Age targeting in Google Ads focuses your budget on the people most likely to buy. It's one of the fastest ways to cut wasted spend and lift campaign performance.
Why Target by Age on Google Ads
Reaching the right demographic beats reaching everyone. Age targeting helps you spend where it actually matters.
Reach your ideal customer demographic
Every product has a core buyer. Age targeting aligns your ads with who that buyer actually is. A retirement planning service has a very different audience than a gaming app.
Optimize budget for better ROI
Concentrating spend on high-converting age groups improves return on ad spend. You stop paying for impressions that rarely turn into customers.
Reduce wasted spend on irrelevant audiences
Age exclusions are as powerful as inclusions. If an age group consistently doesn't convert, pull back your bids or exclude it entirely. Every dollar saved on poor-fit audiences is a dollar freed for what works.
Age Targeting Options Available in Google Ads
Google gives you seven predefined age ranges and one catch-all category to work with.
The seven age ranges Google offers
Per Google's Ads Help Center, the available age ranges are 18-24, 25-34, 35-44, 45-54, 55-64, 65+, and Unknown. These are fixed. You cannot create custom ranges.
How Google determines user age
Google pulls age data from user Google Account preferences, website activity, and estimated patterns across Google properties and the Display Network. The signal isn't perfect, but it's directionally useful at scale.
Understanding the 'Unknown' category
Many users don't log in or share demographic data. Those users land in the Unknown bucket. It's selected by default for good reason. Excluding it can cut your reach significantly and filter out real buyers.
Which campaign types support age targeting
Age targeting works across Search, Display, Video, Demand Gen, and Gmail campaigns. You can apply it at the campaign level or the ad group level.
How to Set Up Age Targeting in Google Ads
The setup takes under five minutes once you know where to look.
Step 1: Navigate to Demographics in Google Ads
Open Google Ads. Go to Campaigns and select Audiences from the left menu. Click the Demographics tab.
Step 2: Select your age ranges
Click the Age tab. Check the specific ranges you want to include or exclude. You can target multiple ranges at once.
Step 3: Save your targeting choices
Click Save Demographics. Changes apply immediately to that ad group or campaign.
Using Google Ads Editor for bulk updates
Per the Google Ads Editor Help Center, select an ad group, go to Keywords and Targeting, then Ages, and click Add age. Pick a range from the dropdown. You can also set bid adjustments here in bulk across multiple ad groups at once.
Optimizing with Bid Adjustments by Age
Bid adjustments let you compete harder for ages that convert and pull back on the rest.
Understanding bid adjustment ranges (-90% to +900%)
Per Google's documentation on bid adjustments, you can increase or decrease bids for any age demographic from -90% to +900%. That's a wide range. Use it deliberately.
Bidding more aggressively for high-performing age groups
If the 35-44 segment converts at twice the rate of others, raise their bid adjustment. You'll win more auctions for that segment without inflating costs across the board.
Bidding down or excluding low-performing ages
A -90% adjustment effectively suppresses a segment without a hard exclusion. A hard exclusion removes them entirely. Let your conversion data guide which approach fits each segment.
Testing and refining based on performance data
Don't set adjustments and walk away. Pull age segment reports after two to four weeks of data. Adjust based on actual conversion rates, not assumptions.
Best Practices for Age Targeting
These habits separate campaigns that scale from ones that stall.
Don't exclude 'Unknown' unless absolutely necessary
Unknown traffic often represents a large portion of real buyers. Excluding it without supporting data is risky. Test performance first before cutting the segment from your campaigns.
Combine age targeting with other targeting methods
Age alone is rarely enough. Layer in household income, interests, or in-market audiences. Stacking demographic signals tightens your targeting without shrinking reach too aggressively.
Monitor performance by age segment regularly
Pull demographic reports at least once a month. Age performance shifts over time. A segment that underperformed last quarter may improve after a creative refresh or offer change.
Use data-driven bid adjustments
Base bid changes on conversion data, not intuition. Start with small adjustments. Scale up once a trend holds across several weeks of consistent data.

Frequently Asked Questions
Can you target users under 18 on Google Ads?
No. Per Google's policy, the youngest selectable age range is 18-24. Google Ads does not allow targeting children under 13 at all, even if they have a Google Account created via Family Link.
What is the Unknown age category in Google Ads?
Unknown includes users whose age Google cannot determine because they haven't shared demographic data through their Google Account. Excluding this category can significantly reduce your reach, so keep it active unless your conversion data justifies removing it.
Do bid adjustments for age work on all campaign types?
Bid adjustments for age demographics are available for Search, Display, Video, and Demand Gen campaigns. You can set them at both the campaign level and the ad group level for flexible control.
