After wasting ~$2,000 on misaligned ad budgets during my first Prime Day (yikes), I spent 4 years testing budget scaling and cutting strategies across 2 different Amazon categories. This framework is what I use now to avoid leaving sales on the table and stop throwing money at low-ROI ad spend. Let’s get into it.

  • Cut budgets gradually, and stop immediately if daily orders drop more than 15% week-over-week

  • All adjustments must tie back to your core goal for that listing phase (rank growth, profit maximization, etc.)

  • For mid-tier sellers, cut pre-peak budgets by 30% 1 week out, then fully release (or increase) spend on peak day to avoid wasted spend on low-conversion pre-peak traffic

When to Scale Your Ad Budget

Scaling spend works best when you’re in a phase where extra ad dollars directly translate to more orders, faster rank growth, or higher long-term profit. These are the 4 only windows I scale spend:

  1. Initial New ASIN Launch Phase

Amazon provides temporary organic traffic boosts for new listings during their first 30-90 days on the site. Scaling your budget here lets you collect large volumes of click, conversion, and keyword data quickly, so you can optimize your Listing and ad campaigns faster to hit consistent daily order volume as soon as possible.

  1. Phase of Consistent Ad-Driven Order Growth

If every time you increase spend, your order volume rises proportionally, keep testing higher budgets to find your maximum ROI ceiling. For example:

  • $50/day ad spend = 20 orders

  • $80/day ad spend = 30 orders

  • $100/day ad spend = 30 orders

Your current maximum efficient budget here is $80/day—any spend beyond that won’t drive additional orders, so you cap it at $80 until your listing’s organic rank or conversion rate improves. Retest the ceiling every 2 weeks as your listing matures.

Note: Adjust your bid levels alongside budget changes to align with the average Cost-Per-Click (CPC) for your category and Amazon site.

  1. Relaunch After a Stockout

Listings that go out of stock lose significant organic rank and traffic momentum, so your top goal during relaunch is to reactivate Amazon’s algorithm signals as fast as possible.

For example, if you have a $1,500 total relaunch ad budget:

  • Allocating $100/day for the first week post-restock, then $38/day for the following 3 weeks, drives 2x faster rank recovery than a flat $50/day spend across 4 weeks. Frontloading spend gives the algorithm a clear signal that your product is still high-demand.
  1. High-Traffic Peak Events (Prime Day, Black Friday, Cyber Monday, Category-Specific Sales)

There are two core reasons to scale spend on peak days:

  • Conversion rates are 2-5x higher than average for most categories, so extra spend directly drives far more orders than usual

  • If your competitors scale spend and capture more market share on peak days, their rank will rise above yours in the days following the event, even if you had higher rank pre-peak

Note: Scaling during peaks varies heavily by category. Test small increases first, especially if you’re a small to mid-sized seller prioritizing profit over top-line revenue.

When to Cut Your Ad Budget

Cutting spend is not about slashing budgets randomly—it’s about eliminating low-ROI spend without hurting your order volume or organic rank. Cut spend only in these 3 scenarios:

  1. Stable Order Volume But Disproportionately High Ad Spend

This is most common in the late launch phase: for example, your target is 50 orders/day, but you’re stuck at 20 orders/day even after increasing spend from $60/day to $100/day, and this trend lasts for 7+ days.

When cutting spend here:

  • First pause low-conversion, high-spend Negative Keywords before adjusting overall campaign budgets

  • Reduce budgets gradually (5-10% per day, not 50% all at once)

  • Stop cutting immediately if your daily order volume drops more than 15% compared to the prior 7-day average—go back to the previous day’s budget and optimize your targeting before trying again

  • This phase requires patience: it can take 2-4 weeks to find the right balance between spend and order volume.

  1. Mature Listings With No Further Ad-Driven Growth

Once your listing hits a stable rank and order volume that doesn’t rise when you increase ad spend (usually with ad spend sitting at ~10% of total revenue), you can slowly cut spend to boost profit.

The goal here is to reduce spend without lowering order volume. Every 1% you cut from your ad spend-to-revenue ratio is an extra 1% in net profit, so even small adjustments add up fast. Cut 2-3% of your budget every 3-4 days, and pause if order volume dips.

  1. Pre-Peak Event Periods With Below-Average Conversion Rates

In the 7 days leading up to major peak events, most shoppers hold off on purchases to wait for sale discounts, so conversion rates drop 20-40% for most categories.

For mid-tier sellers running above-average Advertising Cost of Sale (ACOS):

  • Cut your daily ad budget by 30% 7 days before the peak event to avoid wasting spend on low-conversion window shoppers

  • Release the full saved budget (or increase by 20-50%) on the peak event day to capture high-intent sale traffic

Note: Top-tier sellers typically maintain or even increase pre-peak spend to hold their rank leading into the event. This strategy is only recommended if profit is your top priority, not top-line market share.

Core Rule: All Adjustments Tie Back to Your Phase Goal

The biggest mistake I see sellers make is adjusting budgets without a clear goal for their listing’s current phase:

  • Launch / post-stockout relaunch phase: Your goal is fast data collection and rank growth, so prioritize order volume over short-term profit

  • Mature stable phase: Your goal is profit maximization, so any budget adjustment that lowers total profit (even if it cuts spend) is a bad move

  • Peak event phase: Your goal is either rank retention/market share growth or maximum profit—align your budget changes to whichever you’ve prioritized

If you’re in the profit maximization phase and your order volume drops after a budget cut, you’ve gone too far: prioritize restoring order volume first, then re-test smaller spend cuts.

Quick Reality Check

There are no universal “hacks” or one-time fixes for ad budget optimization. Every listing, category, and seller has different goals, so you’ll need to test, iterate, and adjust this framework to fit your needs. The only consistent rule is to track your 7-day average order volume and ACOS closely with every change, so you can catch negative impacts early.

I’m currently testing this pre-peak budget strategy for the upcoming Prime Day in the home goods category, and so far we’re seeing a 12% reduction in wasted pre-peak spend compared to last year.
