Meta Lookalike Audiences: The Complete Guide for Nepali Advertisers

When you first launch your Meta ad, you probably do a lot of research on how to target the right audiences. Maybe you watch YouTube tutorials, read blogs, or even ask someone who has run ads before.

Next, you might niche down your audience, add a filter based on your target audience's behavior, and launch the ad.

You feel relieved in the first week if you see potential results of your ad. But, weeks later, when people who see your ad don’t fulfil your ad objectives, they don’t really seem to be the right audience.

What nobody tells you, especially in tutorials that weren't made with Nepali advertisers in mind, is that defining your audience’s interest, behaviour, and demographics is just a guess. And guessing itself has a limit.

So, there’s also a way to show your ad to people who genuinely resemble your best customers, followers, or leads, without having to describe them at all. This feature is called a Lookalike Audience.

Instead of guessing which interests to target, you're letting Meta's algorithm do the task for you. You hand Meta a list of people who already bought from you, and ask it to find more like them.

For example, you have 500 of your best customers who know you well, they buy from you, trust you, and also come back.

Now imagine if Meta could scan its entire platform and find thousands of other people who behave, think, and act like those 500 customers, people who have never heard of you yet.

Instead of guessing which interests to target, you're letting Meta's algorithm do the task for you.

You hand Meta a list of people who are already your audience. Next, Meta studies their multiple patterns, like what they engage in, who they’re connected to, and their behavioural signals. Then it finds similar users who share the same patterns. Those people become your lookalike audience.

This process outperforms the manual interest targeting because the algorithm scans hundreds of patterns you are likely to miss.

A lookalike audience is only as good as the audience you build it from. Before starting, you need a source audience with at least 100 people.

But 100 is the bare minimum. Meta officially recommends that your source audience be between 1,000 and 5,000 people for the best results. The bigger and higher quality your source, the better your lookalike will perform.

There are multiple sources to choose from:

For most Nepali businesses starting, we'd recommend starting with your customer list or your top website visitors.

If you run a clothing brand and have 2,000 past buyers in your database, that's great. Upload that list, and let Meta find you 20,000 more people just like them.

If you don't have the required best data, you can use the second-best option to avoid building a broad list.

Let’s go through a step-by-step guide on how to create a Lookalike Audience:

Step 1: Go to Audiences in Meta Business Suite or Ads Manager

Step 2: Click Create Audience, then select Lookalike Audience

Step 3: Create a new source or select an existing one

Now, select the source of your custom audience.

Note: saved audiences cannot be used as a source

Step 4: Choose your audience size using the percentage slider

When you create a lookalike, it lets you choose a percentage from 1% to 10%.

The percentage is of Meta users in the target country who are most similar to your source (not the population).

• 1% lookalike = The most similar people to your source. Smaller audience, higher quality.
• 10% lookalike = Much broader audience, lower similarity to your source.

For Nepal, since the total active Facebook user base is smaller than markets like India or the US, even a 1% lookalike can give you a meaningful-sized audience to work with. If you need scale, let’s say for an awareness campaign across Nepal, you can go broader to 3%–5%.

Step 5: Click Create Audience

After creation, you’ll see one of three statuses:

• Populating: Meta is matching your audience to profiles. This can take up to 3 days. You can start running ads immediately, but the audience size will grow as it populates.
• Audience not created: Your source was too small. Try again with a larger list.
• Ready: Good to go. No need to wait for refresh cycles.

The lookalike audience works best when you understand the ad objective and the audience’s sources accordingly.

Awareness (Brand Building for Nepali Businesses)

When you’re launching a new product, opening a new branch in Birgunj or Biratnagar, or just want more people to know your brand exists.

How to use Lookalike Audiences here: Use a broader lookalike (3%–5%) when the goal isn’t the conversion but to maximize reach for brand awareness.

Traffic (Blog, YouTube, Landing Pages)

If you're a media company, a content creator, or driving people to a landing page, Traffic can be your objective.

How to use Lookalike Audiences here: Build a lookalike from people who spent the most time on your website, or from your newsletter subscribers. These are engaged, high-intent people, and their lookalikes will be too.

Sales / Conversions (For E-commerce & Product Sellers)

If you’re selling kurtas, electronics, handmade crafts, and skincare, then this is your objective.

How to use Lookalike Audiences here: Use your past purchasers as the source. The more data you give Meta, the better it performs. You're not just finding people like your customers, you're finding people like your best-spending customers.

Leads (Most Common for Nepali B2B & Services)

If you're a real estate agency, an education consultant, a financial advisor, or a software company in Nepal, the Leads objective is your best friend.

How to use Lookalike Audiences here: Build your lookalike from a list of your best past leads or converted clients. When Meta knows what your ideal lead looks like, their job, location, and behaviors, it will find similar people and show them your lead form ad.

Pro tip: If you've generated more than 20 leads using Meta technologies, you can also create lookalike audiences directly from the Leads Center in Meta Business Suite. So that you don’t need a separate custom audience setup.

App Promotion (For App Developers)

This ad objective is for tech startups and app developers in Nepal looking to promote their apps.

How to use Lookalike Audiences here: Build a lookalike from your existing app users.

Note: You'll need to be an app admin or developer to create this type of lookalike. Target people who look like your best users to drive installs.

Engagement (Grow Your Community)

When you want more page likes, more post reactions, and more video views, you can use engagement as your ad objective.

How to use Lookalike Audiences here: Create a lookalike from your most engaged followers, such as people who have commented, shared, or watched your videos. Then run engagement campaigns to people who look just like them. This builds a warm audience you can retarget later.

Meta Lookalike Audiences work because you've already done the hard part: building a customer base, collecting leads, and creating content that people engage with. The lookalike tool takes that evidence and multiplies it.

You don't need a massive budget. You need the right audience. A well-built 1% lookalike from 2,000 real customers will outperform a broad interest-based campaign almost every single time.

Start with what you have. Upload your customer list. Build your first lookalike. Test it against your current targeting.
