To increase the DA value, or quality, of your domain name, you should do the following;

1 - Prepare quality content that will benefit the user.

2 - Write these contents in detail as H1 headings, H2 subheadings and H3 headings

3 - Create link outs, or link building, from the keywords in your content to your other content and external sources.

4 - Support your content with high-quality and authoritative backlinks.

5 - Regularly check for harmful backlinks and reject the ones you detect with Google disavow.

6 - Always do all these processes regularly and sustainably.

After a while, you will see that DA and PA values ​​​​increase.

@ezkrt Thanks. We totally agree, man. I recommend that especially beginners take these explanations into consideration.

Backlinks are very important. It's just like someone recommending you in real life. The more people who recommend you for quality, the higher your workforce will be. You are more known. The same goes for the website.

It's a good idea to use Moz and get support on this. Because you can make a detailed analysis with Moz's link analysis tools. Thus, you will get the right backlink strategy from where you should get backlinks and which ones you should reject.

The truth is that; Yes, the DA value is important. But to increase it in a valuable way, you must focus on quality. Instead of thinking about why the DA score is low, you should add quality and reader-friendly content to your site. Also, your site should not have technical SEO issues. If you care about quality, you can observe that your DA score increases proportionally. Take it easy everyone.
