Affiliate ads may work well for narrow topics, but you are not going to be able to replicate the contextual ad earnings for larger sites. You have a lot of management overhead, additional payment risk, advertiser legal risk, and so on.

This is how Google is keeping their revenue moving up as desktop usage drops. It is a combination of fucking around with the Adsense style (more clicks) and advertisers (packaging tablet with desktop, now lumping in search with display "select.")

Adsense ads might be ugly, so is display. Auto-playing video ads are even worse. If your business model relies on advertising, either take it our build your own ad platform (some companies have done quite well with this, like Indeed and PlentyofFish.)

Affiliate networks (eg Commission Junction or LinkShare) solve pretty much all of the problems you mentioned.

It's a large business now, and can cover broad and narrow topics. Major affiliate networks can't compete with the scale of AdSense, but then no other ad network can either.
