Being on LinkedIn, is a good idea ... but developing your business with it: it's better
I assume you have an activity (company ...) to develop.
You have registered (personally) on LinkedIn: it's good to find lost contacts and for your CV. But for your company, you must create a company page: it's the company profile.
Then, you should add a button to give your blogs/web sites readers an incentive to follow your company. LinkedIn gives you a hand with that. And ask your LinkedIn contacts to click on it to raise your followers number.
At last you may want to read LinkedInI advices to improve traffic on your page.
Happy networking on LinkedIn !
