Google Ad triggers

I always find it incredibly interesting what verbiage in my post trigger the relevant Google ads on the right. Of course they are trying to sell you something, but it’s always interesting how it picks up on the words or phrases it thinks it can monetize. For instance, overnight ALL my ads turned into “diet” ads the moment I posted the word “diet” in a previous post. It will be interesting if a STRONGER word or phrase will break that hold that the word diet now has on the ad producer.
