Which signal should unlock a larger creative budget?

Look for a repeatable connection between the creative work and the business outcome you care about, with enough context to understand cost and attribution gaps. A standout post can justify a bounded follow-up before it justifies a permanent spending increase.

State what the extra budget will test or expand. If the current bottleneck is approval or destination conversion, more rendering may not help. Increase the constrained part of the workflow deliberately and preserve a condition for reducing the commitment if the result does not hold.
