Context

Cléo 3000 was founded in 1970 and offered women’s ready-to-wear clothing at the time. The brand was renamed Celio in 1978 and then specialized in men’s clothing. This brand is now present in nearly 50 countries with more than 1,500 stores on all continents. The e-commerce platform was created in 2009, has offered click-and-collect since 2013, and also store-to-web since 2016.

Digital thus occupies a predominant place for Celio, which passes all its traffic and resources through Fasterize, in order to ensure both the loading speed of its pages and the stability of its infrastructure. Thus, the Front-end Optimization engine has become essential for the technical stack of Celio.com !

Celio had previously identified CDN solutions to improve its loading times, but Fasterize caught the attention of IT teams because of its “Next generation CDN” dimension.
Indeed, the solution allows both to bring content closer to users, and the automatic and intelligent application of good practices and webperf techniques to speed up web pages… all for a more advantageous budget .

The SaaS solution has thus become one of the pillars of Celio.com’s infrastructure , both to optimize the Front-end and to guarantee the availability of the site and save time for the teams.

Goals

Monitoring webperf KPIs

Since the 2015 redesign, Celio has implemented Fasterize to reduce the loading time of its site pages. During a new redesign in 2019, improving loading times remained a priority, and it is thanks to the automation of front-end optimizations, among other things, that performance and stability objectives are maintained.

Now that the solution is perfectly integrated into the work tools of the digital production teams, the objective is to get closer to the business teams to continue the evangelization on webperf issues.
Regular points are planned to take stock of the site’s performance in collaboration with their dedicated Customer Success Engineer, and thus continue the promotion of the automation of front-end optimizations.

The impacts are visible for the business , the availability and security of the merchant platform, and this also helps to relieve the IT teams .

Deployment

First, Celio.com conducted tests on its Indian catalog which was then in the launch phase. This test validated the impact of Fasterize’s CDN and webperf optimizations.

The results were clear and the decision was made quickly: the solution was deployed in less than 8 weeks on the new version of the site. Also, Celio benefited from dedicated support to finely adjust the parameters, and thus reduce its Speed Index by more than 40% on average!

Support

Sharing webperf expertise

On a daily basis, production teams use the platform dashboard directly to clear the cache, manage redirects, etc. An autonomous use that allows them to fully take ownership of the tool.

Celio also relies on Fasterize’s expertise to develop its skills in web performance , and to guarantee the loading speed of pages and the availability of sites with each evolution. Indeed, each modification of the site may require new adjustments to optimizations, and Fasterize experts remain present for IT teams in order to get the most out of the engine if necessary.

The links are thus strengthened with each new project which involves webperf aspects.

Our favorite features

The CDN which optimizes the distribution of content in all countries where the Celio.com site is deployed (France, Spain, Italy, Belgium), and which also secures the infrastructure.
The advanced cache system (including SmartCache), which also relieves Celio.com’s servers and improves performance by reducing the number of requests. It distinguishes between static and dynamic elements of a page so that it is displayed quickly, even if the content is personalized. Thus, a page can be optimized despite the presence of dynamic content, which is inevitable on an e-commerce site.
Image lazyloading , which allows product pages to load much faster by displaying elements above the fold first. This ensures users see the content they came for quickly, which helps drive conversions.

In terms of organization, development teams save a lot of time by delegating webperf optimizations to the Fasterize engine. No need to redo optimizations with each modification on the site!

Peak load management made easy

Fasterize also allows the Celio.com site to maintain the load during periods of high commercial activity , during which the site welcomes several thousand visitors simultaneously.

Absorbing traffic peaks is a major challenge for e-retailers, especially during the holiday season, sales, or any promotional operation.
Thus, the Traffic Limiter is also one of the features that Celio activates to relieve its servers and remain available during busy periods on its site to secure sales .

The impact of Fasterize is clearly visible on webperf KPIs, and therefore on the perception of speed for Celio.com customers.

They testify…

We serve different countries and we need to bring content closer to customers to offer them the best possible experience. This goal is achieved thanks to Fasterize's CDN. We also have an omnichannel strategy that integrates our desktop and mobile merchant sites. Knowing that 60% of our traffic comes from mobile, we absolutely have to be fast on this device! In addition, we provide tablets to customers in store, and the catalog pages must be displayed as quickly as possible on this device too. These in-store tablets are a source of captive traffic that has every chance of converting; and for this, we need the pages to be displayed quickly, using a powerful caching system, especially for images.
