See POAS vs revenue-only reporting
Profit Bid connects store costs to ad spend so you bid on margin — not vanity ROAS.
Track POAS automatically from your store — upload profit conversions and scale winners with A/C/X labels.
How CPC fits the funnel
CPC is the entry cost, but profit depends on what happens after the click. If CPC is $0.80 and 4% of clicks convert, your CPA is $20.
Lowering CPC helps only if conversion quality holds. Broad, cheap traffic can crush CVR and raise CPA even as CPC falls.
Levers that move CPC
CPC is set by the auction — you influence it indirectly.
- Higher Quality Score / ad relevance reduces the price to enter.
- Tighter match types and negatives cut wasted expensive clicks.
- Better creatives raise CTR, which can lower effective CPC.
- Bid to profit so expensive-but-valuable clicks stay affordable.
Frequently asked questions

Is a low CPC good?
Only if it comes with strong conversion rate and margin. A low CPC on non-converting traffic just wastes budget more slowly.
How do CPC and CPA relate?
Roughly, CPA = CPC ÷ conversion rate. Halving CPC or doubling CVR both cut CPA in half.
