FYI; Content Quality update is already out there for some time, they are just going to roll out on full scale, i have experienced it on my sites.
1: Unique Images
2: Bounce rate
3: Google shows a pop msg when somebody visits your site and clicks back button to come back to google search results; this pop msg states "was this helpful, "yes" "No""
4: Google scrolls to certain part of your article where it detects the information asked during Google search, for example, if topic is "Peter net Worth" when user clicks your website it will automatically scroll to part of content where it is mentioned "Peter net worth is $1 Million" therefore Google detects if the the post topic information is actually mentioned in the content or not.
Fixes
1: Never use google for images, use royalti free images, use instagram, facebook, twitter and take screen shots of images instead download
2: Your site should be black hole, even if your content is AI, you can make user forget to click back button, use sliders, recommended posts, infinite scroll.
3: Always make sure that topic information is mentioned in content, but in second or third paragraph, to decrease bounce rate.
For me AI works as long as i mention the information of topic inside content, and make my website black hole
