How our script affects website performance

Understand how our script affects the speed of your website and things you can do to improve it.

Updated over a week ago

In order for us to integrate with a website, we require you to include to a JavsScript file that tracks which pages and products your customers are visiting so we can use this information in your triggered campaigns. This script is loaded each time a page is viewed on your site.

We're conscious of performance and our script has been designed to be fast. All unnecessary characters, such as spaces, have been removed to decrease the size.

Trace bar

If you're visiting the page with the trace bar on (the red bar at the bottom of the page), it forces a formatted version to be displayed. The file is loaded from a CDN for maximum speed.

The script also uses the both the async and defer attributes, which means it isn't loaded until after the page has finished rendering. This is so it doesn't block any other elements loading and shouldn't affect the speed to display the rest of the page.

We also set a cache timeout on the script so visitors avoid having to download it on every page they visit.

The time period must be kept relatively short in case of script updates.


How to audit your page speed

If you want to explore performance further, we have articles and a downloadable checklist that takes you through the points you can review across your site to help reduce your loading times.

Additionally, check out a webinar we ran where one of our customers provides their real-world experience with optimization and their tips to make your site as fast as possible.
