I work for a company that has a website with incredibly slow page load speed. (The average for the site is around 8 seconds). We use GA for our analytics so for a person to register as a bounce the site must fully load the page. Obviously lots of people will be bouncing in that time before it loads, is there a way to see how many people leave during this time or at least an estimate of how much data we might be missing?
I'm not able to make any changes to the websites code
The business seems blissfully unaware of the issues caused by the page load and I want some estimated impact numbers to light a fire under them
