Autorité du domaine (DA)

Domain Authority (DA) is a metric in digital marketing and search engine optimization (SEO) that quantifies the overall strength and credibility of an entire domain or website. Developed by Moz, a leading SEO software provider, Domain Authority is a numerical score ranging from 0 to 100. The higher the score, the greater the potential for a website to rank well on search engine results pages (SERPs).

The DA metric is calculated by considering various factors, including the quality and quantity of inbound links, the diversity of linking domains, and other relevant signals. Websites with a strong and authoritative link profile tend to have higher Domain Authority scores, indicating to search engines that they are trustworthy and provide valuable content.

Digital marketers use Domain Authority as a comparative tool to assess the relative strength of different websites or to track the effectiveness of their SEO strategies. It is important to note that DA is a relative metric, and changes in the algorithm or link landscape can impact scores over time.
