How to create a custom audience on Facebook

A custom audience is a group of people you already have a connection with, built from your own data or from engagement on Meta's apps. You use it to show ads to them (retargeting) or to leave them out, and you can use it as the source for a lookalike audience.

The quickest audience for most Pages. Meta's steps:

1. Open Audiences in Ads Manager.
2. Select Create audience, then Custom audience (or Create a custom audience if it's your first).
3. Select Facebook Page, then Next.
4. Choose your Page and the events. The default is everyone who engaged with your Page.
5. Set audience retention in days. The value must be 365 days or less.
6. Optionally add up to four more criteria with Include more people or Exclude people.
7. Add a name and description, then select Create audience.

You need to own the ad account or have admin or advertiser permissions, and it must be connected to a business portfolio. Meta notes new accounts may wait a few weeks before they can create one, and you need a legal basis to use the data.

1. Open Audiences, select Create audience, then Custom audience.
2. Select Customer list, then Next, and format your list as instructed.
3. Choose Inclusions or exclusions, or Only exclusions (which can't be changed later or used for a lookalike).
4. Upload a file or paste comma-separated values, add a name and accept the terms.
5. Check the mapped identifiers, fix any marked with an exclamation mark, then select Import and create.

First make sure your Meta pixel is active. Then:

1. Open Audiences, select Create audience, then Custom audience, then Website.
2. Choose your pixel as the source and pick the events, such as visitors to specific pages.
3. Set the audience retention in days and add up to five rules in total.
4. Name the audience and click Create audience. Meta says it starts filling from the day you create it and doesn't backfill.

Meta's explanations and fixes:

• Still populating: wait until Status shows Ready on the Audiences page before using it.
• Fewer people than visits: only people with Meta accounts count, each person once, and people who opted out of online behavioural advertising are left out.
• Too small to use: Meta suggests waiting for several hundred people, using fewer conditions or a longer window.
• Outdated: a customer list not updated in over 30 days shows Outdated, which may affect delivery. Choose Update list.
• Low match score: add more emails, phone numbers and device IDs to improve the score out of ten.

Zolyp is our product, so weigh this section with that in mind. A Page engagement audience is only as big as the engagement behind it. Zolyp keeps your Page posting every week, so there are people to retarget when you're ready to run ads; it doesn't build audiences or run ads itself.

Zolyp plans the week across your content themes, writes the captions and designs the visuals against your Brand Brain (your tone, colours and rules, saved once), then schedules and publishes to Instagram, Facebook, LinkedIn, Google Business, X, TikTok, YouTube, Pinterest, and Threads. You review and approve the week, and Autopilot lets you hand off publishing theme by theme once you trust the output. Plans that create the posts start at $29 a month, with a 3-day free trial and no card required.
