Maybe Google's just having a laugh, but this business of speeding our sites up for mobile is taking up far too much time. Thanks to all the kind contributors in the WA community, I have greatly increased my page speed and load time but on Google's PageSpeed Insights tool, it's still only at 70 for mobile. It keeps giving me the render-blocking, etc. message. Sadly when it comes to coding, I am definitely "not your man" so I need to rely on plugins.
FYI, I use W3 Total Cache, WP Super Minify - these have helped and I tried WP Fastest Cache also.
