Google Ads is a stack of campaign types, organizing units, matching rules and automated bids. Confuse a hint with a hard targeting fence, a product feed with a text ad, or a diagnostic score with an auction input, and the account can look busy while answering the wrong question. Start with where the campaign serves, then inspect how its ad groups or asset groups are built, what signals guide it, and what the bidding strategy is actually optimizing. Finally, read the auction and delivery diagnostics in their own scope. Automation can move quickly. Your job is to make sure it is moving toward the economics you intended.

🔀 Search theme vs keyword
Search themes are PMax context inputs; keywords are controls in keyword-based campaigns. They are not interchangeable targeting objects.
🔀 Quality Score vs Ad Strength
Quality Score diagnoses keyword-related Search experience; Ad Strength rates responsive ad asset variety. Neither is Ad Rank.
🔀 Target ROAS vs ROAS
The target is an input to an eligible bid strategy. ROAS is an observed value-to-cost ratio with a declared basis.
🔀 Ad Rank vs Quality Score
Ad Rank is determined in the auction context; Quality Score is an account diagnostic and not an auction input.
