Remember that using LinkedIn for site promotion requires you to do the following:
1. Insert URL on your personal profile
2. Create a business page with the business URL
3. Create event with the business URL (only if you have an event - if its only online).
4. Join and participant in groups and plug your URL
LinkedIn is a great place where you can meet so many people who belong in the similar group. Share your ideas and thoughts with them. It's a great place to highlight your business and knowledge over there. You can recommend any people over there, add people to your network.
I am just having profile in LinkedIn? But How to use Linked In for my site promotion?
Here's an excellent way to use LinkedIn Answers for blog content:
Once you have a general idea for a new post (especially one that offers an opinion on something), ask related questions via LI Answers. So, for instance, when I was writing a post about if there is truly a "social media capital", I asked people to give their take. I clarified the question (as a kind of disclaimer) to include the fact that I was going to re-post select answers to my blog. I got a ton of responses, and the best answers actually challenged the idea of a physical capital of social media.
I basically re-posted the best asnwers, responded and expanded on them, and then provided my take. It was one of my better posts, and this is the great part: After I notified everyone that they "made the cut", they were all happy about it, sharing the post across their networks.
Linkedin is another way to do social networking, like facebook but this is more on business type unlike with facebook you will interact with different kinds of people online. I will try linkedin as well...
