Big production budgets don't reliably predict which campaigns work. The ones that do share a small set of traits that have almost nothing to do with how much was spent making them.
Campaigns that try to say everything about a brand in one burst usually say nothing memorably. The ones that work tend to commit to a single, clear idea and let every asset, every channel, restate it instead of introducing a new angle each time.
"Raise awareness" isn't a goal you can measure a campaign against. A specific, numbered target, leads, sign-ups, a sales lift by a set date, changes what gets approved along the way, because every creative decision can be checked against whether it actually serves that number.
A campaign that looks different on the billboard than it does in the retargeting ad loses the compounding effect repetition is supposed to build. The channels don't need identical assets, but they need to be unmistakably the same idea wherever someone encounters it.
Campaigns that only plan the launch moment tend to fade within a week, because there's no plan for what comes next: optimisation, a second wave of creative, a clear read on what's actually working. The strongest campaigns treat launch as the start of the measurement phase, not the finish line.
