The problem

Why your ad audiences are ineffective

Time-consuming, outdated manual CSV exports

To create Custom Audiences on Meta Ads or Google Ads, you have to manually export your customer list from your CMS, format it correctly, then import it into each ad platform. By the time you finish, the data is already stale. A customer who ordered this morning will not appear in your audience until the next export, sometimes weeks later.

Static audiences that do not reflect reality

Manually created audiences are snapshots frozen in time. A customer classified as active 3 months ago may have become inactive today, but they remain in your retargeting audience. Conversely, a new loyal customer is not yet in your VIP audiences. Your campaigns target an outdated version of your customer base, wasting your ad budget.

No targeting based on real customer value

Your ad audiences are typically based on simple criteria: all buyers, recent buyers, or a raw email list. It is impossible to create an audience of your RFM champions, high-LTV customers or customers at risk of churning. Without behavioral segmentation in your ad platforms, you cannot differentiate your investments by customer value.

The solution

How Fullmetrix automates your ad audiences

Automatic and continuous sync

Connect your Meta Ads, Google Ads and TikTok Ads accounts in a few clicks. Fullmetrix automatically syncs your customer segments to each platform as Custom Audiences. Audiences are continuously updated: every new customer, every segment change is automatically reflected in your ad platforms.

Real-time segments based on behavior

Audiences are not based on static lists but on RFM and lifecycle segments calculated in real time by Fullmetrix. When a customer moves from the active segment to the at-risk segment, they are automatically removed from the active audience and added to the retention audience. Your campaigns always reflect the current state of your customer base.

Multi-platform from a single place

Manage your Meta Ads, Google Ads and TikTok Ads audiences from a single interface. Create a segment once and push it to all your platforms simultaneously. Compare segment performance across platforms to identify where your ad budget is best invested.

Is my customer data transmitted in plain text?+

No. All data is hashed in SHA-256 server-side before being transmitted to ad platforms. This is the standard required by Meta, Google and TikTok. No personal data in plain text leaves Fullmetrix.

Can I choose which segments to sync?+
