Tracking Link Terms and Concepts

What is a tracking link?

When a user views or clicks on one of your ads, they are activating a link that notifies your attribution provider of the view or click. The attribution provider uses this information to track mobile app installs and re-engagements. The link can include other information, which will eventually be displayed in your reports.

What are Singular Links?

Singular Links are Singular’s new tracking link solution. Marketers can create and manage their Singular Links through an intuitive UI that walks the user through all the available options for link behavior, attribution settings, and additional information to include in the link.

Singular Links automatically leverage iOS Universal Links and Android intent technology to create deeplinks whenever possible (see the Prerequisites).

Here is an example of a Singular Link - you can try it out on your iOS or Android device:

Note on legacy tracking links: In the documentation, we use the terms “Singular Links” and “tracking links” interchangeably. Your account may still have access to Singular’s legacy tracking link solution. To avoid confusion, these will be referenced as “legacy tracking links”.

What is a deeplink?

Deeplinks are links that not only open the app on the user’s device (if the user already has the app installed) but also show specific app content or a specific user experience instead of just opening the app’s default screen. Learn more in our Deeplinking FAQ.

What is a redirect?

When a user clicks a regular link on the web, such as, the browser asks the URL’s server (in this case, LinkedIn) what it should do, and in return the URL’s server gives the browser some HTML to display to the user.

When a user clicks a tracking link, the link provider’s server tell the user’s browser to go to a different URL instead (the redirect URL), and to serve the content from that URL. The redirection is usually performed via HTTP 302.

What is a fallback redirect?

In the context of deeplinking, a fallback redirect is a redirect destination that you want to take the user to in case the deeplink fails.

Typically, if a user clicks an ad for your app, you want the deeplink to send them into a specific screen inside the app. But if the user doesn’t already have the app installed, you want to redirect the user to the app store instead, so they can download your app.

Creating Singular Links

What is a Link Sub-Domain?

Singular tracking links have the following structure, where [SUB-DOMAIN] is chosen by you:


For example, for a campaign that markets an app called Jewel Rush, you can create the sub-domain “jewelrush”. Then you can use it to create tracking links with the following structure:[PARAMETERS]

You can create a single sub-domain and use it for all your links, or you can create several to use for different purposes. You have to create at least one sub-domain.


What is the Link Type? What is the difference between Partner links and Custom Source links?

Partners are services that are integrated with Singular’s attribution service.

When you create a Partner link, Singular automates the process by:

  • Displaying only the options that are supported by that partner. For example, some partners support only iOS or only Android.
  • Generating the tracking link with partner macros that allow the partner to pass campaign information to Singular.

Custom Sources are self-owned or self-managed marketing channels such as email or SMS campaigns, social media, and cross-promotion campaigns.

Note: If you are working with an email service provider, create a Partner tracking link. If you manage your own email campaigns, create a Custom tracking link..

Why isn’t Facebook/Twitter in the Source Name dropdown?

Self-Attributing Networks such as Facebook and Twitter do not use Singular tracking links. To configure them, see Attribution Integrations: Special Instructions.

What is the "Tracking Link Name"?


This is just a name you give your tracking link, and it can be whatever you want (although most users use the campaign name or a variation of the campaign name).

The Tracking Link Name will appear in your reports as “Tracker Name”.

Can I use the same tracking link for iOS and Android?

You can sometimes - depending on the partner.

  • Some partners support only iOS or only Android.
  • Others support both platforms, but require you to create a separate link for each.
  • Finally, some partners allow you to create multi-platform links, where you create one tracking link for use with both platforms.

The Create Link page displays the options that are supported by the partner you have selected.

Note: To make your link available for a certain platform, you first have to set up your app for that platform (add an app site) in Singular's Apps Configuration page.

See our Best Practices and Examples article for more information.

What is re-engagement?

Re-engagement means targeting existing users. Not all partners support this type of marketing campaign. If a partner does support the option and you want to use this Singular Link to track re-engagement as well as new installs, select Enable Re-engagement Tracking.

Why is “Enable Re-engagement” not available for a partner?

Some partners do not support re-engagement campaigns. If a partner does support re-engagement but the option is not available in Singular’s Create Link/Edit Link page, please contact Singular’s support team so we can update the integration.


What’s the difference between “deterministic” and “fingerprinted” clicks/views?

Deterministic clicks/views are those that are attributed to a source based on a device identifier or Google Install Referrer.

Fingerprinted clicks/views are attributed based on device fingerprinting methods, i.e. a combination of various properties that Singular gathers about the user’s device at the absence of a device ID.

See Device Fingerprinting Methodology for more information.

Why doesn't the page let me create a link?

Check if the link exists already. You cannot create a tracking link with the same source, tracking link name, and configured app site(s) as an already existing link.

Link Structure and Parameters

What do the different parts of a Singular Link mean?

This is an example of a Singular Link generated in the Create Link page:{idfa}&aifa={aifa}&pcn={campaign_name}&pcid={campaign_id}&pcrn={creative_name}&pcrid={creative_id}

The components of the link are:

Component Example Description
Subdomain nike The customizable subdomain of the tracking link.
Domain The domain of the tracking link.
App ID (Path) C59c0 A Singular-generated ID representing the app. Used in conjunction with the Link ID to uniquely identify the tracking link.
Link ID (Path) 47bm A Singular-generated ID representing the link information encoded in the tracking link. Used in conjunction with the App ID to uniquely identify the tracking link.
Query Parameters _dl=singular%3A%2F%2Ftestlink
Optional parameters that add functionality and reporting granularity to the tracking link.
What query parameters can I use in a Singular Link?

See Tracking Link Parameters and Report Dimensions for the full list of query parameters.

Editing and Archiving Links

What happens if I edit a tracking link that is already being used?

The changes take effect as soon as you click Save in the Edit Tracking Link page.

If the link is already active in campaigns, any past clicks, impressions, and attributions belonging to these campaigns are not affected.

Note: We do not recommend editing live tracking links. The editing functionality is provided for adjusting settings or correcting mistakes in the campaign preparation stage. Editing a link after it’s live may have unintended effects on attribution.

What happens to a link when I archive it?

When you archive a tracking link, that link is hidden from your tracking link dashboard. The purpose is to declutter your dashboard by hiding old links that belong to past campaigns.

Archiving does not deactivate a link. If you archive a link that is still being used in a live campaign, the link will still redirect and attribute users.

Note: Archiving is not reversible!
