Margin-aware Amazon seller decision support
CEILR combines controlled competitor keyword discovery, seller-supplied evidence, product economics and bounded PPC planning—so each evaluated term keeps its source, financial ceiling and next action.
Visibility & Profit
CEILR does not display generic CPC ceilings, sample rankings or invented keyword results.
One focused Amazon seller platform
CEILR is built around a single job: turning discovered and supplied keyword evidence into a decision your product margin can actually support.
Discovery & Index Checker
Use seed keywords and selected competitor ASINs to collect spend-capped, source-labelled marketplace observations. CEILR does not claim complete reverse-ASIN coverage.
Profit & PPC Engine
Calculate contribution profit, maximum ad spend, break-even ACoS, target ACoS, profit-safe CPC and required conversion rate.
Waste & Harvest
Review seller-owned performance evidence against loss limits, stop rules and contribution economics before deciding what to harvest, monitor or avoid.
Campaign Lab
Define match type, starting bid, budget, maximum test loss, negatives, stop rule and review date. Plans remain seller-controlled.
Action & Proof
Record what was applied, preserve the supporting evidence and compare a later non-overlapping performance period without claiming causation.
From discovery and supplied evidence to controlled action
Each stage adds information the next stage needs. The output is traceable from the final recommendation back to the evidence and economics that produced it.
Profile
Enter marketplace, selling price, landed cost, Amazon fees, tax treatment and target contribution profit.
Discover or supply evidence
Use seed terms, selected competitor ASINs, seller-owned inputs and permitted third-party exports. Results are sampled provider observations, not a complete competitor keyword universe.
Check
Use Discovery and Index Checker for seed terms, supplied keywords and selected ASINs, with organic, sponsored and demand observations kept source-labelled.
Evaluate
Steal, Defend, Test, Listing Only, Monitor, Avoid or Do nothing yet—with the reason and source trail visible.
Control & prove
Set limits before launch, then review later seller evidence against the recorded decision.
The CEILR difference
CEILR focuses on the decision layer between seller research and execution. Controlled discovery results remain sampled, source-labelled observations and are not presented as complete market coverage.
Request beta accessSeller reports, licensed observations, imported third-party figures and derived calculations are not presented as the same kind of truth.
A keyword is not promoted simply because demand or visibility looks attractive.
The output includes a decision class and, when appropriate, a controlled test plan—not only a score or export.
Later results can be reviewed against the original evidence without falsely claiming the change caused the outcome.
Data truth and product trust
CEILR is designed to make assumptions visible. It does not turn estimates into facts or imply access to a competitor's private account data.
Product economics, keywords, Amazon reports and other inputs supplied by the workspace user.
Timestamped marketplace visibility returned through an enabled licensed provider.
Third-party demand or suggested-CPC figures only when supplied or enabled, labelled rather than presented as Amazon-published facts.
Contribution, ACoS limits, profit-safe CPC, required conversion and decision classes calculated by CEILR.
Product safeguards
Controlled private beta
Access is approved case by case while paid-beta checkout, legal terms and support operations are finalised. A request does not create a paid subscription, guarantee acceptance or enable public signup.
Frequently asked questions
CEILR runs controlled competitor keyword discovery, evaluates seller-supplied keywords and reports, combines them with enabled licensed marketplace observations and product economics, then produces source-labelled affordability limits, decision classes and controlled test rules.

Seller-owned reports and inputs, enabled licensed marketplace observations, imported third-party figures and CEILR-derived calculations. Important metrics retain a visible source label.
