23 September 2026 · Reporting clarificationUse a consistent reporting dataset
The report calculator and lessons 1.2 and 6.2 now make the click-based practice assumption explicit. A conversions total that includes view-through events should not be divided by clicks and described as a click conversion rate.
Earlier saved report snapshots may say “Click-to-purchase rate.” Review the source and attribution basis before reusing that label. Your saved work is preserved; this clarification does not rewrite an accepted report.
