Advice on backlinking strategy using presentations and infographics

Hello guys. I am planning on using PowerPoint presentations and infographics to build backlinks. For presentations I am familiar with SlideShare website hosting such presentations but a few things about this:

1. I heard that presentations with minimum of 4 pages must be uploaded in order for link in to function. Is this true and is it written in their TOS?

2. Are there other similar presentations websites that I should consider uploading same presentation to? Are they authoritative to be worth backlinking from? I ask because this is for local client of mine and that's why backlink is more important than views because I doubt people from respective country will look for presentation to get local service.

3. Is there information on how to organize content for presentations? Is there anything else I should be aware of?

Regarding infographics:

1. I have seen website that do not host but link back to source where infographic is located and there are websites that host infographics as well. What is the popular infographics hosting website and do they have any rules regarding backlinks i.e. like SlideShare?

2. Is there information on how to organize content for infographics? Is there anything else I should be aware of?


Thank you and have a nice day.
