First-Touch Attribution
An attribution model that gives 100% of the conversion credit to the first marketing touchpoint a customer interacted with. It is useful for understanding which channels drive initial awareness and demand generation. The model is calculated simply: the channel or campaign that initiated the first tracked interaction receives full credit. First-touch is especially popular among B2B marketers where the average buying cycle spans 6 to 12 months, making it important to identify which channels fill the top of the pipeline.
Why It Matters
First-touch attribution highlights the channels that introduce new prospects to your brand. It is valuable for evaluating top-of-funnel investments like display advertising, content marketing, and influencer partnerships that create initial awareness but rarely drive immediate conversions. Without first-touch visibility, brands often undervalue awareness channels by 40-60% and gradually starve pipeline-building spend in favor of bottom-funnel tactics, ultimately shrinking the total addressable audience over time.
Example
A customer first discovers a brand through an Instagram ad, later clicks a Google search result, and finally converts through a retargeting ad. First-touch attributes the entire $100 purchase to Instagram, revealing its role in driving new customer discovery. A SaaS company using first-touch found that podcast sponsorships originated 35% of enterprise deals despite generating zero last-click conversions, justifying a $50,000 per quarter podcast budget that would otherwise have been cut.

Last-Touch Attribution
An attribution model that assigns all conversion credit to the final touchpoint before a customer converts. It is simple to implement and easy to verify since only the closing interaction is tracked, but it systematically undervalues earlier interactions in the journey. Last-touch was the default in Google Analytics Universal and remains common in many CRM systems. With average e-commerce journeys involving 4 to 8 touchpoints, last-touch ignores up to 87.5% of the customer path.
Multi-Touch Attribution
An attribution approach that distributes conversion credit across multiple touchpoints in the customer journey rather than crediting a single interaction. Common multi-touch models include linear, time-decay, position-based, and algorithmic or data-driven. It provides a more complete picture of how channels work together to drive results and is especially critical for businesses with longer consideration cycles. The average B2C purchase involves 5 to 7 touchpoints, while B2B journeys can exceed 15 touchpoints across 3 to 6 months.
