Universal Language Selector/Compact Language Links/metrics/data

The usage of interlanguage links in Wikipedia is tracked in detail in a Google Spreadsheet since late May 2016 (several weeks before the deployment of Compact Language Links began). This is done to assess this feature's impact.

The raw data for these sheets is collected regularly using scripts and queries described at the page Universal Language Selector/Compact Language Links/metrics.

Status
The data is complete until December 19 2016. The data for December 2016 and early January 2017 is being updated.

 * Wikipedia % monthly
 * This is the average of clicks on interlanguage links per visit. It calculates how many user visits result in the user clicking on any of the interlanguage links for that page. The "growth" is given as the percent of the difference from June 2016. The columns after "Growth" show the same numbers, but group languages by number of pageviews. This is a key metric, showing the usage of the feature in each project, with correction for actual visits (counting only the clicks themselves would change according to season and other factors). Higher numbers mean that more readers click interlanguage links.

It calculates how many user visits result from the user clicking on an interlanguage link in another language and checks whether the feature affected the destination. The "growth" is given as the percent of the difference from June 2016. The columns after "Growth" show the same numbers, but group languages by number of pageviews. This is a key metric, showing the impact of the feature on visits to other languages, with correction for actual visits (counting only the clicks themselves would change according to season and other factors). Higher numbers mean that more people arrive to a Wikipedia in this language using an interlanguage link.
