A thought:
When you click on an ad you then have the option of taking a short quiz about that company/product.
I imagine it would be like the short quizzes offered on Coinbase that reward you with tokens.
Reason:
Advertisers want viewers to UNDERSTAND what they are offering and to FOCUS on it. If users take a short quiz, their attention and retention of the advertised product would increase greatly, increasing the likelihood of a sale. Users would be awarded extra BAT for taking the extra time and effort to learn and take the short quiz.
