How can we add ads (eg Google adsense) to SharePoint hosted app ?
I haven't used Google adsense. However, I have used ads from Developer Media previously and am currently using ads from SharePoint ads in my blog. Normally, they give you an HTML ad code and the instructions for pasting the code in the pages. The ad code of developer media used to be a
div tag with some publisher specific details where as SharePoint ads uses a
script tag. So, if you want to show ads in a SharePoint hosted app, you can get the HTML code from adsense and add it to the app pages.
