Exploratory data analysis for a marketing team

A rigorous analysis of campaign, CRM and web data that reallocated budget toward the channels that actually converted.

Challenge

Three platforms, three sets of numbers, and no confidence in which channels drove sales.

What we built

  • A consolidated dataset in BigQuery joining ad platforms, CRM and web analytics.
  • Attribution and cohort analysis, with clear write-ups of what could and could not be concluded from the data.
  • A dashboard the team maintains themselves.

Results

Reallocating spend based on the analysis lifted conversion by roughly 18% the following quarter, and the team stopped arguing about whose numbers were right.
