What happened
Shopify says the update focuses the default sessions experience on human visitors where the Human or bot filter is available and classifies bot or system traffic more consistently.
Valid shopper journeys can remain visible even when they do not include a standard pageview, according to Shopify.
Sessions, conversion rate, and other session-based metrics may look different after September 21, 2026, while orders, sales, and customer counts are not changed by this measurement update.
Business relevance
Why it matters
A before-and-after comparison of Shopify Analytics reports may show a measurement shift rather than a change in shopper demand or site performance.
Teams using sessions to assess acquisition quality or conversion should treat September 21 as a reporting break and establish comparisons from the new baseline.
