Google is testing a cool new mobile AdSense format. Instead of just showing the same AdSense formats as desktops and laptops, mobile smartphones now have a cool new “arrow button” next to the ads. Take a look at the screenshot to the right and below.

User adoption of mobile smartphones is growing exponentially. Some studies suggest that smartphone Internet adoption will surpass desktops and laptops as early as 2014-2015. As such, companies like Google are embracing the technology. Users are spending more and more time browsing the Internet on their smartphones, due to larger and better screens (and also faster processors). It only makes natural sense that Google tests and optimizes AdSense formats for mobile browsers. Via my landing page testing, I know that arrows can really improve conversion rates. I bet the new AdSense formats are going to have better CTRs than their predecessors for sure. It shall be interesting to see if Google keeps the new format around.

Are you advertising on mobile yet? If not, I definitely recommend starting out with some mobile AdWords campaigns. From there, you can also expand by going after Google’s display network (the ads featured in this post) and also other search engines (such as Yahoo!/Bing).
