Welcome to the Q&A Forum

Hi there, Thanks for the question. The first thing to say is that DA/PA are Moz metrics and aren't connected directly to Google and how they rank your website. So the actual answer to your question is that having your DA/PA increase will not directly effect rankings because Google doesn't use DA or PA. Having said that, Moz have designed DA and PA to try to predict how well a domain or page could rank in search results, so generally speaking, the higher the numbers, the more chance you have of competing. Overall, the focus when it comes to authority should be for you to generate relevant, quality links from other domains to yours which will mean that Google pass authority to your website and give it a better chance of ranking. Alongside this, DA and PA may also go up which gives you a rough measurement of your own authority. Hope that helps! Paddy
