Domain Authority Decreased on May 5 Update

[iphony]

Why the Domain Authority of my website decreased? Last month my website www.i-phony.com domain authority was 32/100. but today I see the result is only 23/100 . What was the reason behind this big decrease !!

Your answer is highly appreciated and very valuable for me.

Best regards

Hi Everyone

The weekly delays and the smaller Index are completely separate, but importing the index data into Moz campaigns are affected. A smaller index was necessary for us to release it without further delay. This release has 187 billion links instead of what we originally had planned which possibly between 250-300 billion links. We hope our next index will be intact and released on schedule.

Here are the index details: https://moz.com/products/api/updates

Hello,

I looked this up with open site explorer and it appears a lot of your linking domains look pretty spammy. One step would be to disavow those links and focus on getting better one's. (Your top few are really good links.)

Thanks,

I don't know if it is the reason but I noticed the sites that showed up as backlinks to my site after yesterday's update were much different than those from before the update. After the update my site showed fewer backlinks but my domain authority actually went up. It's possible the Mozscape index crawler visited different sites than it did previously and fewer/lower Domain Authority links were discovered for your site. Either that or your site lost some quality links since the last update.

Have you been monitoring your links with other tools? That could help determine if it's a loss of links or just different links being used to calculate your DA. Either way that seems like a big drop in DA.

Hi there

It more than likely happened because of the issues Moz is having.

But to answer your question beyond that (and if your site continues to see a lower DA), there's no one direct way to answer and fix this. You're going to have to do some research.

Learn about the following:
Domain Authority
Page Authority

As stated by the DA page...

"Unlike other SEO metrics, Domain Authority is difficult to influence directly. It is made up of an aggregate of metrics (MozRank, MozTrust, link profile, and more) that each have an impact on this score. This was done intentionally; this metric is meant to approximate how competitive a given site is in Google.com. Since Google takes a lot of factors into account, a metric that tries to calculate it must incorporate a lot of factors, as well.

The best way to influence this metric is to improve your overall SEO. In particular, you should focus on your link profile—which influences MozRank and MozTrust—by getting more links from other well-linked-to pages."

Take a look at the following resources:
On-Page SEO
Content Audit
How to Conduct a Backlink Audit Link Audit Guide for Effective Link Removals & Risk Mitigation

There are a lot of factors that could go into this, so you need to put your SEO research hat on and dig in!

Hope this helps! Good luck!
