For those who need to run DFP or some other ad network that requires fixed ad space (728x90 Leaderboards), here's my solution w/ the help of others (@
Brogan).
- Get your main template tweaked to perfection before adding any advertisements.
- When you are completely satisfied, create a child template (Mobile)
- On the main template, uncheck 'responsive' in Style Properties. In general > page width controller > Miscellaneous > width: 1030px; margin: auto; (that number can vary, but if you want to run leaderboards above breadcrumb, this number seems to work best with flowing over content.
- Setup all of your ads on this template.
- On your child template, set up your responsive ads. Check the box 'prevent template modifications'. This isn't necessary, but will help if you make a change to any of your desktop ads. I used the ad code provided by Google for responsive adsense.
- Install Mobile Style Selector and the add on for tablets (can't seem to find the link). Set this accordingly.
I've done other tweaks to avoid too many ads on 'thin' pages. IMHO, the limitation of ad networks makes this the best solution.
Hope this helps.
