# Add Reporting Information to Your Tracking Links impact.com allows you to enhance the [tracking links](https://help.impact.com/partner/what-would-you-like-to-learn-about/platform-features/tracking/tracking-links/create-and-manage-links/create-tracking-links) you create by adding special parameters to promote your partnered brands. These query string parameters are added to the end of a tracking link URL to help organize information for effective analysis. This allows you to extract valuable insights during reporting, such as identifying your most traffic-generating promotional channels. Refer to the [Performance by Vanity Link](https://app.impact.com/secure/mediapartner/report/viewReport.report?handle=partner_perf_by_vlink) report for detailed insights into how your links are performing. {% hint style="danger" %} **Warning:** impact.com strongly recommends adding parameters on the impact.com platform rather than appending them manually. Altering your tracking links manually leaves room for error, which could prevent you from utilizing your reporting information effectively. When getting a tracking link from impact.com, you may see certain meta tags that a brand already added to the tracking link. These meta tags **must not be removed** as doing so will result in inaccurate tracking. {% endhint %} #### Add static parameters via the dashboard widget Use this method if you want to add parameters to a tracking link you generate for a specific brand program.

Dynamic parameters example {% hint style="success" icon="memo-circle-info" %} **Note:** The example below is for illustration purposes only. When setting up your own dynamic tracking, use the syntax and parameter values that are appropriate to your tracking setup. {% endhint %} Dynamic parameters are particularly useful for certain partner types, like Cashback and Loyalty websites, because they can help you ensure that members are correctly credited for clicks and actions. One use case for adding a dynamic parameter to your tracking link is to track which member in your site clicked on a link and purchased something. To track this dynamic value: 1. Add the text **{{MemberID}}** in one of your *Sub ID* fields. 2. Select **Save**. * This will generate a tracking link similar to the following: `https://acmecorp.sjv.io/c/111111/222222/33344?subId1=%257B%257BMemberID%257D%257D` * When a member of your website clicks on this link, your website will populate the *Sub ID* field with the member's actual ID (e.g., "12345678"), and this dynamically populated value will be reflected in impact.com reporting.

Warning: You can only add dynamic parameters to links on an ad card—it won't work with other link-creation methods. Ensure that your system is configured to accept dynamic variables. Work with your technical team or refer to your website provider's documentation for more information on how your website handles these types of variables.

#### Parameters reference & examples
SubId1, SubId2, & SubId3 The *SubId* parameter accepts a custom value that appears only in partner reporting (Advanced Action Listing, Performance by Sub ID). [Learn more about Sub ID values.](https://help.impact.com/partner/what-would-you-like-to-learn-about/platform-features/tracking/tracking-links/link-parameters/sub-id-and-shared-id-parameters-explained-for-partners) {% hint style="info" %} **Examples:** `https://le.pxf.io/c/1416144/674249/8882?subId1=blog` `https://le.pxf.io/c/1416144/674249/8882?subId2=blogarticle123` `https://le.pxf.io/c/1416144/674249/8882?subId3=instagrambio` {% endhint %}
SharedId The *SharedId* parameter accepts a custom value that appears both in partner reporting (Advanced Action Listing, Performance by Sub ID) and brand reporting. [Learn more about Shared ID values.](https://help.impact.com/partner/what-would-you-like-to-learn-about/platform-features/tracking/tracking-links/link-parameters/sub-id-and-shared-id-parameters-explained-for-partners) {% hint style="info" %} **Example:** `https://le.pxf.io/c/1416144/674249/8882?SharedId=partnerblog` {% endhint %}
u The *u* parameter is used for deep linking to a specific URL. The brand you're partnered with must also [allow deep linking](https://help.impact.com/partner/what-would-you-like-to-learn-about/platform-features/tracking/tracking-links/tracking-links-overview#before-you-begin-0-0), and the deep-linked URL must be a domain and path permitted by the brand. Keep in mind that the URL used must be percent-encoded (i.e., using valid [ASCII characters](https://www.w3schools.com/charsets/ref_html_ascii.asp)) ![](https://347878556-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2Fb2rE79d9UhOKZQLgzSqx%2Fuploads%2Fgit-blob-19030cdc586c42c2acb6fcf373f21925f0e089f1%2F43c928c1170f7294404de624b014d01b7f4a081cf6362a4833092870d77808d3.svg?alt=media). We recommend adding this parameter using one of the methods above if you're not comfortable manually encoding a URL. {% hint style="info" %} **Example:** `https://le.pxf.io/c/1416144/674249/8882?u=https%3A%2F%2Fexample.com%2Fstore%2Fproduct.html` {% endhint %}
TrafCat The *Traffic Category* parameter is a manually added custom value used primarily to label the category of traffic coming from a tracking link. Usually, this value is specified by the brand for you to use and used in context for where links are placed (e.g., "Toolbar" for traffic coming from a web toolbar). Brands can configure payout rules based on this parameter in the terms they propose to you. {% hint style="info" %} **Example:** `https://le.pxf.io/c/1416144/674249/8882?trafcat=toolbar` {% endhint %}
TrafSrc The *Traffic Source* parameter is a manually added custom value used primarily to identify the source from which traffic is coming. Usually, this value is specified by the brand for you to use and used to determine from where traffic is coming (e.g, "Paid Search"). Brands can configure payout rules based on this parameter in the terms they propose to you. {% hint style="info" %} **Example:** `https://le.pxf.io/c/1416144/674249/8882?trafsrc=paidsearch` {% endhint %}
ProdSku The *Product SKU* parameter is a manually appended custom value used to identify a brand's specific product SKU for tracking links that send traffic to a specific product. *Product Catalog* tracking links automatically add this value, but you can add this value manually if requested by the brand. {% hint style="info" %} **Example:** `https://le.pxf.io/c/1416144/674249/8882?prodsku=KS944RUR` {% endhint %}
Param1, Param2, Param3, & Param4 The *Param* parameter is a manually added custom value that works almost identically to the *SharedId* parameter. Brands may request that you pass values in these query strings, as they will appear in specific reports to brands, but not partners. {% hint style="info" %} **Examples:** `https://le.pxf.io/c/1416144/674249/8882?param1=ZveVDzsLSNLf` `https://le.pxf.io/c/1416144/674249/8882?param2=product100` `https://le.pxf.io/c/1416144/674249/8882?param3=desktop` `https://le.pxf.io/c/1416144/674249/8882?param4=somevalue` {% endhint %}
PartnerCustId The *Partner Customer ID* parameter represents the customer ID of the visitor in your system in the tracking link. This parameter can help impact.com track users across devices for more accurate attribution. {% hint style="info" %} **Example:** `https://le.pxf.io/c/1416144/674249/8882?partnercustid={partner_customer_id}` Where `{partner_customer_id}` is a unique value you assign to customers on your website. {% endhint %}
impacttest You can append the *impacttest* parameter to your tracking link when testing (to identify the click as a test click). {% hint style="info" %} **Example:** `https://le.pxf.io/c/1416144/674249/8882?impacttest=1` {% endhint %}
{% hint style="success" icon="memo-circle-info" %} **Note:** When getting a tracking link from impact.com, you may see certain meta tags that a brand already added to the tracking link. These meta tags **must not be removed**—doing so will result in inaccurate tracking. {% endhint %}
