Why my DA dropped Suddenly?

I want to know why my site's DA got changed suddenly? Whereas the DA of other sites of my competitors remained the same.

It happened just a few days ago and i noticed it today!

I need info on embedding youtube videos inside blog posts as well. As per a study i found after inclusion of youtube embeds inside posts, the DA drops allot. But when we remove the embeds then DA comes back to normal.

Can somebody explains what is it with this behavior of DA?

Hi there,

Sam from Moz's Help Team here!

The change you've noticed would be due to the fact that we updated the way in which we calculate DA as of March 5th. The new DA has been launched with the purpose of improving our ability to predict a site’s ranking ability with even better accuracy. This update aims to give us a more accurate depiction of your site’s influence over time.

This doesn't mean we’ve started from scratch with our calculations; in fact, all of the features that went into the old DA model are also present in the new DA model as we’ve added more complexity around them. This includes a better understanding and consideration for the quality of the site linking to the site you’re researching, and links to a page that redirect to another page.

Please note, when tracking your DA and the Link Building work you’re performing, DA should always be looked at in comparison to your target competitors, never as a standalone metric.

I hope this helps but please let us know if there's more we can help to clarify!
