Hi,
Hope this enlightens the main issues regarding on how to improve DA and PA.
First, about the inbound links; although you have 18 domains pointing links to your website, 12 of the 18 domains had set the links as nofollow: https://analytics.moz.com/pro/link-explorer/linking-domains?site=https%3A%2F%2Fpickhunting.com%2F&src=mb&state=not_deleted&target=domain&type=nofollow
The website has 22 page titles equal to each H1. It is a best practise to include the Brand at the end of the page title. Why at the right end? Brand matters a lot, but first the name and keywords that tells the potential visitors and to the algorithms of the Search Engines what each page is about. At the same time, by including the brand into each page title, you will differentiate the page title from the H1 as it should be.
If somebody is looking for your brand, that action does not need SEO, due to already knows about you. SEO is for new searchers looking for your products and/or services.
Page title: About | Pick Hunting
H1: About
Maybe, you can set up unique meta descriptions for each page. Perhaps using the free Yoast plugin can help with the task. Good luck and Happy New Year 2020!
