Google is looking to raise the value of mobile ads by eliminating accidental clicks. With recent studies showing that as many as 50% of clicks on mobile ads are accidental, clickthrough rates can be raised by these mistaken taps. This results in higher costs for advertisers. Companies end up paying for clickthroughs created by consumers not really interested in buying what the company is selling.
So Google is making some changes to block accidental clicks. One way is to block clicks that take place near the border of an ad’s image.
