One of the most common and costly mistakes Amazon sellers make with PPC is this:
đźš« They guess their bids when adding new keywords.
Whether you’re launching a brand-new product or expanding an existing campaign, setting the wrong bid from the start can do serious damage—burning your budget, missing impressions, or distorting your campaign data.
But here’s the good news:
👉 There’s a smarter, more strategic way to set Amazon PPC bids for new keywords—and in this post, we’re going to walk you through it step-by-step.
We’ll cover:
âś… Why setting the right bid from day one matters
âś… The dangers of guessing or using default bids
âś… How to research and determine competitive bid ranges
âś… Smart bidding strategies for short-term data and long-term profit
âś… Optimization tips for refining bids once performance data rolls in
Let’s jump in.
🎯 Why Your Initial PPC Bid Matters More Than You Think
Amazon’s advertising algorithm is built around auction-based bidding. That means:
- You set a max bid
- Amazon compares it to other sellers’ bids
- Your ad’s visibility depends on how your bid stacks up plus your ad relevancy and performance history
Here’s the kicker:
👉 When you add a new keyword to a campaign, Amazon has no performance data yet.
So if your bid is too low, Amazon may not give it enough impressions to even test.
If your bid is too high, you may win placements that cost you more than the keyword is worth.
Getting the bid “just right” gives you a chance to earn impressions, collect data, and scale efficiently.
🚨 What Happens When You Guess (or Use Default Bids)
Let’s say you just added 50 new keywords to a campaign.
Option A: You copy and paste the same bid for every one.
Option B: You use Amazon’s “suggested bid” without question.
Option C: You randomly plug in what you think is competitive.
The problem?
- Some keywords are low competition and your high bid will overspend
- Others are high competition and your low bid won’t even show
- You miss out on valuable A/B testing insights
- Your campaign becomes inefficient or unscalable
The result:
🔥 You burn ad dollars without gaining actionable performance data.
đź“Š How to Research Smart Bid Ranges for New Keywords
Before setting any bid, you need to do some groundwork. Here’s how:
1. Use Amazon’s Suggested Bids—But With Caution
In Campaign Manager, when you add keywords, Amazon provides a suggested bid and a range.
This is based on historical competition and recent trends, but it’s not perfect.
What to look for:
- Suggested bid = Starting point
- Low end of the range = Conservative test
- High end of the range = Aggressive test
đź“Ś Tip: For brand new keywords, avoid going straight to the high end unless it’s a high-priority or highly relevant keyword.
2. Use Tools Like Helium 10, Jungle Scout, or SellerApp
Keyword research tools can show:
- Average CPCs
- Search volume
- Historical trends
- Seasonality
- Organic competition
đź“Ś Tip: Keywords with high search volume but low CPCs are prime opportunities for affordable traffic and fast data.
3. Analyze Your Own Historical Campaign Data
If you’re launching keywords related to existing products or campaigns:
- Look at CPCs and conversion rates for similar keywords
- Use those as a baseline for your new bids
- Aim for comparable performance
đź“Ś Tip: Your best-performing keywords can offer clues about what your target ACoS should be, too.
🧠Smart Bidding Strategies for New Keywords
Once you’ve done your homework, it’s time to launch your new keywords with smart bids. Here are 3 proven approaches:
1. Tiered Bid Testing Strategy (Most Recommended)
Set up multiple ad groups with the same keyword but different bid levels.
- Ad Group A: Low bid (e.g., $0.50)
- Ad Group B: Medium bid (e.g., $0.75)
- Ad Group C: High bid (e.g., $1.00)
Watch which bid level gains impressions, clicks, and conversions. Pause or scale based on results.
đź“Ś Why it works:
You can test where your keyword is most profitable without guessing. And you get clear insight into where the bid is too low, just right, or too expensive.
2. Keyword Prioritization Strategy
Not all keywords are created equal. Assign different bid strategies based on the value of the keyword.
High-value keywords:
- Highly relevant to your product
- High buyer intent
- Use aggressive bids to win impressions and collect early data
Medium-value keywords:
- Related terms or secondary use cases
- Use moderate bids
Low-priority or exploratory keywords:
- Lower intent or broader keywords
- Use conservative bids to test cost-effectiveness
đź“Ś Why it works:
This approach lets you manage budget risk while still discovering profitable terms.
3. Break Keywords into Match Types with Adjusted Bids
When adding a new keyword, break it into:
- Exact Match — Set highest bid (most relevant)
- Phrase Match — Set moderate bid
- Broad Match — Set lowest bid (discovery mode)
This helps you:
- Control relevancy
- Discover long-tail variations
- Keep testing costs manageable
đź“Ś Why it works:
You maximize keyword coverage without blowing your budget on low-converting broad terms.
đź’ˇ Tips to Optimize Bids After Initial Testing
Your first bid isn’t your final bid. Once data starts rolling in, adjust based on performance.
Watch These Key Metrics:
- CTR (Click-Through Rate): If low, consider changing title/image or reducing bid
- CVR (Conversion Rate): If high, raise bids to scale
- CPC (Cost Per Click): Compare to profit margin to see if it’s sustainable
- ACOS (Advertising Cost of Sale): Track against your target ACoS
đź“Ś Optimization Window:
Give new keywords 7–14 days to collect enough data before making major changes (unless performance is drastically bad).
Use Negative Keywords to Clean Up
Don’t just bid up winners—eliminate losers.
Add search terms with:
- 10+ clicks and no sales
- Irrelevant queries
- Poor conversion history
as Negative Exact or Negative Phrase to prevent further waste.
Scale Slowly and Monitor TACOS
As keywords begin to perform:
- Gradually increase bids
- Track how it affects both paid and organic sales
- Watch your TACOS to ensure your ad efforts are driving total revenue, not just ad clicks
🚀 Real-World Example: How Smart Bidding Saves You $$$
Let’s say you’re launching a premium yoga mat.
You’re targeting the keyword “eco-friendly yoga mat”, and Amazon’s suggested bid is $1.20.
Instead of guessing, you:
- Create 3 ad groups: $0.80, $1.00, $1.20
- Monitor for 10 days
- See that $1.00 gets 90% of the impressions and conversions
- Pause the $0.80 and $1.20 groups
- Scale up $1.00 group with a slightly higher daily budget
Result?
You now know the most profitable bid zone for this keyword—and you scaled without overspending.

✍️ Final Thoughts: Smart Bidding = Smarter Scaling
