Search campaigns on Microsoft Ads perform well for high-intent traffic. Once you've built a solid search foundation, the next question is whether the Microsoft Audience Network deserves a slice of the budget — or whether that spend is better allocated elsewhere. The honest answer depends on your conversion goals, creative readiness, and how much data you already have in the account.
This guide covers what the Audience Network actually is, how it compares to the Google Display Network, when it performs and when it doesn't, and how to structure campaigns if you decide to test it.
What the Microsoft Audience Network Actually Is: Placements, Publishers, and Reach
The Microsoft Audience Network is a native/display advertising network that serves ads across MSN.com, Outlook.com, Microsoft Edge's new tab page, and a curated set of premium partner publisher sites. These placements are entirely separate from Microsoft search inventory — different auction, different ad formats, different targeting logic.
Ad formats on the Audience Network are native: headline, description, and image that render to match the surrounding content style. Unlike standard display banner ads, these units blend into editorial content rather than appearing as distinct ad containers. On MSN and Outlook specifically, this means your ads appear alongside news articles and inbox content that Microsoft's user base engages with daily.
Understanding how Microsoft Audience Network fits into the broader Microsoft Ads platform is useful context before allocating budget here. The Audience Network is set up at the campaign level — you can't simply opt into it from a search campaign without understanding that it operates with different performance characteristics.
Reach is meaningful but not enormous. Microsoft doesn't publish precise monthly user figures for the Audience Network, but the combination of MSN's news readership, Outlook's email users, and Edge's browser install base represents a substantial volume of professional and consumer impressions. The audience skews similar to Bing search demographics: older, higher-income, with stronger representation in professional categories.
Microsoft Audience Network vs Google Display Network: Key Differences
| Microsoft Audience Network | Google Display Network | |
|---|---|---|
| Ad format | Native only | Banner, responsive display, native |
| Primary placements | MSN, Outlook, Edge, select publishers | 3M+ websites and apps |
| Reach | Moderate | Very high |
| CPM/CPC | Generally lower | Varies widely |
| Audience targeting | In-market, remarketing, LinkedIn profile, customer match | In-market, remarketing, lookalike, custom intent |
| Brand safety | High (curated placements) | Variable (requires exclusion management) |
The key difference in favor of Microsoft Audience Network is brand safety and placement quality. Serving on MSN and Outlook is predictable — you know the content environment. Google's Display Network spans millions of sites and apps, which requires active placement exclusion management to avoid low-quality inventory. Microsoft's network is smaller but more controlled.
The key difference in favor of Google's network is scale. GDN can reach significantly more users, which matters for top-of-funnel campaigns where volume is the primary objective. For how B2B marketers extend reach beyond search using the Audience Network, the LinkedIn profile targeting layer on Microsoft is a genuine differentiator — but the raw reach ceiling is lower than Google's.
When the Audience Network Performs Well (and When to Exclude It)
The Audience Network performs best when:
You have strong remarketing lists. Retargeting is the clearest use case. Users who visited your site or engaged with your content are already warm. Serving native ads to them on MSN or in Outlook reinforces brand presence without the high CPCs of search remarketing. For this to work, your UET-based remarketing lists need to be large enough — at minimum a few hundred users, ideally several thousand.
You're running upper-funnel awareness for a B2B product. The professional audience composition of MSN and Outlook aligns well with enterprise and mid-market B2B products. If your product sells to finance, IT, or professional services buyers, Audience Network placements are more likely to reach them in a relevant context than generic display inventory.
Your creative is production-quality. Native ads live or die by their image and copy quality. A generic stock photo with bland copy will get ignored. If you can produce editorial-style images that don't look like ads and copy that reads like content, the format has real potential.
The Audience Network performs poorly when:
- Your account has low conversion volume and smart bidding doesn't have enough signal
- You have no remarketing lists and are targeting cold audiences with bottom-funnel conversion goals
- Your product requires immediate high-intent action — the Audience Network is a context for browsing, not active search
When in doubt, run the Audience Network in a separate campaign (not opted into from a search campaign) so you can isolate its performance data. Exclude it from existing search campaigns if you see CPA deterioration, and re-evaluate as a standalone test with its own budget.
How to Set Up Audience Network Campaigns: Targeting, Creatives, and Budgets
Targeting options
The Audience Network supports the same audience targeting types as Microsoft search: remarketing lists, in-market audiences, customer match, and LinkedIn profile targeting. For cold audience campaigns, in-market audiences and LinkedIn profile data are the most structured starting points.
Applying LinkedIn profile targeting to Audience Network campaigns is one of the more differentiated capabilities Microsoft offers — you can target by job function, industry, and seniority even in display/native contexts. For B2B brands, this means you're not just buying impressions on MSN; you're buying impressions specifically from people who match your target buyer profile.
Creative requirements
Each Audience Network ad needs a landscape image (minimum 703x368 pixels; 1:1.91 aspect ratio recommended), a short headline (up to 25 characters for native), a long headline (up to 90 characters), and a description (up to 90 characters). Providing multiple creative variants is strongly recommended — the platform will optimize delivery toward better-performing assets.
Image quality is critical. Microsoft's editorial standards for Audience Network are stricter than standard display. Avoid text overlays on images, avoid overly promotional imagery, and use high-resolution photos that look like editorial content rather than advertisement assets.
Budget and bidding
Starting budgets for Audience Network testing should be modest — $500-$1,000/month is enough to generate meaningful CPM and CPA data. For bidding, target CPA (if you have sufficient conversion history) or enhanced CPC are the most practical starting points. Which bidding strategies work best for Audience Network placements depends on campaign maturity and conversion volume; automated bidding needs data to optimize, so new campaigns often start with enhanced CPC before transitioning.
Keep Audience Network campaigns in separate campaign structures from search. Mixing them complicates performance analysis and can cause budget allocation to drift in ways that are hard to diagnose. For how to analyze Audience Network performance in Microsoft Ads reports, pull placement-level performance data to see which specific publishers are driving conversions versus spending budget inefficiently.
Our Verdict: Budget Allocation Guidelines for Search vs Audience Network
The Audience Network is not a required component of a Microsoft Ads strategy. For most accounts, search should be funded first and fully before any display or native budget is allocated.
If you're not yet hitting your search CPA targets, the Audience Network is a distraction. Fix search first.
Once search is performing, a reasonable test framework:
- For remarketing campaigns: Allocate 10-15% of search budget to a separate Audience Network retargeting campaign. This is the highest-probability use case and worth testing in almost any account with reasonable traffic volume.
- For B2B awareness: If your product targets professional audiences and your search brand volume is growing, a small Audience Network awareness budget (5-10% of total account spend) can supplement upper-funnel reach. Set brand recall and engagement metrics as the evaluation criteria, not direct conversion CPA.
- For direct response with cold audiences: Approach with skepticism. The Audience Network can work for this, but requires strong creative, good audience targeting, and patience. Start with $500-$1,000 in a controlled test before scaling.
Exclude the Audience Network from search campaigns entirely until you're running it intentionally as a separate campaign type. The default opt-in behavior during campaign setup can commingle your search budget with Audience Network spend in ways that are difficult to unpick after the fact.
Frequently Asked Questions
What Is the Microsoft Audience Network?
The Microsoft Audience Network is a native advertising network that serves ads on MSN, Outlook.com, Microsoft Edge, and partner publisher sites. It uses native ad formats (image, headline, description) rather than standard display banners, and supports audience targeting including remarketing, in-market segments, customer match, and LinkedIn profile data.
Is the Microsoft Audience Network Worth Using for B2B?
For B2B advertisers with established remarketing lists, yes. The combination of professional audience demographics and LinkedIn profile targeting makes the Audience Network more relevant to B2B buyers than most display networks. For cold audiences, it's worth a small controlled test but requires strong creative and realistic conversion expectations.
How Does the Microsoft Audience Network Compare to the Google Display Network?
Microsoft's Audience Network is smaller in reach but more controlled in placement quality. Ads serve on a curated set of premium publishers (MSN, Outlook, Edge) rather than the millions of sites in Google's network. CPMs are generally lower, brand safety is higher, and the LinkedIn targeting capability is unique. Google's network wins on scale; Microsoft's wins on targeting precision and placement predictability.
How Much Should I Budget for the Microsoft Audience Network?
Start with a small test budget — $500-$1,000/month — to establish baseline CPM and CPA benchmarks. Run it as a separate campaign from your search activity so performance data stays clean. Remarketing campaigns are the highest-probability starting point; scale from there once you have conversion data to support the decision.
