Shoe Carnival

Shoe Carnival Outperforms 98% of Sites with an Instant Website on Layer0

Shoe Carnival, one of the nation’s largest family footwear retailers, offers a broad assortment of dress, casual, and athletic brand name footwear for men, women, and children. With 80% of the retailer’s traffic coming from mobile and a proprietary front end that was both slow and challenging to develop, Shoe Carnival was looking for a proper solution. The retailer found what it needed with advanced web tech for sub-second websites through Layer0 by Limelight and AWS.

“On Layer0, we have better speed and conversions. From a developer’s standpoint, we have far more flexibility and no restrictions.”

Tyler Drone, Sr. Manager of Digital Development - Shoe Carnival

Instant-loading pages on Layer0

ShoeCarnival.com went from 3.4-second first-page loads and 6-second browsing transitions to both being 1 second or less. On Layer0, first loads are 70.5% faster, with a 1-second median load time. More importantly, subsequent page loads are cut by an astonishing 92%, down to 500ms.

“The speed was so much faster than a lot of the things that we were comparing it to. This was unique to this platform (Layer0).”


Layer0 makes instant loads possible every time, with little to no developmental headache. “The platform is more flexible, user friendly, and takes all the guesswork out of deployments and caching,” stated Drone. Shoe Carnival has full control over caching and traffic routing on Layer0. This, along with the platform’s CDN-as-JavaScript, which caches dynamic content at the edge and streams it to the browser before it is requested, ensures that ShoeCarnival.com delivers an exceptional, instant experience.

Instant SEO

The faster the site, the higher it ranks. Shoe Carnival is a great example for that, as it outranks the largest names out there, including Amazon, with its sub-second website.

On Layer0, ShoeCarnival.com’s mobile Lighthouse score skyrocketed. Based on our analysis of the performance scores of the leading 500 US internet retailers, ShoeCarnival.com outperforms 98% of the leading eCommerce websites.

A website’s Lighthouse score essentially shows you how Google perceives that site in terms of speed. In turn, speed impacts the site’s organic ranking. Search engines are favoring faster websites in the ranks, and ShoeCarnival.com is now outperforming and outranking the biggest names out there, including Amazon, Zappos, Nordstrom, along with other multi-billion dollar competitors for key phrases.

Layer0 doesn’t only enable speedy websites, it also simplifies and accelerates the developmental process.

Instant made simple

From a technical perspective, Layer0 simplifies the process of building, testing, optimizing, and running large eCommerce websites. Shoe Carnival can now add and amend functionality and endpoints, in a fraction of the time it used to take them.

Layer0 puts the code in the center of your workflow. It simplifies the developmental process and accelerates testing and feedback cycles with automated tests and staging URLs for every branch created. Once live, Layer0 lets you easily monitor your site’s performance and caching in various levels of granularity, so that every optimization effort is maximized.

Drone and team are able to squeeze every millisecond out of every speed optimization effort through the use of a combination of advanced technology, built into Layer0. These include built-in auto-AMP and Server-Side Rendering support for portable frontends, predictive prefetching and CDN-as-JavaScript to deliver a 95%+ cache hit ratio for dynamic content at the edge.

From a general ability to add or implement new functionality, hands down Layer0 is much easier to work in.


***The whole is greater than the sum of our parts. Many of our client case studies and products were originally part of Limelight, Layer0 or Edgecast. Limelight acquired Layer 0 then Edgecast to become Edgio, the complete platform you have today, so we’ve aggregated those case studies in a single library.
