How the desk works
One test at a time is slow. CTRL runs several and keeps what wins.
Most brands test one ad, wait, then start again. CTRL keeps a few winners live in each channel and puts the next test beside them, so you never go back to a blank page.
01 · Read
See what is working
Each week CTRL reads your live ads, pages and emails and spots the winners and the ones at risk.
02 · Draft
Get the next tests written
New ads, page changes and emails are drafted from what is already winning, ready for you to check.
03 · Queue
Launch inside your limits
Tests go live only inside the budget and rules you set. Winners stay on while the next ones run.
