How Do You Measure Incremental Growth From Continuous Influencer Activity?

Incremental growth is what continuous activity adds beyond what would have happened anyway, which is why measuring it needs a baseline or a holdout to compare against. Track the trend during and after activity against a period or region with no influencer spend. Without a comparison, you cannot tell growth from coincidence.
