Running Amazon PPC campaigns in 2026 is more competitive than ever. Many sellers pour money into ads, yet their campaigns fail to deliver the expected return on investment. The reason is not always traffic; it’s poor campaign optimisation.
Without a structured PPC audit, sellers often waste thousands on irrelevant clicks, high ACoS, and low-converting keywords. This blog provides a complete Amazon PPC audit checklist highlighting 15 critical mistakes that can silently drain your ad budget and reduce profitability. Follow these actionable strategies to optimise campaigns, increase conversions, and scale sales efficiently.
1. Poor Campaign Structure
A messy campaign setup leads to inefficient budget allocation. Ensure campaigns are organised by:
- Product category
- Match type (Broad, Phrase, Exact)
- Campaign objectives
A clear structure helps track performance and identify profitable keywords.
2. Ignoring Search Term Reports
Search term reports are vital. Analyse them to:
- Identify irrelevant keywords
- Discover high-performing terms
- Reduce wasted spend
Regularly update negative keywords to prevent non-converting clicks.
3. Not Using Negative Keywords
Without negative keywords, ads can trigger for unrelated searches. Add negatives for terms like:
- cheap
- free
- replacement
- low quality
This reduces wasted spend and improves CTR and conversion.
4. Low CTR on Ads
Low click-through rates indicate your ad creatives or product titles/images are not engaging. Audit:
- Product images
- Titles
- Pricing
- Ratings
Improved CTR signals relevancy to Amazon’s algorithm.
5. Poor Conversion Rate
Clicks without purchases reduce campaign efficiency. Check if:
- Landing pages are optimised.
- Bullet points highlight benefits
- A+ content enhances trust
- Reviews and ratings support buyer confidence
Optimised conversion ensures ad spend translates into revenue.
6. Incorrect Match Types
Using only broad match can waste budget. Structure campaigns to include:
- Broad Match (discover new terms)
- Phrase Match (refine targeting)
- Exact Match (scale winning keywords)
This provides precise targeting and better ROI.
7. Improper Budget Allocation
Some campaigns may overspend without producing conversions. Audit:
- Daily budget vs performance
- Campaigns with high ACoS
- Underperforming ad groups
Shift budgets toward profitable campaigns.
8. Placement Optimization
Amazon allows ads in:
- Top of search
- Product pages
- Rest of search
Analyse which placements yield the highest conversions and adjust bids accordingly.
9. Bid Strategy Review
Regularly check:
- Dynamic bids vs fixed bids
- Placement bid adjustments
- CPC trends
Avoid overspending on low-performing keywords.
10. Product Targeting Campaigns
Leverage product targeting campaigns for:
- Competitor listings
- Complementary products
- Related categories
Optimise for sales, not just visibility.
11. Track ACoS and TACoS
ACoS shows ad efficiency; TACoS reflects total profitability. Regular monitoring allows informed decisions about scaling campaigns.
12. Review Ad Scheduling
Dayparting helps allocate budget efficiently. Pause campaigns during low-converting hours.
13. Optimize Keywords Continuously
Monitor high-intent keywords, eliminate non-performing ones, and expand profitable terms. This ensures campaigns remain effective.
14. Analyze Competitor Ads
Competitor analysis provides insight on:
- Keywords
- Creative strategies
- Promotions
- Ad placements
This can reveal gaps in your PPC strategy.
15. Scale Gradually and Test
Avoid aggressive scaling. Increase budget in steps and monitor performance to ensure profitability is maintained.

- Reduced wasted spend
