Adding full length articles on Google plus will not give you that impact. But short paragraphs with good info get shared often. Photos, links that go with that make it more sharable.
Full articles can be divided into different points and can be posted one by one as a special series...
Eg: Internet Marketing Tip #1 or anything similar...
On Google plus(or any social media) no one is going to read an entire article, line by line..so make it short and with bullet points.
