Your agency isn't underperforming because you hired the wrong one. It's underperforming because of how agencies are built — retainers that reward activity over outcomes, account managers who translate rather than execute, and five specialists optimising five corners of a business none of them can see whole. These pieces take apart the structure: why proposals are engineered to win signatures rather than results, what "weekly optimisations" actually look like inside an account, and why hiring a full-service agency doesn't solve a problem that's structural rather than personal. Written from 19 years inside the industry, including the parts agencies would rather you didn't ask about.
