App analytics provider App Annie launched new services to help app publishers market their titles more effectively in Apple’s App Store, Google Play and Amazon Appstore.

App Annie already helps app publishers with ‘organic app discovery’, by tracking the ranking of titles in app store charts and featured placements.

In addition, app publishers now have access to keyword search data on the App Annie platform, which allows them to track the search ranking of an app by keywords.

Data includes keyword top charts and top keywords by app data, which publishers can use to adjust metadata associated with their apps to optimise their visibility in app store search.

Research by analytics firm Forrester, cited by App Annie, found that 63 per cent of iOS users discover apps by searching in the App Store while 58 per cent of Google Play users discover apps through search.

App Annie is also providing help with paid app discovery through its Advertising Analytics tool which aggregates mobile advertising data from more than 20 ad platforms, including Admob, Ad Colony, InMobi and RevMob.

Publishers can use the tool – which was previously in beta form — to view mobile ad spend and revenue alongside app downloads and revenue, giving them a complete view of their business.

The additional data should allow publishers to get a better understanding of user acquisition and paid advertising strategies.

App Annie CEO Bertrand Schmitt said advertising technologies are “greatly fragmented and difficult to navigate” so publishers will benefit from being able to analyse their advertising data next to app store data.
