Last non-direct click

Last non-direct click is an attribution rule that credits the most recent non-direct channel in the path. When the final interaction before converting is 'direct' (someone typing the URL or returning via a bookmark), the model skips it and credits the prior identifiable marketing channel instead — on the reasoning that direct traffic is often the downstream result of earlier marketing rather than a source of its own.

What this means

In many tools, 'direct' is the catch-all bucket for visits with no detectable referrer or campaign — typed URLs, bookmarks, some app-to-web hops, and traffic where the referrer was stripped. Crediting direct for conversions would reward an unidentifiable bucket and hide the marketing that actually drove the visit.

Last non-direct click solves this by looking back from the conversion and skipping any final direct touch, assigning credit to the most recent channel that was a real, identifiable source. It is the long-standing default behavior in Google's attribution for several reports.

Why it exists and its limits

The rationale is behavioral: a user who returns directly to convert often did so because earlier marketing made the brand memorable. Crediting the last identifiable marketing touch better reflects what initiated the return than crediting 'direct'.

The limits are those of any last-touch logic plus the direct-handling caveat. It still ignores all earlier touches except the one it credits, so it under-values assisting channels; and if a genuinely direct, marketing-independent visitor converts, the rule may credit an older channel that had little to do with the decision. It is a sensible default for cleaning up the direct bucket, not a complete causal account.

How it appears in analytics and logs

A conversion where the final touch was direct but credit lands on an earlier channel indicates last non-direct click; direct is being treated as a continuation, not an origin.

Diagnostic use case

Use last non-direct click to avoid over-crediting direct traffic, attributing the conversion to the last marketing channel that actually introduced or re-engaged the user.

What WebmasterID can help detect

WebmasterID records first-party referrer and campaign context, so it can identify the last non-direct source in a path and reason about where this rule would place credit.

Privacy and accuracy notes

Last non-direct click is a credit-assignment rule over recorded channels; it needs path and channel data, not identity. It makes no probabilistic guesses about people.
