Why can't I view data older than July 2015?
The Wikimedia pageviews API was introduced in August 2015 and has backfilled data to July 2015. You will have to rely on other tools such as stats.grok.se to view data older than this. Whether or not they work is unfortunately outside the scope of this tool, and beyond the control of the maintainers.
Why can't I view data for today's date?
The Wikimedia pageviews API generally takes a full 24 hours to populate, sometimes longer. In some situations you may see data missing for yesterday's date as well, which will be left blank rather than showing a count of zero views.
Why do some pages have unusually high pageviews?
If you see an inexplicable spike in pageviews, especially if it is only on specific days, it may be false traffic from an automated program. One tactic to identify bot-inflated traffic is to compare desktop views with mobile views. First see which agents are most popular on your project for all articles, and use that as a basis for comparison. For instance on the English Wikipedia mobile web views should be comparable if not higher than desktop, so if mobile web views are very low, it might be false traffic.
If you are unable to conclude it is false traffic, you can request an investigation to be done by filing a ticket on Phabricator. These pageviews anomalies are common and tedious to investigate, so do not expect a timely response.
What are the "Agents"?
- User includes all people who view a page. Editors, anonymous editors, and our readers.
- Spider includes search engine "web crawlers" like Google that read pages for the purposes of improving search results. Pages can receive significant views from web crawlers, which is why by default the tool shows data only from users.
- Automated includes automated programs that are not search engine crawlers.
