2026 Annual Report on Causal Measurement

Most marketing dashboards measure activity. The best brands measure impact.

Prompt of the Week

Most marketing budgets overfund demand-capture channels and underfund demand creation. This week’s prompt, using Lifesight MCP:

“Stress-test my Q4 plan. Where am I over-investing, and what would a 20% reallocation to upper-funnel channels look like in incremental revenue?”

In this example, Brand Search, Retargeting, and Branded Shopping showed low marginal iROAS of 1.2–1.5×. Reallocating 20% of spend to upper-funnel channels like CTV, YouTube, and TikTok increased projected incremental revenue from $14.2M to $16.9M.

Same budget. +$2.7M incremental revenue. +19% lift.

Why MTA Is Giving You the Wrong Answer

Why MTA Is Broken

Multi Touch Attribution (MTA) doesn’t measure marketing effectiveness, it measures the appearance of it. It can’t tell an ad that drove a sale from one that just reached someone already going to buy, which is how 50-70% of “attributed” retargeting conversions turn out to be demand you already owned.

Our latest blog breaks down the 5 reasons MTA is broken and why unified measurement (MMM + incrementality + calibrated attribution) is the only honest fix.

Tip of the Week

Your Measurement Is Only as Good as Your Experiment Design

Running a geo-test or holdout sounds scientific, but a bad experiment design is worse than no test at all. It gives you false confidence.

The Most Common Mistakes:

  • Test and control regions aren’t statistically comparable (different population sizes, seasonality, or baseline sales trends)
  • Test windows are too short to account for delayed purchase cycles
  • Only measuring the advertised product instead of total revenue (see: Halo Effect)

The Checklist Before You Run Any Test:

  1. Match regions on at least 3 historical revenue periods
  2. Run for a minimum of 2-4 weeks (or one full purchase cycle)
  3. Define your success metric before you start, not after you see the results

Good measurement isn’t just about what you test. It’s about whether your test was designed to tell the truth.
