Case: rotating tracking domains recovered 23% of clicks killed by a blocklist

Case: rotating tracking domains recovered 23% of clicks killed by a blocklist

The drop: overnight, one tracker's logged clicks fell 23% while the traffic source's reported clicks held flat. Same campaigns, same spend, fewer arrivals.

The investigation:
1. Tested the tracking domain from a clean mobile connection — it loaded
2. Tested through the actual traffic source's in-app browser — it hit a 'deceptive site' warning
3. Checked the domain against a public blocklist API — it was flagged 2 days prior
4. The flagged clicks were being eaten by the in-app browser before reaching the tracker

The domain rotation procedure:
— Registered three fresh tracking domains on separate registrars
— Set the tracker to rotate the primary redirect domain across them
— Added a daily automated check against the blocklist API; any flagged domain auto-drops out of rotation
— Kept the burned domain parked for cleanup, didn't reuse it

Outcome: logged clicks returned to within 2% of source-reported clicks — a 23% recovery on identical spend. The auto-check has since caught two more flags before they cost volume.

A tracking domain is consumable. Run more than one, check them against blocklists daily, rotate the moment one burns.

Save this SOP. Run this before every launch.
