Microsoft Ads

Also called Bing Ads

By the AdFlint research team · Last reviewed July 2026

Search advertising on Bing, Yahoo, DuckDuckGo, and partner sites, formerly called Bing Ads, with an import path from Google Ads campaigns.

The search network formerly known as Bing Ads, covering Bing, Yahoo, DuckDuckGo, and syndicated partners, plus LinkedIn profile targeting that search rivals do not offer. Volume is far smaller than Google's, though competition is often lighter and the audience skews older and more desktop-heavy. The typical error is importing Google campaigns once and never maintaining them, so budgets and negatives drift apart.

Key takeaways

  • The Google Ads import is a one-time copy by default, not a live sync, so budgets and negative keywords drift apart unless someone maintains both accounts.
  • LinkedIn Profile Targeting is Microsoft-exclusive and worth using for B2B campaigns, since no rival search engine offers it.
  • Judge Microsoft Ads on CPA and ROAS rather than raw traffic volume - its total search volume is inherently smaller than Google's.
  • The UET conversion tag is separate from Google's tag and must be installed and configured independently for reporting to mean anything.

In practice.

Microsoft Ads runs on a search auction that spans Bing itself plus syndicated partners - Yahoo, DuckDuckGo, AOL, Ecosia - along with the Microsoft Audience Network, which places native-style ads on MSN, Outlook, and Edge outside of search results entirely. Campaign types closely mirror Google Ads: Search, Shopping (built on a Microsoft Merchant Center feed), Performance Max, Audience ads, and App campaigns. The parallel structure is deliberate - Microsoft built the platform to be a comfortable second home for advertisers already running Google Ads, down to matching campaign settings and bid strategy names wherever it could.

The Google Ads import tool is the fastest way into the platform: it pulls campaigns, ad groups, keywords, ads, negatives, and even Smart Bidding history from a connected Google Ads account in one pass. What it does not do by default is keep syncing - it's a one-time snapshot, not a live mirror. Ongoing sync has to be triggered manually or scheduled through the import tool's re-import option; otherwise every negative keyword added, every budget change, every new ad written afterward in Google Ads exists only in Google Ads. LinkedIn Profile Targeting is the platform's genuinely unique layer: it overlays company, industry, job function, and company size data from LinkedIn onto Bing search campaigns, letting an advertiser bid up or restrict delivery by professional profile in a way no other search engine offers.

Microsoft Ads earns dedicated maintenance time once an account has matured past initial testing and spend is material enough that even a smaller pool of search volume moves the needle - or when the audience is B2B or professional enough that LinkedIn Profile Targeting adds real precision. It's less worth the effort for very small accounts or hyper-local categories where Bing's older, more desktop-heavy user base doesn't match the buyer profile as well as it might for other verticals.

The most common mistake is treating the import as a one-time task rather than an ongoing sync obligation: budgets, negative keyword lists, and even bid strategies drift apart between the two accounts within weeks if nobody revisits Microsoft after the initial import. A second common mistake is judging Microsoft Ads by comparing raw traffic volume to Google - the total addressable search volume on Bing and its partners is inherently a fraction of Google's, so lower absolute numbers are expected and not a sign something is broken. A third is skipping the UET (Universal Event Tracking) tag setup because "conversion tracking was already done in Google Ads" - the UET tag is entirely separate and has to be installed and configured with its own conversion goals for Microsoft Ads to report meaningful results at all.

In reporting, segment by network - Bing owned-and-operated versus syndicated partners versus the Audience Network - since traffic quality and cost can vary meaningfully across those three, and a low blended cost per click can mask one segment performing far worse than the others. UET-based conversion counts won't line up one-to-one with Google Ads conversions even for identical actions, because attribution windows and cross-device modeling differ between the two platforms - compare Microsoft Ads performance against its own historical baseline and CPA target, not against Google's exact numbers.

Worked example

How an unmaintained import quietly leaks spend

Suppose you import a Google Ads campaign into Microsoft Ads on July 1, both running at $50 a day with the same keyword list and negatives at the time of import. Over the following two months, the Google Ads search term report surfaces 12 junk queries worth blocking, and you add them as negatives there - Google's wasted spend on those terms drops close to zero.

Because the Microsoft Ads side was never re-synced, those same 12 queries are still eligible to trigger ads there in September. If Microsoft's blended cost per click for those terms runs around $2.10 and they're generating roughly 40 clicks a month with no conversions, that's about $84 a month leaking through Microsoft Ads alone - money Google Ads stopped spending on the identical problem two months earlier, simply because the negative list only existed on one side of the import.

The settings this gets confused with, and how to tell them apart.

Common questions.

Does importing from Google Ads keep syncing automatically after the first import?

No - the default import is a one-time snapshot. Ongoing sync has to be manually triggered or scheduled through the import tool's re-import option, or changes made in Google Ads afterward will never reach Microsoft Ads.

Why is my Microsoft Ads traffic volume so much lower than Google Ads?

Bing and its syndicated partners command a much smaller share of overall search volume than Google, so lower absolute traffic is expected even in a well-optimized account. Evaluate the account on cost per acquisition and ROAS rather than comparing raw impression or click counts to Google.

What is LinkedIn Profile Targeting in Microsoft Ads?

It's an audience layer unique to Microsoft that overlays LinkedIn's company, industry, job function, and company size data onto Bing search campaigns, letting you target or bid-adjust by professional profile. No competing search engine offers an equivalent.

Do I need a separate conversion tag for Microsoft Ads, or does my Google tag carry over?

You need the UET (Universal Event Tracking) tag, which is entirely separate from Google's conversion tracking and has to be installed and configured with its own goals. Conversion counts between the two platforms won't match exactly even for the same action, because attribution windows and cross-device modeling differ.
