TechCrunch reports that a week or so ago, Apple updated their App Store search algorithm, and the rankings of many apps for many keywords have changed.
Sarah Perez said, “[A]round a week ago, it appears that Apple yet again tweaked the way its rankings worked, but this time around, the changes have only impacted a subset of iPad app developers in the US App Store.”
My company has several apps, and I noticed ranking changes, some positive and some negative, for our key apps in both iPhone and iPad App Store searches.
The TechCrunch story shared several charts and examples of tools showing ranking changes across apps as large as Facebook, and also to other smaller apps.
Here is one example from the story:
Facebook’s iPad app offers a good example of the change, as its app moved from a #2 position in “Social Networking” and a #7 ranking “Overall” the day before, down to #4 and #24, respectively, on Friday, and then it crashed to #38 in “Social Networking” and a practically invisible #858 “Overall” by Monday.
The app’s download ranking has since begun climbing back up, reaching again #2 in “Social Networking” and #9 “Overall” by mid-week.
