I will give you a simple little trick when you want to promote your webpage into social media such as Facebook and LinkedIn. Just a few days ago LinkedIn copied the thumbnail function in the newsfeed from Facebook. When you post a link both Facebook and LinkedIn will bring one of the images (if there are any) from the webpage you linked to. If you think about this when you build your webpage and make a picture that is optimized for this purpose it will be much more attractive to both share and click the link. You can se what I mean below. The thumbnail will also come up in the newsfeed when anyone likes your link which makes this method even more worth full.
