Tag Basics

Trusted Data Interchange (TDI) can manage tags that have visual components, such as widgets and ad trafficking scripts, as well as tags that collect data without any interaction with the end user, such as analytics, data management platforms, and the like.

Tag topics:


New tag

Creating tags

1. On the Dashboard, click New tag.

New tag

The New tag window is displayed. Required items are marked with an asterisk.

2. Type a unique name for the tag in the Name box.

If the tag is provided by a third-party vendor, we recommend using that vendor's name and the release date.


3. Optional: Type a description of the tag in the Description box. A description can help you identify this tag later.


4. Optional: If you're ready to start using this tag, change Fire in production to Enabled.

5. Optional: Type free-text categories to help organize your tags.


6. Click Create to create the tag and return to the Dashboard.


Testing tags

Type the anticipated deployment URL in the Default deployment URL box.

Default deployment URL

All tags are tested by TDI servers to analyze their data collection and cookie behaviors. By typing an anticipated deployment URL, the tag can be tested using actual user content.

The Mezzobit Visual Tagger also uses this URL to place tags on a page. For more information, see Visual components.

Typing a URL does not impact where the tag actually gets deployed, which is controlled by where the parent container is embedded. The URL is used only for testing purposes.


A/B testing

You can create two or more variants of a tag to see which version yields better results. For more information, see A/B testing.


Adding code to tags

Select the type of code to use for this tag from the Tag code list.

Tag code

Choose From library to browse partner templates that generate the necessary code for you.


Visual components

If your tag has a visual component, select Yes next to Is there a visual component and follow the on-screen instructions.

Is there a visual component

Use this option for tags that must be placed in a certain location on the page due to having a visual component such as a widget or ad module.

Tags can be placed only near page elements (div, ul, form, etc.) with unique IDs or in the beginning or end of the head or body sections. If a tag needs placement elsewhere, modify the target page to include a unique element ID.

For more information, see Using the Mezzobit Visual Tagger.


Scheduling tags

If this tag should be active for a limited amount of time, click Add period/schedule.

  • Use the calendar controls to pick a start date/time and end date/time for the tag.


  • If the active period for this tag is more complicated than a date/time range, use the Year, Month, Day, Day of week, Hour, and Minute controls to set up the tag's schedule. For example, if this tag should be active only on Thursdays, choose Thursday from the Day of week control.

Adding rules to tags

Add existing rules to the tag by selecting them from the Activation conditions list, or click Create rule to create a rule.

Activation conditions

For more information about rules, see Rule basics.



If this tag depends on other tags to be activated first, list the dependent tags in the Depends on box. This tag will not activate until the dependent tags are activated according to their rules.

Depends on


Delaying tag activation

By default, tags are activated immediately when all rules are met. To delay the activation of a tag, type a value in milliseconds in the Activation delay box.

Activation delay



By default, tags inherit time zone information from the parent container. Tags can also inherit time zone information from the user's browser.

If this tag relies on rules specific to a country or time zone, choose them from the Country and Time zone lists.
