What's inside

Nine sections. The whole build, and the parts that went wrong.

The month the client killed our adsAnd the restructure that took the account from 3.4x to 11x in two weeks.

The Rule of Fives1.9% of videos drove 45% of revenue. The three numbers that identify them.

What broke, and the fixesEight real incidents, including two ad account suspensions.

What it does not proveThe refund rate, the base effect, and the half of this that was not our work.

Most case studies only show you the win

So this one prints the refund rate, the base effect, and the channel we didn't build. Read section 8 first if you want to know whether the rest is worth your time.
