Days before first purchase

The ‘Days before first purchase’ dimension reports the number of days that pass between the first time a visitor reaches your site and when they make a purchase. For example, if a visitor makes a purchase one day after first visiting, then any subsequent visit or event belongs to the “1 day” dimension item.

After a visitor makes their first purchase, they belong to the same dimension item for the remainder of the visitor’s cookie lifetime.

Populate this dimension with data

Adobe computes this dimension server-side from the visitor’s purchase history. There is no variable to set; it depends on the purchase event being implemented on your site.

Dimension items

Dimension items include the number of days between a visitor’s first visit to your site and their first purchase. Each number of days is a separate dimension item, with “Same day” occurring where a visitor’s first visit and their first purchase happened on the same day.
