You're working on a fixed annual budget but wish to test new initiatives through campaign experiments. What's an effective way to create the budget flexibility you'll need?

Allocating a percentage of the budget specifically for testing and market changes provides built-in flexibility. This approach allows you to proactively plan for new initiatives and adapt to dynamic market conditions without needing to request additional funds or disrupt your fixed annual budget. Reviewing the budget quarterly or syncing with the finance team are reactive measures that don't guarantee immediate flexibility. While anticipating query demand is good for overall planning, it doesn't directly create budget flexibility for new experiments or market shifts within a fixed budget.
