial” before you ever see the price tag. Mattresses are high-anxiety purchases. What if it’s uncomfortable? What if I hate it? Showing price first triggers objection mode. Showing the guarantee first neutralises risk, so the price feels smaller by comparison. The guarantee sits in bold directly under the product…

A furniture brand tested hero images: lifestyle shots (couch in a beautiful room) vs. product-only shots (couch on white background). Lifestyle images look premium but force the brain to separate product from context. White background images feel less aspirational but communicate shape, size and colour instantly. Clarity beats aspiration. They moved lifestyle imagery to the…

“Only 2 rooms left!” “12 people looking at this right now.” “Booked 6 times in the last 24 hours.” Scarcity triggers loss aversion – the fear of missing out is psychologically stronger than the pleasure of getting a deal. Booking.com turned every listing into a countdown clock. They tested urgency messaging obsessively. Red text. Pulsing…

Instead of “Fast shipping” or “Ships in 2-3 days,” a home goods brand switched to showing the exact arrival date: “Get it by Thursday, Dec 19.” Vague timeframes force mental math. “2-3 business days… is today Tuesday? When’s the weekend?” Concrete dates eliminate the calculation. Thursday is Thursday. The brain relaxes. They dynamically calculated arrival…
