Genie Fashion: Shopify Speed and Conversion Optimisation
Speed and checkout work on a Shopify fashion store so product pages load quickly on a phone and fewer shoppers give up before paying.
The Challenge
Slow mobile loading during flash sales cost Genie.pk revenue and carts on its busiest social media campaigns. Flash sales are a spike problem, not an average problem. A store can perform perfectly all month and still lose the only hours that matter. When a campaign lands, thousands of people arrive on mobile within minutes, all hitting the same product pages, all having been promised a limited window. There is no patience in that traffic. A shopper who waited three seconds on a normal day will abandon in one during a sale, because the scarcity that drives the urgency also removes any reason to persist. Fashion compounds it. Product pages are image-heavy by nature, customers browse many items before choosing, and most of that browsing happens on phones on mobile data.
What We Built
We attacked the parts of the page that cost the most time on a phone. Edge asset caching moves static content geographically closer to the shopper, so the round trip is shorter and the origin server is not asked to serve the same assets thousands of times during a spike. This is what keeps the site standing under campaign traffic rather than degrading as load climbs. Optimised image formats address the single largest weight on a fashion product page. Modern formats cut image payload substantially at the same visual quality, which on a phone translates directly into how fast the product appears. A single-page cart drawer removes a full page load at the exact moment the customer has decided to buy. Every navigation between decision and payment is an opportunity to lose them, and during a flash sale that opportunity is taken. Direct COD and Stripe payment gateways cover how customers actually pay. Cash on delivery remains essential in this market, and a checkout that does not offer it loses a large share of buyers regardless of how fast the rest of the page is.
What Changed for the Client
The store now copes with flash-sale traffic spikes, and Genie.pk recorded its highest single-day revenue to date. The useful result is that campaign spend stopped being wasted. When a store falls over during a flash sale, the advertising that drove the traffic is paid for either way. Fixing the store did not just improve conversion, it recovered the money already being spent to bring people to it.
