Is it better to have 3 ad units or 2 ad units and 1 set of text links? Its for my proxies and not sure which is better?
You can place 3 ad units + 3 link units + 3 referrals + 2 search boxes in one page. And I think 3 ad units is good, compared to 2 ad units + 1 link unit as for link units, users have to click two times, only then we are paid.
