As you know, we track hourly rank changes from all App Stores around the globe. On Wednesday we noticed odd behavior from every app store—suddenly they were all stuck. For eight hours 99% of apps did not budge. We were just about to blog about it and then movement resumed. A fluke, we thought, wandering away from the single legal pad we’d all been crammed around. But then it happened again! The U.S. App Store’s been frozen for the last 24+ hours!
Let’s look at the numbers:
On average, 65-95% of apps move in the U.S. store every hour. Actual increases and decreases in rank depend mostly on the time of day, with midday (1pm – 4pm) seeing the heaviest movements. This is true for both iPhone and iPad apps.
Since 4am yesterday the percentage of apps jockeying for rank has dropped dramatically to just 0.5% – 4.5%. What’s also interesting is that of the small percentage of apps that did move, the majority weren’t in the top 100, and they were restricted to just five categories, while every other category remained motionless. Weird.
We like visuals. Here’s a breakdown of percentage changes within the last 14 hours:
A snapshot of approximately the past 30 hours:
Is Apple changing its ranking algorithm? Are the current ranks being pulled from an old cache while Apple tries to fix a problem…and is Apple having the same difficulties they had a year ago?
Assuming we find out what’s behind Apple’s strange behavior, you’ll be the first to know. It’s days like this I’m glad we keep a private investigator on staff. Kind of.
