Domain authority not showing on root domain?

[askotzko]

I was going through our site earlier w/ the mozBar (still learning the tools, new here) and saw the attached image. There were far more links to the subdomain (#s on the left) than the root domain (#s on right).

This is strange to me, because we are not using any subdomains. All links point to either our root domain or subfolders off our root domain.

Is this hurting our ranking for the root domain? Not sure what's up with this.

subdomain = www.

So what you're probably seeing is a lot of your domains are pointing to www.domain.com rather than domain.com

That makes sense. So is that hurting/helping our SEO? We have a 301 redirect in place on the www. so I imagine it shouldn't be big deal.
