Key Terms in This Article

Attribution

Attribution identifies user actions that contribute to a desired outcome and assigns value to each. It reveals which marketing touchpoints drive conversions.

Causal Model

A Causal Model is a mathematical representation describing the causal relationships between variables, used to reason about and estimate intervention effects.

Data Driven Attribution

Data-Driven Attribution uses machine learning to analyze customer touchpoints and assign conversion credit. It determines the true impact of each marketing channel.

First Click Attribution assigns all conversion credit to the first marketing touchpoint. Causal inference evaluates if first touchpoints truly drive conversions or if other interactions have greater causal impact.

Incrementality

Incrementality measures the true causal impact of a marketing campaign. It quantifies the additional conversions or revenue directly from that activity.

Incrementality Testing

Incrementality Testing measures the additional impact of a marketing campaign. It compares exposed and control groups to determine causal effect.

Retargeting

Retargeting is online advertising that targets users who have previously interacted with your website or content. Attribution analysis shows the causal role of retargeting in driving conversions and improving ad spend.

TikTok Ads

TikTok Ads are advertisements on the TikTok platform. They allow brands to reach younger audiences through short-form video content.
