Set a Microsoft Excluded Content Term on One Campaign and It Lands on Every Campaign You Run

Microsoft Audience Ads is native inventory. Your ad lands next to somebody else’s headline, and until now you had almost no say in which headline that was. That changed. It matters most to the buyers who run Microsoft as the cheaper second channel and rarely open the account.

What Microsoft changed

Excluded content terms block your ads from showing next to page titles containing words you specify. Microsoft’s documentation gives the example of a tech retailer excluding “faulty tech devices” so its ads stay away from page titles mentioning them (Microsoft Advertising). Search Engine Land reported the rollout on August 5, 2026, and Search Engine Roundtable followed on August 6, crediting the original spot to Hana Kobzová of PPC News Feed. It is arriving gradually, and Microsoft’s own help page still carries the line “Not everyone has this feature yet.”

You get a maximum of 1,000 terms, set at account or campaign level, across Audience, Performance Max, Search and Shopping campaigns. Premium Streaming is not supported yet. To add them: Tools > Content suitability > Excluded content terms > Add, then enter your terms one per line and save.

Why this cuts both ways for a lead buyer

Read Microsoft’s scope sentence carefully, because it is not what the interface implies. In Microsoft’s words, terms “can be added at the account or campaign level, with a maximum of 1000 terms,” and then: “Any terms you add to your campaign will be automatically applied to all campaigns in your account to save you time later.” The Performance Max setup page repeats it.

So the campaign-level box is not a scope. It is an entry point to an account-level list.

The second trap is the category list next door. Through Integral Ad Science, Microsoft already blocks eight categories in audience placements on sites it scores medium or high risk, including adult, gambling, hate speech and violence (content suitability). It also says plainly that it “cannot guarantee that all content exclusions will be blocked.” The seven categories you can opt into are different in kind, and several describe inventory lead buyers actively want. Six of the seven are worth a second look before you tick them.

The pattern is familiar if you watched the placement controls that survived Google’s Display migration: the safest-looking setting is often the one holding your HVAC or health insurance volume.

Navah Hopkins, a product liaison at Microsoft Advertising, makes a related point in Search Engine Journal. Placement-level targeting leans on past performance and on excluding everything else, which she says “can make it harder to uncover new profitable inventory” (Search Engine Journal).

What to change in your account this week

If several verticals share one Microsoft account, the cheapest move is to not use this feature at all. Because the term list is account-wide, it cannot serve a roofing campaign and a health campaign with different inventory needs. You do not have to restructure anything to solve that. Negative keywords sit at campaign level, and website exclusion lists attach per campaign or ad group, so both stay scoped where excluded content terms will not. Splitting accounts is the heavier option, and it costs you a new tracking tag, your conversion history and a fresh learning period, so only do it when a vertical is big enough to deserve its own account anyway.

Then, in order:

1. Open Tools > Content suitability > Content exclusions and read what is already ticked. Somebody may have set it at launch.
2. Add terms for genuine brand damage only. Competitor names, recall language, litigation vocabulary.
3. Leave the opt-in categories off unless a specific category is a real problem for the brand.
4. Check your bid strategy in the same pass. In Performance Max, set Bid strategy to Maximize conversions and attach a Target CPA matching what a qualified call is worth to you, pointed at your UET qualified-lead conversion goal.

That last step matters more than it looks. Microsoft documents that if no conversion goal exists in the account when a Performance Max campaign is created, it converts the bid strategy to Maximize clicks, and only switches to your chosen conversion-based strategy after a conversion goal exists and enough data accumulates (Performance Max setup). Narrowing the context a click-maximizing campaign runs in just buys you narrower clicks.

What excluded content terms do not fix

Microsoft’s own properties stay in the buy. Audience campaigns “will always serve on Microsoft sites (e.g., Microsoft Bing, Microsoft Casual Games, MSN, and Outlook.com) even if you’ve added website exclusions for them” (website control lists). Search campaigns are treated differently, so check which campaign type you are actually arguing with before you conclude the setting is broken.

Microsoft does not name Performance Max in its campaign-level website exclusion list. That page names Audience, Search, Shopping and Lodging. Absence from a help page is not a documented prohibition, so confirm it in your own account rather than assuming either way. Page-title terms are the context lever Microsoft does document for Performance Max.

An audience signal is not a filter. In Performance Max, age and gender are chosen under Demographics inside an audience signal, and Microsoft is explicit about what a signal does: “Your ads may surface to audiences beyond those associated with your audience signal to find more customers and maximize conversions” (audience signals). Setting an age band there tells Microsoft who to go looking for. Read it as a hint, not a boundary, and keep any hard eligibility rule in your screening questions. Update, September 2026: that describes the audience signal, and Microsoft is adding a separate control beside it. Microsoft’s August 2026 product announcement says age and gender targeting exclusions for Performance Max are rolling out now and generally available September 8, letting advertisers explicitly include or exclude age brackets and gender groups (Microsoft product news, August 2026). That is a delivery control, not a hint. The bands do not line up with other platforms, and although Microsoft never ties its separate demographics rule to this feature, we read that rule as closing the lever to insurance and financial advertisers. Confirm it with your Microsoft rep before you switch it on: Microsoft Performance Max age and gender targeting.

Frequently Asked Questions

What is a Microsoft excluded content term?

It is a word or phrase that stops your ads serving next to page titles containing it. Microsoft groups it with website control lists and content exclusions under content suitability. Website exclusions block specific sites, content exclusions block sensitive categories, and excluded content terms work on the page title itself. Microsoft’s own example is a tech seller excluding “faulty tech devices” so its ads avoid pages about them.

How many excluded content terms can I add?

A maximum of 1,000. Microsoft’s documentation states they can be added at the account or campaign level with that cap. The limit is generous enough that it will rarely be the binding constraint. What bites first is the scope: anything added at campaign level is applied to every campaign in the account, so the useful discipline is keeping the list short and defensible rather than filling it.

Do excluded content terms apply to Performance Max?

Yes. Microsoft lists content suitability as available for Audience, Performance Max, Search and Shopping campaigns. Inside Performance Max they appear during campaign creation under Targeting settings as “context exclusions”, alongside negative keywords. Microsoft also offers a prompt-based option that generates negative keywords and excluded content terms for you, which you can edit or remove afterwards.

Can I stop my ads showing on MSN or Outlook?

Not in an Audience campaign. Microsoft states those will always serve on Microsoft sites including Bing, Microsoft Casual Games, MSN and Outlook.com even when you have added website exclusions for them. Search campaigns get more room: Microsoft says you cannot block Bing, AOL or Yahoo search traffic there, but you can block audience traffic including MSN, Microsoft Edge and Outlook.com (exclusions guide). Microsoft caps website exclusions at 2,500 URLs.

Do age and gender settings limit who sees my Performance Max ads?

Not the ones inside the audience signal. In Performance Max, age and gender are chosen inside an audience signal under Demographics, and a signal is an input to Microsoft’s optimization rather than a restriction. Microsoft warns directly that ads may surface to audiences beyond the signal in order to find more customers. Treat those fields as a hint about who to look for, and put any real eligibility boundary into your screening questions instead. Microsoft’s August 2026 announcement adds separate age and gender exclusions from September 8, and those do limit delivery.

The scope question comes before the word list

Most of the argument about this feature will be about which words to block. The words are the easy part, and you can revise them any afternoon. What decides whether this control protects you or quietly starves your best campaigns is a scope question instead: how many different businesses are living inside that one Microsoft account. Answer that first. If the answer is more than one, the right number of excluded content terms might be zero.
