Microsoft Xandr Programmatic Backed by Microsoft's Data
Xandr is Microsoft's programmatic platform — the DSP behind Microsoft Advertising, built on the AppNexus technology and now backed by Microsoft's data and reach. We run it as enterprise programmatic done for performance, not just scale.
Microsoft's programmatic platform
Microsoft Xandr is Microsoft's programmatic advertising platform — the demand-side platform (DSP) at the heart of Microsoft Advertising, built on the AppNexus technology Microsoft acquired and now integrated with Microsoft's broader data, reach, and advertising ecosystem. Xandr management is running enterprise programmatic on this platform well, using its combination of capable programmatic technology, premium inventory access, and Microsoft's data to reach audiences across the open web and beyond.
What distinguishes Xandr is that it pairs serious programmatic technology with Microsoft's scale. The underlying platform comes from AppNexus, a sophisticated programmatic technology, and Microsoft has integrated it with its own data, audience reach, and inventory relationships. For advertisers, that means enterprise-grade programmatic buying backed by the data and reach of one of the largest technology companies — a combination that can be valuable for reaching audiences at scale with the targeting that Microsoft's data enables.
We manage Xandr as a performance channel — running enterprise programmatic on the platform to reach audiences efficiently, using its technology, premium inventory, and Microsoft's data, and holding the spend to genuine outcomes rather than just impressions and scale. The aim is programmatic advertising that performs, leveraging what Xandr's combination of capable technology and Microsoft's backing can offer, run with the rigor that turns programmatic capability into measurable results for a D2C brand.
How we run Xandr
How we manage your Xandr campaigns
Define the objective
We start from the business outcome, because the right Xandr setup depends on whether you want reach, acquisition, or specific audience targeting.
Set up for measurement
We configure campaigns and tracking so the programmatic buying is measurable, not a black box of delivered impressions.
Leverage data and inventory
We use Microsoft's data and the platform's premium inventory to reach the right audiences, the distinguishing advantage of Xandr.
Run enterprise programmatic
We run serious programmatic buying on the platform's capable technology, with the targeting and bidding strategy the goal requires.
Optimize on outcomes
We optimize toward measurable response, holding programmatic to a performance standard rather than chasing impressions and scale.
Capable technology, plus Microsoft's backing
Xandr is worth understanding as the combination of two things: capable programmatic technology and Microsoft's scale behind it. The technology comes from AppNexus, a sophisticated programmatic platform Microsoft acquired, so Xandr isn't a lightweight tool — it's a serious DSP with real programmatic capability. What Microsoft added is its own data, audience reach, and advertising ecosystem, integrating the platform into a much larger whole. For advertisers, that pairing of capable technology with a tech giant's data and reach is the distinguishing proposition.
That combination can be genuinely valuable for the right programmatic needs. Microsoft's data enables audience targeting that smaller platforms can't match, its reach provides scale, and the underlying technology is capable of the serious programmatic buying enterprise advertisers need. Run well, Xandr lets a brand reach audiences across the open web and beyond with the targeting Microsoft's data enables and the inventory access the platform provides — enterprise programmatic backed by the resources of one of the largest technology companies.
As with any programmatic platform, though, the capability and backing only translate into results when the platform is run for performance rather than just scale. A capable DSP with a tech giant's data behind it can deliver impressive reach and impressions that don't convert if it's run as a reach-and-hope buy. The value comes from running it with rigor — proper measurement, audience targeting that uses the data well, and optimization toward genuine outcomes. We run Xandr that way, treating it as the capable enterprise programmatic platform it is and holding it to a performance standard, so its technology and Microsoft's backing produce measurable results rather than just scale.
Enterprise programmatic, run for performance
We run Xandr as the capable enterprise programmatic platform it is, held to a performance standard. Its combination of serious technology and Microsoft's data and reach is a genuine advantage, but capability and backing don't produce results on their own — a powerful DSP with a tech giant's data can still deliver reach that doesn't convert if run as a reach-and-hope buy. We run it with rigor, anchoring everything to measurable outcomes so the platform's strengths translate into real performance rather than just scale.
We leverage what distinguishes Xandr — Microsoft's data and the platform's premium inventory — because that's where its value over a generic DSP lies. Microsoft's data enables targeting that smaller platforms can't match, and the inventory access provides quality reach. We use these deliberately, building audience targeting that draws on the data and placements that reach the right people, so the spend benefits from the Microsoft backing that's the whole point of choosing Xandr rather than just any programmatic platform.
And we're honest about fit and run it within a coherent mix. Xandr is a strong choice for enterprise programmatic needs where its technology, data, and reach fit; it's not automatically the right platform for every brand or goal. We recommend and run it where it genuinely serves your objectives, optimize it toward real outcomes, and position it alongside your other channels — so its enterprise programmatic capability earns its place on results, not on the strength of the Microsoft name alone.
Frequently Asked Questions
Microsoft Xandr is Microsoft's programmatic advertising platform — the demand-side platform (DSP) at the heart of Microsoft Advertising, built on the AppNexus technology Microsoft acquired and integrated with Microsoft's broader data, reach, and advertising ecosystem. It pairs serious, AppNexus-derived programmatic technology with the data and scale of one of the largest technology companies.
Xandr is built on AppNexus, a sophisticated programmatic technology platform Microsoft acquired. So Xandr's underlying technology is the capable AppNexus DSP, now integrated with Microsoft's own data, audience reach, and advertising ecosystem. It's the evolution of AppNexus into Microsoft's programmatic offering — serious programmatic technology now backed by a tech giant's data and scale.

Enterprise programmatic advertising — reaching audiences across the open web and beyond with the targeting Microsoft's data enables and the premium inventory the platform provides. It suits brands with serious programmatic needs that benefit from the platform's technology, data, and reach.

A capable DSP with a tech giant's data behind it can deliver impressive reach that doesn't convert if run as a reach-and-hope buy. We set up proper measurement and optimize toward real results, holding Xandr to a performance standard so its technology and Microsoft's backing produce measurable outcomes.
Microsoft Bing Ads (Microsoft Advertising's search side) is search advertising on the Microsoft search network. Xandr is Microsoft's programmatic DSP — buying display, video, and other programmatic inventory across the open web. They're different parts of Microsoft Advertising: one is search, the other is programmatic. We run both, and they can complement each other within a Microsoft-inclusive advertising strategy.
Not necessarily — it's a strong choice for enterprise programmatic where its technology, data, and reach fit, but not automatically right for every brand or goal. We run it where it genuinely serves your objectives, optimize it toward real outcomes, and position it within a coherent mix alongside your other channels and platforms, so its capability earns its place on results rather than on the Microsoft name alone.
