Google announced today that it will roll out +1 in its ads that are served as part of adsense for content.
The idea is that people will see an add and click the +1 if they like it. My initial question is wont they just click on the ad? doesnt that show relevancy in the degree of CLICKTHROUGH. Higher clicktrough rates suggest relevancy, though the author has seen ads based more and more on my search history rather than the page content ! So this is why then perhaps it needs another metric to measure..

I value your thoughts on your own  interaction style –
Do you click on the +1’s
Do you click on the facebook ‘like’
Do you click on the tweet this share buttons ?
