PageSpeed Insights Issue

Hey everyone, improved page speed on a project today but one issue seems to be difficult to solve. I’m using the awesome nuxt GTM module and loading it like this from nuxt.config.js:

gtm: {
    id: '<my-ID>',
    pageTracking: true
  }

Google Pagespeed Insights tells me under “Remove unused JavaScript” the following items:

/gtm.js?id=<my-ID>(www.googletagmanager.com) | 26.2 KB | 12.5 KB
/analytics.js(www.google-analytics.com) | 18.6 KB | 6.7 KB

Is this caused by gtm module (which I don’t think) or by GTM / Analytics / Pagespeed Insights itself?

Maybe you can help me, thank you very much in advance and I really appreciate it!

@bart have you tried setting the scriptDefer to true? This should hold the loading of the GTM script until all other scripts are ready. It works for me.

And since I also enabled pageTracking. In GTM i also make sure the tag is fired during the “nuxtRoute” custom event instead of the standard “Page View”.

Here’s my settings btw:

gtm: {
  scriptDefer: true,
  enabled: process.env.APP_ENV === 'production' ? true : false,
  id: 'GTM-XXXXXX',
  pageTracking: true,
}
