Instead of linking vps to the affiliate link it would be better to add something below it like “We recommend hetzner " which would be the hetzner link and at the bottom of the page add " we may earn compensation for affiliate links” or something like that. I would expect clicking vps to go to something explaining what a vps is, not to a certain provider.
