In just 1.5 hrs 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.
Erwin, the proud Groninger who conquered the Netherlands with all his (technical) page speed and UX optimizations. The collaboration is great!
Very satisfied with the update, Erwin knows what he is doing diving right into matters. This can also be seen in our new WP PageSpeed score of 90+ on mobile.
We enjoyed the in-house training. Erwin combined the session with a high level of knowledge and smart coding solutions! We started optimizing right after the session.
