If you use Facebook (FB), or for that matter just about any other website, you've undoubtedly seen the clickbait links for various outrageous lists or stories. I took a picture of this one above, for example. These are called "Cookie mills", because you see all those ads that load on the page? Each single page is setting dozens, in some cases hundreds of cookies into your browser cache, and each time the page loads, the ads may be all different. That small blue triangle that you see in the corner of some of these, referring to a service called "AdSense" is a brand created by Google (GOOG), (GOOGL) that delivers target advertising to you. Well, it's supposed to be targeted anyway, but there are virtually no ads populating this particular page that would be of interest to me. These sites do that because they get paid anytime you visit one of the advertised sites if they were the last people who advertised it to you. That's great for growing revenues for Alphabet, but this stuff slows down your system BIG TIME. Listen to the sound of the fans in your computer next time you click on one. And that junk stays on your hard drive until you clean it out, too. I probably shouldn't complain too much, because I know that some of our partner sites use these links... The question I have is "Why does Google continue to allow this?". Spamming ad links isn't just uninteresting, it's malicious, and is keeping products that I actually might be interested in from reaching me. And if the user gets irritated to the point of installing an ad blocker or popup software, then both parties lose all of that revenue. Maybe they figure it's gone on so long that there's nothing they can do about it. But I would take that into consideration next time you're evaluating Google's earnings. At some point, the users just ignore it. The smarter ones learn not to click on it instead.
