Microsoft Ads in 2026: The Audience Most Agencies Are Still Ignoring

Most agencies treat Microsoft Ads as an afterthought, a box to check once the Google budget is set rather than a channel with its own audience worth planning for on purpose. That is a pricing decision as much as a strategy one: the audience Bing actually reaches is measurably different from Google's, and the clicks are measurably cheaper, which makes skipping it by default an easy way to leave qualified traffic on the table for a client who would pay less to reach it.

The audience is not a smaller version of Google's

Searchlab's 2026 Microsoft Ads statistics roundup puts the core demographic gap in concrete terms: the largest age group on Bing is 35 to 54 at 42% of users, an eight-point gap above the same bracket on Google. Forty percent of Bing users report household income above $75,000, against 31% on Google, and 46% hold a college or university degree versus 38% on Google. On device, 68% of Bing desktop users run Windows, which lines up with where a lot of B2B purchasing research and procurement actually happens: at a work desktop, on a browser tied to a Microsoft-managed environment, during business hours.

Cheaper clicks are not a coincidence

The same data set puts average U.S. CPC at $1.37 on Microsoft Ads against $2.06 on Google Ads, a roughly one-third discount driven by lower competition in the auction rather than lower ad quality requirements. That gap widens further in specific verticals; legal services shows the steepest difference in Searchlab's data, with Microsoft Ads running notably below Google on comparable keyword sets. Lower competition also means an agency's existing Google keyword and ad copy work, the part that actually took the effort to build, transfers over largely intact rather than needing to be rebuilt from scratch for a second platform, especially given the platform's own import tooling built for exactly that move.

Performance is not uniformly better, and it does not need to be

The full picture is more mixed than 'cheaper clicks' alone suggests, and it is worth quoting the mixed parts too. Searchlab's data puts average conversion rate at 3.6% on Microsoft Ads against 4.2% on Google, a real gap in the other direction. But cost per conversion still favors Microsoft at roughly $31 versus $45, and reported ROAS averages 2.8x against 2.0x on Google, because the lower cost per click more than offsets the softer conversion rate on a per-dollar basis. The accurate pitch to a client is not that Microsoft Ads converts better, it is that a dollar goes further there for the right audience, which is a different and more defensible claim.

A worked example: what shifting a share of a $20,000 Google budget looks like

Running the cost gap through an actual number makes the case less abstract. A client spending $20,000 a month on Google Search at the $2.06 average CPC Searchlab reports is buying roughly 9,700 clicks a month at that blended rate. Moving a modest $3,000 slice of that budget to Microsoft Ads at the $1.37 average CPC does not just save money on the clicks it replaces, it buys roughly 2,190 clicks with that same $3,000, more than the 1,456 clicks the same dollars would have bought staying on Google. The other $17,000 keeps running on Google exactly as before, so the comparison is a real incremental-volume test against the account's own numbers rather than a theoretical claim. None of this assumes Microsoft's audience converts at the same rate; Searchlab's own data puts conversion rate lower on Microsoft, so the number that actually settles the test is cost per conversion over the pilot window, not raw click count, but the click math is what makes the pilot worth running in the first place.

Where the legal services vertical fits especially well

Legal services is worth calling out specifically because it shows the widest CPC gap in Searchlab's vertical breakdown, and the reasons line up with everything else this data says about who is actually on Bing. A family law or personal injury firm's buyer, someone researching a serious decision at a work desktop or a home computer running Windows, often during business hours, is close to a direct match for the demographic profile above: older, more likely to hold a degree, more likely to sit above the $75,000 household income line. That overlap plus the wider cost gap in the vertical is why a law firm client is a stronger candidate for a Microsoft Ads pilot than, for example, a mobile-first DTC brand chasing impulse purchases, where the Bing audience skew works against the buyer rather than for it. Conduit's own industry work in legal reflects the same pattern: the channels that reach a considered, higher-value legal decision tend to reward exactly the kind of desktop-based, research-heavy behavior Bing's audience over-indexes on. The same logic extends to any practice area built on a slow, research-heavy decision rather than an impulse purchase, estate planning, immigration, and business litigation among them, where the buyer's actual behavior looks a lot more like the Bing demographic profile than the Google-first assumption most agencies default to.

Setting up conversion tracking correctly before trusting any of these numbers

Microsoft Ads' own conversion tracking tag is a separate implementation from Google's, and a surprising number of accounts run for weeks with it missing from a thank-you page or a lead-confirmation screen because the assumption was that importing a campaign also imported its tracking. It does not. Before trusting a single number in this article for a specific account, the tag needs to be verified against the actual conversion event, not just page load, and checked again after any site redesign or landing page change, since a tracking tag living in a page template is exactly the kind of thing a developer removes by accident during an unrelated update.

• Confirm the conversion tag fires on the actual conversion event, not just on page load
• Cross-check a sample of Microsoft-attributed leads against GA4 or the client's CRM to confirm the two systems agree
• Re-verify tag placement after any site redesign, landing page change, or CMS migration

An account reporting a suspiciously low cost per conversion in the first month is worth checking for a tracking gap before it gets reported to a client as a win, since an undercounted conversion count will make the platform look better than it actually performed.

Copilot is pulling search behavior into Microsoft's ecosystem too

The audience case is not static either. Searchlab's 2026 data reports 320 million monthly Copilot users, up 148% year over year, with 35% of Copilot sessions showing purchase intent against 22% for standard search queries. That is a meaningfully higher share of commercial intent flowing through a Microsoft-owned surface than through a typical search session, and it is growing fast enough that an agency treating Microsoft Ads as a static, minor channel is underweighting where a real slice of future search and AI-assisted shopping behavior is heading, not just where today's click volume happens to sit.

Reach beyond search: the Microsoft Audience Network

Search is not the only inventory. Microsoft's own Audience Network overview reports reach across Microsoft Edge, Outlook, MSN, and Microsoft Casual Games at roughly 1 billion customers, and cites users exposed to these native and display placements as three times more likely to search a brand's name, four times more likely to visit the brand's site, and six times more likely to convert, compared to users who were not exposed. That is a remarketing and awareness layer riding on top of the same account structure as the search campaigns, with no additional platform to learn.

Why this isn't showing up in most agency proposals

None of this is a secret. WordStream's own 2026 Google Ads benchmark report is built from over 13,000 search campaigns spanning both Google Ads and Microsoft Ads, which means the benchmark data an agency is probably already reading includes Microsoft performance without most readers noticing the platform split. The gap is operational, not informational: running a second platform means a second dashboard, a second set of conversion tracking checks, and a second line in the monthly report, and most agencies do not add that overhead unless a client specifically asks for it or the Google budget has clearly hit a ceiling.

What has to be set up before any of this data means anything

None of these numbers apply automatically the moment an account opens. Microsoft Ads runs its own conversion tracking tag, separate from Google's, meaning conversion data does not appear until it is implemented and verified on the client's site, and campaigns need their own creative, ad copy, and keyword build even when imported from an existing Google account, since Microsoft's own import guidance recommends reviewing everything after an import completes rather than assuming a perfect one-to-one copy. The audience and cost advantages above are real, but they only show up in an account that has been set up and verified properly, not by default the moment campaigns go live.

The objection worth pre-empting before it comes up

The most common pushback is some version of 'my client doesn't care about Bing,' which misreads what is actually being proposed. No agency is suggesting Microsoft Ads replace Google as the primary search channel; the case is incremental reach into an audience segment Google's own auction is not fully capturing, at a lower cost, running alongside the existing account rather than instead of it. Framed as an addition to an already-working Google account rather than a competing recommendation, the objection mostly resolves itself once the demographic and cost data above are actually on the table in front of the client.

For B2B, professional services, and higher-ticket verticals where the Bing demographic skew lines up directly with the buyer, that operational overhead is worth carrying. Conduit's white label Microsoft Ads team runs it as a standard extension of an existing white label PPC account rather than a separate project, so an agency can add the channel without adding a second workflow to manage.
