Budget momentum
A retail brand invests $12,000 to launch a summer promo across social and video placements.
Truth is:Every bid you win raises total cost, so staying on plan depends on controlling CPM and reach growth.
Example:At week one, CPM holds at $6.00 while you gather 2 million impressions, keeping spend aligned with the $12K budget.
Tips:If CPM creeps up, careful the most expensive placements to avoid blowing through the campaign cap.
CPM tells the rate story
Mid-flight, CPM drifts from $6.00 to $8.50 as competition heats up on premium inventory.
Truth is:Higher CPM means each impression eats more budget, shrinking the impressions you can afford.
Example:At $8.50 CPM, you would only buy about 1.4 million impressions with the same $12,000 budget-400K fewer exposures.
Tips:Lean on CPM trends to negotiate, expand targeting, or shift to placements with healthier rates.
Impressions show audience reach
After creative tweaks and tighter targeting, CPM settles back to $6.50 and impressions climb again.
Truth is:Improving CPM frees budget to deliver more ad views without raising spend.
Example:A $12,000 budget at a $6.50 CPM restores reach to roughly 1.85 million impressions while maintaining quality views.
Tips:Compare impressions and CPM together to confirm whether optimizations are driving efficient scale.
