The way this will work is that every time you interact with an ad link (accident or not), you will be promoted to confirm your action to open the ad by selecting the "View Site" button. Basically this means that every ad will require two interactions to follow to its destination. Clearly, this should help prevent accidental clicks and lead to better results for Google & advertisers.
I feel this announcement is more for the advertisers than the users. Yes, it will be more convenient for us when using our mobile devices. However, the most important thing it does is it saves advertisers money & helps fine tune advertising results. Asking users for double confirmation to view an ad shows high interest. High quality data from Google for advertisers equals to profit for Google.
When reviewing the ad situation, one must consider developers who profit from accidental clicks. We have all seen the ad-filled applications where ads are cleverly positioned in areas that are susceptible to accidental clicks; it is, for all intents and purposes, a form of art. I have made many developers tens and hundreds of pennies from crafty located ads by accidental clicks. I am sure these developers will not be happy about the prevention measures Google is taking. If profits fall from ad-supported applications, will this sway a developer to release only paid applications? I do not think so but it might trend that way.
As a heavy Android user, I find the positioning of these ads the major reason behind accidental clicks. Having these ads right above frequently used buttons like the home & back soft keys leads to accidental clicks. It is a business, so location is key. It is nice though knowing that Google is looking to fix my "fat finger" problem. What do you think: is Google going about the problem of accidental clicks the right way, or are they posing a solution to a problem that doesn't really exist?
Ads on smartphones are effective, but many of us have at some point clicked on an ad by accident, which ultimately is a bad experience for the user, the publisher, and the advertiser who pays for clicks that may not be valuable. Our team has been analyzing the types of ad formats where accidental clicks are more likely to occur due to ad layout and placement, and are constantly looking at ways that we can combat them. Today, we’re introducing confirmed clicks into all in-app image ad banners on smartphones, which reduces accidental clicks by prompting the user to confirm that they intended to click on the ad.
