Well placed ads are vital to both earnings and user satisfaction. Too many ads and your users will flee your site while your brands will see low performance and pay less. Ads in the wrong location will result in low viewability resulting in very low eCPMs since no Brand wants to buy an ad that isn’t seen.
Balancing earnings with user happiness is easy when the ads are well placed in the page flow and/or seen as tools for the user.
