Six Ideas for Finding New Sales Leads Don't overlook these unexpected online opportunities for prospects.

Sometimes in life, you kick over a rock and find a thriving colony of activity. So, too, in business. With so many tools, niches, sites, apps and platforms to look for and nurture customers, it's easy to overlook less obvious opportunities. Here are some to try.

1. SlideShare
SlideShare.net offers the ability to upload and share presentations, e-books, PDFs and webinars. It isn't exactly a backwater, but it's a bit of an undervalued spot. With 60 million visitors per month and 130 million page views, it's the world's largest professional content-sharing community and one of the top 200 sites on the web.

SlideShare is also one of the only high-traffic platforms that integrates organic and near-seamless lead generation. The network's LeadShare service requires viewers to fill out a contact form in exchange for downloading a presentation or PDF, and it encourages viewers to contact the business for additional information at various points throughout a presentation. Of course, this feature comes at a price: To enable lead-capture, you'll have to spring for a Pro SlideShare membership, which can cost $19 to $249 per month.
