Amazon Pay-Per-Click (PPC) advertising has become a vital tool for sellers looking to increase visibility, drive traffic, and ultimately generate sales. However, the question of the minimum ad spend to start an Amazon PPC campaign is frequently asked, especially by beginners hoping to make the most of their limited marketing budgets. Understanding the costs involved and planning accordingly can make a major difference in the success of a campaign.
Understanding Amazon PPC Basics
Before diving into the budget aspect, it’s important to understand how Amazon PPC works. Sellers bid on keywords, and their products appear in Amazon’s search results or product pages when shoppers search for those keywords. Unlike traditional advertising, you only pay when someone clicks on your ad.
Amazon offers three main types of PPC ads:
- Sponsored Products: Ads that promote individual product listings in search results and product detail pages.
- Sponsored Brands: Banner ads that showcase your brand and multiple products.
- Sponsored Display: Ads that appear both on and off Amazon to retarget customers.
Each ad type has its own pricing dynamic, but all follow a cost-per-click (CPC) model.
Is There a Minimum Ad Spend?
The good news is that Amazon does not enforce a hard minimum ad spend. However, there are certain limitations and practical considerations sellers need to be aware of:
- Daily Budget: Sellers must set a daily budget, and the minimum for most campaigns is $1 per day.
- Bid Amount: The minimum keyword bid can be as low as $0.02 to $0.05, depending on category and competition.
In theory, a seller can start a PPC campaign on Amazon with as little as $30 per month. However, realistic performance requires a higher budget to generate enough data, impressions, and eventually conversions.

Recommended Starting Budget
While it’s technically possible to start small, experts recommend beginning with a monthly PPC budget of at least $300 to $500. This allows for:
- Testing multiple campaigns and keywords
- Gathering meaningful performance data
- Adjusting bids and strategies based on real outcomes
Keep in mind, the more competitive your product category is, the higher your CPC will be — sometimes reaching $1 to $4 per click. This makes small budgets challenging in high-competition niches.
Maximizing a Small PPC Budget
For those who can’t afford a larger budget initially, there are strategies that can help stretch ad dollars and still gain traction:
- Use Automatic Campaigns: Start with Amazon’s automatic targeting to learn what keywords are converting.
- Target Long-Tail Keywords: These are less competitive and cheaper, offering better ROI for small budgets.
- Set Negative Keywords: Prevent your ads from showing in irrelevant searches to save money.
- Monitor and Optimize Regularly: Review performance daily or weekly and pause non-performing keywords or campaigns.

When to Increase Ad Spend
Once you’ve validated keyword performance and started seeing conversions, increasing your PPC budget makes sense. A common rule of thumb is to reinvest a percentage of your revenue back into ads. Many sellers aim for spending around 10–15% of their gross product revenue on PPC.
Scaling your ad spend in conjunction with ROAS (Return on Ad Spend) performance ensures that you’re not just increasing costs but also building sustainable growth.
Final Thoughts
While there’s no strict minimum ad spend to start a PPC campaign on Amazon, beginners should plan to commit at least $5 to $10 per day for effective testing and optimization. Starting with a small but focused campaign, learning from the data, and scaling wisely can help new sellers succeed on Amazon’s competitive advertising platform.
