SlideShare makes it easy for you to share and discover presentations, documents, and even videos. It’s free for most users but offers advanced features for those willing to pay for a pro account. SlideShare is a great platform for sharing your expertise and getting feedback on your presentations. Like photo and video sharing sites, you can tag your presentations with keywords to make it easy for users to find your content by category. You can also link your presentations to your website, which will help customers find you and give your website a nice SEO boost.
