Hello, I’m currently assessing my site’s SEO performance using Google PageSpeed insights, and one of the apects of my page I’m being told to improve is using passive listeners to improve scrolling performance:
Can anyone inform me where or if I can actually change/edit this? Or if this is something that Hubspot sets automatically? Thank you in advance.
The report is showing jQuery as being the source. jQuery currently does not have support for passive event listeners. It’s been an ongoing issue for a several years now that they hope to implement a fix for in version 4.0 (but who knows when that’ll be released).
There’s a proposed workaround you can see here - https://stackoverflow.com/questions/60357083/does-not-use-passive-listeners-to-improve-scrolling-performance-lighthouse-repo - you would need to add the code into your theme/templates after wherever jQuery is being loaded.
