I am trying to learn how to create back-links and how they work and I am creating back-links for my website Pakistan Humara | Pakistan Humara
Now when I create a link to some website let say any forum or any blog, the forum or blog has domain authority but when I start a new post and enter my link there that page don't have Page Authority. For example have a look at this back-link Pakistan Super League
Are these links good ? and how to increase page authority of these links ? and Does DA and PA really matter ?
