Making progress but still severely lacking on mobile. I’ve tried Google search and YouTube.

I'm getting somewhere. I've uploaded imagify but for some reason not all images seem to be optimized. I wonder if the initial image uploaded was too big to begin win.

I also have WP rocket now and enabled the clear css option and Java option deferred per page insights.

Whats a good size "width X height" in pixels. For images for blog post images and customer reviews.

My goal is to get performance in the green. And get accessibility and seo to 100.

I have zero website knowledge and have been learning this as I go with YouTube and google.

I've followed the recommendations on page insights but not all of them seem to be working.

I'm hoping to rank higher on Google search results locally.

Appreciate any insight.
