Ever bought a car and suddenly seen the same model everywhere? Those cars were always there. The only thing that changed was your brain: it updated its list of what counts as relevant.
Pop psychology credits a nerve bundle in the brain stem, the reticular activating system, with this job. In reality several brain networks share the work of deciding what gets attention, but the idea of a bouncer at the door is a useful one. And the bouncer has a simple door policy.
What the bouncer lets through
It admits what looks highly relevant (tied to your goals, your name, your safety) or genuinely unusual (anything that breaks an expected pattern). It turns away the predictable. If your marketing looks, sounds and feels like every other ad in your category, it doesn't get in.
You don't need to be the loudest thing in the room.
You need to be the one thing the brain wasn't expecting.
Trigger 1 · The first-seconds window
People decide whether to keep reading or scroll on in a second or two. You'll see precise figures quoted, like "2.8 seconds". There's no magic number, but the window is tiny: not enough time for a story or an argument, barely enough to register what's in front of them.
Use it: frontload your best material. Put your biggest promise, most surprising number or most arresting image first. Don't build up to it.
- Email: the payoff goes in the first line, not paragraph three.
- Video: open on the result or the most dramatic moment, then back up to explain.
- Landing page: the headline carries the single biggest promise. Everything else supports it.
Trigger 2 · Pattern interruption
As people scroll, the brain predicts what comes next and processes it on autopilot. A pattern interrupt breaks the prediction, so conscious attention has to switch on. The most reliable way to build one is contrast:
- Visual contrast: if every competitor uses glossy studio photos, try a raw smartphone clip.
- Tonal contrast: if your industry drowns in jargon, try plain honesty. A law firm that opens with "Most lawyers won't tell you this, so we will" stands out because the category never sounds like that.
- Contextual contrast: put something familiar somewhere unexpected, like a luxury watch on a sawdust-covered workbench.
The bridge rule: an interrupt only buys attention. You must bridge it to real value straight away. Squatty Potty's famous unicorn advert is the classic example: a bizarre hook stopped the scroll, then bridged straight into a genuine explanation of the product. If you can't write the one-sentence bridge, the hook isn't ready.
Trigger 3 · The Von Restorff effect
The brain remembers what stands out. When everything on a page looks similar, it all becomes background. When one element is dramatically different, it's noticed.
Use it: make your call to action the most visually distinct thing on the page. If your brand colours are blue and white, try a bright orange or green button with plenty of space around it. Subtle doesn't work here.
Trigger 4 · Authority markers
To save effort, the brain leans on shortcuts, and deferring to credible experts is one of the strongest. But credentials only help if they're seen early. Buried at the bottom of the page or behind an "About" link, they do nothing.
Use it: put genuine credentials in the first screen: real press logos, years of experience in the subheading, qualifications next to your name. Only use what's true.
Trigger 5 · Specific social proof
Round, fuzzy claims like "thousands of happy customers" trip the brain's scepticism, because it has learned that round numbers are often invented. Exact figures read as real, because people assume you wouldn't make up something so precise.
Use it: replace every vague claim with a specific, true one. "Highly rated" becomes "4.8 stars from 1,293 reviews". And if you don't have impressive numbers yet, don't invent them. Lean on the other triggers until you do.
