How long does it usually take to stabilize a new ad account?

New accounts generally do not give consistent results right away. at first, spending and results can go up nd down. after about 10 days, things usually start start to settle. in the beginning i focus on setting up campaigns properly and avoiding too many changes so the system can learn faster.

In my experience, new ad accounts can be unpredictable for the first few days to a couple of weeks, depending on spend level and conversion volume.
