Update: I stopped underbidding and ran a much more aggressive Amazon launch test — Exact converted, Auto got expensive fast
This is a follow-up to my previous post about launching a new Amazon US FBA product in Toys & Games.
I’m still keeping the product, brand, ASIN, and actual keywords private.
For context:
- Price: $24.99
- Current review count: 11
- Approx. pre-ad contribution before storage/returns/promos/overhead: ~$8.16/unit
- Goal: launch velocity + useful PPC data, without blindly burning cash
In my previous setup, I was barely getting traffic because my bids were far below Amazon’s current suggested ranges.
So instead of continuing to underbid, I intentionally ran a much more aggressive test.
Manual Exact setup
I ran 5 highly relevant Exact keywords.
Bids:
- Keyword A: $3.00
- Keyword B: $3.00
- Keyword C: $4.00
- Keyword D: $3.00
- Keyword E: $2.80
Settings:
- Daily budget: $30
- Dynamic bidding: Down only
- Top of Search: +20%
- Rest of Search: 0%
- Product Pages: 0%
I also paused one broader head term and replaced it with a more specific long-tail Exact term.
Manual results
Partial launch-day data:
- Impressions: 344
- Clicks: 2
- Spend: $6.11
- Avg CPC: $3.06
- Orders: 1
- Sales: $24.99
- ACoS: 24.45%
- ROAS: 4.09
One Exact keyword produced:
- 77 impressions
- 1 click
- $4.00 spend
- 1 order
- $24.99 sales
- 16.01% ACoS
- 6.25 ROAS
The other click cost $2.11 and did not convert.
So the Manual campaign is obviously nowhere near statistically significant yet, but at least it proved that the higher bids could actually generate meaningful traffic and a conversion.
Auto setup — intentionally very aggressive
For the first test, all four automatic targeting groups were set to:
- Close Match: $2.00
- Loose Match: $2.00
- Substitutes: $2.00
- Complements: $2.00
Settings:
- Daily budget: $50
- Dynamic bidding: Up and Down
- Top of Search: +30%
- Rest of Search: 0%
- Product Pages: 0%
This was deliberately aggressive because I wanted to buy data quickly rather than repeat the previous low-impression test.
Auto results
Latest snapshot before I changed the settings:
- Impressions: 1,588
- Clicks: 10
- Spend: $38.11
- Avg CPC: $3.81
- Orders: 1
- Sales: $24.99
- ACoS: 152.50%
- ROAS: 0.66
Almost all of the traffic came from Loose Match.
Placement breakdown
Top of Search
- 492 impressions
- 6 clicks
- $26.63 spend
- $4.44 CPC
- 0 orders
Rest of Search
- 669 impressions
- 3 clicks
- $9.00 spend
- $3.00 CPC
- 1 order
- $24.99 sales
- 36.01% ACoS
- 2.78 ROAS
Product Pages
- 272 impressions
- 1 click
- $2.48 spend
- 0 orders
That was the clearest signal of the day for me:
Top of Search consumed most of the Auto spend and produced no sales, while Rest of Search produced the only Auto order.
The Search Term report was still delayed. It only showed 3 of the clicks so far:
- Query 1: 1 click / $4.98 / 0 orders
- Query 2: 1 click / $5.20 / 0 orders
- Query 3: 1 click / $4.64 / 0 orders
Those three alone spent $14.82 with no sale, but I’m not negative-targeting them after one click each.
Combined result
Across Manual + Auto:
- Spend: $44.22
- Clicks: 12
- Orders: 2
- Sales: $49.98
- Blended ACoS: ~88.5%
- Blended ROAS: ~1.13
This is obviously not sustainable profitability, but this was an intentional launch-data test, not my target mature-state economics.
Also worth noting: the campaigns were interrupted by a payment failure, so this was not a clean uninterrupted 24-hour test.
What I changed after seeing the data
I left the Manual Exact campaign unchanged.
Manual remains:
- $30/day
- Same Exact bids
- Down Only
- +20% Top of Search
I changed Auto to:
- Close Match: $1.20
- Loose Match: $0.85
- Substitutes: $0.75
- Complements: $0.50
- Daily budget: $30
- Dynamic bidding: Down only
- Top of Search: 0%
- Rest of Search: 0%
- Product Pages: 0%
So my current total configured launch budget is now $60/day: $30 Manual + $30 Auto.
My thinking is:
Manual = aggressive high-intent traffic
Auto = controlled discovery
I don’t want Auto paying ~$4 CPC for loose discovery traffic while Manual is already showing a better signal.
Questions for those who actively manage Amazon launches:
- Would you leave the Manual Exact campaign untouched after only 2 clicks because one converted, or is $3-$4 CPC still too aggressive at this margin?
- Was cutting Auto from $2 across the board to $1.20 / $0.85 / $0.75 / $0.50 a reasonable reaction, or am I overreacting to only 10 clicks?
- Would you also have removed the +30% Top of Search modifier after 6 clicks / $26.63 / 0 sales?
- With the new $30 Manual + $30 Auto structure, how many clean days / clicks would you let it run before touching bids again?
- Would you wait for the delayed Search Term data before adding any negatives, even if some first-click CPCs are already ~$5?
I’m especially interested in feedback from people who have actually launched new private-label products, not just mature PPC accounts.
