When a former customer returns to your database via a third-party channel, who gets the credit? Answering that question is at the heart of lead attribution for returning customers — and getting it right is essential for maximising your marketing ROI.
Why Returning Customers Complicate Attribution
Depending on your business, there may be long gaps between when a customer needs to buy from you again. In competitive markets, consumers may also avoid repeat purchases from a single brand. Over time, they may lose interest in your contact and forget who you are.
When the moment comes to buy again, they often need a gentle reminder — and that reminder frequently comes from an external source. Understanding lead attribution in this context is explored further in our post on what lead attribution is and how it helps lead generation.
A Real-World Attribution Example
Consider the following customer journey:
- You run an online DIY tools and materials business.
- Lloyd submits a form on your homepage. You capture his name, email address, and postal address.
- You nurture Lloyd over a month until he makes a purchase.
- Despite subsequent contact, Lloyd unsubscribes and makes no further purchases.
- Eight months later, Lloyd discovers your brand via a third-party website and signs up to your mailing list again.
- You receive his details from that channel — the same details as before.
- Following a welcome email, Lloyd clicks through and makes a £300 purchase.
This journey raises a clear lead attribution question: is Lloyd a new lead or a returning customer? Does your business or the third-party channel deserve the credit?
Building a Customer Evaluation Strategy
A customer evaluation process helps you segment repeat customers from those who have effectively lapsed. It does not need to be complex. Its purpose is to give you a consistent way to classify contacts and assign marketing credit accordingly.
A useful model scores customers across three criteria:
- Initial purchase — spend level, feedback ratings, and originating source.
- Repeat purchases — time elapsed since the first conversion and loyalty account sign-up.
- Nurturing interactions — ongoing brand engagement and responsiveness to contact.
In Lloyd’s case, his initial purchase was small, he provided no feedback, and he unsubscribed without further engagement. His evaluation score would be low, meaning he would not be classified as an active customer after a short window. The third-party channel that re-engaged him would therefore receive attribution credit for his return purchase.
Maximise Your Marketing ROI Through Better Attribution
Developing a lead attribution model that accounts for third-party referrals and returning customers is essential for assigning credit fairly and making informed decisions about your channel investment.
