## This is an FAQ article explaining the incrementality measurement in a post-privacy world

Last touch attribution will continue being available on an aggregate level (such as campaign), allowing marketers to use last touch as a proxy for optimization of creative, and engagement.

[Incrementality measurement a method](https://www.incrmntal.com/the-best-methods-for-incrementality-measurement) to understand the true value of Advertising spend using a statistical algorithmic approach.

Incrementality can provide insights in granular levels over campaigns, demographics, vendors, geo location, contextual features. These insights can be used in an operational - tactical level.
