Amazon PPC Optimization: How to Improve Ad Performance with Data

Amazon PPC can feel like a black hole—especially when you’re new and unsure what to track or change.

Without a data-driven plan, it’s easy to overspend on the wrong keywords, miss profitable opportunities, or make the wrong call too soon.

At Flapen, we help new sellers use data to:

• Spot performance trends

• Make informed bid decisions

• Scale what works

• And cut what doesn’t—profitably

This guide explains exactly how to track, interpret, and act on PPC data, so your campaigns become smarter over time—not more expensive.

1. Why Data Matters in Amazon PPC

Amazon gives you access to powerful advertising data. But if you’re not using it consistently, you’re guessing—and that gets expensive.

PPC data shows:

• Which keywords are profitable

• Which ads drive sales vs. clicks

• When and where to increase spend

• How ads impact total brand revenue (TACoS)

Smart sellers don’t spend more—they spend better. And that starts with tracking the right numbers.

2. The 6 Core Metrics You Must Track

If you’re just starting out, focus on these six.

1. ACoS (Advertising Cost of Sales)

Formula: Ad Spend ÷ Ad Sales × 100
Shows how much you’re paying for each dollar of revenue.

• Low ACoS = profitable

• High ACoS = inefficient or early-stage campaign

2. TACoS (Total Advertising Cost of Sales)

Formula: Ad Spend ÷ Total Sales × 100
Tracks ad impact on total business, not just ad sales.

• TACoS falling = organic growth

• TACoS rising = ad-dependence

3. CTR (Click-Through Rate)

Measures how many people click after seeing your ad.

• Low CTR = Listing/title/image needs improvement

• High CTR = Ad is appealing

4. CVR (Conversion Rate)

Shows how many clicks lead to a sale.

• Low CVR = Listing issue (price, reviews, content)

• High CVR = Solid offer and trust signals

5. Impressions & Clicks

• Low impressions = Low bids or poor targeting

• High clicks + no sales = Irrelevant keywords

6. Spend vs. Sales Per Keyword

• Use to identify profitable keywords

• Remove or reduce bids on keywords with high spend and no sales

3. How to Analyze and Act on Your ACoS

ACoS is your most referenced PPC metric—but don’t take it at face value.

Benchmarks:

• Under 20% = Excellent

• 20–35% = Growth-phase range

• 35%+ = High risk, monitor closely

What to do:

• High ACoS + few sales? Pause or reduce bids

• High ACoS + solid sales? Try to lower bids, or keep running short-term (e.g., ranking)

• Low ACoS + sales? Scale that keyword or campaign with higher bids

✅ Always compare ACoS against your net profit margin. A 30% ACoS on a 25% margin = unprofitable.

4. Improve ROI with Smarter Data Use

Here’s how we help sellers improve ROI without spending more:

• Audit underperforming ASINs: Fix listings with low CVR

• Boost Top-of-Search placements: Use placement data to drive better conversions

• Use time-of-day insights: Adjust bids based on conversion windows

• Create winner campaigns: Move top-converting keywords into high-priority Exact Match campaigns

📅 Campaign Optimization Timeline

Before diving into metrics, every seller needs a clear routine for reviewing and improving their campaigns. Here's a simple Gantt-style overview of what to check—and when.

🗂 Legend

✔ = Review or optimize at this frequency
Daily: Prevent overspend or runaway campaigns
Weekly: Maintain control, refine targeting
Biweekly: Deep performance analysis
Monthly: Strategic resets, campaign restructuring

At Flapen, we follow this routine for every seller we support—so ad spend stays efficient and profitable as your brand grows.

5. Segment Campaigns by Performance Tier

Don’t treat all campaigns equally. Group them by results.

Campaign Tiers:

Winner Campaigns

• Low ACoS, high conversions

• Increase bids, expand keywords, protect rank

Test Campaigns

• New terms or new products

• Set moderate bids, monitor daily

• Promote winners, pause losers

Loser Campaigns

• High ACoS, no ROI

• Pause, reduce budget, or revise targeting/listing

Flapen uses this structure for all accounts to simplify decision-making and avoid ad fatigue.

6. Use Search Term Reports to Refine Targeting

Your Search Term Report tells you what people actually typed before clicking.

How to use it:

• Identify high-converting keywords → Transfer to Manual (Exact match)

• Spot irrelevant traffic → Add as Negative Keywords

• Compare match type performance → Decide where to scale

Example:
If "non-toxic baby sippy cup" converts well in Auto, move it to a Manual Exact campaign and raise your bid.

🧠 This process is called keyword harvesting—a core Flapen PPC method.

7. Track Trends Over Time

One week of data isn’t enough.

Monitor:

• ACoS and TACoS over 30, 60, 90 days

• Conversion rate changes post-listing update

• Seasonal shifts in click volume or cost

• Long-term impact of pricing or review improvements

Flapen uses Kapoq to track campaign-level and keyword-level trends across time.
Weekly snapshots are helpful—but real optimization comes from trend analysis.

8. Pro Tips: Mistakes New Sellers Make

Even with great data, bad habits can derail results.

Avoid these:

• Overreacting too fast: Let campaigns run for 7–10 days before pausing

• Only watching ACoS: TACoS shows the big picture

• Skipping listing audits: Ads can’t fix weak product pages

• Ignoring negative keywords: Letting wasteful spend bleed daily

• Failing to harvest winners: Auto campaigns are a goldmine—don’t forget to check

📌 Reminder: Your listing, pricing, and reviews affect ad performance as much as your keywords.

Final Thoughts: PPC Without Data Is Guesswork

Your Amazon ads should grow your brand—not drain your bank account.

To optimize PPC performance, you must:

• Track the right metrics consistently

• Interpret what they mean

• Make decisions weekly—not monthly

• Combine data with execution

• Improve your listing alongside your ads

At Flapen, we help sellers launch with clarity. Our PPC systems are built around weekly data reviews, keyword harvesting, and campaign tiering—so every dollar you spend has a purpose.
