Use the first month to establish product readiness, trustworthy reporting and a repeatable decision process. A calendar is a planning aid, not a guarantee of enough data or a particular ACoS. A low-traffic account may need longer before judging performance.

Before launch: make the product ready

Check price, delivery promise, saleable stock, listing accuracy and Featured Offer eligibility. Sponsored Products requires eligible offers; a bid cannot fix an unavailable product. Amazon new-advertiser guide.

Calculate contribution after variable costs and choose an acceptable test-loss limit. Confirm how the account's daily budget settings operate and monitor actual spend rather than assuming an exact daily charge.

For reviews, use only permitted methods. Check current Amazon Vine eligibility if relevant; do not plan around a historical review program or promise a positive review outcome.

Week 1: bounded discovery

Start with a manageable product group so the offer economics are understandable. Automatic targeting can surface relevant queries and products; manual targeting is also reasonable when you already have specific evidence. Neither is mandatory for every account.

Set bids from a conservative economic estimate and assign a limited discovery budget. Monitor eligibility, rejected ads and unexpected spend. Do not judge yesterday's missing conversions as final.

Hypothetical example: a £30 order leaves £9 contribution before advertising. At 5% expected CVR, break-even expected CPC is £0.45. A £0.60 CPC would require CVR above £0.60 / £9 = 6.67% to cover advertising on this simplified basis. A universal 3% CVR threshold cannot establish break-even.

Week 2: inspect queries and evidence

Export the advertising search term report with dates and export time. Separate product mismatches from relevant terms with uncertain performance. Review mature traffic before moving a term into a dedicated manual target. Ten clicks do not make a result statistically reliable by themselves.

When creating a manual target, record its source and intended role. Add a routing negative only after deciding that the discovery campaign should no longer serve that query and confirming the destination is active. See the auto-to-manual workflow.

Week 3: narrow avoidable spend

Review negative exact and phrase candidates at the narrowest valid scope. Preserve useful longer queries when considering phrase exclusions. Recalculate bids if price, fees or stock changed. Make one bounded intervention and record the old value, reason and review condition.

Amazon conversion reporting depends on the metric and advertiser type. Select a mature observation period rather than relying on the calendar week alone. Amazon conversion guidance.

Week 4: decide whether to expand

Consider another format only when the objective, eligibility, creative and measurement are ready. Sponsored Brands is not a compulsory fourth-week milestone. For professional sellers, Brand Registry is part of its eligibility; other advertiser types have their own routes. Sponsored Brands eligibility.

Illustrative £1,000 monthly planning envelope: £600 established relevant traffic, £250 discovery and £150 uncommitted reserve. That is 100% of the envelope. Allocate by actual opportunity; an account without established traffic should not pretend to have “winners” simply to fit the template. Monitor cumulative spend against the envelope.

End-of-month review

Check whether the account has eligible products, comparable reports, recorded changes and an owner for the next review. Measure spend, orders, sales and contribution after ads. Mark incomplete or sparse results honestly. There is no promised 25–35% ACoS destination and no fixed waste percentage to remove.

What if ACoS is still high?

Check economics, retail readiness, traffic relevance and reporting maturity. Continue only within your approved learning limit. Use the ACoS spike diagnosis before a broad shutdown or expansion.
