About this video
In this video, we share one obvious example of competition on Amazon and how it affects your conversion rates. When sellers do their product research, in most cases one part of their decision-making process is looking at BSRs of most similar competing products. If it fits a certain range then they consider it.
As someone who works with a lot of data on a daily basis, I know how easy it is to get lost in details and oversee the bigger picture. It sometimes becomes hard to look at your prospective market as a whole. What I mean by that is - how many other ways are there, aside from your product, to solve the same problem to your customer?
On an example of the cat scratching post product, we explain why these sellers have to fight for the same customer with other sellers who sell a completely different product - furniture cover.

Frequently asked questions
Q: Why is BSR alone not enough to assess competition during Amazon product research?
A: BSR tells you how well a product is currently selling relative to others in its category, but it does not tell you the full picture of who you are actually competing against for the same customer. Two products can have strong BSR numbers and appear to serve different niches while targeting the same underlying buyer problem. If your product and a structurally different product are both solving the same problem, you are competing for the same purchase decision, and that competition will affect your conversion rate in ways BSR data will never reveal.
Q: What is substitute competition on Amazon and why does it matter?
A: Substitute competition refers to products that are different from yours in form but address the same customer problem. The example from the video illustrates this clearly: a cat scratching post and a furniture cover are different products, but both solve the problem of a cat destroying furniture. A customer who buys the furniture cover is unlikely to also buy the scratching post, which means both product types are competing for the same single purchase. Understanding substitute competition matters because it directly affects your conversion rate and your PPC efficiency, since you may be bidding against keyword universes that pull the same audience in a different direction.
Q: How do I identify substitute competition for my product before launching?
A: Start by framing the core problem your product solves, not just the product category it belongs to. Then ask: what other products exist on Amazon that a shopper might buy instead to solve that same problem? Search for those alternative solution types and look at their BSR, review counts, and the keywords they rank for. If strong alternatives already exist with large sales volumes and high review counts, that is a signal your addressable market is smaller than the raw keyword demand suggests, because a portion of that demand will convert on the alternative solution rather than yours.
Q: How does substitute competition affect PPC conversion rates and ACoS?
A: When substitute products exist and are actively ranking for adjacent or overlapping keywords, a portion of your paid traffic will come from shoppers who are still evaluating both solutions. These shoppers are less decided and therefore less likely to convert, which pushes your conversion rate down and your ACoS up. If you are running a launch campaign and your ACoS stays consistently high despite good listing quality and competitive pricing, this is one of the patterns worth investigating: the buyer pool for your target keywords may be split between your product and a different category of solution.
Q: Should substitute competition change my product selection decision?
A: It should change how you evaluate the potential of a product, not necessarily eliminate it. The key question is whether customers in your target market are likely to buy multiple solutions to the same problem, or whether they will commit to one and stop. In categories where buyers tend to layer solutions, such as pet care, substitute competition is less damaging. In categories where a buyer makes one purchase decision and moves on, such as a single-use tool or a one-time accessory, substitute competition directly reduces your effective market size and makes profitable scaling harder to achieve.
