Starting February 15, 2018, Google Chrome has begun some ad-filtering. They won’t be blocking all ads but the ones that do not pass the standards set by the Coalition for Better Ads. They are targeting the most intrusive ads like the full page ads that block you from seeing the page content and flashing animated ads. In other words, they aren’t out to remove all ads but just the most annoying ones. They are also looking at the number of ads on a page.
You can also install ad blockers in your browser or visit YourAdChoices to optout of ads from the Digital Advertising Alliance.
