Receiving some set of links pointing to onnuri24.co.kr could have no value or worse for your business.
It really isn’t important how many backlinks you have, what is key is the number of keywords those platforms are optimized for.
That is the key factor.
Not the overrated Domain Authority or ahrefs DR score.
These can be faked easily.
BUT the amount of high-traffic search terms the sites that send backlinks to you rank for.
That’s what really matters.
Have such links link to your domain and your site will see real growth!
