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 challenges are there when using Magento and Hyvä, how to translate Lighthouse and to master Core Web Vitals.

In-house and online

Whether it's in-person or online, my consulting, training, and audits are always interactive, tailored to your needs, and practical.

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;

    • 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.
