Situation and Background

The Carmana Hotel & Suites website was underperforming due to a lack of technical optimization.

We determined a primary goal of improving Core Web Vitals – along with other digital performance metrics – through the redevelopment of the hotel’s website.

Secondary objectives included implementing proper eCommerce tracking, improving user friendliness and increasing rankings, which would put Carmana Hotel & Suites on the path to a boost in their bottom line. 

Key Factors: 

  • The new website would be headless in an effort to showcase immediate improvement in key performance metrics.

Tiled pages of Carmana Hotel & Suites website


TravelBoom redeveloped the Carmana Hotel & Suites website on a headless configuration in an effort to decouple, or remove, the CMS from the front end of a website, offering a content-first approach that utilizes an API to access and display content. 

We were already aware of the advantages of a headless website, with overall performance at the top of the list. A headless design removes concerns of caching, database optimization and image optimization. More specifically, with a headless solution, the page isn’t actually changing or being reloaded, but instead, content is shifting, which translates to faster load times – aligning with our primary goal.

Carmana Hotel & Suite’s website was created using both NextJS + WordPress, with the CMS hosted on WPEngine and the front end hosted on Vercel.

Below are a few recommended best practices to ensure web vitals are healthy:

  • Avoid chaining critical requests
  • Keep request counts low and transfer sizes small 
  • Avoid large layout shifts 
  • Avoid long main-thread tasks
  • Reduce JavaScript execution time
  • Minimize main-thread work 

We’re now starting to see strong correlations between fast page load times and higher search rankings.
