How the best sellers use it

A higher break-even ACOS is only powerful if you spend it in the right place

Find the keywords where the market is big but your market share is small. Those are where you can afford to be aggressive, because your LTV-based break-even ACOS lets you pay for clicks your competitors can't.

Bid aggressively where you're small

High search volume, low market share. Your break-even ACOS lets you outbid.

Ad spend lifts organic rank

Winning Top of Search pulls your organic position up on those keywords.

Paid turns into organic

You start selling with no ad cost. Those sales are pure profit.

Reinvest, and it compounds

Profit funds more aggressive bids. Ads → rank → organic → profit → ads.

That loop is the flywheel: every turn costs less and returns more.

Cumulative profit per customer over orders: order 1 is a loss, the curve crosses break-even, then climbs into profit by orders 3, 6 and 12 — Every order returns more than the last, and that profit funds your next aggressive bid.

That is how a competitor "affords" a click you can't. They are not overspending, they are buying market share that compounds into organic profit. My Real Profit shows you which keywords to target (market size versus your share) and the break-even ACOS you can afford on each.

FAQ

Questions, answered

Is it really free?

Yes. Enter your product, get your break-even ACOS, no credit card and no login required.

How is my break-even ACOS calculated?

Break-even ACOS = your margin before ads × how much more a customer is worth over time (their lifetime value multiple). The longer the horizon, the more repeat purchases count, and the higher the ACOS you can afford.

Can a break-even ACOS really be over 100%?

Yes. If customers reorder, their lifetime contribution can exceed the first sale. So you can spend more than the first order is worth to acquire them and still profit across the year. That is exactly how a competitor "affords" a higher CPC than you.

Where do the lifetime-value numbers come from?

They are directional benchmarks by category, not your account data. For your real, account-level lifetime value and break-even targets, connect your account to My Real Profit.

Is my data safe?
