I’ve found that Brave Ads will depend on your search history and category likes for ads shown (i.e., personal finance, personal finance-investing). I often like the Ads I’ve been shown to let Brave know I want to see more of the same. Like this:
Also, if your VPN puts you in another country, Brave can’t effectively share ads pertinent to you. That devalues BAT, as the ROI for advertisers is lower.
Be honest with your interactions with Brave, and use a VPN only when you need it. The more Brave can target ads to you effectively, the more successful our community (ans BAT value) will become.
