# Ads Sync

Ads Sync is Batch's **Paid Media** activation capability: it lets you activate your CRM segments as targeting audiences on paid advertising platforms, using the same segmentation engine you already use for your owned channels.

{% hint style="info" %}
Ads Sync is a paid offering available to customers on specific license tiers. It requires Solution Expert involvement for configuration. Contact your CSM to learn more.
{% endhint %}

### Keeping your ad audiences up to date

Ads Sync automatically shares a Batch segment with your advertising platform on a recurring schedule. Batch exports the segment, formats  it to match the destination platform's requirements, and updates the corresponding audience so it always reflects your latest targeting criteria.

Sync frequency is configurable. Daily and weekly schedules are the most common options.

### Supported destinations

Ads Sync currently supports Meta Ads, Google Ads, etc.

{% hint style="info" %}
Contact your CSM to get the latest updates on managed destinations.
{% endhint %}

Each segment synchronizes to a single destination platform. To activate the same segment on several platforms, set up a separate Ads Sync for each destination.

{% hint style="warning" %}
Ad networks apply their own matching delays and minimum audience size thresholds once Batch delivers a segment update. For reference, a synced audience can take up to 24 hours on Meta Ads and up to 48 hours on Google Ads to become available for targeting. Refer to each platform's documentation for current values.
{% endhint %}

### Use cases

* **Retargeting** — reach users who did not react to an email, push, or SMS campaign.
* **Suppression** — exclude users who already converted or engaged on an owned channel from your ad spend.
* **Lookalike seeding** — export a high-value segment to build a lookalike audience.
* **Dormant reactivation** — target users who have been inactive on owned channels for a defined period.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://doc.batch.com/getting-started/features/customer-engagement-platform/profiles/ads-sync.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
