The training is valuable for the whole team. No standard lists, but real practical knowledge that you can apply immediately. We have applied the acquired knowledge directly to our customers with great success.

Tjitse, certified developerVendic

We had in-depth study of the Core Web Vitals. Through an interesting session, our knowledge has been supplemented with developer insights. Erwin combined the theoretical aspects with many practical tips.

In just 1.5 hours he covered so many different aspects of frontend optimization. I suggest his training and consultancy for other agencies as you will become a 100% PRO in speed optimization.

In terms of SEO, I have a high standard. Working together with our devs, Erwin got us past Core Web Vitals and putting our SEO and UX high within our niche.

Got up to speed by Erwin about the CWV. Erwin is capable of explaining this technical matter in a comprehensible way, including the link between metrics and real UX.
