@CROguy_Why guarantees matter on the homepage
Many homepage visitors are new to the brand and have not looked at a product yet.
A guarantee near the hero answers "what if this doesn't work for me?" before they click through.
On the homepage it competes with the headline, images and offer for attention, which is why it shows up inside bundled hero tests here.
Measured results
Hero banners with a guarantee (2 tests)
Dave Diederen tested a new banner layout with a problem headline, two CTAs, reviews and a guarantee.
It won +17.12% conversion rate, +22.12% revenue per visitor, +22.86% profit per visitor and +4.27% AOV, worth +$28,163 a month in profit.
In a second test, Dave Diederen ran four hero banner variations that changed social proof position, trust badges, delivery and guarantee benefits, and CTA hierarchy.
The winner added +15.52% conversion rate, +13.98% revenue per visitor and +14.29% profit per visitor.
A trust FAQ that covers returns (1 test)
A trust-focused FAQ section answering shipping, returns, payment and legitimacy questions won +$8,984/month and +1.15% revenue per visitor over 26 days and 96,093 visitors.
It is the smallest lift here, but it is also the narrowest change.
@DaveDiederen@DaveDiederen@DaveDiederenLosing or flat tests
None of the three lost. Because each test changed several things at once, the guarantee's own share of each win is unknown.
No one here has shared a homepage test that added only a guarantee.
Untested ideas
All four ideas put the guarantee next to the hero CTA:
- Dave Diederen suggests a trust-stacking test: offer only, offer plus a rating badge and guarantee, and offer plus free delivery and guarantee. That design would finally show what the guarantee adds.
- Milos suggests replacing a slogan hero with a benefit headline, science-backed ticks, a CTA with a 30-day guarantee and a 4.9/5 rating.
- Milos also suggests a rating bar, a clear headline, three benefit badges and a CTA with a happiness guarantee, showing the actual product boxes.
- A third Milos concept swaps a dark lifestyle photo for a bright product shot and adds a guarantee next to the CTA plus units-sold proof above the fold.
Placement and design patterns that won
- The guarantee sits in the hero, close to the main CTA, not in the footer.
- It appears with other proof: reviews, ratings, delivery promises or trust badges.
- A plain FAQ that answers returns questions can help even outside the hero.

Guarantees have far more evidence on product pages, where several isolated tests won.
