# Multi-touch attribution

Also known as: MTA, multitouch attribution

In short

Multi-touch attribution is a measurement method that distributes credit for a conversion or closed deal across several touchpoints in the buyer journey, such as an ad, a webinar, an email, and a sales call.

It differs from first-touch and last-touch attribution, which give all credit to a single interaction. B2B buying involves many people and long cycles, so single-touch views often hide what actually helped.

## Common multi-touch models

* **Linear:** Every touchpoint gets equal credit. Simple, but treats a banner view like a demo.
* **Time decay:** Touches closer to conversion get more credit.
* **U-shaped:** Most credit goes to the first touch and the lead-creation touch, with the rest shared.
* **W-shaped:** Adds a third peak at opportunity creation.
* **Custom or data-driven:** Weights come from your own conversion data. Needs enough volume to be reliable.

## How to set it up

### 1. Define the touchpoints

List the interactions you can capture: ad clicks, form fills, email replies, meetings, events. Decide whether they count at the contact or the account level.

### 2. Connect the data

Touches must be tied to people and accounts in your CRM. Most gaps come from untracked channels and unmatched contacts.

### 3. Pick a model and stay consistent

Choose one model, document it, and apply it to the same pipeline definition every time. Changing models mid-quarter makes trends meaningless.

## Example

Say a deal had five tracked touches: a paid social ad, a webinar, two emails, and a sales meeting. A linear model gives each 20 percent of the credit. A U-shaped model would give the first and the lead-creation touch the largest shares. The model shows different stories from the same journey, which is why you should treat the output as guidance.

## Limits and common mistakes

* **Untracked touches:** Word of mouth, dark social, and offline conversations never appear.
* **Contact-level only:** B2B deals involve buying committees, so credit should roll up to the account.
* **Treating it as truth:** Credit splits are rules, not proof of causation.
* **Too little data:** Data-driven models need many conversions to be stable.

## Multi-touch attribution FAQs

**What is multi-touch attribution?**

Multi-touch attribution is a way of measuring marketing and sales impact by giving credit to several touchpoints along the buyer journey, such as ads, content, emails, and meetings, instead of crediting only the first or last interaction.

**What is the difference between multi-touch and last-touch attribution?**

Last-touch attribution gives all credit to the final interaction before conversion. Multi-touch attribution spreads credit across every tracked interaction. Multi-touch gives a fuller picture of long B2B journeys, but it needs more tracking and setup.

**Which multi-touch attribution model should B2B teams use?**

Many B2B teams start with a U-shaped or W-shaped model because they highlight lead creation and opportunity creation. The best choice is the one you can apply consistently with your data, and revisit once you have enough conversions.

**Why is multi-touch attribution hard in B2B?**

B2B sales cycles are long and involve many people across channels. Touches are often untracked, contacts are not always matched to accounts, and offline conversations leave no data, so any model gives an incomplete picture.
