How do you build domain trust and authority ?

[jlane9]

I am doing some link building and was hoping to get some clear information about the quality of the links and what I need to build a higher domain trust and authority.

My sites page I wish to build for has: DA 22   PA 33  MR 4.6

I am looking at back links with these figures

Considering outbound links are equal, which pages can help build my page ?

page1   DA 66 PA 48 MR 4.8

page2   DA 66 PA 35 MR 3.75

page 3  DA 66 PA  28 MR 3.5

page 4  DA  41 PA 18 MR 2.73

Page 4  DA 41 PA 18 MR 1.87

Do I need back links with a Domain Authority Higher than my own ?

PA higher than my own ?

or MR higher than my own ?

or would any of these pages be able to improve my own ?

Thank you in advance for helping with this as I do not want to spend 6 months building the wrong links.

Are the sites relevant to your site? Will they be useful to the users of the other site? Are these links paid?

Well,

I would like a general answer about the DA, PA and MR for sure.

However these particular pages are from directories listed here on SEOMOZ's list of directories worth exploring.

All would be links in a category for my site.

There are both free listings

and a fee to review the listing option. ( considered a paid link ?)

DA and PA are calculated by links and quality of the links.

And the trust ranking is based on the above along with the age of the domain.

Honestly, if you are doing these just for higher DA and PA, it won't do you too good. Quality links are really what gets business. If I get 1,000 links from toilet blogs and I sell TVs, their links won't mean a thing to me because no one will click those links.

Hi Joseph,

From a purely numbers point of view, all of this links could help your site's metrics, but I think we're missing the larger picture.

Before we talk about that though, here's a couple of pointers:

• don't forget about MozTrust in your metrics, especially dealing with directory sites. Sites with high MozRank and low MozTrust should be avoided
• Also when dealing with directories, this is one of the few times that looking at PageRank is actually useful. A big difference between MR/DA and toolbar PageRank is a big warning sign that the directory might have been penalized

What's more important is probably the relevancy of the page. This is even more important than the metrics. A link from a relevant high trusted domain, even if it has almost zero MozRank, is better than an off topic link in the footer of page with great MozRank (some exceptions apply)

Hope this helps! Best of luck with your SEO!
