Scarcity Badge ("Selling Fast")
Type: Component Test · Where It Runs: Product Page · Setup Time: ~5 min
Test whether adding a "Selling Fast" urgency badge to your product page increases add-to-cart rate by creating a sense of scarcity.
Video Walkthrough
Why This Works
Shoppers hesitate. They open a product page, look around, think about it, and leave with the intention of coming back later. Most of them never do. A scarcity signal like a "Selling Fast" badge with a live viewer count creates a reason to act now instead of later.
It works because it introduces two psychological triggers at once: social proof (other people are looking at this right now) and urgency (if I wait, it might be gone). Together, these reduce the "I'll think about it" behavior that kills conversion rates.
The badge sits right before the buy button, which is exactly where hesitation happens. It's a small, low-risk addition that can have an outsized impact on add-to-cart rate.
Best For
Products with broad appeal and high traffic
Limited edition or seasonal products
Impulse-friendly price points
Stores running sales, drops, or promotions
Any store that wants to reduce purchase hesitation on the PDP
How to Set It Up
In your Elevate dashboard, click Page Experiment
Give your experiment a name (e.g. "Adding Urgency Badge on PDP") and add a description of your hypothesis
Set your primary metric to Add-to-Cart Rate. All metrics are tracked and visible on your test dashboard, but this one determines when the test hits statistical significance
Select Product Page as the target. Run it on all products, or click Show specific products to narrow it down
For the variation, click Add Custom Component. Select Selling Fast Badge from the list
Choose the placement. Elevate recommends before the buy button, which is a strong default. Hit Next
Select your primary template to duplicate, then click Duplicate. Elevate will create a copy prefixed with "eab"
Click Edit in Shopify to open the duplicated template in the theme editor
You'll see the selling fast badge already added. Click on it to customize the text, colors, font size, and viewer count range. Elevate pulls your store's color system automatically, but you can adjust anything to match your design
Adjust the viewer count to be realistic for your store. The default range might be too high. Dial it down to something believable for your traffic level (e.g. 10-15 viewers instead of 50+)
Hit Save in the theme editor and go back to Elevate
Preview both the variation and control on desktop and mobile
Leave traffic split at 50/50. No need to isolate traffic or set audience targeting
Click Create Experiment to put it in preview state, do a final QA check, then Launch
Alternative setup: You can also add the selling fast badge directly to your theme without going through the page experiment flow. In the Shopify theme editor, click the + button, go to Apps, and you'll see Elevate's custom components including the selling fast badge. This is useful if you want to add it permanently without testing.
What to Look For
Primary metric: Add-to-cart rate. This badge targets the moment right before the add-to-cart action, so that's the clearest signal of whether it's working.
Also watch: Conversion rate and revenue per visitor. You want to make sure the urgency is driving real purchases, not just more adds-to-cart that don't convert. If add-to-cart goes up but conversion stays flat, the urgency might be creating impulse adds that don't follow through to checkout.
Timeline: 1-2 weeks for most stores. This is a straightforward component test that tends to reach significance quickly.
