Last-click still wins the row. The organic week still happened.
A conversion that ends on a paid search click is not proof that organic pages were idle. This note covers how we write both facts in the same table without pretending we saw the full path.
Most conversion tables still give the last paid click the entire row. That is a recording rule, not a story about how a person spent the week. When we write a marketing attribution report for paid and organic channels, we keep the last-click row and we add a second view that simply lists what else was active in the same dates.
Suppose branded organic search rose on Tuesday through Thursday, a paid search campaign stayed on the whole week, and the sale posted Friday after a branded paid click. Last-click will name paid search. The organic week still happened. We put organic sessions, ranking notes you supplied, and the paid click on one page, then we write the sentence that finance can live with: credit in the last-click table is paid search; concurrent organic activity is documented and not converted into a fake fraction.
We do not stitch a person-level path unless you actually have that path. Shared office computers, missing tags, and app browsers will keep a share of conversions in unassigned. That column is not a failure of the report. It is the part of the record that would be dishonest to fill.
If your agency wants a single ‘winner’ for the week, the walkthrough is where we say no. The document they take back should show the paid click, the organic movement, and the limit of the files. That is the whole craft of this kind of reporting.
