How it works
Step 1: Collect information from the user message — product, platform, current situation, and goals.
Step 2: Ask all follow-up questions at once in multiple-choice format. Allow abbreviated answers (e.g., "1b 2c 3a").
Step 3: Use the frameworks and methodology below to conduct research and analysis.
Search term efficiency tiers
Four tiers based on conversion efficiency:
- High-converting core keywords: Directly drive sales. Protect and increase bids.
- Low-frequency precise keywords: Some conversions, low clicks. Continue monitoring.
- Weakly relevant occasional converting terms: Low conversion but occasional sales. Evaluate based on CPC and conversion value.
- Completely irrelevant wasteful keywords: Must be added as negative immediately.
Framework: Classify each search term in the search term report into the corresponding tier.
Negative exact match vs negative phrase match logic
- Negative exact match: Blocks only exact match search terms from triggering the ad.
- Negative phrase match: Blocks all search variants containing that term.
- Decision rule: Use negative exact for a single wasteful term. Use negative phrase for a category of irrelevant searches.
- Example:"free" as a negative phrase blocks "free shipping", "buy free", "totally free" — capturing all waste related to "free".
Campaign-level vs ad group-level negative strategy
- Campaign-level negative keywords: Apply to all ad groups under that campaign. Used for terms irrelevant to the entire product line.
- Ad group-level negative keywords: Affect only a specific ad group. Used for fine-tuning across different match types.
- Strategy examples:
- Exact match ad group: Use negative phrase for core keywords already targeted separately
- Broad match ad group: Keep open to continuously discover new search terms
Savings estimation model
Estimated savings = irrelevant search spend - potential lost conversion value
Before implementing each negative keyword, evaluate the net savings effect. Ensure the benefit of the negative keyword action exceeds the potential loss.
Ongoing management framework
- Review frequency: It is recommended to review the search term report weekly.
- Seasonal/temporary negative keywords: Negative keywords added for seasonal promotions should be removed after the promotion ends.
- Keyword harvesting workflow: Continuously "harvest" high-converting terms from broad/automatic campaigns and upgrade them to exact match.
Data sources
- The user exports the search term report from Amazon Seller Central (recommended: at least 14-30 days).
- The report includes: search terms, clicks, spend, conversions, ACoS.
- There is no direct Seller Central API connection.
Limitations
- The completeness and accuracy of the report data directly affect the reliability of the analysis.
- The search term report has a data delay of about 72 hours.
- Amazon hides some low-frequency search terms — not all wasted spend is visible.
- Effects take time to appear — short-term ACoS improvement may not be obvious.
- Search term intent is dynamic — terms that are irrelevant now may become high-converting terms later (seasonality, trends). Regular review is needed.
- It is not possible to connect directly to the Amazon Ads dashboard — it relies on data provided by the user.
Step 4: Provide structured, actionable output with specific recommendations, not vague guidance.
Output format
- Give a summary of findings first
- Include specific data points and benchmarks (if any)
- Provide prioritized action items
