See POAS vs revenue-only reporting
Profit Bid connects store costs to ad spend so you bid on margin — not vanity ROAS.
CPA falls as conversion rate rises
- CPA at $1 CPC
At a fixed $1 CPC, each point of conversion rate sharply reduces cost per acquisition.
Track POAS automatically from your store — upload profit conversions and scale winners with A/C/X labels.
Why CVR is the biggest lever
Because CPA ≈ CPC ÷ CVR, improving conversion rate compounds: a jump from 2% to 3% cuts CPA by a third at the same CPC.
Unlike the ad auction, CVR is largely under your control — landing pages, offers, reviews, and checkout friction all move it.
What drives conversion rate
Common, high-impact CVR drivers for ecommerce:
- Page speed and mobile experience.
- Clear pricing, shipping, and returns information.
- Social proof: reviews, ratings, trust badges.
- Frictionless checkout and payment options.

What is a good ecommerce conversion rate?
Many stores fall between 1.5% and 3.5%, but it varies by category, price point, and traffic source. Track your own trend and segment it.
Does CVR affect my ad profitability?
Directly. Higher CVR lowers CPA, which raises POAS at the same order margin — often the cheapest way to make ads profitable.
