    • Backup Link

    Comprehensive protection to keep your ad delivery links running smoothly, preventing traffic loss caused by domain bans, DNS resolution failures, domain expiration, and more.

    Step 1 - Find the Domain You Want to Configure in the Domain List, Click the "Configure" Button, and a Configuration Panel Will Appear on the Right

    Two backup link strategies are currently supported: redirect to a custom URL, and guide the user to copy a new link for installation.

    Strategy 1: Redirect to a Custom URL

    When this strategy is selected, users will be automatically redirected to the URL you specify if the domain is banned. Note: PWA links are not supported here!

    Steps:

    • Select Redirect to a Custom URL in the configuration panel
    • Enter a backup URL (e.g., https://roibest.com)
    • Click Save to complete the configuration

    When the domain is banned, users will see a landing page containing a PWA promotion link on a different domain. They can copy the link and open it in Chrome to reinstall.

    Steps:

    • Select Guide the User to Copy a New Link for Installation in the configuration panel
    • Choose a promotion link that uses a different domain from the dropdown list
    • Click Save to complete the configuration

    If specific links need their own backup strategy, use the Per-Link Configuration feature.

    Steps:

    • Find the "Need to configure individual links separately?" section at the bottom of the configuration panel
    • Click the + Per-Link Configuration button
    • In the configuration card that appears, first select the promotion link you want to configure separately from the dropdown list
    • Then choose a backup strategy for that link (Redirect to a Custom URL or Guide to Copy & Install)
    • Repeat the steps above to add more individual configurations (up to 10)
    • Click Save to complete all configurations
