Interest-based advertising will allow advertisers to show ads based on a user’s previous interactions with them, such as visits to advertiser website and also to reach users based on their interests (e.g. “sports enthusiast”).

Currently Interest based advertising is in beta stage and only selected Adsense publishers and Youtube.com displaying this Interest based ads. At this stage it’s difficult to say how this will affect our earnings.

You need to closely track your earnings once your blog/website starts serving Interest based Adsense ads and if you notice any significant decline in your earning then disable Adsense interest based advertising. Here is how you can opt out of interest-based advertising for your site.
