A combination of ads and referral links. Ads are not Google Ads (or similar), but sold directly, no middle-man.

The business very starkly displays a core truth: if you really know how to do SEO, you will run your own websites instead of selling "SEO services".

Running your own websites works in some niches. Very crowded ones, probably.

In others , if you don't have a well run business with a competitive offer, SEO won't help much.
