Most brands spend their time optimizing the hero product – the case, device, machine, supplement, or tool that drives most of their revenue. But on Amazon, a lot of profit sits around the edges: ancillary products that complete the setup, protect the main item, or make it easier to use.
Think: screen protectors with tablets; filters with coffee machines; refill packs with dispensers; straps with cases; cleaning kits with equipment.
Amazon gives you a surprisingly rich toolbox to increase the “attach rate” of those ancillary products – but only if you set your catalogue and content up to support that behaviour.
This article looks at how to think about ancillary products strategically, and which Amazon tools you can use to sell more of them without feeling pushy or confusing.
Start by defining your ecosystem, not just SKUs
Before you touch any levers, it’s worth mapping your catalogue like an ecosystem.
What is the hero product (or products) people usually discover first? Which products protect, refuel, upgrade or customise those heroes? Which products are natural next steps after the first purchase?
Write this down in plain language. For example: “Main product: standing desk. Ancillaries: CPU holder, cable management tray, anti-fatigue mat, monitor arm, under-desk drawer.”
When you see it as an ecosystem, it becomes much easier to decide what to bundle, what to recommend, and where content and promotions should point.
Use bundles to package value, not just to stick SKUs together
Amazon offers different ways to present grouped products: virtual bundles (for brand-registered sellers), physical bundles or multipacks, and variations where it makes sense.
Bundles work best when the shopper feels you’ve done the thinking for them. The goal is not to cram as much into a bundle as possible. It’s to create combinations that feel obvious and helpful: a “starter kit” with everything needed to get full value from the hero, a “pro kit” or “family pack” tuned to a specific user, or a “refill pack” that makes repeat purchase easy and economical.
Bundling works best when the shopper feels they’re getting a complete, coherent solution – not random extras.
Let content do the heavy lifting for cross-sell
Your product pages and Store are often the best place to educate shoppers about ancillary products. Done well, content can make cross-sell feel like part of the story, not a hard pitch.
A few high-impact areas: A+ comparison tables to show how your products relate to each other; “complete the setup” sections in A+ or Store pages that highlight recommended add-ons; and contextual images where the ancillary product is clearly visible alongside the hero (case on the phone, mat under the desk, filter in the machine).
Featuring secondary products visually, in context with the main product, helps shoppers picture the whole solution.
Use promotions to gently nudge attachment
Promotions can be a powerful nudge for ancillary products, especially when they’re easy to understand and aligned with how people naturally buy.
Instead of discounting your hero product heavily, consider “buy X, get Y at a discount” (e.g. buy the camera, get 20% off the bag), coupons only on the accessory so adding it feels rewarding, or time-bound deals on bundles that make the complete solution feel like a smart buy.
Promos should make the decision to add the ancillary item feel like the most rational choice, not a complicated puzzle.
Make ads and remarketing work for the ecosystem
Sponsored Products and Sponsored Brands are often used only to push the main ASIN. Ancillary products can benefit from a more nuanced approach.
Use Sponsored Products to target your own hero ASIN with its main accessory, and, where truly relevant, competitor hero ASINs as well. Use Sponsored Brands and Store spotlight to show the system (e.g. “Desk + Mat + Monitor Arm”) and drive to a Store page laid out as a “complete workspace” or “full setup”.
Retarget recent buyers of the hero product with ads for key accessories 7–30 days after purchase, when interest or need is highest. The objective is to think beyond “what product am I advertising?” to “where is this buyer in their lifecycle, and what’s naturally next?”
Keep an eye on attach rate and feedback
Treat ancillary sales as something you measure, not just hope for. Track attach rate for key SKUs (how often product B sells with product A), bundle performance versus individual items, and recurring review or Q&A themes where customers ask “does this work with…?”.
If customers consistently buy an unofficial accessory with your hero product, that’s a signal: either you should offer your own version or improve how you present your ecosystem.
Selling ancillary products well on Amazon isn’t about pushing random extras. It’s about designing and communicating a complete solution around your core offer – and then using Amazon’s tools (bundles, content, promos and ads) to make that solution obvious and easy to buy.
