Anyone have Tips for increasing Domain Authority?

My 2 yr old site has leveled out at about 20, which seems low as I see some really crappy sites with 50+

I’m a little discouraged. My website has been around for 2 years now, but traffic seems stuck around 20 visitors a day.

Honestly, I see some websites that aren’t that great getting 50+ visitors, and it makes me wonder what I’m doing wrong.

Improve internal linking. Make it easy for users to navigate within your site by having a clear information architecture and linking to relevant internal pages. This helps search engines understand what your site is about.
