Most Amazon PPCaccounts we audit are bleeding money. Auto campaigns running indefinitely with no negative keyword strategy. Manual campaigns with bid auto-pilots that drive ACOS up. Sponsored Brand campaigns competing with Sponsored Product campaigns for the same keywords. The fundamentals are the problem, not the platform.
- This guide reflects 2026 best practices, updated based on actual client engagements.
- The frameworks below have been tested across multiple verticals and team sizes.
- Specific numbers, ranges, and benchmarks come from real operator data, not generic industry averages.
- The advice assumes you have basic infrastructure in place; if you don't, the foundational sections cover that.

Campaign structure that scales
Three-tier campaign structure for each product or product family. Tier 1: Auto campaigns for discovery, runs at low bids to find new keywords Amazon algorithmically matches you to. Tier 2: Manual broad/phrase match campaigns for proven keywords with controlled budgets. Tier 3: Manual exact match campaigns for top performers with aggressive bids. This separation lets you scale spend on winners without polluting discovery campaigns.
Sponsored Brand campaigns get their own structure tier, they target category awareness keywords and drive brand searches, not direct conversions. Bid them differently than Sponsored Products.
Bid strategy
Use dynamic bidding "down only" for discovery campaigns. Use "up and down" for proven manual exact campaigns where you want Amazon to bid more aggressively on high-converting placements. Avoid "down only" on proven campaigns, you cap your scaling.
Bid optimization frequency: weekly review of top 20% of keywords by spend, monthly review of long tail. Avoid daily bid changes, Amazon's algorithm needs 7-14 days to stabilize on bid changes.
Top of search modifier: bid up 25-50% for proven exact-match campaigns where placement matters. Skip for discovery campaigns. (See Amazon Seller Centralfor the official documentation.)
Negative keyword strategy
Most accounts have either no negatives or messy negatives. Both bleed money. Build negative keyword lists from search term reports, any term that has spent more than 2x your target ACOS without converting becomes a negative. Add to negative campaign-level lists, not just ad group level.
Add negative product targets too, if certain ASINs are getting your ads but not converting, add them as negative ASINs. This is a feature most sellers miss.
Budgeting
Allocate 70% of PPC budget to proven exact-match campaigns, 20% to broad/phrase research campaigns, 10% to auto discovery. Adjust monthly based on what is working.
Budget pacing matters. If your daily budget caps out before the day ends, Amazon stops showing your ads, you miss the highest-converting evening shopping hours. Set daily budgets at 110-120% of expected daily spend to avoid caps.
Sponsored Brand strategy
Sponsored Brand campaigns target category awareness, not direct conversion. Target competitor brand keywords (defensive), category keywords (offensive), and your own brand keywords (protective).
Use Sponsored Brand Video format for top of search, it drives 2-3x higher CTRthan image-only Sponsored Brand. Production cost is real but ROI is significant.
Sponsored Display strategy
Sponsored Display drives off-Amazon retargetingand on-Amazon competitor targeting. Use it for: defensive ASIN targeting (your own listings to capture browsers), competitor ASIN targeting (steal their traffic), and remarketing audiences (people who viewed your products but did not buy).
Reporting and optimization cadence
Daily: budget pacing check (5 minutes). Weekly: search term report review and negative keyword updates (45 minutes). Monthly: full performance review by product, campaign type, and keyword (3 hours). Quarterly: strategy review with seasonality and product roadmap input.
Most accounts under-optimize because they review too infrequently. Most accounts over-optimize because they make daily bid changes. Find the cadence that produces consistent monthly improvement without thrashing.
Benchmarks
Healthy ACOS varies by category and product margin. As a rule: aim for ACOS at 50-70% of your contribution margin. If your CM is 30%, target ACOS of 15-20%. If your CM is 50%, target ACOS of 25-30%.
Healthy TACoS (Total Advertising Cost of Sales, ad spend ÷ total revenue from that product, including organic): 8-15% for established products, 15-25% for new launches in their first 90 days.
