Answer: Leave them both on until you know which one performs better
Explanation: I always suggest to spend a little bit under the max amount that you are willing and able to do so. If you always spend the max that you are comfortable with, then you always have to turn off one thing to turn on another. So in the situation where you are running ads targeting interests, and you are spending at max comfort at $100/day.
Then you hear on YouTube that you should switch to LALs after getting 100 clicks, so you turn off all of your interest campaigns and launch a $100/day LAL campaign. But the results are terrible because your LAL audiences aren't good enough yet, so you turn them off and go back to the interests.
Then the interests ads need to take 3-5 days to optimize and get back to optimal performance. Now you're like a full week and a half of bad results. The ideal situation is to spend $40-50/day on interests and then add a $40-50/day LAL campaign. Let them both run at the same time.
If they BOTH do well, keep both of them on. If you can put a dollar into an interest and make $4 back, then put $1 into a LAL audience and make $3.5 back, then you've just found more and more audiences that multiplies your money. It's the same reason why day traders don't just go all in on one stock. They diversify their portfolio instead of just trying to find that one stock that makes them all the money.
