“LeanConvert was an ideal partner for our first step into the world of optimisation.”


Quiz is a leading UK retailer offering fashion’s latest trends in occasion-wear at affordable prices, keeping their customers and their preferences in mind at all times. Whilst it is a market leader at product curation, picking out the best pieces and trends for their customers’ ever-evolving tastes, Quiz had never before forayed into the world of experimentation and optimisation but understood it could unlock value for them.

Attributed revenue with social proofing

We were excited to work with Quiz because of their data-driven approach to decision-making. The combination of the artistic side of trend prediction and the laser focus needed for buying made it a really fascinating challenge for us to support. Our goal was to support the quality of their in-store experience online.

What happened next?

Maximising opportunities

In order to maximise the opportunities around Black Friday and the Holiday Season, by far two of Quiz’s most crucial shopping periods, LeanConvert built a 1:1 sales feature that allowed Quiz’s merchandising team to sell to specific groups at specific times, enabling them to change products and deals on the fly based on data-driven performance, rather than guesswork.

Weeding out inefficiencies

Quiz had two recommendation engines that both delivered uplift. LeanConvert tested the two against one another in order to see which should be cut in order to reduce costs and drive the most positive customer experience. After identifying the more effective recommendation technology, we set about optimising the placement of this technology on Quiz’s site and fine-tuned the recommendations based on whether a visitor was new or returning. New visitors were presented with the site’s most popular items at that particular moment, whereas returning visitors were given recommendations based on what was relevant to them based on their interests and tastes.

Improving CX with social proofing

In order to inform shoppers that a product they might like could sell out, LeanConvert tested ”Quick! Only x left!“ messaging on shoppers’ baskets for items whose stocks were 20 or less. As fashion is an inherently social product and industry, this type of social proof messaging was crucial in improving Quiz’s CX, ultimately leading to a massive increase in revenue. Plus, LeanConvert’s tech-agnostic approach to social proof allowed Quiz to drop third party tags from their site, immediately increasing site speed and reducing tech clashes.

Better together

LeanConvert was an ideal partner for our first step into the world of optimisation. They helped us understand which technology we needed, what we needed to do to maximise key shopping periods, how to deliver social proof that put us in-line with the rest of the market, and more. Their approach helped us optimise key areas of the website which resulted in an increase in key stats. LeanConvert also helped us validate certain features and technology, cut costs by dropping inefficient vendors, and improve the overall user experience.
