Targeting is the choice of who your ads are shown to, based on traits such as location, age, interests or past behavior. In Meta ads, targeting is set at the ad set level, and it now works together with Meta's AI, which decides who in that group sees each ad.
Why targeting matters
Every impression costs money. If an ad reaches people who will never buy, you pay for attention that goes nowhere. If targeting is too tight, you pay more for each person because there are fewer of them. Good targeting finds a balance, putting the ad in front of enough of the right people for Meta to learn from the results.

| Approach | What you define | Best known for |
|---|---|---|
| Basic settings | Location, age and gender | Setting limits, such as a delivery area |
| Interests and behaviors | Topics people engage with and how they act | Reaching a niche when you know it well |
| Custom audience | People from your own data or Meta engagement | Retargeting and excluding customers |
| Lookalike audience | New people who resemble a source | Prospecting with a proven customer group |
| Broad targeting | Almost nothing beyond the basics | Letting creative and data steer delivery |
| Advantage+ audience | Suggestions that Meta can go beyond | Letting the AI find likely responders |
You can mix these. A common setup uses one ad set per approach, then compares them.
How targeting has changed
Years ago, the main skill in Meta ads was building precise audiences by hand. Now, Meta's AI chooses who sees an ad by predicting how likely each person is to take the action you asked for, so your goal, your conversion data and your creative carry more weight than they used to. Our answer on how Meta AI picks viewers for ads explains the signals involved.
That doesn't make targeting irrelevant. It moves it. You still decide who must be excluded, where you operate and which audiences are worth testing, but the fine work of finding people moves to the system. The better your tracking, the better the signal. Make sure the Meta Pixel and server events report your real conversions.
How to choose an approach
- Start from the goal. Selling to people who know you calls for custom audiences. Finding new customers calls for lookalike, broad or Advantage+ options.
- Look at your data. Accounts with plenty of conversions give the AI more to work with. New accounts may need tighter inputs at first.
- Set the limits that matter. Country, language and any legal restriction are worth setting, because the AI should never go outside them.
- Test, don't guess. Run two approaches with the same creative and budget as an A/B test, then judge by cost per result.
Common mistakes
- Stacking too many filters. Every extra layer cuts the audience, and a very small one is slow to learn.
- Targeting by assumption. A guess about your buyer is not data. Check who actually converts.
- Forgetting exclusions. Showing a new-customer offer to existing customers wastes spend.
Example. A language-learning app wants more paid sign-ups. It runs three ad sets with the same video and a $40 daily budget each: one on interests such as travel and languages, one on a lookalike of its paying users, and one on a broad audience limited to adults in the United States. After a week, each has spent $280. The interest ad set brings 7 sign-ups ($40 each), the lookalike brings 14 ($20 each) and the broad one brings 10 ($28 each). The lookalike gives the lowest cost, the broad audience the largest volume, and the interest audience the weakest results, so the app moves budget from interests to the other two.

FAQ
What is targeting in advertising?
It is the process of choosing which people see your ads, using traits like location, interests or past behavior. The aim is to reach people who are likely to respond and avoid paying for those who won't.
What are the types of targeting on Facebook?
The main types are basic settings such as location and age, interest and behavior targeting, custom audiences, lookalike audiences, broad targeting and Advantage+ audience. They can be mixed and tested against each other.
Is detailed targeting still worth using?
Sometimes. It can help in a niche you know well or when you have little data. Test it against broader options, because Meta's AI may reach the same people on its own.
How narrow should my targeting be?
Narrow enough to respect real limits, such as location, and broad enough for Meta to find people and learn. A tiny audience raises costs and runs out of fresh people fast.
Does the Meta Pixel affect targeting?
Yes. The pixel records what people do on your site, which feeds website custom audiences and gives Meta's AI the signals it uses to find likely buyers.
