In short
An Amazon product launch plan works backward from the orders a day you want. Divide target orders by the conversion rate you expect, which Seller Central calls unit session percentage, to get listing sessions. Take the share of traffic you plan to send from Meta, divide by the share of landing page visitors who go on to Amazon to get the Meta clicks you need, and multiply by cost per click for the budget. For 20 orders a day at a 12% conversion rate, the listing needs 167 sessions a day. New listings with few reviews usually convert lower, so start cautious and update after a few days. Amazon doesn't publish how its search ranking works, so no budget can promise a rank.
What does an Amazon product launch need?
A new listing has no sales history, so Amazon has little reason to show it. Many brands push traffic to it in the first weeks, from Amazon Ads and from outside Amazon, to get early sales and reviews. Meta ads are a common outside source.
The hard part is the budget. Most launch plans start from a spend figure and hope for sales. It's better to work backwards: decide the orders a day you want, then work out the traffic and spend that takes. That turns a guess into a plan you can check after a few days.
How to calculate launch traffic and budget
listing sessions per day = target orders per day ÷ conversion rate sessions from Meta = listing sessions × share from Meta Meta clicks per day = sessions from Meta ÷ share of clicks that reach Amazon Meta budget per day = Meta clicks × cost per click launch budget = daily budget × launch days
- Conversion rate: orders ÷ sessions. Seller Central calls it unit session percentage. A new listing usually converts lower than an established one until it has reviews, so be cautious.
- Share from Meta: how much of the listing's traffic you plan to send from Meta. The rest comes from Amazon search, Amazon Ads and other sources.
- Clicks that reach Amazon: 100% if ads link straight to Amazon. If they go through a landing page first, only some visitors continue.
Worked example
A made-up brand wants 20 orders a day during a 14-day launch. Similar listings convert at 12%. It plans to send 30% of traffic from Meta, through a landing page that passes 40% of visitors on to Amazon, at $1.20 per click. These are the calculator's example values.
- Listing sessions = 20 ÷ 12% = 167 a day.
- Sessions from Meta = 167 × 30% = 50 a day.
- Meta clicks = 50 ÷ 40% = 125 a day.
- Meta budget = 125 × $1.20 = $150 a day, or $2,100 over 14 days.
Linking straight to Amazon instead would cut the budget to $840, but you'd lose the chance to collect emails or explain the product first. That's the trade-off a landing page makes.
What's a good launch budget?
There's no standard figure. A launch budget is good when it fits what a customer is worth to you:
- Meta spend per launch order: here $7.50. Compare it with your margin per order. Spending more than your margin is common in a launch, but you should know by how much.
- Customer value: if launch customers buy again, you can afford more. The max CAC calculator sets a limit from LTV.
- After the launch: the real test is whether sales hold once launch spend stops. Plan for that before you start.
Common mistakes
- Using your best listing's conversion rate. New listings with few reviews usually convert lower. Start cautious and update after a few days.
- Assuming every click arrives. If ads go through a landing page, many visitors stop there. Measure that rate.
- Counting every launch sale as caused by ads. Some launch sales come from Amazon search and would have happened anyway.
- Breaking Amazon's rules. Don't pay for reviews or offer rewards for them. Check Amazon's current policies before using discounts or giveaways in a launch.
How this connects to true incrementality
During a launch, everything is moving at once, so it's hard to tell what Meta added. Amazon Attribution sees only tagged clicks, and Meta sees none of the Amazon sales. After the launch, a holdout test shows what your Meta ads cause on an established listing. Plan it with the holdout test calculator.
Before you launch, check your margin with the break-even ROAS calculator, and make sure stock can keep up with the reorder point calculator. Spillmark measures what Meta ads cause on Amazon once the launch settles. See how lift is calculated.
Frequently asked questions
How much should I spend on an Amazon product launch?
Work backwards from orders a day: divide by conversion rate for sessions, take the share you'll send from ads, and multiply by cost per click. This calculator does it for you.
Does outside traffic help Amazon ranking?
Amazon doesn't publish how ranking works. Many sellers believe sales from any source help. Plan your launch on sales and cost, not a promised rank.
Should Meta ads link to Amazon or a landing page?
Linking straight to Amazon costs less per session. A landing page costs more but lets you explain the product, test messages or collect emails.
What conversion rate should I use for a new product?
Use a similar listing of yours if you have one, and go lower if the new listing has few reviews. Update the number after a few days of real data.
How long should a launch push last?
Many brands plan one to four weeks. Pick a length you can afford at the daily budget, and decide in advance what sales you need to keep going.
