Domain Strength Indicators
What is Domain Authority?
Domain Authority (DA) is a metric developed by Moz that rates the strength and trustworthiness of a domain on a scale of 1 to 100. It serves as an important indicator of a website's potential to rank in search engine results.

Domain Authority is based on several factors that reflect the overall strength of a domain:
- Reference Profile: Number and quality of inbound links
- Root Domain Authority: Strength of the main domain
