Because of poorly designed or malicious ads, people are installing ad blockers at an increasing rate and making it harder and harder for free content to exist.

This announcement will have a devastating effect on publishers, marketers and bloggers that use ads as one of the ways of generating revenues for the sites. Google can also help you in their Ad Experience Report Help Forum.
