How to Use Lookalike Audiences

Lookalike audiences are one of the easiest ways to scale results once you already have some good data like website visitors, leads, or customers. Instead of guessing who might be interested, you tell the platform: “Find me more people like these ones.”

Benefits Of Using Lookalike Audiences

This is widely used in social ads, but it works best when your foundations are strong clean tracking, clear targeting, and a landing page that converts. If you’re running campaigns with a social media agency or doing it in-house, this guide will help you use lookalikes properly (and avoid the common mistakes that waste budget).

What is a lookalike audience?

A lookalike audience is built from a source list (also called a seed audience). The platform studies patterns from your source like behaviours, interests, demographics, and engagement and then finds new people who are similar.

In simple terms:

• Source audience = people you already know are good

• Lookalike audience = new people who resemble them

This is especially useful for brands in competitive spaces where broad targeting gets expensive, and you want your spend to work harder whether you’re running social media marketing or broader digital marketing singapore campaigns.

What makes a strong lookalike source?

Your results depend heavily on the quality of your source. The platform can only “copy” what you feed it.

Best sources

1. Purchasers / qualified leads (highest quality)

2. People who completed key actions (booked a call, submitted a form)

3. High-intent site visitors (pricing page, checkout page)

4. Video viewers or engaged social users (good for awareness, weaker for sales)

If you want lookalikes to drive real enquiries, you need clean conversion tracking. That’s where many businesses benefit from proper setup and auditing especially when combining Meta with pay per click singapore campaigns for full-funnel coverage.

Step-by-step: How to set up lookalike audiences

Step 1: Choose your goal first

Before you create anything, decide what you want:

• Leads

• Sales

• Website traffic

• Video views

If your goal is leads, build your lookalike from people who already became leads not just followers or random visitors.

If you need help mapping this out across channels, a good marketing agency will plan the full funnel so your audiences match your objective.

Step 2: Build the right source audience

Here are common seed options:

• Website actions (form submit, purchase, add to cart)

• Customer list (email/phone list)

• Instagram engagement (people who interacted with your profile)

• Video views (people who watched 50%+)

If your business is still growing and you don’t have many conversions yet, you can start with:

• People who visited high-intent pages

• People who messaged your page

• People who engaged with your posts

But as soon as you have enough conversions, upgrade your seed to “best quality” events.

Step 3: Pick the right lookalike size

Most platforms let you choose how “close” the match should be.

• 1% lookalike = closest match, usually best for performance

• 2–3% = broader reach, often works after 1% is stable

• 5–10% = very broad, usually better for awareness

A simple approach:

• Start with 1%

• Once you’re seeing consistent results, test 2% and 3%

• Only go broader if you’ve already tested creatives and your funnel converts

Step 4: Use the right structure in your ad account

Lookalikes can be used in different ways depending on what you run.

Option A: One lookalike per ad setThis keeps performance clean and easy to understand.

Option B: Stack lookalikes (carefully)Stacking means adding multiple lookalikes into one ad set. This can work, but it makes reporting less clear.

If you want a clean structure and reporting that makes sense, this is where a professional setup helps especially if your business also runs Google campaigns like google-search-ads and wants consistent performance tracking.

How to make lookalikes work better

1) Exclude existing customers and leads

If your goal is new sales or new leads, exclude:

• Existing customers

• Existing leads

• People who already converted

This avoids paying for the same people again.

2) Match your creatives to your audience stage

Lookalike audiences are “new” people. They usually need:

• Clear offer

• Simple benefits

• Proof (reviews, results, examples)

That’s why creative testing matters so much. Many brands underestimate this and blame the audience when it’s actually the ad content. If you’re producing new creatives regularly, pairing lookalikes with strong content creation helps especially with monthly-content-creation.

3) Don’t ignore landing pages

A strong lookalike audience will still fail if the landing page is confusing, slow, or unclear.

If your site needs improvements for conversion and trust, your overall digital marketing services in singapore strategy should include both ads and on-site optimisation because traffic without conversion is wasted spend.

4) Refresh lookalikes when your business changes

If your product pricing changes, your offer changes, or your audience shifts, refresh your source audience. Lookalikes are only as accurate as the “best customers” you feed into them.

Common mistakes to avoid

• Using followers as a seed when your goal is leads (often too weak)

• Going too broad too quickly (jumping to 5–10% early)

• Running lookalikes without proper tracking

• Testing audiences but never testing creatives

• Forgetting exclusions and paying to target existing customers

If you want consistent performance, treat lookalikes as one part of a bigger system ads + creative + tracking + landing page.

When lookalikes aren’t the best option

Sometimes lookalikes underperform because:

• You don’t have enough conversion data yet

• Your conversion event is not clean (wrong event, wrong tracking)

• Your offer is unclear

In that case, it may be better to run broader targeting with strong creatives while you build data then switch to lookalikes once you have enough high-quality events.
