Facebook Ad Targeting Options and How Each One Works
On this page
Facebook ad targeting options are the settings that decide who can see your ads on Facebook, Instagram and Meta's other apps. You set them on each ad set: location, age, gender and language set the outer edge, detailed targeting adds interests and behaviours, and custom and lookalike audiences use your own data. Meta's automated audience options can widen delivery beyond what you choose. This explainer is part of our paid advertising guide.
It covers what each option uses, when it helps, and the limits Meta places on targeting.
Key takeaways
- Meta targeting is set on the ad set, not on keywords.
- Location, age, gender and language set the outer edge of an audience.
- Detailed targeting uses interests and behaviours; many sensitive options were removed.
- Custom audiences use your own data; lookalikes find people similar to them.
- Housing, employment and credit ads limit some audience options; social issue, election and political ads have their own authorization rules.
The targeting options at a glance
Meta's targeting choices fall into a handful of groups. Each one uses different information, and each one has its own trade-offs.
| Option | What it uses | Good for | Watch out for |
|---|---|---|---|
| Location | Countries, regions, cities, postal codes, radius | Matching your service area | Too small an area limits delivery |
| Age and gender | The ages and genders people give Meta | Products for a clear group | Tighter rules in special categories |
| Language | The languages people use on Meta | Ads not in the local language | Leave blank if it matches the area |
| Detailed targeting | Interests, behaviours, demographics | Reaching a defined niche | Options change; some were removed |
| Custom audiences | Your site visitors, lists, engagers | Retargeting and exclusions | Needs tracking and permission |
| Lookalike audiences | People similar to a custom audience | Finding new people like customers | Only as good as the source |
| Automated audience | Meta's delivery system | Broad prospecting | You give up some control |
Most ad sets combine a few of these. The skill is choosing the few that matter for your offer and leaving the rest open.
Location, age, gender and language
Location is the one setting nearly every business needs. Meta's API lets you include or exclude countries, regions, cities, postal codes and a radius around an address or point on the map. A local service business would usually choose its service area and exclude places it doesn't serve.
Age and gender narrow the audience to the people your offer suits. Use them when the product clearly fits one group, such as a service for retirees, and leave them broad when it doesn't. Every age band you exclude removes people who might still buy.
Language is easy to misuse. It targets the language people use on Meta, not where they live. Leave it blank when your ads are in the main language of the area, and use it when they aren't, such as Spanish-language ads in an English-speaking region.
If you need to reach people at one specific place for a short time, such as an event venue, a radius on Meta is one option. We explain how a dedicated fence works in how geofencing advertising works.
Detailed targeting: interests, behaviours and demographics
Detailed targeting is the group most people mean by Facebook targeting. It covers interests, such as an interest in home improvement, behaviours, based on actions people take, and demographic details, such as education or job field. Meta builds these from what people do on its apps and, in some cases, elsewhere.
The list isn't fixed. Meta announced in November 2021 that it would remove detailed targeting options relating to topics people may see as sensitive, such as health causes, race or ethnicity, religious practices, political beliefs and sexual orientation, from January 2022. Further removals and merges of rarely used or overly narrow options were reported from January 2024. Ad sets that used a removed option need new targeting.
When you add several interests, they generally work as alternatives: a person matching any one of them can see the ad. Requiring people to match two groups at once is a separate narrowing step. Stacking many interests usually widens an audience more than people expect.
Custom and lookalike audiences
Custom audiences are built from your own data. A website custom audience uses events from your Meta Pixel or Conversions API, such as people who visited your pricing page in the last few weeks. A customer list audience matches contacts you upload, after they're hashed. Engagement audiences include people who watched your videos, filled in a lead form or interacted with your page.
They do two jobs. You can target them, which is the basis of retargeting, or exclude them, such as keeping existing customers out of an ad for new customers. Both depend on tracking that works, which we cover in Meta Pixel and Conversions API setup.
Lookalike audiences start from one of your custom audiences, called the source, and find people in a chosen country who resemble it. A smaller lookalike sticks closer to the source; a larger one reaches more people with a looser match. The source matters most: a list of your best customers gives Meta a clearer pattern than a list of everyone who ever visited.
Automated audiences and how far to narrow
Meta increasingly asks advertisers to let its delivery system find the audience. Its automated audience option, called Advantage+ audience in Ads Manager, can treat the audience you describe as a starting suggestion and show ads to people beyond it when it predicts they'll respond. The API exposes this as a targeting automation setting on the ad set.
That changes how to think about narrowing. A tight audience gives you control but less room for Meta to learn. A broad audience gives Meta room but makes your creative do the targeting: the hook, image and offer decide who stops and responds.
A practical approach is to run one broad ad set, with location and any hard limits only, next to one built on your strongest custom audience or lookalike. Compare cost per result over the same dates. We explain how to keep ad sets few and clearly different in Meta ads campaign structure.
Limits that apply to every advertiser
Some limits apply whatever you choose. Ads about housing, employment or credit must be declared as a special ad category on the campaign. Those categories limit some audience options, such as age, gender and ZIP code, and location targeting has its own limits. Ads about social issues, elections or politics follow separate authorization and disclaimer rules. Check Meta's current rules before you plan, because they differ by category and region.
Targeting must also never be used to exclude people unfairly or to imply you know something sensitive about them. An ad that says "Struggling with your diagnosis?" reads as if you know the viewer's health, even when the targeting doesn't. Write the ad for the offer, not for a guess about the person.
Custom audiences bring their own duty: use only data you have permission to use, and describe ad tracking in your privacy policy. Once you know who you want to reach again, our guide to retargeting strategies explains how to match the message to what people did. If you'd rather have audiences planned, tested and refreshed for you, our in-house ads team runs Meta campaigns alongside the creative.
Common questions
What is the difference between a custom audience and a lookalike audience?
A custom audience is made of people you already have a connection with: site visitors, customers on a list you upload, or people who engaged with your page or videos. A lookalike audience is new people Meta finds who resemble a custom audience you choose as the source. Custom audiences suit retargeting; lookalikes suit finding new customers like your best ones.
How narrow should a Facebook ad audience be?
Narrow enough to exclude people who can't buy, such as those outside your service area, and no narrower. Each extra layer shrinks the pool Meta's delivery system can learn from, which can raise costs and slow learning. Start with location, a sensible age range and your offer, then test narrower options against that broad baseline before keeping them.
Why did some of my detailed targeting options disappear?
Meta removes and merges detailed targeting options from time to time. Some were removed because they related to sensitive topics, such as health, race or ethnicity, religion, political beliefs and sexual orientation. Others were reported as rarely used or overly narrow. Existing ad sets using a removed option usually need new targeting, so check Ads Manager for warnings after each change.
Can I upload my customer list to target ads on Facebook?
Yes, as a customer list custom audience, if you have the right to use that data for advertising. Meta matches the list to its users after the details are hashed, and you never see who matched. Only upload contacts who gave you their details with permission for this kind of use, describe it in your privacy policy, and keep the list up to date.
