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 "Metric" options?

• Pageviews is the total number of pageviews the project received.
• Unique devices is the number of unique devices that visited the site.
• Pagecounts (legacy) refers to the older, and less reliable way counting pageviews. This data is available from December 2007 to August 2016.

Are pageviews by the same user counted every time?

Yes. Every time you load a page, a pageview is registered, even if you created the page. You can learn more about the pageview definition at meta:Research:Page view.

What are the dots next to the date labels?

This indicates the first day of the week. Pageviews tend to be low during the weekends, so this indicator can give perspective to the seven-day pattern.

How can I change the chart type?

Click "Chart type" to choose amongst 6 different types. The app will remember your preference. By default, the application will show a bar chart when viewing data for a single page, and a line chart for multiple pages. Note that the pie, doughnut and polar area charts can only show data for total number of views within the daterange.

I want to see the top viewed pages within a date range
