I Think, All Social Media are Best for Social Media Marketing. But Today's mostly use in social media Facebook, Twitter, Google+, Pinterest, tumbler, stumbleupon.... its most use in today.

It's totally depend upon what type of your business is or Is your audience professionals or nonprofessionals. I would suggest for professionals audience target Twitter, LinkedIn, Quora and Xing and for nonprofessionals use Facebook, Twitter, Quora, Instagram etc.

Twitter and facebook

1. Facebook
2: Twitter
3. LinkedIn
4. Reddit
5. Pinterest
6. Stumbleupon
7. Digg etc.

Facebook, Twitter

Facebook & Twitter both are the best social media platform.

Reddit and quora can be counted as the best social media to drive the traffic for website. But there are other which are common like Facebook, twitter, linked in, etc.

Only Paid Social media is fruitful current time ....

I prefer Linkedin, Reddit, and Tumblr.
