Since no one is answering, I thought I could share my experience. Right now this is my budget increasing chart for CBO's and it works just fine for my projects and clients:
- Budget up to $100/day - double it. $20 => $40, $40 => $80 etc.
- $100 - $200 - 80%
- $200 - $500 - 60%
- $500 - $1000 - 50%
- Over $1000 - manually, depending on the metrics.
i tested it, you don't want to increase by more than 50% per day, you will restart the learning phase. you may be able to push 60 or 70%, but i haven't tested that
$100 per day to $150 per day is okay. but $100 to $200 is not. that's why i recommend starting higher at $300 or $500 per day. it makes it smoother to go into scaling
btw, all of this may not even matter because i still haven't figured out how to get out of "learning limited". i'm testing 1 campaign -> 1 ad set -> 1 ad, broad targeting at $500 per day. if that gets learning limited still then i have no idea what the fuck the problem is, and at that point i would recommend others to just not even bother with it AS LONG AS you are profitable. my campaigns are profitable so even if they get learning limited i will continue to scale them up 40-50% per day
another thing: about retargeting budget, people grapple and debate about what is best. right now i think 10% of your main campaign budget should be okay.... so if you have 1 active CBO at $500 per day, make your retargeting $50 per day. i THINK this should be okay. it really all depends on how much you wanna squeeze out of it. if you go too high per day on retargeting, you risk exhausting your retargeting audience. too low and you're not getting the most profit, so it's a sweet spot
right now i'm running $500/day CBO and $50/day retargeting. tomorrow i'll be increasing $800/day, then $1200/day, then $1600 day, then $2400 day, then go from there
