Advertising Audience Sync. Your audiences, updated and synced to your ad platforms, automatically.
Build a segment of customers, profiles, orders or subscriptions in Metorik and sync it to Facebook and Google Ads as an audience. TikTok and Pinterest launching soon. No CSV uploads, no stale lists.
- Any Segment
- Syncs Automatically
- Hashed & Privacy-Safe
Any cohort you can imagine, as an audience.
Start from customers, orders or subscriptions, refine with 500+ filters – even across record types. Load a saved segment, or let Tori write the filters for you.
Made from all your store history, not the last 180 days of pixel fires:
- Bought product A but never product B, ever
- Subscription expires in the next 14 days
- 2+ orders, nothing in the last 90 days
The estimated audience size updates in real-time as you filter, so you know it clears the platform's minimum before you sync it.
Trusted by leading Shopify and WooCommerce stores:
Updated & Synced Automatically.
Whenever something changes on your store – updated orders, new customers, a failed subscription – Metorik re-runs the filters and syncs the difference to the ad platform.
Create exclusion audiences that actually exclude last week's buyers, or lookalike seeds that never go stale. Create a new audience, or sync into one another tool already feeds.
Audiences performance marketers build first, on any platform:
Exclude recent customers
Customers who purchased in the last 30/60/90 days, synced as an exclusion on every prospecting campaign.
Seed lookalikes from your top buyers
Top 10% by lifetime spend or anyone with 3+ orders, as the source for a lookalike, an Actalike or a Performance Max signal.
Win back lapsed customers
Last ordered 90+ days ago and no active subscription – retargeted with a compelling offer wherever they scroll.
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.
1 Audience. 4 Ad-platforms, each on its own terms.

Resync, pause, copy. Your audiences, your call.
Force a sync after a profile import. Pause an audience during a sale and resume it after. Duplicate or test two seeds against each other – set it up however you need.
Every sync is logged with added, removed, skipped and rejected counts, so when someone on your team asks why an audience changed size, the history has the answer.
Audience syncing live in three steps:
1. Connect the ad platform
Connect Facebook or Google Ads from Metorik's integrations and grant the audience permission. Already connected for ad cost reporting? It's one extra permission.
2. Build the audience
Pick the destination and a new or existing audience, choose customers, orders or subscriptions, add your filters and check the estimated size.
3. Create & start syncing
The first sync runs straight away and Metorik keeps it in sync every six hours after that. Included on every Metorik plan, with no add-on and no per-audience fee.
Advertising Audience Sync FAQs
Can't find what you're looking for below? Read our Help Docs
What is advertising audience sync?
Metorik's audience sync turns a segment of customers into an audience on your ad platforms and keeps the two in sync. Build a segment from customers, profiles, orders or subscriptions and Metorik syncs it to a Facebook Custom Audience or a Google Ads Customer Match list automatically.
Which ad platforms can Metorik sync audiences to?
Facebook and Instagram (as Meta Custom Audiences) and Google Ads (as Customer Match lists). TikTok Custom Audiences and Pinterest customer lists are launching soon.
Does it work for 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 sync customers or profiles from multiple stores, to one audience list.
How often does an audience sync?
Metorik keeps your audience in sync automatically, and you can manually trigger a refresh any time. The ad platforms take their own time to process an update – Facebook up to 24 hours, Google Ads up to 48 hours – so the audience shown in the ad platform can lag behind slightly.
Can I sync one segment to several ad platforms?
Yes. Create an audience per destination from the same filters, or build it once and duplicate to copy it to another platform. Each audience syncs on its own schedule and shows its own accepted, skipped and rejected counts.
What data leaves Metorik?
Only hashed identifiers, and only the ones the destination accepts. Facebook receives hashed email, phone, name, city, state, postcode, country and an external ID. Google Ads receives hashed email, phone and address. Every value is hashed with SHA-256 before it leaves Metorik, and the platform compares hashes against its own hashed user data to find matches – it never receives the plain-text values.
Can I sync into an audience that Klaviyo or a CSV upload already feeds?
Yes. Choose an existing audience or list when you create the sync. The first sync only adds people. From then on Metorik removes only the contacts it added itself, so anything Klaviyo, another app or a manual upload put there is left alone. There's also an Add only mode that never removes anyone, for all-time customer lists shared across stores.
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.
Does audience sync cost extra?
No. It's included on every Metorik plan with no add-on and no per-audience fee, for every supported ad platform. Create as many audiences as you need. Start a free 30-day trial to try it with your own store data.
