About:

It's a brilliant form of arbitrage, people click on a link thinking they will find what they need, but they see a low quality article plus some relevant ads, so they click on an ad. They could have clicked on the ad at Google, but instead they do it on a content farm, so the ad revenue is basically click arbitrage where the content farm has found a better way to position ads than the search engine, so they get traffic from the search engine and monetize that traffic.

Whether this is productive is another question.
