Domain Authority vs. Page Authority?

[jonnyholt]

I have a couple of questions about this.  First of all is one more important than the other?  Also, I currently have a website setup for www.domain.com, should I try to change that to domain.com without the www?

How is it possible to grow page authority yet I am having a hard time growing domain authority.

Hi Jonathan,

Domain vs Page authority: http://moz.com/learn/seo/domain-authority (includes a bit on how to influence/grow domain authority, and page authority would be focusing your SEO efforts on one page as opposed to the whole website)

Also Karl has a great response here: http://moz.com/community/q/what-s-more-important-page-authority-vs-domain-authority

As for www or not. Choose and stick with one, its important in terms of SEO link building to have consistency when you are building links to your pages. So either http://domain.com or http://www.domain.com is fine but choose one.

Also do a 301 permanent redirect to the preferred choice. Without this you might run in to these issues.

Hope this helps

Ok, so you have a website domain .com and you are wondering if you should move it towards the www version or not! Actually it’s completely your choice but sticking up to one version is important. I personally go with www version but this is because I like that version and there is no technical shit behind it!

PA defines the links that you are getting on that particular page and this varies from one URL to another of the same domain. Whereas DA remains same for the entire website! According to Moz DA or Domain Authority represents Moz's best prediction for how a website will perform in search engine rankings. DA gets calculated by combining all of other link metrics—linking root domains, number of total links, MozRank, MozTrust, etc.—into a single score.

Increase numbers of links for the domain will defiantly going to increase DA of the website for increase PA you have to increase the links on that particular page.

Hope this helps!

One cost effective benefit of using the root domain (no W's) is in setting up a MOZ campaign. If you set it up as a sub domain - www.sales.com - MOZ will track that version only. If you happen to have sub domains connected to that site - the performance of those keywords will not be tracked.

Setting up your campaign with the root domain, sales.com -- auto.sales.com, homes.sales.com, insurance.sales.com, ad nauseam, will be all tracked within a single campaign slot.
