How can I improve my site's LCP, more specifically the load delay?

Hi there,

I have tried to make several improvements to my side. The LCP is the bottleneck of the page performance. This counts for all subpages.

I have reduced the main.css stylesheet by removing unused css and also set the priority of the LCP image to high, whereas the other non-critical resources are set to lazyload, fetchriority low or in case of scripts defered.

Nevertheless I noticed in my network tab that especially resources of third-party apps have highest priority. I presume this is the reason for render-blocking and causing the load delay.

But maybe I am on the wrong track…

Looking forward to hints!
