Trust signals and badges: the conversion multiplier for unknown products
Products with five or more reviews are 270% more likely to be purchased, and trust badges near a CTA have lifted conversion 42% for first-time visitors. For an unknown product, borrowed credibility is the cheapest growth lever there is.

This study is about the cheapest conversion lever a founder has: proof that other people already trust you. Products with five or more reviews are 270% more likely to be purchased than products with none, and adding security or trust badges near a call to action has lifted conversions by up to 42% for first-time visitors in A/B tests.[1][2] New products suffer a trust deficit by default. Below we show how large the effect of social proof is, why it matters most for unknown products, and how a launch badge turns credibility into both conversions and a growth loop.

Strangers do not convert; trusted names do
When someone lands on an unfamiliar product, the first silent question is “can I trust this?” Social proof answers it before the visitor has to decide alone. The measured effect is not marginal: five or more reviews lift purchase likelihood by 270%,[1]and a lack of trust is a direct, quantified cause of abandonment, with 18% of shoppers walking away from checkout precisely because they do not trust the site.[3]
Why proof matters most for new products
Established brands carry trust with them. A brand-new SaaS carries none, which is exactly when borrowed credibility is worth the most. A recognizable “Featured on” badge, a public rank, and visible upvotes let a new product borrow the trust of a platform its visitors already know. That is why the same badge produces a larger lift for an unknown product than for a household name.
The badge is also a growth loop
A launch badge does double duty. On your site it is social proof that lifts conversion. Pointed back at the platform, it is a backlink and a referral path that brings new founders in, who launch, earn badges, and embed them in turn. The credibility signal and the distribution loop are the same object.
- On your page: a verifiable badge raises conversion by borrowing platform trust.
- For the platform: each embedded badge is a backlink and a referral source.
- For the ecosystem: more launches means more badges means more trust and reach for everyone.
How Flamas uses this
Winning on Flamas earns badges you can embed on your own site: real, verifiable social proof that links back to a genuine result page. That badge lifts your conversion today and feeds the platform’s growth loop, which is covered in depth in the companion study on the discoverability flywheel. See how it works or start your launch.
Frequently asked questions
Do trust badges and social proof actually increase conversions?
Yes, and measurably. Products with five or more reviews are 270% more likely to be purchased, trust badges near the CTA have lifted conversion up to 42% for first-time visitors, and 18% of shoppers abandon checkout because they do not trust the site.
Why does social proof matter more for new products?
Established brands already carry trust; a brand-new product carries none. That is exactly when borrowing credibility, through a recognizable badge, a public rank, or visible upvotes, produces the largest lift.
How is a launch badge more than just decoration?
It does double duty: on your site it is verifiable social proof that raises conversion, and pointed back at the platform it is a backlink and referral path. The credibility signal and the growth loop are the same object.
