We can even maximize your budget and run your ads across multiple ad groups.  Our Campaign Managers evaluate the price and performance of each impression against the metric that matters most to you, and adjusts budgets accordingly to maximize conversions for the budget. During this process we will find efficiencies in the RTB auction process for each campaign.  When we are able to win impressions at a lower than predicted price, we pass that savings on to you in the form of more impressions and conversions for the budget, resulting in the best possible Return on Advertising Spend (ROAS). We will still guarantee a minimum number of impressions and we will optimize to lowest cost per conversion.  We do not guarantee a set number of conversions or leads for a client.
