Google & YouTube Ads System

On Search, the customer arrives already knowing they have a problem and already looking for the solution. On YouTube, the viewer came to watch something else and you are the interruption. A Search ad that states the offer plainly wins. A YouTube ad that states the offer plainly gets skipped. Running one with the other's playbook is the most expensive mistake in the platform. The system works top down through four layers, because a problem at a lower layer cannot be fixed by optimising a higher one. LAYER 1, intent mapping: sort the market into solution-aware, problem-aware, competitor and research, then set a match-type policy for each. LAYER 2, architecture: one theme per ad group, one intent per campaign, one budget per profit centre — plus the splits most small accounts never make (Search from Display, brand from non-brand, geography when cost varies). LAYER 3, assets: fifteen-headline responsive search ads that actually differ, and the five-part video structure that survives the skip, with three argument variants to test. LAYER 4, measurement: verifying conversion tracking before optimising anything, choosing bid strategy by data stage, and respecting the learning period. Includes the negative keyword starter list, the statistical honesty threshold before you may kill a keyword, and the rule that Performance Max is a wrapper, not a strategy.
