Amazon PPC launch strategy: cap the loss, then let conversion rate end the launch.

An Amazon PPC launch strategy is a planned loss with a cap and an end date: decide what you will lose before the first click, bid hard only on the few keywords that describe the product, and let conversion rate, not ACoS, tell you when the launch is over. A new product has no reviews and no sales history, so it converts worse than it will later. Every launch click costs more than it earns at first. That is fine if you chose how much, and it is how most launches bleed for months when you did not.

Most launch guides give you a daily budget, $10, $30 or $100 a day, and tell you a high ACoS is normal. Neither says how big the loss can get, or when to stop. This post works both out from your own margin, then covers the part a new listing needs most: its first reviews.

Why a new product loses money on PPC at first

Take an example product that sells for $30 with $12 of margin per order before advertising, which is 40% of the price. Its break-even ACoS is 40%: spend more than that share of the sale on ads and the order loses money. If the term is new, start with what ACoS is and how to calculate it.

With no reviews, say the listing converts 5% of clicks. That is an example input; once it has reviews, say it reaches 10%. The most a click is worth is price × margin before ads × conversion rate. At launch that is $30 × 40% × 5%, or $0.60. At 10% it is $1.20.

Now bid $1.00 to get seen on the main keywords. At 5%, one order takes 20 clicks, so it costs $20 of ads. ACoS is 67% and each order loses $8. At 10%, one order takes 10 clicks, costs $10, ACoS is 33% and each order makes $2. Same bid, same keyword, opposite result. The only thing that changed is conversion rate.

So there is one number that ends the launch: the conversion rate at which your bid breaks even. It is the bid divided by margin per order, here $1.00 ÷ $12, or 8.3%. Below it, every order is an investment. Above it, the product pays for its own ads.

The rule: set the launch loss before you launch, and end the launch when conversion rate passes bid ÷ margin per order. Judge it on conversion rate, not on ACoS.

Amazon PPC launch strategy: size the loss, not the daily budget

Pick a launch length and a daily budget, then work out the worst case: conversion never rises above the launch level. In the example, $30 a day for 60 days is $1,800 of spend. At $1.00 a click that is 30 clicks a day. At 5% conversion that is 1.5 orders a day, 90 orders in total and $1,080 of margin. The worst-case loss is $720.

Run the same product at the $100 a day some guides suggest and the worst case is $6,000 of spend, 300 orders, $3,600 of margin and a $2,400 loss. More spend does not make the listing convert better. It only buys more orders at the launch price. If you would not hand over $2,400 to learn whether the product works, do not set a budget that can.

Amazon's own guide for new advertisers says just $10 a day can get clicks and sales, so a small cap is not too small to learn from. Write the cap down. When it is spent, the launch is over whatever the dashboard says.

The campaigns: one exact, one auto, nothing else yet

Put the launch bid where the product is most likely to convert: an exact-match campaign on the 5 to 15 keywords your title describes. These are the searches where a shopper with no reviews to read still sees what they typed. If you are unsure which match type does what, see Amazon PPC match types.

Next to it, run an automatic campaign at the click value of the launch, $0.60 in the example. Amazon's guide recommends automatic targeting for new advertisers to find relevant keywords and products, and at a lower bid it can do that without eating the cap. Our comparison of auto and manual campaigns covers how the two work together.

Leave broad campaigns, competitor ASIN targeting and extra ad types for after the launch. They spread the same cap across more searches, and a product with no reviews shown next to a well-reviewed rival rarely wins the side-by-side comparison.

Then cut keywords that prove they will not sell. At 5% conversion you expect one order every 20 clicks. A keyword with 40 clicks and no order, twice the expected count, has cost $40 for nothing: lower its bid or add it as a negative. Search terms from the auto campaign that do sell move into the exact campaign, as in search term harvesting.

The first reviews decide how fast conversion rises

Amazon's new-advertiser guide tells sellers to advertise products that have five or more customer reviews with a rating of 3.5 stars or higher, alongside four or more images and at least three bullet points. A launch starts with none of the reviews. That is why conversion sits low, and why the fastest way to end the loss is to get the first reviews, not to raise the bid.

Amazon Vine is the established route. Per Amazon's Vine page, a product qualifies with an FBA listing, fewer than 30 reviews and, if it has a brand, a brand enrolled in Brand Registry. You offer up to 30 units. Enrolment is free for up to 2 units per parent product, $75 for 3 to 10 units and $200 for 11 to 30. You are not charged until your first Vine review is published, and not at all if none arrives within 90 days. New sellers who enrol a brand in Brand Registry get a $200 Vine credit.

Review Requests is new. Amazon announced it on 29 September 2026: a paid campaign that invites recent buyers to leave a star rating or a written review while they shop. It is for products with fewer than 1,000 total ratings and reviews, pauses itself at 1,000, uses the same bid and budget controls as other Amazon Ads campaigns, and opens in beta in the US in late October 2026. Amazon reports three times as many ratings and reviews per week in its closed beta, from 3 to 21 June 2026, compared with the same products before the test. PPC Land notes that figure has no control group, and Amazon has not described what the ad is billed on.

Treat it as a second, small test with its own cap. What it costs per review is the number to watch, and you will only know it from your own campaign. Outside the US, Review Requests is not available yet.

Launching in Q4 2026

A launch started now runs through the peak. Black Friday is Friday 27 November 2026 and Cyber Monday is Monday 30 November 2026, as set out in our Q4 2026 Black Friday and Cyber Monday plan. Amazon's holiday advertising guide suggests raising daily budgets by 20 to 30 percent around both days. The listings you bid against can do the same, and they have reviews.

So keep the launch bid at its launch level through that week. If the click you need to stay visible rises from $1.00 to $1.30, an example figure, each order at 5% conversion costs $26 and loses $14. If peak shoppers convert better, the same $1.00 bid profits on its own; you do not need to chase. A gift product that only sells in the holiday season may be worth the higher price. An everyday product can wait and start the clock after Cyber Monday. Either way, check stock first: a launch that sells out in the peak weeks may not be restocked before they end. Our post on inventory-aware bidding covers what a stockout costs your ads.

What to do before you launch

1. Work out margin per order before ads and the break-even ACoS it gives you.
2. Set the launch bid and the cap. Multiply daily budget by launch days, then subtract the margin from the orders the launch conversion rate would bring. That is your worst case. Write it down with the end date.
3. Calculate the exit conversion rate: bid ÷ margin per order. That is the line the launch has to cross.
4. Build two campaigns: exact match on the 5 to 15 keywords that describe the product, and an automatic campaign bid at the launch click value.
5. Start on reviews on day one with Vine, and in the US consider a small, capped Review Requests campaign.
6. Check every week: harvest terms that sell, cut keywords with twice the expected clicks and no order, and stop when the cap is spent or conversion crosses the line.

Common questions

How much should I spend on PPC for a new product launch?

Start from the loss you can accept, not from a daily number. In our example a $30 daily budget for 60 days caps the loss at $720 even if conversion never improves. Amazon’s own guide for new advertisers says just $10 a day can get clicks and sales.

What ACoS is normal when launching a product on Amazon?

Higher than break-even, because a listing with no reviews converts less. In the example, ACoS is 67% at launch against a 40% break-even. What matters is that it falls as conversion rate rises, and that the loss stays inside the cap you set.

Should I use auto or manual campaigns for a product launch?

Both. An exact-match manual campaign on the 5 to 15 keywords that describe the product carries the launch bid. An automatic campaign at a lower bid finds the searches you did not think of.

When does an Amazon product launch end?

When conversion rate clears the level where your bid breaks even, when the loss cap is spent, or on the end date you set, whichever comes first. In the example that level is 8.3% at a $1.00 bid.

The one-line version

Decide the loss before the launch, bid on what the product is, get the first reviews fast, and stop when conversion rate says the product can pay for its own clicks.
