Proof review

It watches for real events (a transaction in your store, an opt-in from your email platform) and shows them as live notifications on your sales or landing page, so a visitor sees that someone in Wisconsin just bought the thing they're considering. People take their cues from others, and seeing that someone just went first lowers the risk of going first.

Bigger launches: multi-six and seven-figure ones, where activity is steady enough that notifications keep arriving while someone reads the page. That accumulation is what convinces, and the whole tool depends on it. Below that volume, notifications are sparse, and a page quietly announcing that almost nobody is buying is worse than one that says nothing.

It's FOMO, and whether it's manufactured is down to you. Proof reports genuine events (real purchases, real opt-ins), which shows visitors something true they'd otherwise never know. Sites inventing activity have poisoned the category, so audiences now read the popup as a tell. Fabricate it and you aren't building trust; you're spending it.

When the purchase is considered rather than impulsive. Proof suits high-volume, lower-consideration buying where activity is constant and visible. For a thoughtful expert's audience or a B2B sale with a long decision, a real testimonial shows that other people trusted you, without the whiff of urgency tactics. Be honest about which kind of sale you're running.
