Visitors

All methods Adobe uses to identify unique visitors (custom visitor ID, Experience Cloud ID service, etc.) are all ultimately calculated as a value in post_visid_high and post_visid_low. The concatenation of these two columns can be used as the standard of identifying unique visitors regardless of how they were identified as a unique visitor. If you would like to understand which method Adobe used to identify a unique visitor, use the column post_visid_type.

  1. Concatenate post_visid_high and post_visid_low.
  2. Count the unique number of values.
  1. Count the number of rows where:

    • post_page_event = 100 for custom links
    • post_page_event = 101 for download links
    • post_page_event = 102 for exit links

Custom events

All metrics are counted in the post_event_list column as comma-delimited integers. Use event.tsv to match numeric values with the desired event. For example, post_event_list = 1,200 indicates that the hit contained a purchase event and custom event 1.

  1. Count the number of times the event lookup value appears in post_event_list.

Time spent

Hits must first be grouped by visit, then ordered according to the hit number within the visit.

  1. Concatenate post_visid_high, post_visid_low, visit_num, and visit_start_time_gmt.
  2. Sort by this concatenated value, then apply a secondary sort by visit_page_num.
  3. If a hit is not the last one in a visit, subtract the post_cust_hit_time value from the subsequent hit’s post_cust_hit_time value.
  4. This number is the amount of time spent (in seconds) for the hit. Filters can be applied to focus on dimension items or events.
