AppCod.esA different approach the popularity by AppCod.es how many people downloaded top apps found for a given search query (using Xyologic data)
AppCod.esWe’re not perfect• some of our data sources are >1 month old, so if a query is very fresh, we’ll display a lower rank• some of the queries are missing from the database. if we show “-”, it probably means the query is unpopular, but in rare cases we just have no data• a difference of 20 in hotness may be a statistical error (i.e. if one phrase is 40, and another is 50, we really don’t know which one is more popular)
AppCod.esKeep in mind - the phrase popularity is still an experimental feature - it’s better to rank top5 in the not-so-popular phrases, than rank top15 in the most popular ones - iterate, iterate, iterate. with every update remove the worst performing phrases and try some new ones. if it’s possible, ask users how they ﬁnd your app.
