Budget only makes sense in commercial context.
The right level depends on market demand, average CPC, conversion rate and the value of each result.
This guide is written to support real implementation decisions rather than provide a generic checklist.
Key points to understand
Low demand can cap spend even when more budget is available.
Competitive markets require more budget to generate enough qualified traffic.
Target CPA, lead quality and customer value determine what spend can be sustainable.
Use budget as a decision framework.
A realistic plan should distinguish learning, maintenance and scaling phases.
