Advertising remains the oldest monetization model in publishing, and it's also one of the most misunderstood. This section covers how display ads, programmatic networks, and direct-sold placements actually pay out, including the fill rates, CPMs, and ad-blocker impact that determine whether an ad-supported site or channel is sustainable.
We break down the difference between RPM and CPM, why programmatic revenue can vary wildly month to month even with stable traffic, and when direct-sold sponsorships make more sense than running a network at all.
We also cover the operational side that most explainers skip: how long it actually takes a new site to qualify for premium ad networks, what a realistic fill rate looks like outside of peak advertising seasons, and how ad-blocker adoption rates differ sharply between niches like finance and gaming.
If you're trying to figure out whether ad revenue alone can support your site or channel, or how to structure a mixed model, this is where we cover the actual math.
