How to Bid Without
Losing Money
This single decision costs most Amazon sellers thousands of rupees every month. Your bid should never be based on what competitors do — it must be based on your own numbers.
There is a precise formula that tells you the exact maximum CPC you can afford — per product, per keyword match type — while staying profitable. This module gives you that formula and shows you how to apply it in your live campaigns.
Same product. Same conversion rate. ₹2 difference in CPC. One scenario loses ₹370 on every ad sale. The other makes a profit. Your bid is not just a number — it is the single variable that determines whether your PPC campaigns make money or silently drain it.
Cost per sale: ₹720
Gross profit: ₹350
Result: ₹370 loss per ad sale
Cost per sale: ₹320
Gross profit: ₹350
Result: ₹30 profit per ad sale
3 Numbers That Define Your Entire Bidding Strategy
Max Affordable CPC does not exist alone. It combines with your conversion rate and gross profit to produce a complete bidding framework for every match type.
| Match Type | Typical CVR | Max CPC | Target Bid | Why |
|---|---|---|---|---|
| Exact Match High Intent | 8% (branded/specific) | ₹350 × 0.08 = ₹28 | ₹28 × 70% = ₹19.60 | Highest intent — highest CVR — can afford higher CPC |
| Phrase Match Medium Intent | 2.5% (category) | ₹350 × 0.025 = ₹8.75 | ₹8.75 × 55% = ₹4.81 | Mixed intent — moderate CVR — conservative bid |
| Broad Match Low Intent | 1.5% (discovery) | ₹350 × 0.015 = ₹5.25 | ₹5.25 × 40% = ₹2.10 | Lowest intent — highest wasted clicks — lowest bid |

What You Learned in Module 3
Your competitor's gross profit and CVR are different from yours. Copying their bid is gambling with your margin. Your Max CPC is the only bid ceiling that matters.
This is your hard ceiling. Calculate it as Gross Profit × CVR%. Bidding above this on any keyword guarantees a loss on every ad sale from that keyword.
A branded exact match keyword at 8% CVR can afford a 5x higher bid than a broad match keyword at 1.5% CVR — even for the exact same product. One ceiling does not fit all.
Exact at 70%, Phrase at 55%, Broad at 40% of Max CPC gives you a structured 3-tier campaign with profit buffers built in — not bids pulled from guesswork.
