What is the difference between Domain Trust and Page Trust?
Domain Trust is the overall score of a domain’s authority, meaning how well the entire domain is likely to rank. Other tools have similar metrics, often called Domain Rating or Domain Authority. Page Trust applies the same scoring logic to individual pages, estimating each page’s potential to rank in search results. Both metrics are calculated using a PageRank-style algorithm, combining the number and quality of backlinks and referring domains.
How is Domain Trust (DT) different from Domain Authority (DA)?
Domain Trust (DT) is SE Ranking’s proprietary score. It shows how trustworthy a website is based on the quality of its backlinks. Domain Authority (DA), created by Moz, is another popular metric that predicts how likely a site is to rank in search results. Both measure site strength, but they use different methods and data, so the numbers may not match.
