Another key feature is Hangouts, which is a free video conferencing service for up to 10 people. Hangouts allow users to chat through the Google+ website or mobile app, with the service supporting many apps like YouTube and Google Docs.
Other features of Google+ include events, location tagging and multi-person instant messaging.
Although Google+ claims to have millions of users, it still lags behind competitors such as Facebook. However, it is hard to assess Google+ growth as its definition has changed – at first, Google defined the service as a social network, before later describing it as ‘a social layer across all of Google’s services’.
