What if i selected: Do not show ads that are based on user-interest categories. would be better? or what is better to protect our niches? we want more clicks, Higher Cpm! If we stayed with do not show ads that are based on user-interest categories. we need to change our Privacy policy too or in this case we don't need to change anything?
u can only opt out of showing ads based on interest categories. but ads may still be shown using the stats of ur users previous interaction with the publishers site. u still need to change ur privacy policy because of the above reason.
