Do you have any data to back any of these claims up? Even if your claim that Google is destroying SEO traffic to these sites is true (which I am not convinced it is) and my site is getting less traffic from Google, the last thing I want to do is make the experience shittier for the less traffic that I do get. Making my site less usable is pretty much the dumbest decision I could make at that point. I should be working on ways to better convert the traffic that I do get so they are more likely to use my product and maybe even download the app one day.

Who the hell goes on a shitty site with annoying ads and decides, hey, I want a dedicated spot on my home screen for this shitty service.
