This SlideShare Presentation contains Many Intresting facts about Blogging and Marketing Online. One thing I was surprised by was, That people share more videos than photos but Photos get more Comments than Videos that are Shared. So if you need more Comments on your blog posts use More Image Sharing than Video sharing. Also using words like giveaway seem to get more comments. I guess this is because when people run blog contests they require a comment to enter the contest. But another problem is that Blog contests are not something that buyers are searching for.
