The Growth team has a 2019Q2 goal of increasing the homepage discovery rate by 100%. According to our [[ https://www.mediawiki.org/wiki/Growth/Personalized_first_day/Newcomer_homepage/Measurement_and_experiment_plan#Status_of_leading_indicators | leading indicators analysis ]], without any new discovery features, the discovery rate (desktop only) in Czech Wikipedia is 30% and the discovery rate in Korean Wikipedia is 23%. Our goal is to increase that to 50-60%.
This task is about measuring the change in discovery rate, and about measuring the sources of discovery. Specifically:
* After the first set of homepage discovery features have been deployed for about two weeks, we should look at the discovery rate of newcomers who joined after those features were deployed compares to the discovery rate of newcomers from before those features were deployed. That first set of features includes:
** T222848: traffic from email confirmation success page
** T225328: link from Special:Contributions (desktop)
** T227575: link from Special:Contributions (mobile)
** T222852: discovery of homepage after account creation (desktop)
* We will want to see what percent of newcomers first visit their homepage from each of these sources, as well as from the existing discovery paths of personal tools link and tabs from the User or User Talk page.
