- static banners (non blinking, no transitions, esp. no vertical transitions that are designed to force you to lose focus – I've come for the content, not the ads)
- no tracking that exceeds maybe, if you have seen the campaign already. Preferably hosted by the website (who is responsible?).
- also, no targeting. Ads once were supposed to be consumer information. Public information is meant to be public, so I would enjoy leaning about what is out there (in the big world). Not just being reminded of what I bought last month, over and over again. Consumer products are part of (ephemeral) culture and I'd like to be part of it. (Reminder: you can always select/target by content and context, not just per user profile. This is technically feasible, as demonstrated by earlier versions of the Web.)
(This is also valid for recommendation and content presentation algorithms of all kind: I generally feel like desperately gasping for air, while being strangled by algorithms that only allow for an ever narrower bandwidth of the ever same. – E.g., is it really true that there are just three videos uploaded to YouTube per week? How do they make a profit? So you say, there are millions? How I'm not going to see them? Even a text search is littered by out of context reminders of the ever same…)
– moreover, ads should be more expensive for the advertising party. There should be less in total and the revenue for content providers should be greater (remember the thriving blog scene, we once had, when bloggers could make a living?)
(In other words, role it back to the early 2000s and I'm fine with that. Essentially, before Google ads went on steroids.)
