    What is this check?

    This check reports the total number of backlinks (external links from other websites) pointing to your domain, along with the number of unique referring domains. A high count of quality backlinks from diverse domains is one of the strongest ranking signals.

    Why is it important?

    Backlinks remain one of Google's most important ranking factors. They serve as 'votes of confidence' from other websites. The number and quality of unique referring domains is often more important than the raw number of individual links.

    What is the impact?

    Pages and domains with more high-quality backlinks from diverse referring domains consistently rank higher in search results. This is one of the most well-established correlations in SEO.
