Understanding what is backlink is important because these links act as signals to Google, showing that a page has value. A page with many high-quality backlinks often earns more trust, which can improve Google rankings and strengthen overall search engine optimization results.

A page with solid signals can jump in rankings because search engines see real value behind it.

These strategies help them earn high quality backlinks instead of weak or spammy ones.
