Nudgify is an affordable entry point for social proof. Here is why growing merchants look for more.
Nudgify focuses on recent purchase notifications and visitor counts. ProofNudge provides 60+ variables including cart activity, sales velocity, compare-at pricing, collection-level stats, and product rankings — giving you far more ways to create compelling messages.
Show a low stock alert only when inventory actually drops below a threshold. Display a trending product badge only when a product hits a view count milestone. Conditional logic ensures your messages are always contextually relevant, never generic.
ProofNudge can show messages like "#2 most viewed in Running Shoes" or "Top seller in Summer Collection." These ranking badges and collection-scoped variables give shoppers social proof that is specific and meaningful, not just a generic visitor count.
Nudgify is limited to corner notification popups. ProofNudge lets you embed messages as inline theme blocks, overlay them on product images, or target any element with a CSS selector. Place the right message exactly where it has the most impact.
Nudgify keeps things simple with a handful of notification types. ProofNudge gives you a full template engine with 60+ variables, so you can craft messages that reflect your store's actual activity in fine detail. More variables means more precise, more persuasive messaging.
With conditional logic, a single ProofNudge campaign can show different messages based on the product's current state. High stock? Show popularity. Low stock? Show urgency. Discounted? Highlight savings. The right message appears automatically without manual intervention.
ProofNudge reads directly from Shopify's Liquid storefront context — stock levels, variant availability, pricing, compare-at pricing, tags, and collections. No extra API calls, no sync delays. The data your messages display is always current.
