How to test deep links on mobile

Test the installed-app path, the web fallback, and the social in-app-browser path before sharing a Link.

Choose devices and browsers to test

  • Test iPhone or iPad with the destination app installed.
  • Test Android with the destination app installed.
  • Test at least one device without the app or where app opening is blocked.
  • Test desktop to confirm the normal web destination.
  • Test inside Instagram or TikTok when that is where the link will be published.

Run each test

  1. Copy the public Link.
  2. Open it from the real browser or social placement you are checking.
  3. Confirm the correct content opens, not just the correct app.
  4. If the app cannot open, confirm the fallback reaches the intended web page.
  5. Check that affiliate and campaign parameters still look correct where the destination exposes them.
  6. Record the device, operating system, browser, app-installed state, and result.
Redirect settings with recognized app, fallback description, and Test redirect control.
Use Test redirect while checking the same Link across your target devices and browsers.

Social browser checks

  • Confirm the Link's saved Mobile behavior setting matches the campaign.
  • With Mobile behavior on, check that the Link opens the app or the external-browser fallback when tapped inside the social app.
  • With Mobile behavior off, confirm the destination stays in the social app's in-app browser without a choice screen or app timer.
  • Do not assume a Safari or Chrome result proves the Instagram or TikTok result.
