Hi.
There is only one way to this. Newsflash - The right way.
Additionally, if you are only focusing on this (DA score) thing, then your destiny now has an impeding doom !!!
Instead of trying to raise your DA score, your main focus should be on these items.
1. Onpage technical SEO.
2. Quality content creation.
3. Outreach methods including email pitching and guest posting.
4. Public Relations (PR)
5. Social Media References.
6. Keyword research.
7. Competitor analysis
Doing these things will see your websites overall authority increase over time for a number of different reasons. In the grand scheme of things, the MOZ DA score means almost nothing these days. Search engines such as good pay no attention to it and are not linked in terms of algo considerations.
If you are looking for some quick fix to increase the DA score, I am sorry, it does not exist. That's of course if you head over to places like Fiverr where they sell " Increase Your DA score" gigs. So what's up with that you may ask?
Okay, so here's the kicker. Those digital marketing bottom feeders use a pointless and worthless method called " creating redirect notices" Note, this is different from 301 domain redirects. Anyways, they create a bunch of these redirect notices that will make the MOZ DA tool think they are real links from real websites, hence it will show your DA score increasing. But the fact is. Google does not count these pointless redirect notices, and a fake score will show in the MOZ DA tool.
Why the DA score is useless and pointless metric?
If you are not aware, you will be after reading this. Did you know that a DA10 site can be 5 times more powerful than a DA40 site. Yep. it can be! There are over 200 different ranking factors. And the MOZ DA score is not one of them.
Don't focus on the DA score buddy, just focus on giving your victors the best experience possible and if you are going to manually build links, do it the right way.
Cheers mate.
