Switch back to content based ads, which is what we had prior to the internet. If you have a car related product, advertise on car related websites. Don't try to advertise to a car person visiting a Jazz music site.

I think going back to content based advertising will greatly improve the quality of content on the internet.

The way it works now, the most valuable content is the cheapest content that can get valuable eyes to look at it, which leads to clickbait and low effort content.

If advertisers can only make ad decisions based on the content, quality content will be more valuable.
