You can search about people, products, companies in these sites. Facebook is taking the services of Bing for default search results,so in facebook you can get everything. So why people will use Google, if they get everything in facebook?

Facebook is a social media site, where people are spending their time to interact friends, to check the status or updates of their friends, relatives etc. And searches in Facebook are more personalize. In Facebook you can get the recommendation of the people about particular product, services. Like you can know how is the food of the restaurants or how is the recent released movie? In social media sites People talk about their experience or opinion about product or services.
But what you will do when you want to go a restaurant or coffee house with your girlfriend or you want to find a multiplex in your near surrounding. In order to get these information you can't wait on facebook and wait for some one answer.
So best option is to use Google Sitemap, you will not only get the information but you can also see the path to reach there. Below i have discussed some of the feature, services of Google which show Facebook is not the competitor of Google
As i discuss above in Google you can find instant search with maps, moreover now Google is providing the Real Time Search option, means you can find what people are saying about your search. You can see what someone had said about your search one second, 1 min ago in Twitter as well as in Facebook. Yes, Google is showing the latest search results from Twitter and Facebook, both sites had done deal with Google to show their data in search results.
I think for videos views, videos search no one social media sites can beat You Tube, just come after Facebook in daily traffic. You Tube is Google owned website. Google is trying to make videos more personal and doing lots of research to make videos more better.
Google Comments on Competitors
On the competition from Facebook, Twitter Google said, "we are not worry about our competition. We are focusing on creating wonderful products, which people are going to love. We don't believe in wasting our time on what our competitor is doing and how we can stop him? If we bring good and useful products then our task had done."
Also why people forget Google is not a web site, in Google basket they have everything for Internet user. Google have more than 100 internet applications, products and millions of people are using them. And moreover 100 of more applications or products Google is planning to launch. Some of popular products,applications of Google are :
Androids mobile phone, Gmail, Google Chrome, Google documents, Google Buzz, You Tube, Google Voice, Blog spot, Google Places, Google Picassa, Google wave, Google analytic, Google ad words etc.
Google are planning to bring Google TV, Cloud Computing and many more web application about which only Google know.
