I think your friend might be confused. My sites usually get updated data once per day.
i am using google analytics for my 6 sites.
but they update data one time in a day.
but my friend say that he can saw update everytime.
can anybody tell me what happen with my account?
My sites get updated constantly throughout the day; definitely not just once.
Not sure what is wrong with your account though.
That's the default view jakki, you must click on the date that's on your top-right and then select the dates interval you want to work with.
