Finding your synced audience

Where an audience you synced from Primer shows up inside each ad platform.

Once an audience is Live, Primer has pushed it to the ad platform as a customer list / custom audience. It appears in that platform's own audience library, under the name it has in Primer. Use it in a campaign the same way you'd use any list you built there directly.

The exact menu names below are the ad platforms' own and can change — these are the areas to look in, not Primer screens.

It's Live in Primer but I don't see it yet

Live in Primer means Primer has pushed the list to the platform — the platform then takes its own time to build and match it before it appears and shows a size. That lag is normal and varies by destination (Microsoft, for instance, can take up to 48 hours). If the list still hasn't appeared well past the destination's matching time, check the connection and then why an audience won't sync. To push a filter change you made after syncing, use Rerun — until you do, the platform keeps the previously built version.

Google Ads

Open Tools → Shared library → Audience manager → Your data segments. The list appears as a Customer list. Newly synced lists show a processing state until Google finishes building them; see Google Ads for eligibility to serve.

Meta Ads

Open Audiences in Ads Manager (or Meta Business Suite). The list appears as a Custom Audience with source Customer list. See Meta Ads for the matched-size minimum before it can deliver.

LinkedIn Ads

In Campaign Manager, open Plan → Audiences (or the Matched audiences section when building a campaign). The list appears as a List upload audience.

Reddit Ads

In the Reddit Ads dashboard, open Audiences. The list appears as a Customer list custom audience.

DV360

In Display & Video 360, open Resources → Audiences → My audiences. The list appears as a first-party Customer Match audience on the partner/advertiser Primer synced to. See DV360 — it's a direct destination, not shared from Google Ads.

Microsoft Ads

In Microsoft Advertising, open Tools → Audiences. The list appears as a Customer List audience. You must accept Microsoft's Customer List terms before it will build — see Microsoft Ads.
