The site has a bunch of redundant SEO-ish posts, most dated yesterday, on typical affiliate topics like VPNs.

For example, on VPNs, all but one of of these is dated June 3rd, one dated June 4th:

  https://kevinhq.com/my-experience-with-protonvpn-free-plan/
  https://kevinhq.com/my-experience-with-protonvpn-basic-plan/

  https://kevinhq.com/do-i-really-need-vpn/
  https://kevinhq.com/things-to-know-before-using-vpn/

Another example is hosting, which includes 6 posts dated yesterday, 3 of which have titles suggesting it's advising which hosting provider to choose: https://kevinhq.com/tag/shared-hosting/

ProtonMail's services are potentially important, but this site doesn't seem the most credible source of information about that.
