The Full Story

Luxury fashion retailer L’Exception counts on Centreon DEM to ensure peak performance and underpin revenue growth at sales time.

A Fresh Vision of Fashion Retailing

L’Exception is a leading independent retailer of creative and luxury fashion. The company carefully curates the best products and endeavors to offer quality and creativity at affordable prices. From renowned luxury brands to up-and-coming designers, L’Exception aims to constantly surprise and delight its customers.

In the world of L’Exception, the customer experience is everything. It wants shoppers to discover and explore its designers and collections, and to engage with their rich and exciting worlds. The virtual experience must be as immersive and memorable as the physical alternative.

Web performance: The Key to Revenue Growth

Making a success of retail sales periods and promotions is essential for L’Exception’s revenue growth. It is also a condition for its sustained growth as an e-commerce player.

Prior to calling on Centreon DEM (formerly Quanta, following the acquisition of Quanta by Centreon), L’Exception was experiencing server stability issues. The site was frequently unreachable and nobody could clearly identify the causes. Handling peak traffic was a particular problem during busy sales and promotional periods. Degraded site performance and page loading speeds were hindering conversion rates – not to mention damaging its e-reputation and brand experience. Simply put, the longer it took for pages to load, the more customers were dropping out.

L’Exception needed to take action. Fast.

“Web performance is all about protecting revenue. The longer you put off optimizing your web performance, the more sales and customers you lose to a faster competitor. We needed a complete, objective and quantifiable view of our site’s performance. We wanted to prioritize our optimization efforts and to understand what was working and what was not,” says Regis Pennel, Founder at L’Exception.

Centreon DEM’s experts started by measuring the frequency of L’Exception’s service interruptions and then pinpointing their causes. Once the origins of technical issues had been identified, Centreon DEM’s web performance gurus advised L’Exception on the optimal way to resolve them. The Centreon DEM platform also identified latent issues, ensuring they were addressed before they could impact performance further down the line.

Ensuring Optimal Customer Experience and Conversion Performance at Sales Times

Centreon DEM provides L’Exception with a continuous, comprehensive view of the web performance of every page and conversion funnel. The team can review and optimize web performance page by page.

As the sales period approaches, L’Exception relies on the Centreon DEM platform to guarantee a stable digital experience during traffic peaks. Each page and conversion path is monitored closely to ensure it performs reliably during this critical time.

The company’s e-commerce platform uses several third-party technologies to enhance the user experience. Centreon DEM ensures these add-ons do not hamper speed or increase page weight.

In e-commerce, images are key to driving clicks and conversions. In luxury retail, the bar for image quality is set even higher. However, larger and higher resolution images weigh heavier on load times. With Centreon DEM, L’Exception is sure of serving the best quality images without negatively impacting page performance.

“We use Centreon DEM daily to monitor our site performance and swiftly resolve eventual issues. When preparing for sales periods the platform is essential to guarantee stable and smooth site performance under the pressure of increased traffic. This guarantee means we are free to focus on other strategies for improving the business,” says Regis Pennel, Founder at L’Exception.

Peace of Mind and Successful Sales

Centreon DEM is L’Exception’s sole tool for monitoring and improving website performance. The platform is essential for ensuring the best possible digital experience and strengthening SEO. The team benefits from complete visibility and control over every aspect of the site, from high-level overviews to the smallest details. They can also rely on Centreon DEM’s Performance Gurus for guidance and support whenever needed.

With confidence that the site will provide a reliable and optimal online experience at all times, the company can now concentrate on growing the business.
