If you sell into businesses on Amazon, 2025 is a pivotal year. Amazon Business has quietly grown into a huge B2B marketplace, with buyers who order in bulk, convert at higher rates, and return less often than consumers. But until recently, your Amazon ads more or less treated them exactly the same as everyday shoppers.
That’s changing. Amazon has introduced B2B-only Sponsored Products campaigns and Amazon Business bid adjustments, and it’s given more control in DSP through bid modifiers. In plain terms: you can now treat B2B buyers as a distinct audience, with their own budget, bids, and strategy, instead of letting them disappear into blended consumer data.
This article walks through how to use those tools to grow B2B sales without turning your ad account into a monster.
Why does B2B needs its own Amazon strategy?
Business buyers don’t behave like consumers. They buy in larger quantities, often on behalf of a team or multiple locations. They care about reliability, standardisation, and total cost of ownership. And when they find the right product, they tend to reorder.
All of that means a click from an Amazon Business account is typically worth more than a normal retail click. If you lump both together, your reporting hides that fact and you’re likely under-investing in the customers who drive the best economics.
The new B2B ad tools are really about surfacing and acting on that difference.
Start with B2B-only Sponsored Products
The headline change is the ability to run Sponsored Products campaigns that target only Amazon Business customers. Instead of competing in the same auction for someone buying a single unit and someone buying 50, you can carve out a campaign that serves only verified business buyers.
In practice, a simple starting point is to identify a handful of ASINs that already show strong Amazon Business behaviour – large quantity orders, frequent reorders, obvious business use cases – and clone your best-performing campaigns for those products as B2B-only versions. Keep the structure similar, but watch performance separately. You’ll usually see differences in conversion rate and average order value quite quickly.
This doesn’t replace your existing campaigns. It adds a clean lane for business traffic, so you can decide later how much budget you want to dedicate to it.
Use Business bid adjustments instead of blindly raising bids
Alongside B2B-only targeting, Amazon now lets you apply bid adjustments for Business placements. That means you can raise bids specifically when the impression is going to an Amazon Business context, without cranking up bids for consumer traffic at the same time.
The practical benefit is simple: if business buyers convert better and buy in larger quantities, you can afford to pay more to reach them – but you don’t have to overspend on everyone else.
A sensible approach is to start with modest positive adjustments on your B2B-relevant campaigns and see how ACOS and ROAS shift on the business side. If the numbers look healthy, you can lean in further. The goal is not to throw huge bids everywhere; it’s to direct existing spend toward the buyers who matter most.
Let DSP do the higher-funnel B2B work
If you’re using Amazon DSP, the newer bid modifiers give you another way to tune B2B performance. Instead of treating all impressions equally, you can raise or lower bids based on audience characteristics and inventory that skew toward business buyers.
This is where DSP starts to look more like account-based marketing than generic display. You can reach procurement teams and influencers off Amazon – on sites and apps they use – then let Sponsored Products and Sponsored Brands do the heavy lifting when they return to search and product pages.
You don’t need an elaborate setup. Even a simple pattern where you bid a little more for audiences built from Amazon Business behaviour, and a little less for obviously consumer-heavy inventory, can make DSP more B2B-conscious.
Make sure your offer actually works for business customers
The ad tools only help if business buyers like what they see when they land on your pages. That means using Amazon Business features properly: business pricing, quantity discounts, and, where appropriate, business-only offers. It also means shaping your content to the concerns of someone buying for a team, not themselves.
Instead of leading with lifestyle angles, emphasise reliability, compatibility, and standardisation. Show how one SKU can cover multiple roles, how the product reduces downtime or replacement cycles, and how easy it is to reorder. If you use Sponsored Brands or Stores, consider a business-focused landing page that surfaces bulk packs, bundles and accessories needed for rollouts.
Measure B2B performance as its own track
The final step is to stop treating B2B sales as “just part of Amazon”. Once you have B2B-only campaigns or Business bid adjustments live, make a habit of reviewing B2B performance separately from consumer results.
A simple monthly rhythm works well: look at B2B sales, conversion rate and average order value for your key ASINs; compare how B2B-only campaigns or Business placements perform vs your blended campaigns; and move budget gradually towards the areas where business customers are clearly delivering better returns.
That doesn’t require a complex dashboard; it just requires the habit of asking, “How is our B2B side doing?” instead of only chasing total sales.
Bringing it together
Boosting B2B sales on Amazon in 2025 isn’t about inventing a brand-new playbook. It’s about finally giving business buyers their own space inside your existing one.
B2B-only Sponsored Products campaigns, Business bid adjustments, and smarter DSP bidding let you isolate, understand, and grow the part of your Amazon business that is often more profitable per click. Combined with business-ready offers and straightforward, professional messaging, those tools turn B2B from a hidden bonus into a deliberate growth engine.
