Linden Lab Official:What is traffic (formerly known as dwell)?
Traffic is a numerical metric calculated for every parcel of land inworld. This score can be summarized as "the cumulative minutes spent on the parcel by all visitors to the parcel within the previous day, SLT." It's calculated by taking the total seconds spent on the parcel, dividing by 60, and rounding to the nearest whole minute. For example, if your parcel has a cumulative seconds total of 121s over the course of a day, your score will be 2.
|Note: Note: There are currently no official Traffic incentive programs in place; owners of popular parcels do not receive any Linden dollar bonuses based on their Traffic scores.|
Where can I find a parcel's Traffic score?
You can view Traffic points on the General tab of the About Land window for each parcel.
Traffic is one of several factors included when calculating search results. For more information on inworld search and how it works, see the Search FAQ. For further historical context, please see the Resident-maintained "Traffic" in the Second Life History Wiki.
