Backlinks
But content creation is only 40% of the work done. If you need to make a mark, you need to actively promote that. And when you start talking about promotion, backlink building is the first step. And there are very good metrics, such as DA and PA, that help find out how good your backlinks are till now. They help you predict where your website will stand in search results by calculating the number of backlinks you have and their quality.
So, while many people are tempted to increase the number of backlinks, do not fall prey to cheap techniques. Many people are tempted to create backlinks from any random website, good or bad, just to increase the number.
