Seznam Retargeting is designed to reach users who visit your site.

## Tag Tips

* Use mappings to:
    * Dynamically override standard configuration values.
    * Dynamically override E-Commerce extension values.

## Tag Configuration

Go to the tag marketplace to add a new tag. For more information about how to add a tag, see [Manage tags](https://docs.tealium.com/manage-tags/).

When adding the tag, configure the following settings:

* **Rtg Id**: Your Seznam-supplied Merchant ID.
* **Auto Tracking**: Enable this option to call the `retargetingHit()` function every time the tag loads.

## Load Rules

Load the tag on all pages or set conditions for when your tag will load. For more information, see [About load rules](https://docs.tealium.com/about-load-rules/).

## Data Mappings

Mapping is the process of sending data from a data layer variable to the corresponding destination variable of the vendor tag. For more information, see [About data mappings](https://docs.tealium.com/about-data-mappings/).
