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.

AI's most significant impact is not just campaign optimization but its ability to break down data silos. By combining loyalty, e-commerce, and in-store interaction data, retailers can create a holistic customer view, enabling truly adaptive and intelligent marketing across all channels.

As AI takes over campaign execution, the marketer's job shifts from micro-management to macro-strategy. They define the business rules—such as discount ranges, offer types, and creative assets—and the AI then makes millions of optimized micro-decisions for individual customers within those human-set boundaries.

New measurement tools are moving beyond probabilistic models (guessing based on IP/device) to deterministic view-through attribution. By using first-party data like platform logins, marketers can now directly match an ad impression to a purchase, solving a major measurement challenge.

Standard attribution models, even multi-touch, fail to credit influential, non-clickable touchpoints like a child watching a Netflix show that inspires a purchase. This "Hot Wheels Problem" highlights the need to account for view-through attribution and the full, often hidden, customer journey.

Instead of batching users into lists for A/B tests, AI can analyze each individual's complete behavioral history in real-time. It then deploys a uniquely bespoke message at the optimal moment for that single user, a level of personalization that makes static segmentation primitive by comparison.

Modern marketing relevance requires moving beyond traditional demographic segments. The focus should be on real-time signals of customer intent, like clicks and searches. This reframes the customer from a static identity to a dynamic one, enabling more timely and relevant engagement.

AI's growth is hampered by a measurement problem, much like early digital advertising. The industry's acceleration won't come from better AI models alone, but from building a 'boring' infrastructure, like Comscore did for ads, to prove the tools actually work.

The future role of a marketer is not as a channel expert (e.g., search marketer) but as an orchestrator of AI systems. They will design the logic, goals, and audience strategy that AI agents execute. Core skills will shift from production tasks to taste, judgment, and narrative craft.
