I did not find any relevant info of how the "Views" section inside modern pages exactly work?
is it based on unique users visits? or per request visit? also how long will it take doe the Views counter to increment, is it based on the search service?
EDIT Also when i accessed the page from the Site Pages
list, and i select the modern page, i got a popup box named File Statistics
as follow:-
where it showed that i have 26 viewers with 353 views.
Also using the search api https://***.sharepoint.com/_api/search/query?querytext='ContentType:News*+path:https://***.sharepoint.com/'&selectproperties='Title,path,ViewsLifeTime,ViewsLifeTimeUniqueUsers'
(as described in @vinit kumar reply) i got a property named ViewsLifeTimeUniqueUsers
which showed the number = 99.
so in my case what do these numbers really represents "26" & "353" & "99" ?
