If other websites trust yours, then Google will trust it too
Google is the most trusted platform globally; therefore, Google has to trust what you are saying is what you are. One of the key elements that Google’s algorithm looks at is who is trusting you. These are call backlinks; other websites that link to yours are on-topic and have a higher DR (Google domain ranking) than your website. However, a successful backlink campaign takes time, but the results over time will speak for themselves.
