Facebook and twitter are the best way to get started. Create a profile and start tweeting on twitter with attractive links of your blog/site. Make sure you don't post number of tweets at the same time or else you will be consider as spam. In facebook create a group of your site/blog and invite your friends to join it. Share update of your blog. This way you will get traffic.
Interact with people. That's the best way to see tons of traffic and success from your social media efforts. It really is that easy
Exactly what he said. Rather than trying to sell on Social networks let it be a channel to communicate concerns with customers. I think that's what more important.
Yes, Social network not generate targeted traffic, this traffic not help to earn good income. but all traffic are not bed, some traffic do help to incrise business.
I found this Digg guide useful but is hard to on the homepage: http://www.bestblogs.asia/getting-dugg-guide.php
i would create a sharelinks.co page You can put link to all of your social networks on a simple clean page. You can then share that page on Facebook. It will spread more than just a single social network. It will spread every link on the page with your facebook friends. You (or your fans) can also share it to Twitter, MySpace, StumbleUpon, Digg, Delicious and even e.mail it. It spreads your whole network so much faster than just sharing a single page. you can visit sharelinks.co/share to see what a page looks like and if you want you can even share it to see how the share widget works when spreading your whole network. It's probably one of the greatest tools on the internet.
