Controlled automation with visible logic.
Terra PPC automation is built from rules you can read: conditions, an action, guardrails and a mode. Every evaluation checks scope and limits before anything happens, and important outcomes are designed to be recorded.
Three modes, chosen per rule
Manual
Delegation level 1 of 3Preview → Direct control
Review
Delegation level 2 of 3Evaluate → Recommend → Approve
Auto
Delegation level 3 of 3Evaluate → Guardrails → Apply → Audit
The bars show how much each mode delegates. The checks before every sequence are the same in all three.
How the rule engine works.
Evaluation order is fixed. A rule cannot reach its action until the entity is in scope, the guardrails pass and conflicts are resolved — in every mode.
Data window
Authorized metrics for a configured lookback period, inside the selected scope.
Conditions
Thresholds such as ACoS above target and clicks at or above a minimum.
Scope check
The entity must belong to the selected organization, account, profile and marketplace.
Guardrails
Floors, ceilings, change caps, cooldowns and action limits.
Conflict check
Other rules proposing changes to the same entity in the same cycle.
Mode
Manual previews, Review queues a recommendation, Auto applies eligible actions.
Audit record
Inputs, decision and result are recorded.
A rule you can read line by line.
Profit Guard lowers bids on keywords that spend above target once there is enough data to trust the signal.
Rule logic
IF ACoS > Target ACoS
AND Clicks ≥ Minimum Threshold
THEN Create Bid Adjustment

The same rule in each mode
Manual
Shows the proposed $1.08 bid as a preview. No change is made; the user decides.
Review
Creates a recommendation. The bid changes only after a permitted user approves it.
Auto
Applies $1.08 because it passes every guardrail, then writes the audit record.
Manual, Review, Auto.
Choose per rule how much to delegate. Manual keeps every change in your hands, Review puts a person between the recommendation and the change, and Auto applies eligible actions inside guardrails.
Manual: Automation can be inspected or simulated, but it does not apply operational changes. Users make changes themselves.
Review: Rules evaluate conditions and Terra PPC creates recommendations. Nothing executes until a user approves it.
Auto: Eligible actions apply automatically inside the configured scope, permissions and guardrails, and each one is written to the audit log.
Automation mode does not bypass account authorization, scope, guardrails, permissions or audit logging.
Every mode follows the same trunk: data, rule evaluation, scope check and guardrails. Manual ends in a preview with no automatic change. Review creates a recommendation that must be approved before it is applied and recorded in the audit log. Auto applies eligible actions within guardrails and records them in the audit log.
Manual
Direct control. Users review data and make operational choices themselves.
Review
Recommendation-first. Rules evaluate eligible data and create recommendations for human approval.
Auto
Guardrailed execution. Eligible rule actions may execute automatically within configured authorization, scope, safeguards and policy constraints.
Conditions
What a rule looks at before it proposes anything.
- Efficiency thresholds
- ACoS, ROAS, CPC or conversion rate compared with configured targets.
- Minimum data
- Clicks, impressions, orders or spend required before a rule may act.
- Lookback windows
- The period a rule evaluates, such as the last 7, 14 or 30 days.
- Profitability comparisons
- Break-even or target ACoS, where product economics are configured.
- Entity filters
- Campaign type, match type, profile, marketplace or customer-defined groups.
- Business context, where authorized
- Selected seller-business signals, such as inventory context, that change what a rule should do.
Actions
What a rule is designed to do when its conditions are met.
- Bids
- Increase, decrease or set bids for keywords and targets.
- Budgets
- Adjust campaign budgets within configured limits.
- Status
- Pause or enable entities that meet conditions.
- Negative targeting
- Propose or add negative keywords and targets.
- Search-term promotion
- Propose converting search terms as new keywords.
- Placements
- Adjust placement bid modifiers based on placement performance.
- Schedules
- Time-based (dayparting) concepts for supported actions.
Available actions depend on approved Amazon Ads API access, the ad product and marketplace, and the modules enabled for each customer.
Safeguards
Terra PPC is designed to support guardrails that every automated or recommended change must pass, whatever the mode.
An action that would cross a guardrail is not executed. It is blocked, reduced to the limit where configured, or routed to review.

Conflict resolution
When two rules disagree about the same keyword, Terra PPC is designed to resolve it deterministically — the same inputs always produce the same outcome.
- 1Detect. Two proposals target the same entity in the same cycle.
- 2Apply priority. The configured rule priority decides which proposal is considered first.
- 3Prefer the conservative outcome. When priorities tie, the change that reduces spend or risk is preferred.
- 4Route to review. Conflicts that cannot be resolved by policy become a recommendation.
- 5Record. Both proposals and the resolution are written to the audit history.

Audit trail
Every important action should be explainable. Terra PPC is designed to record what changed, why, the source, the mode, the before and after values, the applicable rule, the timestamp and — where appropriate — how to reverse it.
- Automation, user and AI-assisted changes use the same record format
- Approvals and rejections in Review mode are recorded with the reviewer
- Previous values are kept so eligible changes can be reversed
IllustrativeIllustrative workflow example.
AI and MCP-assisted workflows do not bypass automation modes, permissions or safeguards.
A request from an AI client is evaluated like any other: it is authenticated, authorized and scoped, and any change it proposes follows the rule's mode and guardrails.
