Advice on further refinements for SEO pages optimization

Thanks for following up on my previous request.

We are planning to further optimize our current website (f1max.nl) in terms of improving linking structure of tags/pages.

Would like to know if planning a session to do so is possible; looking at what we have to address first and how we can improve the current workflow, as to be future-proof so to speak.

Could someone from your end go through our current setup and provide the necessary information?
