Frequently asked questions
Is Domain Authority a Google ranking factor?
No. Google has confirmed it uses no such single score — DA/DR are third-party comparison metrics.
How do I increase authority?
Earn links from more unique, relevant referring domains — quantity of referring domains is the dominant factor in every authority formula.
