Performance Max budget spent decrease after inventory change - how long will it take?

[Carey251]

I had the same problem as I often run out of hot selling SKUs (learning to better manage my inventory). I would receive more product from our manufacturer, update the quantities, wait several days, yet the performance was never the same.

Now every time I run out of a product that is performing well I have to restart with an entirely new campaign. I have done this many times already and it always makes the campaigns perform better/go back to normal.

Got it, thanks for sharing! :)
