First, I do not pretend to hold the absolute truth. This article is only a personal reflexion about Slideshare, using some of my knowledge in Webmarketing and Psychology of Influence.
As always in webmarketing , the best way to know what is the more efficient is to split-test the ideas one by one, and see if it has a positive or negative impact on conversion or click rates.
Slideshare has an hybrid business model. Their revenue comes from advertising (mostly Google Adsense I guess), but also from premium accounts as they implemented a freemium model in 2010.
My analysis will go through the two sources of revenue, and I’ll try to bring some ideas to optimize all that !
