How to Fix Broken Deep Links & Push Notifications
You’re not crazy — the deep links are broken. This ebook gives you the tools to identify, validate, report, and resolve deep link and push notification failures that cost you customers, including how to compile the “receipts” on failure circumstances.
If you have ever watched a campaign underperform and suspected the links, you were probably right. Deep link and push notification failures are common, silent, and almost impossible to see from the dashboard: attribution just goes missing, and the user who tapped and landed on the wrong screen never files a ticket.
This guide walks through the failure modes we see most on real devices: universal links that open a webview login despite the app being installed, push notifications that deliver on one OS version and vanish on another, cold-start handoffs that drop a parameter, and re-engagement flows that pass in the simulator and fail in the field.
For each, we show how to reproduce it the way a user experiences it — from the real source app, on a real device, with the app in the real state — and how to compile the evidence an engineer needs: the device and OS, the channel, the exact link, a video of the tap, and the device log at the moment of the handoff.
Then we show how to stop chasing them one at a time. Continuous validation on real devices catches a broken link in hours instead of after the spend, and a verified defect report with receipts turns a growth-team suspicion into an engineering fix.
