How is Moz's DA score so high?

[WickVideo]

Obviously they make the tool that measures this, but is their own score inflated because of this? I know DA isn't strictly a measure of popularity, but Moz's own score seems a little _too _high compared to some other sites...

• 92 - Moz.com
• 90 - Salesforce.com
• 87 - Airbnb.com
• 84 - Priceline.com
• 83 - Squarespace.com

Can someone shed some light on how DA is actually measured?

"I think" a condition related to the quality of incoming backlinks to the site.

Hi there

First, here is where you can read about how Domain Authority is calculated.

Second, Moz is a highly respected business/website with tons of great backlinks and mentions all over the web - I highly doubt they are inflating their own numbers in this case.

Given the industries, I can see Squarespace / Priceline & Airbnb having lower DA - there tends to be quite a bit of spam in those industries - traveling sites and CMS/blogging platforms.

Moz & Salesforce are neck and neck however and I would expect this because again, they are both highly regarded and a lot of people use & trust them.

Not saying that's not true for the other sites but again, I want to say this is more industry related.

Hope this helps - good luck!
