I have about 50% of my website's traffic on mobile devices (iOS and Android.) The RPM for mobile is much worse than RPM for desktop.

Is there any way I should do to increase the RPM?

Data here:

PV     | Click   |   CTR   |   CPC  |   RPM 

652,183  16,283   2.50%     $0.22    $5.43

High-end mobile devices 
657,782  6,504    0.99%     $0.09    $0.93

46,873   657      1.40%     $0.15    $2.08

I have the same issue too, except my RPM for mobile averages to $0 – Mike Apr 25 '15 at 19:01
only 25%? mine is more than 50% less than desktop. Site is very well mobile optimized.. I guess mine problem is in very long pages.. but wanted to figure what one can do in such issue. – user54055 Jul 11 '15 at 7:40

When your RPM is so low for mobile devices, it is a sign that your site does not display well on mobile devices. To improve the RPM for mobile devices:

  • Show a page that is only as wide as the mobile device.
  • Use the viewport meta tag to prevent your site from showing zoomed out with tiny text: <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1">
  • Use ad units sizes that have lots of inventory yet still fit on mobile screens: 320x50 and 300x250
  • Like desktop, figure out where on the page to place your advertisements so that they get noticed. I tend to use a 320x50 near the top of the page (but not the very top) and a 200x250 unit interspersed with the content.

This does require some development work to make mobile devices work well with your site. I do this with user agent sniffing and rewriting the page server side. AdSense recently released responsive ad units so that you could change your ad sizes using responsive design as well.

I have all these things on my sites, but my rpm is still far lower than desktop (less than 25%) – boomhauer Nov 27 '14 at 4:14
