My Domain Authority Dropped Dramatically..Can Someone Tell Me Why??

[Caseman]

Over the last month or so my Domain Authority, my MozRank and MozTrust have all dropped off considerably. I haven't been doing anything different. So I don't know where to turn or what to do to get it back to where it was. The effects are horrible on my SEO.

Can anyone out there tell me what it is I can do to why they dropped? Or more importantly, how can I improve it?

Hmm.. Perhaps their main links were still included?  Mine dropped right along with my competitors.

Have you noticed link volume loss in other tools?

That was the biggest problem, my competitors stayed the same. Some of them even increased in the same time frame.

It was most likely due to the smaller size of the mozscape update http://www.seomoz.org/blog/july-mozscape-update

Basically this months update was smaller than ones in the past, so links (and their metrics) that may have been included in the past might not be showing now because the update indexed less overall.

Check out your stats compared to your competitors and you may see that everyone has dropped by a fairly comparable amount.
