Adsense have just changed their system…
“we’ve just changed our text ads slightly to help reduce accidental clicks. In the past, users could click on both the background and full text of an ad, but now they can click only on the title and URL of a text ad. By allowing users to click only on the ad title and URL, we aim to decrease accidental clicks, better aligning visitor behavior with their intent. Overall, the decrease in accidental clicks will keep users on your website, interacting your content, until they intend to click on an ad.” link
I’m surprised that was important. After all, if you clicked somewhere between the title and url of an ad (ie the actual ad description), you were almost certainly intending to click… which only leaves the “white space” around the ads to generate unintended clicks… that white space is no-longer clickable.
I guess that will decrease some accidental clicks… which is a good thing because even though Adesens publishers will lose a few clicks, the actual advertisers will be willing to pay more per click because their visitors will have definitely wanted to click, which should balance things out for publishers.
Did you spot the deliberate typo? Good.
