Media buying

    Purchasing the advertising space and time the plan calls for - negotiating rates, placing orders, or trading programmatically - and stewarding the spend as it runs. The execution half of media, graded on the price and quality of the attention it secures.

    Where it's used

    Used in agency negotiations and in-house programmatic and social buying. Good for getting better prices and placements for the same plan.

    How to calculate it

    Impressions bought = Budget ÷ CPM × 1,000

    Worked example

    Illustrative numbers

    You plan a $100,000 buy. The first quote is a $12 CPM, and you negotiate it down to $10.

    At $12 CPM

    $100,000 ÷ $12 × 1,000 = 8,333,333

    At $10 CPM

    $100,000 ÷ $10 × 1,000 = 10,000,000

    What it tells you

    That is about 1.7 million more impressions for the same money, as long as the cheaper placements get seen as often as the old ones.
