What Metorik's Facebook Audience Sync does…
Metorik allows you to turn any group of customers into a Facebook Custom Audience and it keeps it up to date, and in sync, automatically. Use the audience in Ads Manager for retargeting, as an exclusion, or as a Lookalike Audience.
1. Create your segment
Start from customers, profile, orders or subscriptions and refine with 500+ filters. The estimated audience size updates as you go.
2. Hashed and synced
Metorik hashes every identifier with SHA-256 and creates the Custom Audience in Facebook , or syncs into one you already have.
3. Updates and resyncs
People who now match are added, people who don't are removed (or optionally never removed). Pause, duplicate or force a sync any time.
The full story, with the audience builder and sync controls in detail: Advertising audience sync
Create a new Custom Audience, or feed an existing one.
Metorik creates a customer-list Custom Audience named after your segment. Or choose an existing list and Metorik will sync contacts in, and only remove those it added, so a CSV or Klaviyo feed keeps working.
Lifetime spend synced automatically. Every Custom Audience Metorik creates carries each customer's lifetime value, so it can seed a value-based Lookalike Audience weighted towards your best customers.
Audiences Facebook media buyers build first:
Exclude recent customers
Customers who purchased in the last 30/60/90 days, synced as an exclusion on every prospecting and Advantage+ campaign.
Seed lookalikes from your top buyers
Top 10% by lifetime spend or anyone with 3+ orders, synced with LTV as the source for a value-based Lookalike Audience.
Win back lapsed customers
Last ordered 90+ days ago and no active subscription – retargeted on Facebook and Instagram with a compelling offer.
Cross-sell by popular combination
Bought product A, never bought product B, shown creative for B. Or subscriptions renewing in 14 days, shown the upgrade path.
Facebook audience syncing live in three steps:
1. Connect Facebook
Connect your Facebook ad account and grant the Ads Management permission. Already connected for ad costs? It's one extra permission.
2. Build the audience
Choose a new or existing audience from Facebook, then select customers, orders or subscriptions, add your filters and check the estimated audience size.
3. Create & start syncing
The first sync runs straight away, then Metorik keeps it in sync automatically. Facebook audience sync is included on every Metorik plan, no additional costs.
Facebook Audience Sync FAQs

What is Facebook audience sync?
Metorik's audience sync turns a segment of customers into a Facebook Custom Audience and keeps the two in sync. Build a segment from customers, profiles, orders or subscriptions and Metorik syncs it to Facebook automatically.
What's the minimum audience size?
Facebook says they need at least 100 matched people before an audience can be used for ads, and recommends 1,000 or more as the source for a lookalike audience. Metorik shows an audience size estimate live while you build the segment, so you can widen the filters before you sync if the audience is too small.
What data is sent to Facebook?
Only hashed identifiers: email, phone, name, city, state, postcode, country and an external ID. Every value is hashed with SHA-256 before it leaves Metorik, and Facebook compares hashes against its own hashed user data to find matches – it never receives the plain-text values.
Is this the same as Shopify Audiences?
No. Shopify Audiences is Shopify's own product, available to Shopify Plus stores in certain regions, that builds prospecting audiences from data pooled across participating Shopify merchants.
Can I build value-based lookalikes from a synced audience?
Yes. When Metorik creates a Facebook Custom Audience it includes each customer's lifetime spend, so you can pick the audience as the source for a value-based Lookalike Audience and let Facebook weight the seed towards your highest-value customers. The value refreshes with every sync.
Does it work for both WooCommerce and Shopify stores?
Absolutely. Connect your WooCommerce or Shopify store to Metorik and every customer, order and subscription is available to filter. You can even feed one audience from multiple stores.
