    If it’s a lot more products or just a lot of products overall relative to budget then Google will (a) need a few weeks to adopt and (b) may struggle to optimize.

    It’s always best to add more products gradually with things being relative. If you currently advertise 5,000 and you add 100 that’s nothing. But if you currently advertise 100 and add another 100 that’s basically pushing it into learning mode.
