Please give more weight to a page's ad load of search results in your ranking algorithm.
This would naturally push down crappy content farms.
Searching for "Vanilla Cookies" for example, the top result is just unbearably too many ads.

The ad load for this page alone should be enough to keep it out of the position 1.
Google is incentivized to put sites with GAN ads high in search results, so they don't do this. It could be a real differentiator.
Sites with high ad load, like the this one, (https://cloudykitchen.com/blog/classic-vanilla-cookies/) should not show up in search results.
