With AI enabling precise control over media spend, key performance indicators are changing. Brands now move beyond simple Return on Ad Spend (ROAS) to more sophisticated metrics like incremental ROAS and contribution margin, reflecting a new emphasis on profitable growth rather than just volume.

The 'MQL death cycle' is over. Forward-thinking marketing organizations should align around Net Annual Recurring Revenue (Net ARR) as their ultimate measure of success. This metric, which combines new customer acquisition with retention, forces a focus on the entire customer lifecycle and proves marketing's contribution to sustainable business growth.

Gap's Head of Digital argues that a lack of brand investment forces performance marketing to work harder and become less profitable. Strong brand relevance makes all other marketing efforts more efficient, creating a symbiotic relationship.

Brand campaigns reach the 95% of buyers not currently in-market. Instead of relying on vanity metrics, Square ties this investment to business outcomes by tracking the subsequent lift in organic traffic, which they've found converts better than paid channels.

The speaker coins "technoplasmosis" for when tech vendors persuade a company's finance department to adopt marketing metrics that favor selling tech stacks (e.g., click-through rates). This shifts focus to short-term, transactional activities and away from long-term brand building, which is more valuable.

Lifetime Value (LTV) is meaningless in isolation. The key metric for investors is the LTV to Customer Acquisition Cost (CAC) ratio. A ratio below 3:1 indicates you're overspending on growth. The 3:1 to 5:1 range is healthy, while anything over 5:1 is world-class and attracts premium valuations.

A common attribution error is assigning all sales to paid marketing activities. In reality, most brands have a strong "baseline"—sales that would occur even without marketing. Accurate measurement requires modeling this baseline first, then attributing only the incremental lift from campaigns.

Escape the trap of chasing top-line revenue. Instead, make contribution margin (revenue minus COGS, ad spend, and discounts) your primary success metric. This provides a truer picture of business health and aligns the entire organization around profitable, sustainable growth rather than vanity metrics.

Shift the mindset from a brand vs. performance dichotomy. All marketing should be measured for performance. For brand initiatives, use metrics like branded search volume per dollar spent to quantify impact and tie "fluffy" activities to tangible growth outcomes.
