Domain Authority - 10 point drop. Should i be worried

[Astute-Media]

We have had a steady rise over the past year and as the DA results came out i was extremely disappointed to see a 10 point drop. Competitors have also dropped but not by this figure.

We have been continuing with the work we have been doing all year. Not the best news to have to share with the client.

Would you use DA as a KPI or is it a little unreliable?

Hello!

It's importat for you to understand that PA, DA or any other metric from some platform are just metrics with their own algorithms.
In Moz's metrics case, they try to express how likely is a domain to rank, using a lot of information from the link profile for a domaina/page. Of course, they are great, but don't know the Google's algorithm, so a drop/increase in a certain metric doesn't have to be correlated with a worse/better ranking.

Also, you must know, that from mozscape update to update, there might be different links crawled. It could be the case that some links that were in a older index weren't crawled in the actual.

In my experience ( and it's how I work), using any metric as a KPI will lead to problems and misunderstandings. I don't use them as a KPI.
for example, how hard would it be to explain that your work was correctly done, if there was some DA loss? (assuming that you've done everything just fine)

Hope I've helped.

If you haven't already, be sure to check the Mozscape API updates page, here: https://moz.com/products/api/updates. As one went live the day before this post.

I'd second what Gaston says about advising against this (and similar metrics) as a KPI.
