well, you want to make sure AO does not have to re-minify for every request (because the time it takes + cache size impact). to do that you need to either disable “aggregate inline JS” OR keep that on but exclude the inline JS that has changing variables. In your case an example of that “cache-busting inline JS” is the JS that is included in the “contact”-widget, which reads;
var t=[61,-1,98,-66,170,-56,157,-55,116,-82,191,-94,199,-91,207,-96,154,-116,151,-94,151,-92,130,-95,144,-95,144,-85,123,-88,137,-88,136,-77,115,-80,129,-80,134,-75,113,-78,135,-80,139,-101,136,-79,136,-77,115,-80,129,-80,134,-75,113,-78,132,-80,139,-101,136,-87,135,-87,146,-108,143,-86,141,-82,120,-85,134,-86,139,-80,118,-83,132,-82,132,-73,111,-76,125,-75,124,-65,103,-68,120,-66,125,-87,122,-73,121,-64,123,-85,120,-71,119,-70,129,-91,126,-77,125,-77,136,-98,133,-84,132,-79,138,-100,135,-78,133,-74,108,-46,129,-13,130,-13,127,-95,206,-96,211,-179,280,-179,289,-257,358,-249,346,-241,349,-316,376,-329,426,-364];var toAppend='';for(var i=1;i<t.length;i++)
{toAppend+=String.fromCharCode(t[i]+t[i-1]);}
document.getElementById('8457dbbd0103a28122f0f5ddf55bac72').innerHTML=toAppend;;
so to exclude that block of JS from optimization, you would add toAppend+=String.fromCharCode
to the comma-separated list of JS optimization exclusions. and then you should check if you have other cache-busting JS and again apply the same principle.
