If your WooCommerce store feels slow (or isn’t scoring as well as you’d like in PageSpeed Insights), there’s a good chance third-party scripts are part of the problem.
Most eCommerce stores rely on one or more of: pixel tracking, chat widgets, review carousels, video embeds, A/B testing, Facebook tracking, Google Analytics, and heatmaps. And there are many more examples like these! Each one of these tools adds extra JavaScript to your pages, and those scripts often run on the main thread, slowing your site’s response time to shoppers.
The good news is you don’t need to remove these tools to speed things up. In most cases, stopping non-essential JavaScript from loading until the shopper shows intent (for example, tapping, clicking, or scrolling) can solve the problem.
In this guide, we’ll walk through a practical checklist to reduce the impact of third-party scripts on your WooCommerce store without sacrificing any sales-generating features.
