I am software marketing consultant. I have a question on best practice.

It is my understanding that to get the full benefit of Inbound Marketing, in addition to blogging and SEO, social media must be leveraged.

What are some of the best practices for a product (if it is software for non-consumer applications such as intellectual property blocks used in IC design) that is not a market leader?

Thank you.

Are there any good free tools that I can use to collect leads online for a small business? 

My company's starting to use webinars for lead generation. What's the best service to use?
