Shopify’s September 2026 analytics update: what eCommerce managers need to know

If your Shopify conversion rate has moved recently, it is tempting to credit a new campaign or worry that something on the site has broken. Before making that call, check the date.

Shopify changed how it measures sessions and filters bot traffic between 21 and 23 September 2026. That can change your reported sessions and conversion rate even when customer behaviour has not changed.

For eCommerce managers preparing reports or planning the next round of site improvements, this matters because it affects the baseline used to judge performance.

What has Shopify changed?

According to Shopify’s announcement, the update changes session reporting in three ways:

  1. Sessions follow continued customer activity. A visit that continues past midnight UTC is no longer split into two sessions solely because the date changed.

  2. Some journeys without a standard pageview now count. For example, someone going directly to checkout from a cart link may now be included as a session.

  3. Identified bot sessions are excluded by default from session-related reports. In reports that support the Human or bot session filter, you can change the filter to inspect them.

One change may reduce your session count while another may increase it. Shopify says the update does not change orders, sales or customer counts.

Why might conversion rate change without more sales?

Shopify calculates online store conversion rate using sessions. If the number of reported sessions changes, the conversion rate can change even when order volume stays the same.

Imagine a store with 100 orders and 5,000 reported sessions. Its conversion rate is 2%. If revised reporting shows 4,000 sessions for the same 100 orders, the reported rate becomes 2.5%.

That looks like an improvement, but the store has not gained any additional orders. The reverse can happen if newly counted journeys increase the session total. Shopify says other session-based measures, including add-to-cart rate and checkout conversion rate, may also look different.

What should eCommerce managers do now?

1. Mark the update on your reports. Add a note around 21–23 September so anyone reviewing performance knows that Shopify changed its measurement.

2. Check orders and sales alongside sessions. If conversion rate changes but orders and revenue remain steady, investigate the reporting change before treating it as a commercial result.

3. Establish a new baseline. Use data from after the update to assess future trends in sessions, conversion rate and other session-based metrics.

4. Keep bot filters consistent. In reports that support it, check the Human or bot session setting when comparing periods. Shopify notes that using the same filter does not make sessions measured before and after the update directly comparable.

5. Review custom reports and connected apps. If they use session data from Shopify Analytics, their figures may change too. Check how each report defines its metrics before comparing results with historical targets.

You can start in Shopify Admin → Analytics → Reports, then open a sessions report such as Sessions by landing page or Sessions by device. Shopify’s help guide walks through the available comparisons.

What does this mean for marketing decisions?

A dashboard metric needs context. If conversion rate rises but orders and revenue do not, it is too early to say that a new design or campaign worked. Equally, a lower rate does not automatically mean your checkout has worsened.

Look at the full customer journey: the quality of traffic reaching key pages, product engagement, basket activity, checkout behaviour, orders and revenue.

If paid traffic is growing without corresponding sales, the next step may be to review targeting and landing pages. Our PPC approach considers the page customers reach as well as campaign performance.

For organic traffic, our SEO work focuses on attracting relevant visitors, not simply increasing visits.

The takeaway

Shopify’s September update is a measurement change, not a trading result in itself. Annotate your reporting, establish a new baseline and check commercial outcomes before drawing conclusions.

If the data then points to a genuine customer journey problem, turn that finding into a specific improvement to test. If your team needs help interpreting store performance and prioritising the next steps, explore our Shopify Priority Support or get in touch.
