The cart is where second thoughts happen
Cart abandonment is partly logistics (shipping, cost, "just browsing") and partly a final flicker of doubt. Social proof cannot fix the shipping cost, but it can address the flicker: a quiet reminder that other people made this exact choice and were glad.
What helps at the cart
- A small rating or review count on the items in the cart, quiet reassurance, not a banner.
- A short, relevant review line for the product being bought.
- Light trust signals: genuine, factual, not a wall of badges.

PDP before and after UGC: what actually changes on the page
Strip a product page back to brand-only content, then layer verified customer photos, video and reviews into the middle scroll, and watch what moves. A scroll-by-scroll look at the before and after, the numbers the public studies actually support, and where "just add UGC" gets oversold.
