How to Target Market on Facebook

Putting your brand in front of the right people on Facebook is the difference between a campaign that skyrockets your business and one that empties your wallet with nothing to show for it. Simply boosting a post and hoping for the best isn't a strategy. This guide breaks down exactly how to use Facebook’s powerful targeting tools to find the customers who are actively looking for what you sell.

The Foundation: Who Are You Actually Trying to Reach?

Before you ever open Facebook Ads Manager, you need a crystal-clear picture of your ideal customer. If your answer is "everyone," you’re setting yourself up for failure. A strong advertising campaign speaks to a specific person, not a faceless crowd. Take 15 minutes to sketch out a buyer persona.

Ask yourself these questions:

• Demographics: How old are they? Where do they live (city, state, country)? What’s their job title? Are they married? Do they have kids?
• Interests &, Hobbies: What do they do for fun? What brands do they love and follow on social media (competitors and non-competitors)? What books, magazines, or blogs do they read? Who are the influencers in their space?
• Pain Points: What problem are they trying to solve that your product or service fixes? What frustrates them about the current solutions available? What are their goals and aspirations?
• Online Behavior: Are they tech-savvy? Do they primarily use mobile or desktop? Are they active members of Facebook Groups? Do they shop online frequently?

Knowing this information moves you from vague targeting (like "women ages 25-45") to hyper-specific targeting (like "new moms ages 30-38 who live in Chicago, follow parenting blogs, and recently bought baby-related products online"). The better you know your customer persona, the easier the next steps will be.

Understanding the Three Pillars of Facebook Targeting

Facebook advertising is built on three main audience types: Core Audiences, Custom Audiences, and Lookalike Audiences. Once you understand how these three work together, you can create a full-funnel strategy that guides people from initial awareness all the way to becoming loyal customers.

1. Core Audiences: Finding New People from Scratch

This is where most beginners start. Core Audiences let you build an audience from the ground up by defining attributes based on demographics, interests, and behaviors. This is your tool for reaching people who have likely never heard of you before - your top-of-funnel audience.

How to Build a Core Audience:

Inside Facebook Ads Manager, at the ad set level, you’ll find the 'Audience' section. Here’s how to break it down:

• Location: Don't just target a whole country. You can target by state, DMA region, city, zip code, or even drop a pin and set a radius. This is perfect for local businesses or targeting specific high-value markets.
• Age &, Gender: Set these based on your customer persona. Don't guess.
• Detailed Targeting: This is where the magic happens. It’s split into three categories:
  • Demographics: This includes education level, life events (like an upcoming anniversary or being newly engaged), job titles, parental status, and more. For example, a roofer could target homeowners. A wedding photographer could target people who are 'Engaged'.
  • Interests: This is based on pages people have liked, content they engage with, and related topics Facebook's algorithm associates with them. Instead of broad interests like "fitness," get specific. Target followers of brands like Gymshark or Lululemon, magazines like Men's Health, or celebrity trainers like Kayla Itsines. The more specific, the better.
  • Behaviors: This powerful category is built from on-Facebook and off-Facebook user activity collected from data partners. You can target people based on their purchase behavior (e.g., 'Engaged Shoppers'), device usage ('Facebook access: iPhone 13'), or travel patterns ('Frequent Travelers').

Pro-Tip: Use "AND" Logic Through Layering

One of the biggest mistakes marketers make is lumping a dozen interests into one box. When you do that, you're telling Facebook to target people who like Interest A OR Interest B OR Interest C. This creates a very broad audience.

Instead, use the "Narrow Audience" option to create "AND" logic. This tells Facebook to target people who match your first criteria AND ALSO your second criteria. For instance:

• Broad Approach: Target people interested in Yoga, Lululemon, or Whole Foods.
• Narrowed Approach: Target people interested in Yoga AND ALSO in Lululemon. This person is far more likely to be a serious yoga enthusiast than someone who just likes one of those pages. You're layering interests to find your super-fans.

2. Custom Audiences: Reaching People Who Already Know You

A Custom Audience consists of people who have already interacted with your brand in some way. These are warm leads who are significantly more likely to convert than a cold audience. This is your tool for retargeting and nurturing relationships - your middle-of-funnel audience.

Creating Powerful Custom Audiences:

To create one, go to your 'Audiences' dashboard in Ads Manager. You’ll be able to create them from several sources:

• Customer List: You can upload a CSV file with customer information like email addresses and phone numbers. Facebook will match this data to user profiles, allowing you to target your existing customers with upsells, new product announcements, or reactivation campaigns.
• Website Visitors: This requires the Meta Pixel to be installed on your site. This is non-negotiable for serious advertisers. Once it's set up, you can create audiences of everyone who has visited your site in the past 180 days, or get more specific:
  • People who visited your pricing page.
  • People who added a specific product to their cart.
  • People who initiated checkout but didn't complete the purchase (a goldmine!).
  • People who spent the most time on your site.
• Facebook &, Instagram Engagement: Create audiences of people who have engaged with your professional accounts. This includes people who:
  • Liked your Page or followed your Instagram Profile.
  • Engaged with any post or ad (liked, commented, shared, saved).
  • Watched a percentage of one of your videos (creating an audience of people who watched 75% or more of a video is a great way to find engaged users).
  • Messaged your Page or Instagram account.

3. Lookalike Audiences: Scaling What Works

Once you’ve identified a high-value Custom Audience - like your best customers or a list of people who have completed a purchase - you can scale it with a Lookalike Audience. You give Facebook your 'source' audience, and their algorithm analyzes the common traits of the people within it. Then, it goes out and finds millions of new people who share those same characteristics.

How to Use Lookalike Audiences Effectively:

1. Start with a high-quality source audience. Garbage in, garbage out. The best source is often a list of your actual customers. A list of website visitors who made a purchase in the last 60 days is also excellent. The source audience needs to have at least 100 people from a single country for Facebook to work with it.
2. Choose an audience size. Facebook will ask you to select a percentage of the population in your target country, from 1% to 10%.
   • 1% Lookalike: This is a smaller, more concentrated audience that most closely matches your source. This is the best place to start. Their similarities to your customers are strong, so conversions are often higher.
   • 2-5% Lookalike: This is broader, giving you more people to reach but with slightly less relevance. Good for scaling a winning campaign.
   • 6-10% Lookalike: This offers massive reach but is much less similar to your source audience. Generally best for top-of-funnel awareness campaigns.
3. Always exclude your source audience. When you run an ad to a Lookalike Audience, be sure to exclude the original Custom Audience you built it from. There’s no point in paying to acquire a customer you already have!

Putting It All Together: A Simple Funnel Strategy

Now that you know the building blocks, here’s how they fit together in a real campaign for, say, an online coffee subscription brand.

• Top of Funnel (Awareness): Use a Core Audience to reach new people. You might layer interests like "Single-Origin Coffee" AND "Chemex" AND "Stumptown Coffee Roasters". The goal here is an introduction, run an educational video or engaging blog post ad.
• Middle of Funnel (Consideration): Build a Custom Audience of people who watched 50% or more of your video from the first campaign. Retarget them with a different ad, maybe one showcasing testimonials or explaining what makes your subscription unique. Also, target a Custom Audience of all website visitors who didn’t purchase.
• Bottom of Funnel (Conversion): Target people who added coffee to their cart but abandoned it with a direct offer - perhaps free shipping or a small discount - to get them over the finish line.
• Top of Funnel (Scaling): Once you have 500+ purchasers, create a 1% Lookalike Audience from your customer list to find thousands more people just like them, and start the funnel all over again.

Final Thoughts

Mastering Facebook's targeting tools allows you to move from guessing to strategy, ensuring your message reaches people who are predisposed to care about your brand. By systematically using Core audiences to find new customers, Custom audiences to nurture leads, and Lookalike audiences to scale, you can build a powerful and predictable engine for business growth.
