Demographic targeting: age and gender modifiers
Microsoft Advertising allows direct demographic bid adjustments on Search campaigns. Here is how to adjust bids across age brackets and gender tiers.
How Microsoft identifies age and gender demographics#
Unlike cookie-dependent estimation models, Microsoft Advertising leverages authenticated user demographic data from millions of signed-in Microsoft Accounts across Windows, Outlook.com, Xbox, and Microsoft 365.
As explained in Microsoft Demographic Targeting Docs, 2026, authenticated signals provide superior precision for age and gender attribution.
Supported age brackets and gender tiers#
Advertisers can set independent bid adjustments from -90% to +900% (or -100% exclusion) across seven standardized age brackets and two gender classifications:
- Age Groups: 18-24, 25-34, 35-49, 50-64, 65+, and Unknown.
- Gender Tiers: Male, Female, and Unknown.
B2B and high-ticket demographic optimization#
The Microsoft search audience skews older and wealthier than other search engines. For luxury goods, wealth management, and senior B2B decision-makers, boosting bids on the 35-49 and 50-64 brackets (+30% to +50%) captures top-tier commercial volume as documented in Microsoft Demographic Solutions, 2026.
Handling the Unknown demographic segment#
Never set a -100% exclusion on the 'Unknown' age or gender segment. 'Unknown' represents users searching in private browser windows or without signed-in accounts; excluding it can eliminate up to 40% of viable search volume.

Frequently asked questions#
Can I exclude specific age groups from seeing my ads on Bing?
Yes, you can apply a -100% bid adjustment to specific age brackets (e.g., 18-24) to completely exclude them from ad delivery.
Why is the 'Unknown' demographic category so large?
'Unknown' includes users who are not logged into a Microsoft Account or who browse via private/incognito sessions where demographic data cannot be verified.
Should I exclude the 'Unknown' demographic segment?
No, excluding 'Unknown' typically results in a 30% to 50% drop in overall campaign volume and is generally not recommended.
How does demographic targeting interact with Smart Bidding?
Under Smart Bidding, demographic bid adjustments inform machine learning models as conversion probability signals rather than strict mathematical multipliers.
Does Google Ads allow age bid adjustments on Search campaigns?
Google allows demographic targeting on Search, but Microsoft's integration with signed-in Windows accounts provides unique desktop audience accuracy.
