What Does Advertising Cost of Sales (ACoS) Mean

To put it simply, ACoS is the percentage of your revenue that went toward ads. In 2026, many Indian sellers will see an average ACoS of around 30%. If you sell a product for ₹1,000 and spend ₹300 on ads for that sale, your ACoS is 30%.

Tracking ACoS is the only way to know if your Amazon PPC optimization strategies are actually working or just wasting your hard-earned money.

ROAS stands for Return on Ad Spend, and it is the opposite of ACoS. It tells you how many Rupees you earn for every ₹1 spent on advertising.

In 2026, aiming for a higher ROAS is the best way to how to increase ROAS on Amazon Ads and scale your brand.

What is a Good ACoS on Amazon

A good ACoS depends on your product price. Usually, an ACoS between 15% and 25% is considered very healthy for established products. However, if you are launching a brand-new item, you might have a higher ACoS temporarily just to get your first few customers and reviews.

How to Increase ROAS on Amazon Ads

To get a better return, you need to show your ads only to people who are truly ready to buy your product right now. Here are the top 6 Amazon PPC optimization strategies to increase your ROAS on Amazon Ads:

1. Use Negative Keywords Regularly

One of the fastest ways to reduce ACoS on Amazon Ads is to use negative keywords. If people search for free or cheap products and click your premium product without buying, you lose money. By marking these words as negative, your ad won't show up for them anymore, saving you thousands of Rupees.

2. Focus on Top-Performing Keywords

Don't spread your budget too thin across 100 different keywords. Find the 5 or 10 words that actually bring in sales and put more money behind them. This simple Amazon PPC bidding strategy ensures your budget is spent where it actually results in profit.

3. Optimize Product Listings First

Before spending on ads, make sure your product title and images are perfect. If your listing is confusing, people will click your ad (costing you money) but leave without buying. Gonukkad offers expert Amazon listing optimization services to make sure your page is ready to convert visitors into customers.

4. Adjust Bids Based on Performance

In 2026, you shouldn't pay the same price for a click at midnight as you do at 8 PM. Most Indian shoppers buy in the evening. Lowering your bids during the night and increasing them during peak hours is a great way to lower the advertising cost of sales for Amazon.

5. Separate Your Campaigns

Keep your Automatic and Manual campaigns separate. Use Automatic campaigns to discover new keywords, then move the successful ones into a Manual campaign where you have more control. It is a key part of Amazon Ads campaign optimization that prevents overspending.

6. Monitor Your Competitors

Watch what other sellers are charging. If your competitor drops their price significantly, your ad clicks might not turn into sales because customers will go for the cheaper option. Staying aware of the market helps you adjust your Amazon PPC bidding strategy in real-time to stay competitive.

Conclusion

Managing Amazon Ads in 2026 requires a balance of patience and data. By focusing on the right keywords and constantly checking your numbers, you can easily reduce ACoS on Amazon Ads and make your business more profitable.
