How to Optimize Images for Faster WordPress Websites

Hi, thanks a lot for the video. I've implemented all the parts of the SG-Optimizer plugin. However, my website is still loading very slowly, especially on mobile devices. Your advice would be appreciated!

Thanks for the video, I'm dealing with this now. Looking for a solution is tough going, but webp is helping. Maybe you could do another video explaining how to pre-load fonts and avoid showing invisible text? Also looking to pre-load LCP image, but no idea how it is done.
You seem like you have a good grasp of handling adding code- I am still trying to learn the basics here. I don't even know where to add/edit for best results using WP or the actual HTML header. I'm running Autoptimize with some fleeting success, but willing to give SiteGround a go.
Thanks for the helpful video... Subbed!
