Since platforms like Google and Facebook have a vested interest in overstating their impact within their "walled gardens," a simple, qualitative approach can be more revealing. Adding a "How did you hear about us?" field to your forms provides direct, self-reported data from customers, helping you identify influential channels that complex models might miss.

Relying on last-touch attribution creates a feedback loop that over-invests in bottom-of-funnel channels like branded Google search. This model fails to account for the preceding marketing actions that prompted the search, misallocating budget away from crucial brand discovery activities.
In the beginning, don't get lost in the weeds of perfect analytics and UTM parameters to track every subscriber source. It's a form of procrastination. For attribution, just add a simple question to your welcome email: "Where did you find the newsletter?" This is all the data you need early on.
Vector's VP of Marketing skipped messy UTMs for her influencer pilot. Instead, she tracked success by setting up alerts in their call recording software (Fathom) for mentions of influencer names, coupled with a "How did you hear about us?" form field.
Many founders operate on flawed assumptions about how they acquire customers. Analyzing marketing data often shatters these myths, revealing that sales and traffic come from unexpected sources. This discovery points to untapped growth opportunities and where marketing energy is best spent.
Standard attribution often credits Google due to last-click bias. To find true sources of influence, mandate that the sales team asks every new customer: "How did you *truly* hear about us?" and "Who or what influenced you to sign up *now*?". This reveals the real people and channels driving decisions.
Go beyond standard W-shaped or last-touch attribution models. Create "influence reports" that measure the sheer frequency a channel appears in any revenue-generating journey. This provides a different lens, showing which channels are consistently present and influential, even if they don't get direct attribution credit.
Don't abandon attribution; evolve it. The old model of single-touch software attribution is outdated. A modern approach triangulates data from software (GA4), self-reported forms ("How did you hear about us?"), and conversational intelligence tools, using AI to identify common buying journey patterns.
Direct attribution models are flawed because platforms like Google and Facebook use tracking pixels to claim credit for sales that would have occurred anyway. Smart marketers are returning to older methods of measuring lift from campaigns rather than relying on misleading platform data.
Relying on UTM link clicks for B2B influencer campaigns is a failing strategy, as social platforms penalize external links and users rarely convert directly. Instead, use a combination of time-series analysis (correlating campaigns to signup spikes) and self-reported attribution on forms to get a more accurate picture of an influencer's impact.
Instead of chasing perfect attribution, recognize that customers will explicitly tell you how they found you. At Drift, prospects on sales calls would frequently mention being fans of their podcast. This qualitative data from the front lines is often the most direct and powerful measure of brand impact.
