600 sites in 6 months: enterprise analytics governance at scale

Six hundred properties across multiple geographies. One consistent measurement framework. Six months. Without the six-month deck.

Six hundred properties. Multiple geographies. Most of them with a different team, a different CMS, a different stack. A measurement strategy that needed to look the same from the outside but flex on the inside.

The big-consultancy answer would have been a six-month framework. Forty slides. A change-management plan. A quarterly steering committee. We didn’t have six months for the framework alone. We had six months and 600 sites.

The math forces a different approach.

A pattern library, not a framework

Twelve content types. One tagging spec per type, defined as code in version control. A page on a site identifies which type it is and inherits the spec. New sites pick up the spec on day one. Existing sites get audited against it. The spec was the deliverable.

Governance lived in the repo, not in a steering deck. When marketing asked a question, we showed them the spec. When a regional team needed something custom, the request went through a pull request. Decisions were visible. Drift was visible. The same dimension calculated three ways was not possible because there was one place to define the dimension.

DAR cadence at scale

Two-week iteration cadence. Diagnose, Act, Reflect — the same loop a Fractional Head of Analytics runs on a single brand, just compressed and parallelized across hundreds. Diagnose what broke. Act on the smallest fix. Reflect with stakeholders. Each two-week loop shipped enough to keep momentum and small enough to absorb feedback before the next loop.

The Horizon was clear: the same measurement framework reads consistently across every property by month six. We hit it.

What the case shows

Most marketing data problems aren’t accuracy problems. They’re governance problems. At 600 sites there is no other way. The same is true at 6 sites, just less obvious.

Tools didn’t fix this. Visibility did. Visible lineage. Smaller iterations. Difficult conversations brought to a foundation everyone could see.
