To put it short, Facebook for personal and LinkedIn for professional affairs.
That said, Facebook doesn't offer as much as it used to. Nowadays I mainly use it only for chatting with friends. I'd delete my profile if I could easily chat with friends elsewhere. Too bad I can't so I "have" to remain in Facebook.
LinkedIn is a great tool to give you some credibility. For example, I frequently sell domains to end users. I contact them directly by email. At the end of the sales letter (which is customized yet very short), I put my signature with full name, title, company address and phone number. I believe recipients now and then google the sender's (my) name, to see what comes up. Among the top results is my LinkedIn profile. I've put a photo & education and job history of myself there. I've written what I'm currently doing. I also have listed my email
and even phone number (only for logged in users, though). I have some connections as well. This hopefully tells people I'm conducting legitimate business and not trying to scam them.
In other words, having a completed LinkedIn profile can boost your sales. People trust LinkedIn, moreover they trust a person who tells something about himself. And shows his photo. And has some (LinkedIn) connections. You obviously know yourself you are not a fraud - now show it to other people by having a great LinkedIn profile!
I like Face Book more than any other social platforms.
Face Book is used by 1 billion people across the globe and no other social media site is that big. You can do a lot on Face Book to driver traffic to your website.
Both Facebook and Twitter are powerful social networking sites but to me it is the sheer reach of Facebook that makes it a better alternative. There are many who do not even know the existence of Twitter or are not interested in it. The various aspects of Facebook like note creation or creation of fan pages make it a much more appealing social networking site, undoubtedly.
People who actually active with digital marketing is give more preference to Social Media. Because social media is very powerful tool. Through social media your site is get almost a huge amount of traffic if it's done properly. I prefer Facebook more in compare to other social networking sites.
For me Facebook and G+ is best. These bot the website have high user traffic and they help to promote business and help to stay update with Social news. These is also good for business promotion.we sell our products online with these website and help to improve business.
