What is Domain Authority?

Domain Authority (DA) is a search engine ranking score developed by Moz that predicts how likely a website is to rank in search engine result pages (SERPs). A Domain Authority score ranges from one to 100, with higher scores corresponding to a greater ability to rank. It is calculated by evaluating multiple factors, including linking root domains and the number of total links, into a single DA score. This tool provides not just the DA, but also the number of linking domains and the "Spam Score," which estimates the percentage of sites with similar features that have been penalized by Google.
