The limiting nature of the post "subject" field hampered my title here. I hope it gets your attention.
I may live under a rock. I know that some of my sites are older and don't have a clever "mobile" version. I'm not running responsive ads either. Ultimately these "choices" are mine. I chose big ads which always have been fine with adsense for mobile.
Everyone may know this. Some may not. I did not. When people come to my site, Google Chrome browser with mobile users promps with a pop up saying "view a mobile friendly version of this website". Sounds nice right? Go ahead and click that. Then you get your website with adsense ads parsed from existence. So you are dishing out an ad free website at that point.
Wonder where the good times have gone? I would have preferred a letter saying this: If you don't go responsive, we're going to block all your adsense ads, provided the visitor clicks on our big banner that is highly intrusive. We are going to serve a non revenue generating version of your website if you don't have a mobile version of some sort.
The way I see it? If I choose to not invest in a mobile option, I'm the fool. Let the customer/visitor leave. Let them decide if my non mobile site sucks. If they don't like it because of how it looks on mobile, let them go away. However, to get in their face about a mobile version of my website that provides me ZERO chance at a click? That's back stabbing in my books.
Did I miss the memo? I live under a rock? Please don't preach to me about 2017 and mobile sites. Duh, I get that. However because I make a choice you can effectively parse out my F'ing site? Come on. That's BS.
