The Google ad income dropped across all the devices that were in use on Wednesday.
The company said that this was due to lower search volume on Google’s mobile devices, but the drop was also driven by the reduction in the number of ads displayed.
The drop was driven by a fall in the Google ad spend of $2.2 billion on mobile devices.
Google said that the ad revenue fell across the home depot and desktop as well.
Google has been increasing its advertising spend to offset this trend, and it’s working to make the ads more relevant to consumers.
The company also said that it would be reducing the number and the types of ads that are displayed on Google search.
On Wednesday, Google said that its advertising revenue was down by $1.6 billion in the fourth quarter of 2015.
It added that it has reduced its ad spend by $6.5 billion to $17.5 trillion in the past four quarters.
Google said it expects the decline in advertising revenue to continue through to the end of 2016.
