域名信号是搜索引擎评估网站整体排名潜力时使用的域名级属性集合。包括[[domain-authority|域名权威]]、[[domain-age|域名年龄]]、[[backlinks|反向链接]]档案质量、历史垃圾信号以及[[tld|TLD]]的选择。与页面级信号(标题标签、内容质量)不同,域名信号均匀地适用于整个网站,意味着域名层面的强弱信号会同时提升或抑制每个页面的表现。
示例
A domain with a clean history, 10-year age, and thousands of editorial backlinks sends strong positive domain signals, giving every new page it publishes a head start in search rankings.
