Backlinks with high DA but PA1

[MozVpn]

Whenever we get new backlinks, its always on a PA 1 page, does this pass a lot of link juice as long as the DA is high?

I know the PA can  go up by promoting the page, but i rather promote my own website than one page linking to my site. Any thoughts on this?

Hello there,
Remember that PA1 means that the page was not crawled by moz or it doesnt have anything of linkbuilding seen by moz.

The question about passing linkjuice, is tricky. Every link passes linkjuice (some more, some less). You should focus in whether the link is ok to be there. The first check you must do is analyze for some spam flags in that page, or if it is a relevant&related topic with your site.

That "PA ca go up by promoting the page" is not right. Moz's gives a number in their metrics in a 90% based on the backlink profile of that page/domain. (speking about PA, DA).
Here some resources:

• What is Page Authority(PA)? - Begginers guide to linkbuilding - Moz
  - Targeted Link Building in 2016 - Whiteboard Friday

Best luck!
