Google built its search business on open web. However smart phone users spend most of their time in mobile apps. Google search has been given speed and intelligence over years. It is just 17 years old. But it has a huge impact. In the cell phone using world, it faces competition from start ups funded by venture capitalists. Google can, however, buy any start up with $ 65 billion in its bank account. The interesting part is that Apple has entered the search business. Its iOs software allows users the searches of music, apps and services, bypassing Google. Google too runs the world’s largest mobile operating system — Ardroid. It makes billions of dollars a year selling apps through Google Play Store. However, the apps do dilute the position in search. E-marketer, a research firm, puts Google’s search revenue at 68 per cent of mobile search revenue, but it has come down from 81 per cent share it had in 2012. This has happened as apps occupy more time of people. And on mobiles, the difference is that people avoid going to the search box as the first resort. Smart watches is not a good option for searches. Google updates ranking alogorithms so that web-sites that are deemed to be mobile unfriendly fall in search rankings. Google built products. Like Knowledge Graph which provides answers to queries. It reinforces voice search. Another ambitions project of Google is Now On Tap to facilitate searches on mobiles. Just tap on the home screen button to search, rather than cutting and pasting or typing words in the search box. The original search alogrithms developed by founder Larry Page and Sergey Brin are constantly being re-written. Google can now answer questions of mobile voice searches. Search results come with tappable actions.
