how to optimize these problems

hey @assemfoad , didn’t see your post here earlier.

what you could do is use AO for CSS as well (you now seem to be using WP Fastest Cache for that) and then look into the “inline & defer” option (more info in the AO FAQ).

lazy-loading images would help as well, AO 2.5 (in beta now, you can download it from https://github.com/futtta/autoptimize/archive/beta.zip) has a lazy-loading option.

and finally switching to webp (which is also in AO 2.5) could help improve your scores too.

but … 1.8s fully loaded time is not bad at all. and eventually “time” (time to first byte, time to start render/ paint, onload time, fully loaded time) are the metrics that matter most ??

hope this helps,
frank
