3. Increased Bandwidth Usage

  • Each third-party image added to your webpage requires the user’s browser to download the image data from the external server.
  • If you have multiple third-party images on your webpage, each image requires a separate HTTP request to fetch it from the external server. These requests contribute to the overall bandwidth usage.

How to Reduce the Impact of Third-Party Images?

There are a few things you can do to minimize the impact of third-party images/code on website speed

1. Optimize Images from Third-Party Sources (Social Media, Apps)

  • You need to understand the different options for images available to the third party (like social media).
  • While uploading images on Social Media and using that feed for your website, consider the impact of the image payload on your website while uploading on Social Media.
  • If these images are not changed frequently then we recommend uploading these images on shopify rather than using it from the social media feed. ensure that your images are high-quality and of efficient size, or redesign your website section so that third-party images can be used more effectively.

2. Optimize Third-Party Images/Block

  • There is no scope for third-party images present so we do not have control over third-party images.
  • Rather than using HTML sections from social media/ third-party websites, fetch them (if legal and with no copyright infringements) and use your own defined HTML and CSS. By using your own HTML CSS, you will be able to apply lazy loading and picture tags simultaneously. as a result, the image payload for the above fold will be reduced.
Overall, it’s important to be mindful of the impact that third-party images can have on the speed of your Shopify store and to take steps to optimize them as needed to ensure the best user experience.
