Apple’s been busy updating its App Store search algorithm in recent weeks, says a report in

A change made in the past few days is having a significant effect on apps and how they are ranked in search results.

The change was noticed by app marketing company MobileDevHQ. The company tracks Apple Store metrics like search rank to help developers achieve the best position within the App Store. The company claims Apple changed its search algorithm between December 11th and 12th, causing apps to jump on average 41 positions within the App Store.

This is 8 times the normal jump of 5 positions and applies to both iPhone and iPad apps.


Other interesting changes noted by TechCrunch include:

  • Per keyword, 62.8% of apps saw a ranking change of at least 5 positions. (Normally about 17% of apps for a given keyword see a ranking change of at least 5 positions per day.)
  • Per keyword, 40% of apps saw a ranking change of at least 20 positions. (Normally about 3% see a ranking change of that magnitude per day.)
  • Looking at the top 5 apps for any keyword, 31% of them changed. (Normally only about 8% change day-to-day.)

This is one of several changes Apple has made to the App Store in recent weeks. In November, Apple tweaked its search engine to correct for misspellings and other common typos.
