Google has changed the way in which AdSense advertisements can be clicked. Previously users could click the entire box that housed the advertisement but now, only the title and URL are clickable.
According to AdSense Blog the move was implemented to,
“reduce the incidents of invalid and accidental clicks on ads and to encourage site visitors to stay on the site, interact with the site content and if they deemed it necessary, click on the ads. The new clickable format aligns with the text ad formats that is being implemented on Google. The new format would also benefit Google advertisers by making them pay for ad clicks that were intentional and would contribute to the success of their ad campaigns.”
The change is good news for advertisers, as now they will have a clearer picture of how well their advertising campaigns are going, with the potential decrease of no value clicks. However, publishers will most likely experience a drop in revenue, as it becomes harder to get clicks. Overall, it is a good move that should increase the accuracy of the AdSense service.
