I'm new to AdSense. I want to place an ad on most of the pages of my website, which are articles (mostly text).
For mobile devices, I'd like the ad to appear below the headline and below some of the article text, but at least partially visible above the bottom of the screen ("above the fold"). Is there a way to do this within AdSense? If so, how can it be done? If not, is there a relatively simple way to do it programmatically? My site is Ruby on Rails.
