Formulas and relationships

Metric Formula Example
CPM (Cost / Impressions) × 1000 500 PLN / 50 000 × 1000 = 10 PLN
CPC Cost / Clicks 500 PLN / 1000 = 0.50 PLN
CPA Cost / Conversions 500 PLN / 10 = 50 PLN
CTR (Clicks / Views) × 100% 1000 / 50 000 × 100 = 2%
CR (Conversions / Clicks) × 100% 10 / 1000 × 100 = 1%
CPC from CPM CPM / (CTR × 10) 10 / (2 × 10) = 0.50 PLN
CPA from CPC CPC / (CR / 100) 0.50 / 0.01 = 50 PLN

How to lower ad costs?

Better targeting

The more precisely you reach your target audience, the higher CTR and CR, and lower CPA.

Better creatives

Test different images, copy and CTAs. Higher CTR = lower CPC at the same CPM.

Landing page optimization

A faster, better-converting page = higher CR = lower CPA.

Ad schedule

Turn off ads during hours/days with low conversion.

Negative keywords

Exclude keywords that don't convert (Search/Shopping).

Remarketing

Cheaper traffic, higher CR - reach people who already know you.
