Custom Guardrails

Beyond the built-in guardrails, you can create custom rules tailored to your specific business requirements.

Creating Custom Rules

Navigate to Settings > Guardrails > Custom Rules. Click 'Add Rule' to define a new guardrail. Each rule consists of a condition, a threshold, and an action (block, warn, or auto-rollback).

Condition Types

Custom guardrails can monitor any metric DEXTRUM tracks: CPA, ROAS, CTR, conversion rate, spend, impression share, quality score, and more. You can also create compound conditions that combine multiple metrics.

Scope Controls

Apply custom guardrails at the account level, campaign level, or ad group level. Campaign-level guardrails override account-level defaults, giving you fine-grained control over how aggressively DEXTRUM optimizes different parts of your account.

Testing Rules

Use the 'Test' button to simulate your guardrail against the last 30 days of optimization history. This shows you how many optimizations would have been blocked, warned, or rolled back by the rule before you activate it.
