Lesson 2: Use the 320×100 Ad Unit Above the Fold (ATF)

Welcome to lesson #2 of the FREE Mobile Ad Optimization Course. We sure hope you’re on momentum to get your mobile site and ads ready for income generation.

Today, we will discuss Google’s very popular large mobile banner: the 320 x 100 ad unit. This ad unit appears automatically in your list of sizes if you manage your inventory via DFP.

How the 320 x 100 can Increase your eCPM

320×100 ad unit typically yields higher CTRs versus the usual 320×50. One of the reasons for this is its great text fill (large mobile banner), producing more click-throughs:

When you use the 320 x 100 ad unit, it can compete against the 320 x 50 ad, enabling you to increase your fill-rate because of the added pressure. This leads to higher eCPMs, thus more ad revenue for you.

If you have a responsive site, or if you use Google’s responsive ad units, you don’t need to worry about the 320 x 100 not fitting into the mobile screen. With Google’s responsive units, it will automatically shrink to the ideal mobile screen size and thus will lead to a better user experience.

Research shows that the most valuable ad position is right above the fold.

Tips on using the 320 x 100 ad unit

  • Look for your most engaging pages on mobile via Google Analytics. These will be the pages where you will integrate the ad unit.
  • Reclaim the space above the fold on these pages (or throughout your site) by hiding the URL bar
  • Implement the 320 x 100 ad unit on ad slots above the fold. You can do this via DFP.
  • Test your page/s on mobile and see how the 320×100 ad placement flow with your content. Ideally, there should be a smooth flow between ads and content (not too distracting) to enhance user experience.

Lesson 2- Action Items

  1. Sign up to DFP and implement your 320×100 ad unit above the fold to let it compete with the 320×50.
  2. Make sure there is 150 pixel distance between your ads and hyperlinked elements to avoid accidental clicks

That concludes our lesson for today. Don’t forget to come back next Thursday for another edition of the FREE Mobile Ad Optimization course. Next week, we will tackle the 320×250 mobile ad unit and its most optimal placement. Until next time!

    Can the 320X100 ad unit be set as a sticky unit?

    • MonetizeMore

      It can but it’s quite invasive, we would recommend 320×50 or 300×50.
