Domain Authority (DA) is a metric developed by Moz that predicts how well a website will rank on search engine results pages (SERPs). It is measured on a scale from 0 to 100, with higher scores indicating a greater likelihood of ranking well.
Domain Authority is calculated based on a variety of factors, including the number and quality of inbound links pointing to the domain, the age of the domain, and the overall quality of the website’s content and user experience. Moz uses a machine learning algorithm to analyze these factors and assign a score to each domain.
It’s important to note that Domain Authority is just one of many factors that search engines use to determine how to rank websites. Other important factors include the relevance of the website’s content to the user’s search query, the user experience of the website, and the quality of the website’s backlinks.
It’s also worth noting that Domain Authority is a relative metric, meaning that it’s only useful for comparing the relative strength of different domains. It’s not useful for comparing the absolute strength of a domain or predicting its exact ranking on SERPs.
