The 30-Minute-Guide to a 100/100 Score on Pagespeed Insights and Pingdom

How to get a 100/100 Score in Pagespeed Insights and Pingdom in 30-minutes

A few years ago I wrote a guide on how to get a perfect 100/100 score on Pagespeed Insights, Pingdom and GTMetrix. A lot of time has passed since then. The rules have changed and I’ve learned new, easier ways to optimize my WordPress blog. In this post I’ll show you an updated approach to completely optimize your blog using a few efficiënt, easy to use plugins.

In order to speed up your WordPress website you’re going to need the right tools. Luckily all of these very powerful plugins are free.

  • WP Fastest Cache,
  • Autoptimize,

And if you’re using Google Fonts and/or Google Analytics:

  • OMGF,
  • CAOS.

In my previous post I was convinced W3 Total Cache (W3TC) was the way to go when it came to page caching. Over time I learned that W3TC should be seen somewhat as a pro-package. If your blog is hosted on a VPS or Dedicated Server — which most WordPress blogs aren’t — W3TC offers you the tools to tweak it to peak performance.

However, most WordPress blogs aren’t on dedicated hosting, but rather shared hosting — so am I. The developers already confessed that W3TC’s minification method took up too much resources for these types of hosting packages. So we’ll be sticking to Autoptimize to minify and combine our JavaScript (JS) and Stylesheets (CSS).

Today I will show you how WP Fastest Cache and Autoptimize will make you score higher in Google Pagespeed Insights and Pingdom.

Installing the Plugins

I assume you know how to install plugins from within your own WordPress installation. If not, click the link. After you’ve installed and activated the plugins through the repository, continue with this tutorial.

  1. Hi, thanks for the article.
    Just a few questions, I bought yesterday WP Rocket cause I saw in different post that was the better plugin to fix the GTMetrix issues,… butnot all of them, and my questions are:

    Do you prefer your free plugins or WP Rocket?
    Is there any way to usu WP Rocket with a combination of some of the plugins of your post?

    Thanks a lot

    • Honestly, I don’t have any experience with WP Rocket. I know WP Rocket offers a CDN Service, which can increase your site’s performance on a global scale. Which is awesome and gives you a score boost on YSlow, because they measure for files served over a CDN. Pingdom and Pagespeed don’t.

      In short, I don’t think one approach performs better than the other. One approach is free :) The other offers a CDN, for a price.

      • Sorry Daan. I must be an idiot. I tried it all again from Step 1 and still have the same page speed. I don’t know why. I still get these suggestions from page speed insights Reduce server response time
        Enable compression
        Eliminate render-blocking JavaScript and CSS in above-the-fold content
        Optimize images
        Prioritize visible content
        Leverage browser caching.
        Can you help?

        • First of all, you’re not an idiot. ;) Now we have that established, let me explain what’s going on:
          Reduce server response time: this could be because of a number of things. It basically means that your server responds slower that 0,2 seconds — a standard set by Google — to serve content to the browser. This could be because of low disk space, slow server CPU’s, an outdated PHP version. Really, anything.
          Enable compression: This is about an external resource (something from Facebook). So sorry, you can’t do anything about this, except disable all Facebook related stuff on your website.
          Eliminate render-block JavaScript and CSS in above-the-fold content: this is explained on the last page of this post. This fixes it.
          Optimize images: this means that images that are loaded are larger in size than they should be. I use Shortpixel for this, but there are many choices to optimize your images.
          Prioritize visible content: this warning will disappear together with ‘Eliminate render-block JS and CSS’.
          Leverage browser caching: This is about external resources as well, so you can’t influence this. If you’re using Google Tag Manager only to implement Google Analytics, I’d suggest using my plugin CAOS. If you’re using it for other purposes, you can’t do anything about it.

          Hope this helps! :)

          • Yes it does Daan. I realise I have Google Tag Manager plus your CAOS plugin so will remove it plus the facebook thing since I haven’t launched as yet…I’ll look at all my images as they must be the wrong size even though I have resmustit. Thanks for being here. Couldn’t thank you enough for your advice!!!!

  2. Hello Daan,
    Thank you su much for your work! This “operation” give my homepages more speed.
    But 5 days after changing this Plugins I saw that Autoptimize changed a lot of my layout. So I disactivated: all fine, reactivated after trying a lot. Start from Zero and at the end it seems to word out.

    NOW I can see only one errore in the visualizzation, when I’m on BROWSING with the Internet Explorer (the other browsers seems ok).

    I made a screenshot and put it here:
    where you can see that the TEXT in the “testimonial module” of Divi is shown outside, one letter under the other.

    Can you help me in this?
    (a beer and a Pizza is waiting for you i Italy, and your family shure!)
    Greetings, Martina

    • Hi Martina,

      I haven’t heard of Autoptimize breaking the layout before. Are you sure it isn’t a caching issue within Internet Explorer? Have you cleaned the browser cache?

      Then again, Internet Explorer is a very old browser — it isn’t even maintained anymore and it’s replaced by Edge. So I wouldn’t worry too much about your site’s looks in that browser. Barely anyone uses it anymore.

      If you really want to fix that issue, I’d suggest you just add some CSS to fix it for IE specifically. You can add a styling block to your theme’s header (Divi offers a custom head (and footer) code option within the theme options, I believe), containing the following:

      <!--[if IE]>
          /* Your CSS here */
  3. Sorry for the delay in answering you. Now I tried again with and without Autoptimize and I cannot find any more errors. Sorry for wasting your time.
    Thanks and greetings :-) Martina

    • Now I understand:
      the last to options in Autoptimize-options: if I activate them (save script in a static way and optimize also for other users – should be the translation) I CAUSE problems. If they are DEactivated: all fine!

  4. Sorry Daan, I come back again for this problem that seems to be a GHOST PROBLEM:

    it is not always like that.

    Today it was on: browsing with FIREFOX. The last button (shampoo) on the left site in this row was like 80% SMALLER!

    I deaktivated Autoptimize: it works perfect (in a cleaned Browser) and than reactivated it. This time the visualizzation problem does not come back.

    I think there is no sense to try with CSS (not thinking of the fact that I do not know CSS) because the GHOST PROBLEM come one day here, one day there….

    Some days I deaktivated Autoptimize because of this but yesterday I put it again on all my 8 homepages because your tipps REALLY makes a SPEED DIFFERENCE!

    Any ideas?
    Thank you, Greetings, Martina

  5. Hello Daan,

    Great article. I just followed your tutorial and it brought some interesting speed developments on my website. But still, I am getting warnings in Google Page Speed Insights against analytics code. I installed your plugin and entered the tracking ID. should I make any modifications there?

    Waiting for your reply,

    • Hi Manoj,

      I’ve ran your site through Pagespeed Insights and appearantly you’re still loading analytics.js externally. It states the source is: /analytics.js ( This isn’t created by CAOS, because CAOS copies the file to your localhost. Whichever plugin or head-code is adding this to your website, you can remove it. Cause CAOS is taking care of it now :)

  6. Hi Daan, i just wanna thank you for this detailed guide. It completely skyrocket me site enormously. Am not getting 100% yet in pagespeed insitghts, but i completely loved the improvement it made.

    At first, after applying all settings, Me site broke layout. Then i reverted all changes and enabled them one by one. Miraculously, the site came back to normal and faster after enabling all the guide here. I dont know why or how but i just love it. Thanks again.

  7. Thanks for these tips but, Autooptimize Breaks my website recently. it was working great. i posted it on Support too but no response. Can you help me with Analytics and fonts? i dont know how to remove the external analytics.js file. i dont know from where it loads and for Fonts i downloaded Fonts and updated scripts. but how to do the after work? how to remove the scripts? I am using “HESTIA” Theme.

  8. Hi Dan,

    Thanks for the advice, has helped but not getting anywhere near 100%.
    Inserting the script from broke image layout and lazy loading on the site.
    But it looks like Google have changed the rules again as your site only gets ~72/85

    • You’re right! I guess I should also add: don’t use images, don’t use any 3rd party Javascripts. You know what, the fastest sites are text-only with a little bit of inline CSS-styling, and it gives you that real ’90s feel. Awesome! ;-)

  9. Hi! Thank You very, very much for this guide. I tried a lot of ways to optimize the speed of my webs and this method is the one that has the best results in all the webs I tried and there are no issues! Thank You for this and your plugins!
