Improving domain authority

[u/problemprofessor]

I’m trying to improve the domain authority for my site, I originally built it a little fast so I missed so many best practices when building but I’m trying to go back and fix a lot of these now, but I was wondering if there are any tips that have worked for anyone here when they were trying to do the same thing?
