Has anyone seen a recent drop in Page Authority?

[vikassocialbeat]

We have seen a sizeable drop in Page Authority for three of our key category pages over the last one week.The total number of linking root domains has increased for all the three pages. We have  disavowed a few spammy links but we doubt that would cause a drop in page authority. The domain authority is unchanged.Is there any way we could figure out the cause of the drop? Has anyone else also noticed a drop in page authority for their pages? Hello,We have seen a sizeable drop in Page Authority for three of our key category pages over the last one week.The total number of linking root domains has increased for all the three pages.

Have you read the following post from Rand/Moz about the recent index changes. This is likely the main reason behind the change in your PA and any fluctuations you have seen.

I would suggest looking at your competitors who have similar content and pages to see if they too have also seen this same drop as in many cases the change is relative to others in your niche/area etc.

There have been many people this week reporting huge drops and fluctuations in their websites' DA and PA. This has been put down to the recent updates with Mozscape and how it is calculated. Rand explains it quite well in this post: https://moz.com/community/q/da-pa-fluctuations-how-to-interpret-apply-understand-these-ml-based-scores

Any drops in DA and PA don't necessarily mean that your website and/or link profile has decreased in quality. Which is why it's always recommended to compare your DA/PA metrics against your competitors rather than against your own website's historical metrics to get a more accurate view of how DA and PA updates are affecting you.
