Pagespeed training in a nutshell

Unlike a webshop's pagespeed audit, a pagespeed training is not specific to a use-case. As UX is about how browsers will handle your code, the frameworks you use is subsidiary.

Nowadays better known as Core Web Vitals. I will cover perceived performance to technical UX, including third party contents. For example:

  • CDN or not to CDN

    Some webshops still put full trust in CDN and Rocket Loader solutions. This doesn't always works nicely together with HTTP/2, cache partition and Core Web Vitals.

  • Non-technical?

    Not an issue. I will tailor the pagespeed training to the knowledge of your in-house SEO, UX or CRO team so they will learn how to collaborate with developers.

  • Already tried it all?

    Are developers telling you that the webshop's pagespeed can't improve further due to hosting, platform, framework, GTM or your design?

  • Page Load Time

    Still thinking it is about Page Load Time? It never was, but we did not had a better way of investigating impact on UX and conversion.. until Lighthouse.

Agency tailored pagespeed training

A pagespeed training is tailored to your agency (being SEO, UX, CRO or technical). After a training you know:

  • how to interpret Lighthouse analysis, Core Web Vital data;
  • start to focus on the right metrics and real user experience;
  • how browsers reads your code and tricks & best practices for 3rd parties and GTM;
  • change your mindset and get to apply best practices in the long run.

For whom

While mainly invited by dev-agencies and merchants, I am also invited by SEO, UX & CRO agencies and in-house teams since pagespeed is now encapsulated in Core Web Vitals.


From pagespeed to technical UX: learn what Amazon to Zalando are doing wrong, how to translate Lighthouse and to master Core Web Vitals.

In-house and online

Frequently asked questions

Before starting

  • I'm invited by development agencies, sometimes platform specific such as Magento, Shopware, WooCommerce. But I'm also getting invited by SEO, UX and CRO agencies. Sometimes even a team of specialist within an e-commerce business or agency.

    Obviously, the more technical your team is, the more technical the training session will be. If your team is a mix of different specialist, I try to keep everybody involved.

  • When your agency is focussing on online business or even e-commerce, than I'll be sure to tailor my training sessions to your (team's) knowledge. Before kicking off a training session, I will ask the attendees about their backgrounds.

    This means you don't need any specific knowledge.

  • This is the fixed list of topics, where the elaboration per topics depend on your type of agency or team:

    • Introduction into user perception
    • PageSpeed Insights (versus other toolings)
    • (Core) Web Vitals
      • First Contentful Paint;
      • First Input Delay;
      • Largest Contentful Paint;
      • Cumulative Layout Shift;
    • CSS
    • JS (including Time to Interactive and Total Blocking Time);
    • Fonts
    • Images
    • Caching & compressing
    • Browser
    • Network (latency) and CDN
    • Headless, PWA & AMP
    • Server (side)
    • Third parties
    • Identifying
  • Sure thing, although I'll have a list of topics which usually will be part of the training session (see previous question). Do let me know if there are any topics that should be emphasized, for example:

    • (determining) technical anti-patterns when being a development agency;
    • perceived performance when being a UX team or agency;
    • Core Web Vitals when being a CRO team or agency;
    • Google Tag Manager for an SEO team or agency;
    • Third parties for marketeers;
    • et cetera.
  • Off course, the goal is to let pagespeed become a prospect instead of an afterthought and thus to not only have me sending information, but also to start the dialogue. Even during the training.

    So be sure to send me any questions beforehand, which will be answered or discussed during the training.
