First-Touch Attribution

First-touch attribution credits the channel or campaign that first brought a customer to your awareness. If a customer discovered your brand through a blog post, then later clicked a paid ad and converted, first-touch gives all credit to organic search. This model is simple to implement and understand but ignores the contribution of all subsequent interactions.

For marketing teams, first-touch attribution is useful for understanding which channels are most effective at generating new demand and filling the top of the funnel. It helps answer the question: where are our customers coming from originally? Use first-touch data to evaluate brand awareness campaigns, content marketing investments, and new channel experiments. The limitation is that first-touch dramatically undervalues nurturing and conversion-focused channels. An email drip campaign that converts 30% of prospects gets zero credit under first-touch. Use first-touch as one lens alongside other attribution models for a more complete picture. It is most valuable when paired with last-touch attribution to compare top-of-funnel and bottom-of-funnel channel effectiveness.
