Welcome to WebmasterWorld Guest from 220.127.116.11
I've been trying to learn the difference between "uniqe pageviews" and visits when it comes down to an unique URL.
Google says that: "A unique page view represents the number of sessions during which that page was viewed one or more times." (http://adwords.google.co.uk/support/bin/answer.py?answer=57164)
In my understanding, for an unique URL, the number of pageviews should be equal to the number of visits. However, in my case it is always (meaning - for each unique URL) different. The number of unique pageviews is bigger than the number of unique pageviews.
Could someone explain it to me? I have reported it to Google, got some feedback (ther are checking on it), yet they haven't come with an answer yet.
Perhaps you might have an idea for this situation.
Thanks in advance.
If you could correct it and explain it more it would be helpful. Are you saying that if you sum up all the numbers of unique pageviews you get more than the total number of visits to your site?
If so, that's correct. It will always be more, except in the special case of each visit containing only one page view.
Google's term "unique pageview" is the same as other analytics' programs term "visits to this page." A visit that saw Page A five times will be recorded as 5 views for Page A and one unique pageview for Page A.
If two visits happened, each viewing Page A and Page B twice, Page A will have four views and two unique pageviews, and Page B will have four views and two unique pageviews. Add them together and you'd get 8 views (correct) and four unique pageviews (wrong - there were only 2 visits).
Does that help or did I miss the point?
I'd like to stress that I analyzed AN UNIQUE URL, not the whole site.
The number of unique pageviews is from Top Content / chosen URL / Content Detail, and the number of visits - from Top Content / chosen URL / Segment - Source.
For a longer period of time the data from Segment - Source section is always "based on sampled data", yet the suggesteg +/- percentages for different sources won't amount to the whole dicrepancy.
For example - for a given URL, I get:
80,118 Unique Views
And 38,582 Visits from the Segment - Source report.
So - you missed my point slightly :)
this must be the reason why you're seeing different data for visits and pageviews.
i saw a couple of analytics aco#*$! and confirmed that in all of them the pageviews and unique views have different numbers. this is my understanding:
i am not sure how the differentiation is made. but, i guess if the user is simply hitting the back button "it is not, unique." on the other hand, if the user is closing the browser and opening it again -before coming to your page; or maybe following a unique link in the same browser session to reach that page a second time, "it is unique."
i know this is not the complete explanation. but, i am sure i am pretty close. if you notice, the "unique view" numbers are pretty close to your "page views" number.
Closing browser or using a unique link should not trigger a new session. And if there is a new session, a visit to a given url should be also considered another uniqe pageview (since it is a new session).
I am looking at a similar problem with HBX.
I need to find out why there is a difference between page views and page visits, when the same page is accessed.
E.g. for one, one page article on a website, I get 361 page views and 254 visits.
It must be something to do with the way these are tracked by HBX.
