The global social network No. 1 will allow Google’s spiders to be launched into their Facebook mobile application for indexing content.Of course we are talking about public content: open profiles, records, groups, events, etc. Most of the information will be closed from the "spiders".
They will not find information that is available only after logging in to Facebook.

The Wall Street Journal , which is the source of this news, commented on this collaboration, “Google is working hard and making a worthy challenge for itself - search in mobile apps.” And according to Jeremy Hull, iProspect’s director of media purchases, Facebook, as a player in the search market, was a little behind, and with this collaboration, there will be a chance to reabilitate.
What gets from this Facebook?Clicking on the link from the search engine, users will remain in the application. Thus, the time spent in the application will increase significantly. For now, this will only work on Android.
What will Google get?A huge amount of information that will be available exclusively for the Google engine.
And a huge increase in users who will be shown advertising.
The Google search engine dominates the global network, but as far as advertising is concerned, here Facebook looks more confident in terms of stability.
Over the year, the share of the global mobile advertising market for Facebook fell by 0.1% (now 17.4%, according to eMarketer), while Google has a loss of as much as 4.7% (33.7% by the end of 2015). The mobile advertising market is estimated at $ 72 million, up from $ 42 million a year ago.
