My site speed is slow, how do I fix this issue?
My site speed is slow according to https://developers.google.com/speed/pagespeed/insights/ and WA.
I have EWWW Image Optimizer installed.
It says these are the main reasons:
-Serve images in next-gen formats
-Eliminate render-blocking resources
-Remove unused CSS
-Reduce server response times (TTFB)
Does anyone have any idea how to fix this issue? Thank you!!!
