如何判断外链质量？DA值是关键指标
How to evaluate backlink quality? DA value is the key metric
MOZ发明的DA（Domain Authority，域名权威）值是判断外链质量的重要标准。DA值可以理解为：
MOZ's DA (Domain Authority) is an important standard for judging backlink quality. DA value can be understood as:
• 将谷歌比作一个村庄，DA值代表其他村民的声誉值
• Imagine Google as a village, DA represents the reputation value of other villagers
• 获得高DA值网站的链接，相当于得到"村里德高望重者"的背书
• Getting links from high-DA websites is like receiving endorsements from "respected villagers"
