Are more links from the 'same' sites helpful for your website in terms of links for SEO? 1 outsourcer is going to share some PDF to various sites for me and said ...more links from the same sites are helpful ONLY if you provide quality PDF documents.
What is the score here... if you provide decent content will more links from the same sites like SlideShare help SEO? Should the content be original or can it be an article previously posted to my blog for example?
Should I target KW's on my website or different ones aswell?
How many words would you suggest on this PDF?
I have heard these sites can really help for links and traffic so just wanted to find out how other people get the most from doc sharing.
