People buy what other people buy. In a 14,000-person experiment published in Science, researchers ran an artificial music market where half the participants could see what others were downloading and half couldn’t. The exact same songs that flopped in one group became hits in the other. Popularity didn’t track quality. It tracked who could see the crowd (Salganik, Dodds & Watts, 2006). Northwestern’s Spiegel Research Center later found the same pattern in e-commerce: products with reviews can convert up to 270% better than products with none (2017). When people don’t know what to do, they copy the crowd.
A first-time visitor to your store has no signal. They don’t know you. They don’t see anyone else there. So they leave.
Boost fixes that. It turns the activity already happening on your WooCommerce store into small popups the next visitor sees: someone bought, someone added to cart, a product is running low. Real, current, hard to ignore.
Real data
Boost doesn’t invent activity. It narrates what’s already happening:
- A real purchase. When an order goes through, a visitor on a product page or the homepage sees a popup: “Anna L. from Lyon just bought Leather Wallet.” It fades away after a few seconds.
- A specific-product purchase. Same mechanism, but scoped to products or categories you pick. Useful when you want a hero product to look loved without flooding every page with every order.
- An add-to-cart. A softer signal than a purchase, but it works early in the funnel. Someone cared enough to put it in their cart, and you say so.
- Low stock. Read straight from WooCommerce stock counts. When a product drops below your threshold, the visitor on that page sees “Only 3 left in stock!” Scarcity that’s actually true.
The cumulative feeling on a quiet store matches walking past a busy café: the question shifts from “is this place even open” to “this place clearly works”.
How it shows proof without exposing customers
This is the part most social proof plugins get wrong. Showing “Anna Lefebvre, 14 rue Bonaparte, Lyon, just bought your wallet” would be a privacy disaster.
Boost was built with that in mind. It only ever shows:
- First name and a last initial. The code pulls the billing first name and the first letter of the surname, then adds a dot. “Anna L.”, never “Anna Lefebvre”.
- Town and state. The shipping town and state, falling back to billing if shipping is empty. No street, no zip code, no country shown by default.
- Product name and a link back to the product page.
Setup
1. Create a Purchase boost
Boost → Add new → WooCommerce → Transaction.
Name it, pick where it shows (homepage plus all product pages is the standard), choose a position for desktop and mobile, pick one of the six templates, save. The next paid order will fire a popup to the next visitor.
2. Add a Low-Stock boost on hot products
Boost → Add new → WooCommerce → Stock messages.
Set a threshold (default 10) and limit the boost to products where scarcity is real. Skip it if your store doesn’t track stock, or if a “Only 3 left” line on a product with 500 in the warehouse would break the moment a customer notices.
3. Decide where popups don’t belong
Use the Exclude rules on the same screen to keep popups off the cart, the checkout, and any landing page with its own message. Exclude wins over include, so the rules stay clean.
