What's the point in posting to Facebook, Twitter and G+ when you don't have a following? Either work on building your audience on those platforms, or work on your site itself first. If a tree falls in the woods and so on...
Your featured images are are no bueno, they don't make me want to click on any of your articles and the sizing of them is messed up so they look all distorted on your homepage.
You need a better logo.
You need to finish off the footer on your site, right now it just has the words "Google Plus".
I wouldn't put the disclosure right in the sidebar..
Look at all the white space on your homepage that's wasted because of that logo taking up a bunch of space... You'd be better off just having the title of your site in normal text.
None of the titles of your posts inspire me to want to click and read them.
Take a look at some of the more popular sites in your niche, then look at yours, then look at me, now I'm on a horse, then look back at your website and hopefully you'll be able to see past the "Hey I made this!!" pride and to look at it objectively to see that it doesn't look like other sites.
What's with the bright red?
There's a lot to work on before you start worrying about traffic. Hopefully you take my criticism constructively. How in the hell are you going to call that an authority site? Does "authority" literally mean anything at all these days? It's offensive to people who have worked years to learn how to make great authority sites to call that one.
Having said that.. it's not hopeless.
Your site definitely needs some TLC tho. Once it doesn't look really bad, I would start thinking about building up an audience and sending traffic to it. If you're just going through the motions of posting to Twitter and FB etc without reaching an audience or getting traffic then that's the definition of insanity. WTF makes you feel entitled to get traffic when your titles and featured images aren't compelling, and when your site isn't even done? If it was that easy, there wouldn't be any threads like this...
