Learn about traffic sources called sub-IDs and how to optimize them for better performance.

The traffic RTX Platform delivers to your Pops campaigns comes from many different sources. Each source is represented by a unique code called a sub-ID. You can track sub-ID performance, then use blacklisting to customize which sub-IDs you'd like to receive traffic from.

RTX Platform works with many different channel partners to deliver traffic to your Pops campaigns. Channels can consist of several different traffic sources, which are called sub-IDs.
​
Performance can vary by channel and sub-ID. Channels affect how your ad is served, so users may see ads more frequently on certain channels than on other channels. Sub-IDs represent the type of traffic. For example, some sub-IDs may serve your ads on URL-shortened links, like bit.ly.

Install a conversion pixel to track conversion rates and profit for each sub-ID in RTX Platform's comprehensive reporting suite, or append the {subid} macro to your creative URLs to pass sub-ID data to your tracking platform.

Once you've collected enough sub-ID data, you can identify the low-converting sub-IDs and add them as blacklisted sub-IDs to prevent your campaign(s) from receiving traffic from those sub-IDs.

TIP: Increase conversions with Blackballer! Blackballer intelligently pauses any channels and blacklists any sub-IDs and domains that have not received conversions after sufficient testing. Enable Blackballer on your campaign’s Settings page. Learn more.
