With the introduction of SiteCatalyst 15, DataWarehouse now includes an additional metric labeled Visits - All Visitors.
Visits - All Visitors: Includes visits of all visitors, including nonpersistent cookie visitors. This data warehouse metric is the equivalent of the reports & analytics (SiteCatalyst version 15) metric labeled Visits.
Visits: Includes only visits of persistent cookie visitors.
Visits - All Visitors higher than Visits: This result is expected. The all visitors metric includes nonpersistent cookie visitors, while the standard visits metric does not.
Visits higher than Visits - All Visitors: Not possible in reporting, as all visits are included as part of the all visitors metric.
