KentDy: on themselves, those networks won't generate more traffic. It's how you use them.
Use them wisely, and they might (never a guarantee) generate so much traffic your server won't be able to keep up.
Use them without thinking it through, and they will (this is a guarantee) impact your traffic in a very negative way.
Google+ is better than Facebook to bring more traffic. Google+ is more about sharing ideas and content. Facebook is where I see graduation pictures and wedding announcements. Facebook and Google are two completely different things.
Facebook has a lots of user base, but google plus have a lots of tech user base compared to facebook. so you just want to understand your client. according to your client you want to use your social network
you will get your terget traffic by google+, cause when you write a description about your service on google+, it will be stand on google search engine first result, if anyone search your service releted keyword.
Both the sites you have mentioned are popular and it would be better if you start using both of these platforms to promote your business. There are other social networking sites too which you should use.
I'll say it depends on your target audience. Facebook is mostly for teenagers, people between 20-30 years (at this age they are the most active users). On the other hand, people on Google+ are more there to get serious news not viral funny videos and etc.
I have found that the best thing to do if you are a newbie, is to get to know your niche and then hang out, visibly but not as a pest, in all the places that are especially good for your niche. Join groups and communities that cater to your niche, that is great both for networking and for finding potential customers, if you have a business. It takes a bit of research, but it is worth it in the end. Google Plus Hangouts are a good way to get to know (and become known) by some people in those communities. Wish you well!
It's not about the site, it's about how you manage to post there or your ability to bring more traffic. It is actually about the posts you make there or whatever you do for bringing more traffic. All you have to do is to post the quality work and something that people do like.
