Introduction

An attribution model assigns credit for a conversion across the different touchpoints that led to it. When a prospect clicks a LinkedIn ad, reads three blog posts, watches a webinar, and receives two emails before filling out a contact form, which touchpoint deserves credit? First-touch, last-touch, or something in between? Your attribution model answers this question and directs marketing budget accordingly.

Different models allocate credit differently. Last-touch attribution credits the final interaction (the contact form). First-touch credits the initial discovery (the LinkedIn ad). Multi-touch models (linear, time-decay, or custom) split credit across all interactions. The choice matters because it changes how you measure channel effectiveness and where you invest next.

The challenge is that there's no single 'correct' model. Last-touch overstates the value of bottom-funnel activities like contact forms. First-touch overstates awareness channels and ignores what actually moved the prospect closer to buying. Most sophisticated companies use custom models: different weights for different channels, different rules for leads versus customers. But many organisations haven't thought about this at all, leading to misallocated budget and false conclusions about what works.

Why it matters

Directs budget allocation

If you believe last-touch attribution, you'll invest heavily in retargeting campaigns, demos, and sales support—the final touches. If you believe first-touch, you'll invest in awareness and demand generation. Reality is both matter; an attribution model clarifies the balance. Without one, budget decisions are guesses.

Prevents channel conflict

Without attribution, different teams fight over credit. Sales claims SDRs 'actually close deals'. Marketing claims their campaigns 'generate all the leads'. Attribution settles disputes by showing each channel's real contribution. This reduces friction and enables collaboration.

Reveals true funnel efficiency

Attribution shows which channels attract people who actually convert versus which attract browsers. A channel with high traffic but poor downstream conversion is inefficient. A channel with low traffic but high conversion is underinvested. Attribution uncovers these gaps.

How to apply it

Start with last-touch for simplicity

If you have no attribution model, last-touch is the easiest baseline. Credit the final interaction before conversion. It's imperfect but actionable. Most analytics platforms default to this because it's easy to measure in their systems.

Graduate to first-touch to understand awareness

After stabilising last-touch, add first-touch reporting. Compare the two. Channels that are high in first-touch but low in last-touch are awareness channels driving discovery. Channels high in both are full-funnel powerhouses. This comparison guides channel strategy.

Implement linear or time-decay if you can

Linear attribution splits credit equally across all touchpoints. Time-decay gives more credit to recent interactions. These are more sophisticated than first/last-touch and reveal the true journey. Most analytics platforms support them natively.

Build a custom model aligned to your funnel

As you mature, build a model reflecting your business. If your sales cycle is long and most conversions need multiple touches, weight the middle interactions heavily. If initial discovery matters more than final touch, adjust first-touch weight. Document your model so stakeholders understand it.

Last-touch attribution problem at a SaaS company

A B2B SaaS firm using only last-touch attribution credited a demo request entirely to retargeting display ads. But the actual journey: prospect saw a LinkedIn post (week 1), downloaded a guide from organic search (week 2), attended a webinar (week 3), then clicked a retargeting ad (week 4) before requesting a demo. Last-touch credit went entirely to retargeting, making it appear 10x more effective than it was. The company overinvested in retargeting while neglecting the webinar that actually moved interest.

Multi-touch attribution reveals full-funnel contribution

Using multi-touch linear attribution, that same SaaS company discovered: LinkedIn post (25% credit) for awareness, guide download (25% credit) for consideration, webinar (30% credit) for engagement, and retargeting (20% credit) for final push. This revealed the webinar's outsized importance in the journey and justified doubling down on event marketing. Budget shifted accordingly, improving overall conversion.

Custom time-decay model in enterprise sales

A financial services firm implemented time-decay attribution giving 50% credit to interactions in the final 30 days and 50% to earlier touches. This reflected their lengthy sales cycle where early awareness matters but final engagement before a meeting is critical. The model showed that account-based marketing efforts (which created multiple touchpoints near close) contributed 3x more than general campaigns, justifying the shift to ABM strategy.
