Domain Authority dropped by 9!

[Bendall]

Hello Mozzers,

I have logged onto MOZ this morning to see that my domain authority has slipped (seemingly overnight) from 61 to 52!

The competitors i track have also slipped but not as dramatically as me and my domain.

Is this an expected change in the algorithm? Have all industries been affected?

Any help / explanation would be very much appreciated.

Ben

Thank you for your response Sean, our domain is nuffieldhealth.com.

I will email help@moz.com with full details.

We have a number of broken links, duplicate page titles etc which we are aware of and are working through, however these are not new problems to our site - and also our tracked competitors DA slipped to a similar extent.

Many thanks for the reply

Ben

Hi There,

So this is a pretty tricky one to answer because there quite a few factors that go into our Domain Authority Metric in OSE. In this case I would recommend checking out your inbound links to make sure that you no major changes have occurred to the linking structure of your site with our latest index. If you could let me know the URL you are checking out I would be happy to take a look.

You may want to write to us directly at help@moz.com so we can really dig into the issue. We generally prefer to use help@moz.com because if it looks like an issue on our end we can pass it directly up to our engineers. Once we hear word back from them we can provide you with more specific feedback.

Hope this helps and if you have any other questions or concerns please feel free to ask.

Have a great day!

DA will shift up or down depending on the size of OSE's lastest index. A bigger index = DA goes up, a smaller index = DA goes down.

Hi Ben

Ours dropped last week by 6, and our competitors we're similar between 4 and 6 drops so I wasn't too worried.

I never like drops especially when we drop more than our competitors, but DA is just a score and I now tend to look at traffic and revenue from Organic, more than things like DA and even rankings, these are good indicators but these days its just about the bottom line, Google is getting hard to predict and even rankings change per person, so I am not worried by these factors any more.

But your not the only person to see significant drops.

Thanks

Andy
