Drop in Domain Authority and MozTrust -> -20% in traffic?

[uMoR]

Hello Everybody,
with the latest seomoz index update for OSE my website had a big drop in Domain Authority and MozTrust and at the same time a drop in SEO traffic.

It seems to be a correlation between the drop in the Seomoz metric and SEO traffic, infact from the 9th of August we lost the 20% of traffic (the 2nd of august our DA and MT was normal, the 15th Seomoz show the drop).

Unfortunately it seems that this trend is valid only for my website and not because of a Seomoz index error: my competitor still have the same DA and MT.

I will check for sure if, with the next index update, there will be some change in DA or MT, anyway which are your suggestion? How can I know what has happened to my link profile and the cause of this big change?

Advice are welcome!

if you want to double check your information you can try using some of the tools below. I would put most of my stock in SEOmoz however you may want to do a trial to see if all the data matches. I am not at all saying that there's something wrong with the information you are given however using all of these tools the same ones I use in combination with SEOmoz seems to be the best way of getting a full 360° look at my websites.

I though this might sound funny but look at all the excellent tools in SEM Rush partners

I hope I was of help to you.

The obvious answer (but not necessarily the correct one) is you lost some important links pointing to your website somewhere. This would cause a drop in your metrics, and could cause a corresponding drop in your organic traffic.

I might run a check with Majectic to look at your historic backlink profile, and also Google Webmaster tools Impressions report, to see if it matches the drop in traffic you've found.

Are you aware of any links that you've lost? You can comb through your referrer data in Google Analytics to see if any good sources suddenly dried up in the weeks/months leading up to the drop.

On the other hand, it could all be coincidence. The drop in DA could be a random event caused by the Mozscape crawlers simply missing an important set of links, which happens occasionally. And the drop in rankings could be due to an algorythm change (Check the Google Algo Update History to see if any of the dates match up)

If you find any missing links, you can work to regain them. Otherwise the only way back is probably to build new, better links.

Hope this helps! Best of luck with your SEO!
