Getting some collection of links pointing to onnuri24.co.kr could have no value or negative impact for your site.
It really makes no difference the total inbound links you have, what matters is the amount of search terms those platforms appear in search for.
That is the critical factor.
Not the fake Moz DA or Domain Rating.
Anyone can manipulate those.
BUT the amount of Google-ranked terms the websites that link to you contain.
That’s the bottom line.
Make sure these backlinks redirect to your site and your rankings will skyrocket!
