Microsoft Ads (formerly Bing Ads) serves the Microsoft search network, which skews older, higher-income, and work-context — Bing is the default on Windows and Office devices in many enterprises. For B2B, that audience often over-indexes on actual buyers, and competition is lower than Google, so CPCs and conversion costs are frequently more efficient. Skipping it leaves reachable, high-value demand on the table.
There’s a reflexive snobbery about Bing in marketing circles — it’s the search engine people joke about, the one nobody uses. The data tells a different story, especially for B2B. The Microsoft search network is the default in a huge share of enterprises, baked into Windows and Edge on the work machines where business decisions actually get made. The audience skews older and higher-income, and crucially, your competitors’ reflexive snobbery means they’re not all there bidding against you.

For B2B advertisers, Microsoft Ads is frequently the most under-priced channel available — reachable buyers at lower competition, hiding behind a reputation that’s a decade out of date.
Why the audience matters for B2B
Channel choice is really audience choice. The Microsoft network’s composition happens to line up unusually well with who B2B advertisers are trying to reach. For more on improving your UX, consider the impact of a fast landing page.
| Microsoft Ads audience | Why it matters for B2B | |
|---|---|---|
| Age / income | Older, wealthier | Decision-makers |
| Context | Work devices | In buying mode |
| Competition | Lower | Cheaper clicks |
| Default on | Enterprise Windows | Reaches buyers |
The efficiency advantage
Lower competition has a direct financial consequence: CPCs and conversion costs on Microsoft Ads are often meaningfully cheaper than the equivalent Google campaign. You’re bidding into a less crowded auction for an audience that, for B2B, frequently converts as well or better. The same campaign that’s expensive on Google can be quietly efficient on Microsoft — pure arbitrage while the reputation gap lasts.

How to add it without doubling the work
The practical on-ramp is low-effort: Microsoft Ads lets you import existing Google campaigns directly, so you can launch a parallel program in an afternoon. From there, the discipline is to treat it as its own channel — its own negatives, bid adjustments, and audience nuances — rather than a pure clone, because the audience behaves differently. But the barrier to entry is genuinely small.
Is the volume even worth it?
Microsoft’s search share is smaller than Google’s, so it won’t replace it — the volume is lower. But for B2B, the quality and efficiency of that smaller pool often make it strongly incremental. It’s a complement that captures buyers you were missing, not a primary channel.
The best channels are often the ones everyone else is too cool to use. For B2B, Microsoft Ads is reachable, efficient demand sitting in plain sight — and the reputation that keeps your competitors away is precisely what makes it worth your while.
