What is Domain Authority (DA)?
Domain Authority is a 0-100 score (created by Moz) that predicts a site's ability to rank in Google.
How is it calculated?
- ●Number and quality of backlinks
- ●Diversity of referring domains
- ●Domain age and history
- ●Moz's proprietary algorithm
Scale
- ●0-20: New sites or those with few links
- ●20-40: Established sites with a decent link profile
- ●40-60: Popular sites with good authority
- ●60-80: Highly authoritative sites
- ●80-100: Web giants (Google, Wikipedia, Facebook)
Warning
- ●It's not an official Google metric
- ●DA is relative (compare it to your competitors)
- ●A high DA doesn't guarantee good ranking
SEO Impact
DA is a useful indicator for evaluating your site's strength versus the competition and identifying backlink opportunities.
