Domain Authority (DA) and backlinks are related but different concepts. DA is a metric that predicts how well a website will rank on search engines. It is scored on a scale from 1 to 100, with higher scores indicating greater authority. Backlinks are links from other websites to your site. They are one of the factors that influence DA. Quality backlinks from authoritative sites can improve your DA. DA is a broad measure of a site’s overall SEO strength. Backlinks are specific links that contribute to that strength. Both are important for improving your site’s visibility and rankings.
