Increasing the blog's DA is very trending these days and almost all bloggers are looking to achieve this milestone to sell guest posts and niche edits. But to me the real DA is purely relevant to the site's ability to quickly index and rank an article.
Back to the question; you can increase the blog's DA by publishing quality content, making social media presence, solve people problems in real terms and must have a long term history on Google.
I know the website named "https://ausopenschedule.com/ and i believed that this site has achieved the 50+ DA in real terms!
Cheers
