Why does my TikTok ad link redirect to a different domain?

Topic summary

Users are experiencing an issue where TikTok ads automatically display their Shopify subdomain (e.g., 6304a2-3.myshopify.com) instead of their custom primary domain (e.g., dashdine.store), even though the custom domain is properly configured in Shopify settings.

Key Concerns:

  • While the myshopify.com link does redirect to the custom domain, the unprofessional appearance of the Shopify URL in ads may negatively impact click-through rates
  • Users want their branded custom domain to display directly in TikTok ads

Potential Workaround:
One user reported success by creating ads directly through TikTok Ads Manager rather than the TikTok Shopify app, which also provides additional audience targeting options.

Current Status:
Multiple users continue to experience this issue with no confirmed resolution. The discussion remains open with users seeking a definitive fix.
