Yesterday I went to Allow and block Ads in the CP and unchecked the three advanced settings. The traffic was the same this morning, however I got a third fewer clicks and a lot less $$$.
Has anyone messed with those settings:
1) Ads based on user interest categories are allowed to show. Visitation information from my sites may be used to help create interest categories.
Third Party Ads Preference
2) Advertisers are allowed to use their audience information to deliver more relevant ads to my site.
Social Ads Preference
3) The use of +1 related features and social annotations in ads is allowed.
