Privacy-focused browser Brave has also been listening to consumers, with their permission of course.  They found that 70% of survey respondents find it creepy when they see online ads related to previous Web searches, and 81% would reward brands that gave them more control over how many ads they see.  Brave also ran a test that found ads served in an opt-in environment had a positive impact, but I didn’t see results compared with ads in a conventional environment.  

In partnership with attention metrics provider Adelaide, The Trade Desk is now offering high attention inventory to advertisers. Attention — often based on reactions of opt-in panels to ads — is now competing with viewability as a valued attribute, and is being used to complement contextual metrics. Attention has been used in the past to test ads once they have been published; now it’s entering the pre-bid space.
