Hi Chenqi,

You can find out more about what constitutes a pageview in its Metawiki article:

https://meta.wikimedia.org/wiki/Research:Page_view#Definition

As you can see, one of the conditions is whether the request being examined is a preview or not, in which case it is not counted as a page view. Hope this helps!

Hi everyone,

I am trying to better understand the pageview data. I have a quick question. I apologize if the question has been asked or it is so naive.

If the web browser prefetches a Wikipedia page, does it count as one pageview in the pageview data? By "prefetching", I meant X's Wikipedia page shows up in the search results and the browser prefetches/preloads the search results but I do not click on X's Wikipedia page. If so, the pageview data seem to over-count the number of visits to X's Wikipedia page.

Thanks in advance for any insight.
