Frequently asked questions
What is website authority?
Website authority is an estimate of how trusted and established a domain is. Older, more popular and well linked websites usually find it easier to rank in search engines.
How is the authority score calculated?
The score adds up to 100 points: up to 55 for global popularity (Tranco top sites ranking), 20 for domain age, 10 for web archive history and 15 for trust checks such as HTTPS and a fast, indexable homepage.
Is this the same as Moz DA or Ahrefs DR?
No. Moz DA and Ahrefs DR are proprietary metrics based on those companies' own link indexes. Our score uses free public data, so use it to compare websites with each other rather than with DA or DR values.
How can I increase my website authority?
Earn links from respected websites in your industry, publish genuinely useful content that people share, keep your site fast and secure, and stay consistent over time.
