The Ecomm Analyst

The standard way DTC brands measure influencer ROI is with a discount code. Creator gets a unique code, the brand counts uses, divides cost by orders, calls it done. This is a wildly incomplete measurement.

The discount code captures a fraction of the actual driven revenue. Most viewers who become customers don’t use the code. They go to the site directly, they search the brand on Google, they click through later from a different platform. The code captures the most price-sensitive subset of the audience the creator drove. Everyone else gets attributed somewhere else.

I had a brand that paid a creator $8k for a TikTok partnership [PLACEHOLDER: numbers from a specific client engagement, please confirm before publishing]. Discount code use generated 23 orders at average AOV. Pure code-based math said the partnership lost money. Looking at the broader attribution picture told a different story.

Three signals I look at for creator attribution.

Direct traffic spike on post date. Most creator-driven sales come through direct (the viewer remembers the brand name and types it in or searches it). Direct traffic on post day is usually 2 to 4x the daily baseline if the creator drove anything. If direct traffic is flat, the creator didn’t move the needle regardless of code redemptions.

Branded search lift. Google Trends and Search Console will show branded search volume changes around post date. A creator who drives meaningful awareness will create a search spike that lasts 3 to 7 days. No spike, no real reach.

Post-purchase survey responses. New customers in the week after the post will mention the creator or platform if they came from there. This is the highest-signal data because it’s the customer telling you directly. Run it through ThoughtMetric to slice survey responses by week and you can see the creator’s contribution surface even when the discount code numbers look weak.

Back to the brand with the $8k creator deal. Code redemptions said 23 orders. Direct traffic spiked 3.4x for two days. Branded search rose 60% for a week. Post-purchase survey responses citing TikTok jumped from 8% to 22% for the following 30 days. The actual driven revenue, when I added it up across signals, was closer to $40k than to the $1,500 that the discount code claimed.

The discount code is a useful lower bound on what a creator drove. It’s a wildly inaccurate read on actual impact. If you’re making spend decisions based only on code redemption math, you’re going to underinvest in creators who reach engaged audiences and overinvest in creators who reach price-sensitive ones.
