Google Analytics uses the following formulas to calculate the metrics used in internal site search reports:
• Visits with Search = The number of visits that used your site's search function at least once.
• Percentage of visits that used internal search = Visits with Search/Total Visits
• Total Unique Searches = The total number of times that your site search was used. This excludes multiple searches on the same keyword during the same visit.
• Results Page Views/Search = Page Views of search result pages/Total Unique Searches
• Search Exits = The number of searches a visitor made immediately before leaving the site.
• Percentage of Search Exits = Search Exits/Visits with Search
• Search Refinements = The number of times that a visitor searched again immediately after performing a search.
• Percentage Search Refinements = The percentage of searches that resulted in a search refinement. Calculated as Search Refinements/Page Views of search result pages.
• Time after Search = The average amount of time that visitors spend on your site after performing a search. This is calculated as Sum of all "search_duration" across all searches/("search_transitions" + 1)
• Search Depth = The average number of pages that visitors viewed after performing a search. This is calculated as Sum of all "search_depth" across all searches/("search_transitions" + 1) Sample Calculations
