Description

Hello, I'm Tiana.

I help companies understand precisely where their leads, sales, and revenue come from.

Many companies already have Google Analytics, Google Ads, Meta Ads, and dashboards. The next step is to transform this data into concrete answers to strategic questions:

Which marketing channels generate the most revenue?
Why don't the numbers between GA4, Google Ads, and CRM always match?
Which campaigns are actually profitable?
At which stages of the user journey do they drop off?
Can we trust the data to make decisions?

I combine technical expertise in tracking with data analysis to transform raw marketing data into actionable insights to improve business performance.
