3. Targeting: Finding Your Perfect Customer

Here's the truth about Facebook targeting: it's both easier and harder than it used to be. Easier because Facebook's algorithm is incredibly smart. Harder because iOS 14 privacy changes mean we have less data. But with the right strategy, you can still find your ideal customers.

Cold Audiences: Finding Strangers Who'll Buy

Cold audiences are people who've never heard of you. They're scrolling through Facebook, and suddenly your ad appears. Your job is to make them care enough to stop. Here's how to find them.

Interest-Based Targeting: The Smart Way

Think about your ideal customer. What do they like? What pages do they follow? What products do they buy? Facebook lets you target based on all of this. But here's where most people mess up: they either go too broad or too specific.

Too broad (targeting "Shopping" or "Fashion") and you're showing ads to everyone. Too specific (stacking 20 different interests) and your audience is too small for Facebook's algorithm to optimize.

The sweet spot? Combine 3-5 related interests. If you sell yoga mats, target people interested in yoga, meditation, and wellness brands like Lululemon or Alo Yoga. Keep your audience size between 500K and 5M for testing. Smaller than that and you'll struggle to get traction. Larger and you're too broad.

Pro move: Target your competitors' audiences. If you sell organic skincare, target people interested in brands like Drunk Elephant or The Ordinary. They're already buying what you're selling—just not from you yet.

Don't Overthink Demographics

Unless you have a very specific product (like maternity wear or men's grooming), don't get too narrow with demographics. Facebook's algorithm is smarter than your assumptions about who will buy. I've seen men buy products marketed to women and vice versa—as gifts, for partners, you name it.

That said, if your product has a clear demographic, use it. Just don't stack too many filters. Age range, location, and maybe gender. That's usually enough.

Warm Audiences: The Money Maker

This is where Facebook advertising gets really powerful. Warm audiences are people who already know you exist. They've visited your website, watched your videos, engaged with your posts. They're not strangers anymore—and that changes everything.

Website visitors are your foundation. Anyone who's been to your site in the last 30 days gets retargeted. These people are 5-10x more likely to buy than cold traffic. At minimum, show them your bestsellers and a compelling offer.

Add-to-cart abandoners are gold. They wanted to buy. Something stopped them—maybe price, maybe they got distracted. Hit them with a reminder, add some social proof, and watch the conversions roll in. These audiences convert at 10-15%, compared to 1-2% for cold traffic.

Checkout abandoners are even hotter. They made it all the way to checkout. They entered their information. Then something spooked them. A small discount or free shipping offer here can recover 15-20% of these lost sales.

Don't sleep on video viewers either. Someone who watched 75% of your video ad is interested. They might not have clicked, but they're warm. Create a special audience of these engaged viewers and market to them differently than cold traffic.

Lookalike Audiences: Your Cloning Machine

Lookalike audiences are Facebook's secret weapon. You give Facebook a list of your best customers, and it finds people who look just like them. Not demographically—behaviorally. It's spooky how well this works.

Start with a 1% lookalike of your purchasers. This means Facebook finds the 1% of people in your country most similar to people who've bought from you. These audiences perform incredibly well—often better than your own interest targeting.

As you scale, expand to 2-3% lookalikes. They're broader but still quality. Only go to 5-10% if you've truly exhausted everything else. At that point, you're basically targeting everyone, and the performance drops off.

Pro tip: Create lookalikes from your highest-value customers, not all customers. A lookalike of people who've spent $200+ will outperform a lookalike of everyone who's ever bought your $10 product. Quality over quantity.

4. Creating Ads That Actually Stop the Scroll

Let's talk about what really matters: creative. You can have perfect targeting and a huge budget, but if your ad looks like everyone else's, you're just burning money. After analyzing thousands of successful ecommerce ads, here's what actually works.

Image Ads: Your Foundation

Image ads are where most stores start, and for good reason—they're simple to create and test quickly. But the difference between a winning ad and one that gets ignored often comes down to a few crucial details.

Format matters more than you think. Go square (1:1) or vertical (4:5). Why? Facebook is a mobile-first platform, and these formats eat up more screen real estate. Horizontal images get lost in the feed, squeezed between posts from friends and family. Your ad needs to command attention, not blend in.

File size is a sneaky conversion killer. Keep images under 5MB. Anything larger and you're making mobile users wait while your ad loads. They won't. They'll scroll past before your beautiful creative even appears. Test your ads on a slower connection—if it takes more than a second to load, optimize it.

Here's something most beginners get wrong: they slap text all over their images. Facebook used to enforce a strict 20% text rule, and while that's relaxed now, the principle still holds. Let your image breathe. Show your product in action, being enjoyed by real people, not buried under sales copy. A lifestyle shot of someone genuinely loving your product beats a text-heavy graphic every time.

Colors are critical. Facebook's interface is white and blue. If your ad blends into that palette, it's invisible. Use bold, contrasting colors that pop in the feed—bright reds, deep greens, vibrant oranges. Whatever makes someone's thumb pause mid-scroll.

Video Ads: Where the Magic Happens

Video ads consistently outperform static images by 20-30%, but most people create them completely wrong. Here's the reality: you have 3 seconds. That's it. If your video doesn't hook someone in those first 3 seconds, they're gone.

Don't waste those precious seconds with logos, slow fades, or build-up. Start with the transformation. Start with the problem being solved. Start with someone speaking directly to camera. Make it impossible to ignore.

Keep it short. The sweet spot is 15-30 seconds. I've tested longer videos extensively, and engagement falls off a cliff after 30 seconds. People aren't watching Netflix on Facebook—they're scrolling. Get in, make your point, demonstrate value, and get out.

Here's a stat that should fundamentally change how you create video: 85% of people watch Facebook videos with the sound off. Read that again. If your video requires audio to make sense, you've already lost most of your audience. Add captions to every single video. Not optional. Required. And make sure those captions are baked into the video itself, not relying on Facebook's auto-caption feature.

For format, same rules apply: square or vertical. Horizontal videos create ugly black bars on mobile and cut your visual impact in half.

Video content that converts:

• Product demonstrations showing the transformation (before/after)
• Unboxing videos that showcase the experience
• Real customer testimonials (user-generated content crushes polished ads)
• Behind-the-scenes footage that builds connection
• Problem-solution format: "Tired of X? Here's Y"

Carousel Ads: Tell a Story

Carousel ads are criminally underused. They let you showcase 2-10 different images or videos in a single ad, and people can swipe through them. The beauty? Each card can link to a different product.

Use carousels to tell a story across the cards, show different product variations, or walk someone through a transformation. They work exceptionally well for collections or bundled products. Don't just slap random product shots in there—think about the narrative flow from card 1 to card 10.

Collection Ads: The Impulse Buy Machine

Collection ads are designed for one thing: impulse purchases. They show a cover image or video, with a grid of products below. Users can browse your catalog without ever leaving Facebook. It's frictionless shopping.

These work incredibly well for fashion, home decor, and beauty products—anything where people want to see multiple options quickly. The key is making that cover image or video so compelling they can't help but tap and explore.

5. Ad Copywriting

Ad Copy Structure

• Hook: Grab attention immediately (problem/benefit)
• Body: Explain benefits, social proof
• Offer: Discount, free shipping, guarantee
• CTA: Clear next step

Proven Copy Formulas

Problem-Agitate-Solution (PAS)

• State the problem
• Agitate the pain
• Present your product as solution

Before-After-Bridge

• Describe current frustrating state
• Paint picture of ideal outcome
• Show how your product bridges gap

Headlines

• Keep under 40 characters
• Lead with benefit, not feature
• Include offer if applicable
• Test multiple variations

Examples

• "Sleep Better Tonight" (benefit)
• "50% Off - Today Only" (offer + urgency)
• "As Seen On Shark Tank" (social proof)
• "1,000+ 5-Star Reviews" (social proof)

Call-to-Action Buttons

• Shop Now (most common for ecommerce)
• Learn More (for higher-priced items)
• Get Offer (for discount promotions)
• Sign Up (for email capture)

6. Budget and Bidding: Don't Waste Money Learning This the Hard Way

How Much Should You Actually Spend?

This is the question I get asked most: "How much should I spend on Facebook ads?" And like most things in marketing, the answer is: it depends. But let me give you practical numbers that actually work, not vague platitudes.

Testing phase: $10-20 per day per ad set. When you're starting out or testing new audiences and creatives, you don't need a massive budget. You need enough to gather data. At $10-20/day, you'll get enough clicks and impressions to know within 3-7 days whether something has potential or is a dud.

But here's the catch: if you're running conversion campaigns optimized for purchases, you need a higher minimum budget to give Facebook enough data to optimize. For conversion campaigns, aim for at least $50/day total. Why? Facebook's algorithm needs volume to learn. Below $50/day, the learning phase takes forever and you're burning money without meaningful optimization.

Scaling phase: increase 20-30% every 3-4 days. Found a winning ad set? Don't get greedy and double the budget overnight. That resets the algorithm's learning and often kills performance. The sweet spot is gradual increases—20-30% every 3-4 days. This keeps the algorithm stable while expanding your reach. Patience here pays off. I've seen countless advertisers destroy profitable campaigns by scaling too aggressively.

Retargeting: $5-15/day is usually enough. Retargeting audiences are smaller—you're showing ads to people who already visited your site. You don't need massive budgets here. In fact, overspending on retargeting usually means you're showing the same people your ads too many times, which tanks performance. Keep it modest.

Campaign Budget Optimization (CBO): Let Facebook Do the Work

CBO is Facebook's way of managing budget across multiple ad sets automatically. Instead of setting $20/day on five different ad sets, you set $100/day at the campaign level and let Facebook distribute it to whichever ad sets are performing best.

Here's why this matters: Facebook's algorithm is smarter than you at allocating budget in real-time. If Ad Set A is crushing it at 9am and Ad Set B performs better at 3pm, CBO automatically shifts money around. You'd never catch that manually.

CBO is recommended for most campaigns, especially if you're testing multiple audiences or creatives. The algorithm finds winners faster and stops wasting money on losers. The one exception: if you have a specific ad set you want to ensure gets budget (like retargeting), you can set ad set spending limits to guarantee it gets a minimum amount.

Without CBO, you're manually managing budgets across ad sets, which means winners might hit their budget cap while losers keep spending. CBO prevents this inefficiency.

Bidding Strategies: How Much to Pay for Results

Facebook offers several bidding strategies, and choosing the wrong one can cost you money or limit your reach. Here's what each actually does:

Lowest cost (the default): This tells Facebook to get you the most results at the lowest possible cost. The algorithm bids aggressively when it sees good opportunities and conservatively when competition is high. For most advertisers, especially beginners, this is the right choice. Let Facebook optimize—it's better at this than you are.

Cost cap: This sets a maximum average cost per result you're willing to pay. If your target CPA is $25, you set a cost cap at $25, and Facebook tries to keep your average CPA at or below that number. Use this when you have clear profitability targets and can't afford to go above a certain acquisition cost. The downside? Facebook might limit your delivery if it can't hit your cap, so set it realistically based on past performance.

Bid cap: This is advanced and most people should ignore it. Bid cap controls the maximum amount Facebook will bid in any individual auction. It's for experienced advertisers who understand Facebook's auction dynamics deeply. If you don't know exactly why you'd use this, stick with lowest cost.

The truth is, lowest cost works for 90% of advertisers. Facebook's machine learning is designed to optimize for this strategy. Only switch to cost cap or bid cap when you have specific constraints and enough data to know your target numbers are achievable.
