All search page rank
The 'All search page rank' dimension provides insight on which page of search results a visitor clicked through to your site. For example, if your site appears on the second page of a search engine's search results, the dimension value for this variable is "Search Page 2".
Populate this dimension with data
Getting this dimension to work only requires that your report suite have Internal URL filters set up correctly. AppMeasurement automatically populates this dimension without any implementation code changes.
If a visitor clicks through to your site from a search engine, this dimension's value is "Search Page" followed by the page number they clicked through on. If a hit does not originate from a search engine, this dimension's value is "Unspecified".
