Apple has recently opened new App Stores in 13 countries, pushing the total number of App Stores to a staggering 90. Starting today, ranks and reviews from all new App Stores will be tracked and reported. The new App Stores include the following countries and are already in full swing:
Earlier today we’ve discovered that Apple has published some incomplete daily and/or weekly reports for 2/14 and 2/8 – 2/14 to iTunes Connect. It seems that these reports have since been removed from iTunes Connect and are being republished. Not all reports were incomplete, so you may not be affected by this. If the daily/weekly report you’ve received earlier today looks incorrect this is probably the reason. To ensure data accuracy we’ve removed all automatically imported daily and weekly reports and restarted the import again. We’ve also re-sent both daily and weekly email reports with “Updated” in the subject so you can differentiate between the current and possibly incomplete ones. Members with auto import turned off can re-import these reports by removing them from the archive and then uploading them directly or starting a sync with iTunes Connect. We’ll continue to import throughout the day to catch reports that have not been republished. Feel free to contact us directly if you have any other questions or need further assistance. The appFigures platform is growing, and so it our team. We’re on the lookout for a talented web developer in the New York City area to join us. Click here for more details. We couldn’t help but notice our community being all a-twitter about huge, unexpected rank changes in the last two days. We thought we’d break out the old calculator and examine it a little bit. As you know, appFigures tracks top-200 ranks in App Stores around the world. We took this data and looked at each app’s changes by comparing the hourly change of each app and taking the largest hourly move per day. We added up all the apps that had a big change > 50 (up or down) and compared those numbers to the same days of last week. The goal was to get a picture of high-magnitude changes in rank, the sort that would seem unexpected. The numbers spoke and told us that something was not right. Tuesday was slower than usual… Wednesday, and Thursday were crazy! Let’s get numeric: During a normal day, 5.77% of apps experience an hourly rank change of more than 50 places (up or down). On Wednesday, that number shot up to over 70%, indicating that it was a particularly volatile day in terms of high-magnitude hourly moves. Thursday experienced similar churn, with nearly 50% of apps experiencing these high-magnitude changes. Here’s an overview of the last 30 days on the App Store. Look at that NBA-level jump…
And here’s a direct comparison to last week:
Then we dove a little deeper into the nature of the changes, taking not only hourly rank movements of 50+, but breaking them down into four groups: 0-50, 51-100, 101-150, and 151+ places. On normal days, 94% of apps see no hourly rank change greater than 50 places. A bit less than 2% see a shift of 51-100 places, and the same for 101-150 and 150+. On Wednesday and Thursday, only about 40% of stayed within 50 places, with around 20% seeing a change of 51-100, and likewise for 101-150 and 150+ places. Take a look at the breakdown: This is what a normal day on the App Store looks like
This is what Wednesday and Thursday looked like
We were puzzled as to why the big movers were distributed relatively uniformly (in that the percent moving 51-100 places ~ 101-150 places ~ 150+ places), rather than showing a more normal distribution, but that’s for another day. Another peculiarity we found on 2/3 and 2/4 was the average highest hourly rank change per app. That number was consistent around -8 places up until 2/2. On Wednesday and Thursday it jumped dramatically to around +25 places each day. So, though the app store has shown big swings on those two days, an app’s biggest hourly swing is on average 25 places up. Well that’s it for now, we’ll have some more analysis coming soon. |
