Why is Page Authority dropping?

[BeckyKey]

Hi

I'm trying to review pages which have previously ranked, but in March have dropped out completely.

Some of these pages I can see have dropped to having a Page Authority of 1, we haven't changed anything on these pages, so is there a reason why the authority has dropped? These pages only had around 8 - 10 Page Authority to begin with.

I'm trying to identify why we have lost keywords, and if it has anything to do with the Google Updates in March

Here are examples of the pages with drops:

http://www.key.co.uk/en/key/metal-feet-for-heavy-duty-steel-shelving

Thank you!

Hey,

Yes sorry you've lost me!

I've seen a lot of backlinks from one of our sister companies in March, they are no follow, but they're footer links - would this have any impact?

Thanks!

Hello Becky,

As other said before, it could be a problem related to the "authority" passed by the backlinks.
But! I do strongly believe that there is no problem in your site nor in your backlink profile. Remember that PA and DA are logaritmic metrics with a maximum of 100. So if the most authoritative pages get better backlinks and increase their linkjuice there is no room to get a higher than 100 score. That said, all scores below that will decrease.

That must not be confused, you might have a better authority but the best pages too, therefore your PA/DA decreased even with a better metrics.

This might be a little confusing, so if you don´t understand afer my explanation, please let me know.

Best wishes.
GR.

Hi,

Check your backlinks. Probably one of them are not link to your blog anymore. You can check your backlinks with Moz Open Site Explorer.

Hi,

Have you checked the health of your backlinks, specifically to those pages? A client of mine disavowed a large number of domains and lost some PA, however this should return once the low value of the disavowed backlinks is recognised.

On a related note, have you seen a large increase in backlinks and analysed the "spam score" of those domains?
