Domain Signal

Domain signals are the collection of domain-level attributes that search engines use when evaluating a site's overall ranking potential. These include [[domain-authority|domain authority]], [[domain-age|domain age]], [[backlinks|backlink]] profile quality, historical spam signals, and the choice of [[tld|TLD]]. Unlike page-level signals (title tags, content quality), domain signals apply uniformly across the entire site, meaning a strong or weak signal at the domain level elevates or suppresses every page simultaneously.
