Eliminate render-blocking JavaScript and CSS in above-the-fold content
Your page has 2 blocking script resources and 1 blocking CSS resources. This causes a delay in rendering your page.

Remove render-blocking JavaScript:

  • https://script.ioam.de/iam.js
  • https://heise.nuggad.net/rc?nuggn=777637131&nuggsid=1216322088&nuggtg=m.web.heise.de%2Fhomepage

Eliminate render-blocking JavaScript and CSS in above-the-fold content
Your page has 16 blocking script resources and 3 blocking CSS resources. This causes a delay in rendering your page.

None of the above-the-fold content on your page could be rendered without waiting for the following resources to load. Try to defer or asynchronously load blocking resources, or inline the critical portions of those resources directly in the HTML.

Remove render-blocking JavaScript:
