<b>Tracking domain health — keep your redirect domain alive</b>

A flagged tracking domain silently kills delivery — clicks 403 and you blame the offer. Audit the domain on a schedule.

Monthly domain health checklist:

— Check the domain against major blocklists (it gets flagged by association if a neighbor on shared infra spammed)
— Confirm SSL certificate validity and expiry over 30 days out — an expired cert drops every click
— Verify DNS resolves from multiple GEOs, not just yours
— Test the domain isn't blocked inside Facebook/Google by pasting it in a message/ads preview
— Keep a warmed backup tracking domain ready, pre-SSL'd, so you can swap in minutes

Domain hygiene rules:

— Never run your main money domain as the click redirect domain — isolate them
— Use a fresh tracking domain per major traffic source to contain flag blast radius
— Rotate domains before they're burned, not after delivery already tanked

Keep a dated log of which domain serves which source so a swap doesn't break attribution.

Save this SOP. Run this before every launch.
