Applying a single attribution model, like last-touch, to all channels is a mistake. It undervalues top-of-funnel activities and can lead to budget cuts that starve the pipeline. Instead, measure each channel based on its intended outcome and funnel stage.

By measuring success on 'last lead source,' the company was incentivized to pour money into paid search for product trials—a clear final touchpoint. This model blinded them to the higher value of other lead types and actively discouraged investment in demand creation activities that build brand and generate higher-quality leads.

High-growth companies must transition from performance to brand marketing. The best marketers make this shift proactively, using experience to anticipate the inflection point. Waiting for data to confirm the need leads to inefficiency and a potential "death spiral."

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.

The question modern attribution should answer is not "Which channel gets credit for this dollar?" but "What are the commonalities across our most successful buying journeys, and how can we replicate them?" This moves from a simplistic, linear view to a more holistic, pattern-based understanding of customer acquisition.

Effective demand generation is a barbell, requiring strong top-of-funnel brand investment to create awareness and great bottom-of-funnel product marketing to convert interest. Viewing performance marketing as a standalone function and funding it in isolation is like "throwing money at a problem but not solving it."

Relying solely on short-term performance marketing becomes unsustainable. Brand investment acts as the fuel for these channels; cutting it means you must spend progressively more just to maintain the same results, leading to a negative spiral.

Because users treat Pinterest as a research and planning tool, the path from discovery to purchase is longer than on other platforms. Pinterest itself historically used a 60-day attribution window. Marketers should anticipate a longer consideration phase, especially for higher-ticket items discovered on the platform.

In today's market, founders cannot afford to build a product and then seek an audience. The only durable competitive advantage is building a content engine first to capture free impressions and organic reach, then monetizing that pre-existing audience with a product or service.
