What are the best ways of improving our domain authority?

[Saunders1865]

My site's domain authority has gone down by a few points recently. What the best ways of increasing it? It's currently 29 out of 100. What is a good domain authority number?

[AndreVanKets]

The more linking Root Domains you have, the higher the authority grows.

Obtaining 100 links from the same websites is no were near as valuable as 100 links from 100 different websites. This will improve your Domain Authority.

Agree with Greg. Also, links from well linked sites typically help the most (as I'm sure everyone knows).

Links from other authoritative sites that are relavent and/or entertaining to your audience will help you gain authority. As long as the users that get to your site and like what they see, share what they see (give you an endorsement) and or bookmark it, you gain authority. Think of it from a user perspective, if you entertain them, educate them, or offer them something of interest they will naturally link to your site.

The anchors to your site must look natural as well. be sure that your inbound links are built mostly of your URL or brand name.

It is likely that your domain authority went down because the size of the index used by OSE shrank significantly.  Last month they indexed about 72 billion URLs, compared to 150 billion the month before.  This month they indexed even less, something like 68 billion URLs.

If some of your backlinks weren't indexed this time, you'll lose domain authority.  There's not a lot you can do about the index shrinking, unless you can provide a few million dollars worth of Hardware for SEOmoz to use.

I'll chime in on the '**what is a good domain number authority'. **

I hope this is an obvious point... There's no magic number. I would suggest that it depends on your vertical, and the keywords for which you are trying to rank. Quick tip - use the SEOmoz SERP overlay tool . When you're doing searches for your target keywords, you can get a quick/rough idea of the type of domain authority/number of linking root domains that will be necessary to be in the conversation for page 1 rankings.
