You’ve already nailed the PPC basics. Your Sponsored Products are running, you’re harvesting keywords, and your listings are dialed in. But here's the problem: your ACoS won’t budge, or worse—it’s climbing. Every tweak seems to mess with your traffic, and sales start to dip.
If you’re stuck in the PPC tug-of-war between ad efficiency and growth, you're not alone. According to the PPC experts at SELLERPRO, there’s a smarter way. This post breaks down five intermediate tactics we use every day to help Amazon brands lower ACoS without killing their momentum.
Why It Matters
A rising ACoS isn't just an ad problem. It’s a profit leak. With aggressive competitors and ever-shifting Amazon algorithms, you can’t just “set and forget” your campaigns.
SELLERPRO’s approach defends your ad budget, sharpens targeting, and keeps sales velocity strong. The goal? Higher profit and long-term rank without sacrificing traffic.
TL;DR – Quick Wins from SELLERPRO
Adjust placement bids based on CVR and performance.
Mine search term reports to kill costly, non-converting terms.
Separate branded vs competitor campaigns.
Snipe weak competitors with Sponsored Product targeting.
Track TACoS to catch hidden profit leaks.
1. Optimize Placements for Strategic Bidding
SELLERPRO recommends: Reviewing your placement report weekly and adjusting bids accordingly.
What It Is: Placement optimization lets you adjust bids for top of search, rest of search, and product pages.
How to Do It:
Go to the Placements tab in Campaign Manager.
Increase bids where you see strong CVR and profitable ACoS.
Why It Works: You focus spend where it drives results, not where it looks flashy.
Pro Tip: Brands managed by SELLERPRO experts who review placement data weekly consistently outperform the broader Amazon seller average in ACoS improvements.
2. Categorize Campaigns for Enhanced Targeting
SELLERPRO recommends: Splitting campaigns by product line or margin group to improve targeting.
What It Is: Segmentation by product or category gives you cleaner data and tighter control.
How to Do It:
Create separate campaigns per brand, product type, or margin tier.
Optimize based on specific performance.
Why It Works: You avoid overlapping goals in one campaign and create more actionable data.
Pro Tip: Start with top-performers or high-margin SKUs—then build out.
3. Exploit Product Targeting for Competitor Sniping
SELLERPRO recommends: Using Sponsored Products with ASIN targeting to go after weaker listings.
What It Is: Product targeting places your ad on specific competitor product pages.
How to Do It:
Target ASINs with poor reviews, high price, or weak visuals.
Leverage your better offer to convert buyers.
Why It Works: You win buyers mid-funnel, directly on competitor pages.
Pro Tip: Don’t just undercut on price—leverage your brand visuals, reviews, or value prop.
4. Split Branded vs Competitor Keywords
SELLERPRO recommends: Creating separate campaigns for branded and competitor keyword sets.
What It Is: Running them together muddies the data and confuses targeting.
How to Do It:
Branded campaigns = high CVR, low ACoS, low bids.
Competitor campaigns = lower CVR, higher ACoS, more budget + testing.
Why It Works: You can scale more confidently and evaluate ROI cleanly.
Pro Tip: Use distinct ad creatives and copy for each to align with intent.
5. Master the TACoS for Comprehensive Profit Insight
SELLERPRO recommends: Tracking TACoS (Total Advertising Cost of Sale) alongside ACoS for the full picture.
What It Is: TACoS = ad spend / total revenue (paid + organic).
How to Do It:
Monitor TACoS weekly.
Look for spikes or trends even if ACoS looks stable.
Why It Works: TACoS reveals if ads are supporting or cannibalizing organic growth.
Pro Tip: A rising TACoS with flat sales means something’s broken—fix early.
