If your Google+ account has lots of followers then they will be able to see what you Google +'ed. They could check this out and drive traffic to your articles.
Yes I think that if you can promote your content on multiple social networks e.g. google+, twitter, reddit etc. it should help to get your content talked about.
I think you'd better not put these articles directly if your account is a personal one. Your follower may not like such a kind of promotion.
It depends upon the type of followers you have. If your articles relate to them then there are chances that they will like them. Otherwise its of no use.
try to develop your Google+ page with valuable contents and try to add more friends in circle. Still the platform is small but it has grown in a tremendous rate.
i think google + very use ful to get page rank to your website.iam add g+ 24 and get 1 pr this month update.my site www.hollywood-desktop-backgrounds.blogspot.com
I +1 all of my articles and share them with the circle appropriate to the niche that the article relates too.
I post articles on my Google+ for my own company but that is because I use Google+ solely for business. I would advise having a comprehensive social media campaign, so anything you share on google+ can also be shared on Facebook, Twitter, Linkedin, etc. It will increase traffic to your website (as long as the content is unique/interesting!)
If you have a very good and valuable contents on your site I think you are definitely going to have good amount of google +
google+ is one of the best social media network and this network is the best source for getting more traffic.so i did not want to miss the chance any more.
