It is normal to see differences between visitor counts reported by Alia and Shopify. These discrepancies are expected because both platforms use different methods and datasets to identify visitors, bots, and returning users.

This article may help if you notice:

Alia and Shopify use different systems to determine what qualifies as bot or automated traffic.

Because of this:

In many cases, these differences are relatively small, but for some stores they may become more noticeable depending on traffic patterns.

Another common reason for discrepancies is how returning visitors are identified.

Because Alia only begins building visitor history after installation, some visitors may be classified differently compared to Shopify, which may already have historical visitor data.

For example:

In this scenario:

Both platforms may classify visitors differently because they rely on different tracking methodologies and historical datasets.

In some cases, rolling-period visitor totals may not exactly match the sum of daily reports because analytics platforms may calculate visitors differently across reporting windows. As a result, totals shown in different views may not always align perfectly.

Another common source of confusion is the difference between Shopify Sessions and Alia Visitors.

A Shopify Session represents a browsing session on your store. A single person can generate multiple sessions over time—for example, if they visit your store several times in a day or return on different days. As a result, session counts can be higher than the number of individual people who visited your site.

An Alia Visitor represents a unique visitor during the selected reporting period. Regardless of how many times that person returns within the reporting window, they are counted as a single visitor.

Because these metrics measure different things, Shopify Session counts and Alia Visitor counts are not expected to match and should not be compared directly.
