is DA and PA also Dead after Page Rank???

Moz metrics can fluctuate sometimes but PA and DA are very much in the game.

Yes
Since May 2011, Google many times changed their algorithm, but Moz.com remained in a Stone Age.
As the result, in 2016 the Moz metrics are completely meaningless for seo purpose. Thousands domains with high DA are google penalized or banned.
Strange that domains with hundred pages have no one keyword ranked in google, but they have high Moz domain authority.

Whats going on friends really its affects on our sales too.

if DA PA and page ranks algorithm dead how we will do business in Monster Backlinks because we all here working on Google page ranking, directory submisson,blog posting etc is this work also dead any one have any knowledge please share.

i thinks its already dead.

Yes that is true. That's why you will notice clients are now preferring quality services over PR submission, bookmarks, profile links.

No it is not dead

To be honest, I am wondering why there is that notion that domain authority and page authority is not functioning anymore, I mean not a factor with search engines anymore. My take on this issue is that as long as the search engines are alive an kicking, all those related to the search engines operations will also be alive and kicking. SEO will always be there that includes domain authority and page authority for the ranking by the search engines – it’s not only for Google but also for the other search engines.
