There are certain recommendations from Google Page Insight Speed reports that are not possible to be handled from code (and this applies for any website that offers you services like Google Maps, IDX support and so on).

– while you have a theme with third party JS (Rev Slider, Google Maps)
Eliminate render-blocking JavaScript and CSS in above-the-fold content – is impossible to be 100%

Example: Trulia

This message means that it will be faster for a site to load all the javascript at ones and not loading many files one after another. This message is a theoretical one , but for any wordpress theme is impossible to apply it.  There is no technical way we could put all of our js code in a single file . For example you need to load google map api (which is separate) then after that load our google code.

Also consider that you have plugins that each comes with their own js/ css files.


Minify is a process that basically encodes files. Theme files can be minified from theme options – help

Site speed

External resources about minify –


Enable caching for third party – Google Maps – is not possible because google doesn’t allow it.


Optimize images is something each person does as images are added by each client. Gimp desktop app is a tool to optimize images (for example)


On items like Remove query strings from static resources–  there’s nothing to do since the variable detected is the script version from wp. And it will gain no actual speed


For the server you have 2 important things you can do

Specify a Vary: Accept-Encoding header

Enable gzip compression


on Minimize redirects

If you are using 2 tpes of url – with www and without www.   Use only the one with www


Use a cache plugin like wp-fastest-cache – besides cache it also does mimify js and css
