Domain Authority (DA) is a search engine ranking score developed by Moz, which predicts how well a website will rank in search engine results pages (SERPs). The score ranges from 1 to 100, with higher scores indicating a greater likelihood of ranking well in search results. The score is based on a combination of factors, such as the number and quality of external links pointing to the website, the website’s age, and its overall content quality. Domain Authority is useful for comparing the strength of different websites and for identifying opportunities for link building and SEO improvement. However, it is important to note that DA is not a direct measure of a website’s search engine ranking and should be used as a general guideline.
