Understand what this lesson solves
These campaign types are not substitutes for one another. Use the same product to separate the evidence for active search, product comparison, and automated expansion before deciding where a budget belongs.
Verify your account, product data, and conversion signals, then choose Search, Shopping, or PMax and run your first controlled optimization cycle.
Lesson outline
- 1Choose the current store shape
- 2Fill the four traffic jobs
- 3Use one 20oz tumbler to split Search, Shopping, and PMax roles
- 4Pull the admin evidence
- 5Run the PMax entry check
- 6Split blended ROAS contamination
- 7Write the 30-minute review sheet and copyable lesson notes
Public core framework
- Start by choosing single SKU, small catalog, large catalog, or mature brand. The store shape decides whether the first move is Search demand validation, Shopping product-fact validation, or PMax automation after boundaries are clear.
- For Search, Shopping, PMax, and brand traffic, write the job, input dependency, primary reading, contamination risk, and what it cannot prove. Do not only write which campaign has higher ROAS.
- For Search, write search terms, ad promise, and Final URL. For Shopping, write Merchant Center item, GTIN, price, availability, and product group.
