Mobile Beta/Watchlist/Logging

This page presents data from the logging of watchlist star taps on the Wikimedia mobile web.

Background
We were interested to see how many users would use the watchlist star feature if we presented it on the mobile web. We first built a prototype watchlist star on the beta mobile site, then promoted the feature to the full version of the Wikimedia mobile web. Unlike on desktop, the star is displayed to all users, registered and unregistered. The behavior is the same as the desktop for registered users, but unregistered users receive a call to action to log in or sign up for a Wikipedia account to use the feature.

First 24 hours
In the first 24 hours since deployment:


 * 457 unique registered users used the watchlist star to watch or unwatch at least one article
 * These users performed a total of 1,026 watch actions and 619 unwatch actions
 * 36 unwatches came from the watchlist view, and the rest directly from articles
 * 95,560 watchlist star taps came from unregistered users (raw count, not deduped by user)
 * 526 new accounts were registered via the watchlist star CTA for unregistered users (0.6 % conversion rate assuming most taps came from unique unregistered users)
 * 92 of those users went on to use the star again at least once in this 24 hour period
