Experience
Performance Marketing Spend Tracking
Together with the marketing team, we defined transformation rules for the UTMs in the web, and deep links in mobile, to aggregate it by the group channels (i.e., SEO, retargeting, social media, and so on).
Most of my work consisted of extensive and interactive collaboration with the marketing team to validate this data, which ended up with several changes to the UTM classification for proper control enablement. I had the opportunity to learn a lot of digital marketing and deeply understand how is the data analysis related to performance marketing.
Our new product replaced all of the worksheets and manual work of obtaining data from the source; it also sent all this data to an automatized dashboard and a cube to slice and dice the data.
Unfortunately, I cannot share a link as this is a private project.
Subscription Model KPIs
I suggested a new methodology that is specific to the subscription business model that creates market KPIs without the noise that you'd have if you used a traditional data model like the ones for eCommerce. We also recalculated the active user base, churn, conversion, and trial success rate, along with other indicators.
