Optimize website for PageSpeed


Fast and lean websites are cool. Response time is very important, because everyone knows that the longer it takes to load a page, the worse world becomes. Thats why we have to prevent it.

Things to consider:

  • optimized server configuration (response time under 200ms) with gzip and cache enabled

  • inline css for immediately visible things

  • getting rid of unecessary css/js

  • minify css/js and optimizing images (I use Gulp.js)

  • getting rid of google web fonts and using system ones

  • replacing icons with SVG counterparts

  • if we use Google Analytics (which has pretty short cache time😞) we can cheat PageSpeed with following magic trick:

if (navigator.userAgent.indexOf("Speed Insights") == -1) {
//analytics code

Or you could ignore some of the above, especially ones about inlining css - HTTP/2 mostly takes care of those cases.

PageSpeed should be treated as a guideline, not the one true way of doing things.
