I have 2 linking root domains on my URL. But I don't get the whole Root domain thing. So I don't understand how I can improve it?

I have 2 linking root domains on my URL. But I don't get the whole Root domain thing. So I don't understand how I can improve it?

I copy and pasted this, from my Links page in my campaign because I can't seem to grasp what a root domain is:

'A higher number of good quality linking root domains improves a page's ranking potential'.

Can some one explain to me what this is. As simply as possible.

Here's my site www.Thumannagency.com

Thanks in advance:)

Matt, You're a life saver. I get it now:) Thank you so very much.

Let's say Moz links to your site 5 times. That's 5 links but 1 "root domain" (moz.com)

Now, NY Times links to you ... 1000 times. That's 1005 links and 2 "root domains" - moz.com and nytimes.com

A root domain is just a domain that links to you - the first link from each domain seems to count more so the more root domains you have is better (rather than the number of backlinks total.)

To put it another way, you'd rather have 20 backlinks from 20 separate root domains than you would to have a sitewide link from 1 domain even though that may be thousands of backlinks.

Rand covers this all just a little here: https://moz.com/blog/understanding-root-domains-subdomains-vs-subfolders-microsites
