When I use opensiteexplorer, they use "domain authority" in 1 - 100 scale.. How to increase this number to my domains n website?

Link building is the way to increase your domain authority.

Generally links to any part of your website will slowly push your DA up. So continue getting quality links and wait for the next few updates to see your DA go up.

I wouldn't fuss it if your site doesn't have a high DA or links aren't being found. Google will most likely have them indexed anyway.
