How to Improve Your TTI Score?

Performance best practices are specific to the Shopify site and can be implemented by optimizing image loading, minimizing render-blocking resources, and leveraging browser caching.

Minimize Main Thread Work

Optimizing time TTI on your shopify site requires minimizing main thread work.

Reduce JavaScript Execution Time

JavaScript plays a significant role in website interactivity but can also cause delays. Minimize the amount of JavaScript executed during page load by deferring non-critical scripts. Move scripts to the bottom of the page or use the “async” or “defer” attributes to prevent blocking the rendering process.

Remove Unused Javascript and CSS

It is possible for JavaScript and CSS files that are not being used to block the rendering process, forcing the browser to wait until the files are loaded and executing and then proceed. By removing unused files, the browser is able to render the page more quickly.

Improve Server Response Time

  • Optimize third-party apps and scripts
  • Distribute static content worldwide by using a CDN, such as images, CSS, and JavaScript.
