Tired of dumping hundreds of dollars into Amazon Pay-Per-Click (PPC) ads, only to see your ad hit the top of search results with zero conversions? I’ve spent three years testing keyword placement strategies across 17 different Amazon categories, and I’m breaking down exactly what works, what doesn’t, and when you should even bother with it in the first place.

Plenty of sellers have strong opinions on keyword placement. Some write it off entirely as a waste of budget, others try it once with zero prep and end up frustrated when it doesn’t deliver results. The reality is that most strategies don’t fail because the tactic itself is bad, they fail because sellers skip the foundational work first, or use it for products that don’t have market fit.

Last year, I tested the exact same placement strategy on two Listings in the kitchen category. The first was a replacement air fryer filter, with a CVR of 18% which is 3 points above the category average and 42 reviews with a 4.7 star rating. I shifted 60% of my ad budget to Top of Search (TOS) positions for my top 5 KeyWords, and my ACOS dropped from 28% to 19% in two weeks, with overall sales up 32%. The second Listing was a silicone baking mat, with a CVR of 8% which is 6 points below the category average and only 7 reviews with a 3.8 star rating. I spent $1,200 targeting the same TOS positions for 2 weeks, and my ACOS hit 57%, with only 12 sales and zero profit. The only difference between the two tests? The quality of the product and the Listing itself.

First, let’s clarify the three core sponsored ad placement types on Amazon. Top of Search (TOS) refers to the first few spots above organic results on the first page of search results. Rest of Search (ROS) covers all other ad spots across all search results pages, below the TOS section. Product Detail Page (PDP) includes ad spots that appear on individual product Listings.

A common myth I see repeated constantly is that TOS always delivers the highest click-through rate (CTR) and CVR, but that’s not universally true. I’ve run ad sets where PDP placements delivered a 12% CVR for the replacement air fryer filters, while TOS only hit 7% CVR for the exact same KeyWord. The difference here is that most shoppers looking for replacement parts are already on the main product Listing when they realize they need a replacement, so they’re further along in the buying journey and ready to convert immediately when they see the ad on the PDP.

If your Listing’s CVR is 20% below your category average, keyword placement efforts will drive a 35%+ higher ACOS on average, regardless of which position you target. That’s because ad position only gets your product in front of shoppers. If your Listing doesn’t convince them to buy, you’re just paying for clicks that don’t turn into sales. I see so many sellers skip optimizing their images, A+ Content, and reviews first, then blame the placement strategy for bad results.

Both private label sellers and arbitrage/wholesale sellers can test placement strategies, just adjust your goals accordingly. For wholesale sellers you’ll likely have less control over Listing optimization, so focus on targeting positions where you have a clear price or review advantage over surrounding competitors on the same search page.

Once you have your Listing performing at or above category average, you can start testing placement strategies. These are the methods I’ve used successfully across multiple sites.

Use the Fixed Bidding strategy in your Sponsored Products campaigns to get the most control over your ad positions. You can adjust the bid multipliers for each of the three placement types to prioritize the positions that work best for your product. For example, if your historical data shows ROS positions deliver a ROAS of 4.2, while TOS only delivers 2.8, you can set a 25% multiplier for ROS positions and a 0% multiplier for TOS to shift more budget to the higher-performing spot.

You can also use dayparting to prioritize positions only during your peak sales windows. For home decor products, most sales happen between 7 PM and 11 PM Eastern Time. I set a 25% multiplier for TOS positions during that window, and a 15% bid reduction for all other hours. This lets me allocate 65% of my daily ad budget to the time when shoppers are most likely to buy, which lifted my overall ROAS by 18% compared to running the same bid all day. You can use the built-in dayparting tools in Seller Central, or third-party tools like Helium 10 or Jungle Scout to automate these adjustments.

For Sponsored Brands (SB) campaigns, you can concentrate budget to TOS positions by setting a base bid, then setting a 50% reduction for all non-TOS positions. For example, if you set a base bid of $1.20, your TOS bid stays at $1.20, while all other positions drop to $0.60. When I tested this for a pet supplies brand, 82% of the SB campaign budget went to TOS positions, and brand search volume increased by 21% in 30 days, as more shoppers saw the brand’s logo and product line at the top of search results.

Before you set any bid multipliers, pull your last 30-day ad placement report from Seller Central. Look at the CVR, ACOS, and Return on Advertising Spend (ROAS) for each placement type for every KeyWord you’re targeting. Don’t just target TOS because that’s what everyone says works. Follow what your data shows, even if that means ROS or PDP positions perform better for your product.

You also want to look at the competitors that show up around your target position. If your product has a lower price, more reviews, or a higher star rating than the other products in that section of the search results, your CVR will be 15% higher on average in that spot. If you don’t have a clear advantage over the surrounding competitors, shift to a different position where you do, or work on optimizing your Listing to gain that advantage first.

Your placement targets should also change based on your product’s lifecycle. I never target TOS for new products in their first two weeks on the market. New products have fewer reviews and lower CVR, so I prioritize ROS positions on pages 2 and 3 first, where CPC is 30% lower than TOS. This lets me accumulate clicks and conversions at a lower cost, while building up social proof. Once the product has 15+ reviews and a CVR at or above category average, I gradually increase the TOS multiplier to move ads to the first page.

Once your organic rank for a KeyWord hits the first page, I test placing the ad position 2-3 spots above your organic rank. This gives you two opportunities to get in front of the same shopper, which lifts overall CTR by 12% on average, as shoppers are more likely to click on a brand they’ve already seen once in the search results.

Amazon’s personalization algorithm means you’ll never get 100% of shoppers to see your ad in your target position for any KeyWord. The algorithm adjusts ad positions based on dozens of factors beyond just your bid, including shopper search history, competitor bids, and Listing performance. Any service or guru that promises 100% placement accuracy is misleading. We ran tests across 6 different North American and European sites, and even with 60% of impressions hitting our target position, we saw a 21% lift in overall ROAS compared to no placement targeting.

Don’t dump your entire budget into a new placement strategy all at once. Test shifting 10-15% of your budget to your target position for 7-10 days first, then adjust based on results. If you don’t see an improvement in ROAS, shift the budget back, or test a different position.

There’s no one-size-fits-all approach to placement strategies. What works for one product or category won’t necessarily work for another, so test small and adjust based on your own data, not what works for other sellers.

At the end of the day, placement strategies are just tactical tools. They can amplify the results of a great product and optimized Listing, but they can’t fix a bad product. I learned this the hard way a few years ago, when I spent $3,000 targeting TOS positions for a phone case product that had a 25% return rate, 15 points above the category average. My ROAS was only 1.1, and I lost $1,800 on the campaign. After we fixed the product quality issue, bringing return rates dropped to 9%, and the same placement strategy delivered a ROAS of 3.7 the next month.

Next time you log into Seller Central this week, pull your last 30-day ad placement report and note which position delivers your highest ROAS. Test shifting 10% of your budget to that position for 7 days, and see how your results change.
