Telstra CMO Brent Smart says going all-in on brand building and spending big on creative isn't about "awards or ego", but because it's the safest commercial choice. Marketers making over-researched vanilla ads are "the brave" ones, because many of Australia's big brands all look the same in market, have little distinctiveness and carry a higher risk of being ignored. That means business growth is crimped and those marketers are more likely to "get sacked" because of underperformance. Smart's advice is start building your own brand metrics, with marketing science fundamentals at the core, that can be correlated to growth, base sales and incremental improvement. Marketing mix modelling can help – and can turn a $10m budget cut into a $10m budget boost, per Smart. But it won't solve the fundamental issue most brands currently face – i.e. chasing conversions is easier and faster than building demand longer-term via brand investment. But if the ad is a safe, indistinct dud, even the best media planning, optimisation and MMM can't save it, or the CMO.
