What is the most common attribution model?

Last-click attribution — assigning all credit to the final touchpoint before conversion — is the most widely used because it’s the simplest to implement. It’s also the most criticised, since it ignores every earlier touchpoint that introduced and nurtured the customer.

Why does the attribution model matter for social media?

Social posts often start customer journeys rather than finish them. Single-touch models like last-click tend to under-credit that top-of-funnel role, making social look less effective than it is. Multi-touch models give a fairer, though harder-to-track, view.

What is multi-touch attribution?

Multi-touch attribution distributes conversion credit across several touchpoints rather than a single one, using rules like linear, time-decay, or position-based weighting. It gives a more complete picture of a multi-step journey but requires more sophisticated tracking to implement.

Quick definition

An attribution model is a rule set that decides how credit for a conversion is split across the marketing touchpoints a customer met before buying.

What an attribution model is

An attribution model is the logic a marketing team uses to assign credit for a sale, sign-up, or lead across the many touchpoints a customer encountered on the way to converting. Because most buyers see several posts, ads, emails, and search results before acting, the question of which touchpoint "caused" the conversion has no single right answer — the model is the agreed-upon rule for splitting that credit. Common models include last-click (all credit to the final touchpoint), first-click (all credit to the first), linear (credit split evenly), time-decay (more credit to touchpoints nearer the conversion), and position-based (weighted toward first and last).

How it shows up in social media measurement

Attribution shapes how social media appears to perform. Under a last-click model, a paid search ad or a direct visit often gets the credit while the social posts that first introduced the brand look worthless — a well-known blind spot, since social frequently sits at the top of the funnel. Multi-touch models spread credit more fairly but are harder to track, especially with dark social sharing and privacy changes that limit cross-platform tracking. The model you choose can make the same campaign look like a success or a waste.

What it means for marketers

No model is objectively correct; each emphasises a different part of the journey. The practical move is to pick a model that matches your goals, apply it consistently, and understand its bias — last-click undervalues awareness, first-click undervalues closing. Comparing results across two models often reveals more than trusting one. Pairing attribution with UTM codes and consistent tracking keeps the data usable, while remembering that untracked, offline, and dark-social touchpoints mean no model captures the full picture.
