Link popularity refers to the quantity of backlinks, which are incoming links directed towards a specific website.
Unlike domain popularity, each backlink is counted individually. For instance, if a car blog contains 10 separate posts linking to a car dealer's website, you would count a total of 10 backlinks. In the past, link popularity was a significant metric for search engines. However, many search engines now prioritize domain popularity, which evaluates both the quantity and quality of backlinks. Therefore, acquiring high-quality backlinks is crucial, as they can direct more visitors to your website.
