Days before first purchase
The 鈥楧ays before first purchase鈥� 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 鈥�1 day鈥� dimension item.
After a visitor makes their first purchase, they belong to the same dimension item for the remainder of the visitor鈥檚 cookie lifetime.
