In 2014, it was destined to be the time when giants snapped up the mobile Internet.

    At home, Ali and Tencent's battle for mobile payments is in full swing; Facebook's $19 billion snapp-up of WhatsApp from Google has once again highlighted the importance of "mobile." One is the social networking giant, the other is the search engine boss, does not seem to be in a field, but those are advertising as the main source of revenue. In today's increasingly mobile, began to play a mobile abacon.

    Smartphone users spend about 80% of their time on apps, while only 20% of their time on search engines. Mobility first disrupted user habits and then changed the advertising landscape.

    In mobile advertising, Facebook has long had an action - advertisers can buy sponsored content from mobile news feeds. This is great news for smartphone app developers. In other words, just give a link to a potential user's phone and your app downloads may skyrocket. Faced with this situation, Google is also starting to fight back on the mobile side, and in 12 years last year, android version of Google Search expanded its search capabilities into the app.

    Google is using Deep Linking as technical support for the App Index. The technology will provide unique links to different sections of the app that resemble "URLs." Once the user clicks on the link, they can jump directly into the app.

    Why use Deep Link? Although "search" is the information portal on the web, the mobile world is not. Google has long used "spiders" to crawl critical information within web pages, but many developers don't include links in their products because of barriers between apps; "Spiders" are limited in the mobile world, and Google hopes to get app developers to proactively submit content crawl applications in new ways.

    Google's advertising model on the web has long been to jump to the relevant advertiser's page by clicking on a link. On the mobile side, Google also wants to continue this approach by indexing apps in Google searches on smartphones. Unlike jumping a web page, users can jump directly to the app with a click. However, the app must be pre-installed on your phone. When it comes to apps, Google already has support from Wikipedia, travel site Expedia, restaurant guide Open Table, and movie database IMDb. That is, when people using the Android tracker search for movie information using Google, they can see a link to the imDb app's internal page. Given the "small and beautiful" size of the smartphone screen, linking to an app is clearly a much better experience than jumping directly to a web page.

    Similarly, baidu and pea pods in China have also begun the "in-app search" attempt, accepted Alibaba investment in the app search engine Quixey will also start to explore this aspect.

    Lawrence Chang, product manager for Google App Search, says Google currently only offers content links to Android apps, but expects the service to also be compatible with iPhones.

    In addition, Google has not sold ads on one side of such links. However, "Adwords in deep links is a huge business and I believe advertising will come soon." Says John Milinovich, founder of URX, a mobile advertising agency.
