Just as an example: there's a site Tom's Guide that monetizes in an article here: https://www.tomsguide.com/best-picks/best-vpn

The site is huge and they're doing affiliate marketing on multiple pages, not just my example link.

Also: The articles are also authoritative, authentic and not mere blogspam. They explain everything in detail and offer insights; the affiliate links are not the sole purpose: they want to write a blogpost too!
