Hi, hope you are doing well! I have one question regarding my website and I'm hoping fine response from this board and I will get help. Here is a link to my website: ( bit.ly/3g5Goqd ) I'm working on it from 2 years but its domain authority is not increasing, I've done a whole lot like high authority backlinking and content writing but not getting a good response. Any SEO expert there? who can check my website and guide me on what-to-do for increasing DA/PA of my website? I'll be grateful for the support. Thanks in advance.
