# Media Plan Auto Negation and Auto Harvesting
## Keep your campaigns efficient by automatically removing poor-performing keywords and promoting the ones that drive conversions.
#### Overview
Trellis continuously evaluates every keyword, ASIN, and target to decide what should stay active, what should be paused, and what should be promoted.
Two key systems handle this automatically:
- **Automatic Negation** – removes poor performers.
- **Harvesting Rules** – promotes strong performers into manual control.
You’ll find both in **Advanced Settings → Negation & Harvesting Rules.**
---
#### 🔍 Automatic Keyword & ASIN Negation
Negation prevents wasted ad spend by stopping your ads from showing on search terms or ASINs that don’t convert.
### Options
| Setting | Description |
| --- | --- |
| **Auto Negation (On/Off)** | When enabled, Trellis automatically excludes low-performing or irrelevant search terms. This is done based on the ACOS target and is configurable using the thresholds. |
| **Your Negative Keywords / ASINs** | Add any known poor performers manually — Trellis will respect these across all future optimization cycles. |
💡 *Auto Negation ensures you’re not repeatedly paying for clicks that never lead to a sale.*
### Example
You’re selling “Running Shoes.”
If “trail sneakers” gets 30 clicks and 0 conversions, Trellis automatically adds it as a negative keyword — stopping further spend on it.
---
#### 🌱 Harvesting Rules
Harvesting Rules define when Trellis should **promote successful search terms** from Auto Campaigns into Manual Campaigns.
This is part of Trellis’s “discovery-to-optimization” loop:
1. Auto campaign tests broad queries.
2. High-performing terms are harvested.
3. Trellis creates them as Exact or Phrase targets in manual campaigns.
4. The same term is negated in the Auto Campaign to avoid duplication.
### Configurable Criteria
| Rule | Description |
| --- | --- |
| **Conversions** | Minimum conversions required before harvesting. |
| **Clicks** | Maximum clicks allowed without conversion (set to 0 to rely on conversions only). |
| **Days (Lookback)** | Time window Trellis uses to evaluate performance. |
---
### Example
If your rule says “Harvest after 3 conversions or 25 clicks within 14 days”:
- Trellis automatically promotes any term that meets those thresholds.
- The system then pauses that term in Auto and begins optimizing it manually.
---
💡 **Tip:** Trellis automatically connects Negation and Harvesting — any harvested term is instantly negated in its original Auto Ad Group to prevent overlap (this is part of Trellis’s **Tunneling system**).
