The **Scripts** tab allows users to inject external scripts for a specific traffic source. These scripts will automatically be attached to any website page where the campaign’s **click script** is present — whether the page is built using Pingtree’s funnel builder or is an external website. ### Use Cases This feature is useful for: * Adding **Google Tag Manager** (GTM) scripts * Integrating **Meta/Facebook Pixels** * Installing third-party **tracking or analytics tools** * **Modifying the design and look** of the landing pages using custom CSS or JavaScript * Any other **external script injection** needed for tracking, analytics, or presentation customization Once configured, these scripts will be executed client-side, ensuring proper tracking and visual control per source.
