influencer-tracking

Create a unique UTM link per creator with utm_medium=influencer and utm_content set to the creator handle, then pair it with a unique discount code. UTM links track web traffic in GA4 while codes capture purchases made days later via direct or organic channels.

In GA4, filter Traffic Acquisition reports by Session medium = influencer and add utm_content as a dimension to compare creators. For revenue, use Monetization → Ecommerce Purchases filtered by the influencer medium, and combine with discount code revenue from your platform.

Yes, all three platforms support unique discount codes with usage limits and expiry dates, and GA4 UTM tracking works across all of them. Shopify also offers discount code reports under Analytics, while WooCommerce provides coupon analytics.

Set a per-customer usage limit of one and an expiry date matching the campaign end date. Monitor daily usage velocity for spikes that indicate the code leaked to deal sites.

Calculate revenue per 1,000 followers by dividing total revenue by follower count in thousands. This normalized metric often reveals that micro-influencers outperform macro-influencers on a per-reach basis.
