Domain authority (DA) is a score (typically from 1–100) developed by SEO tools to predict how well a website will rank in search results. It’s based on factors like backlink quality, content depth, and overall site trustworthiness.
In B2B marketing, DA is often used as a benchmark for digital competitiveness. It provides a quick view of how a company’s website compares to others within its industry. Monitoring domain authority trends helps content and SEO teams evaluate the impact of their publishing strategy, link-building quality, and technical performance. When combined with keyword rankings and referral traffic, it paints a clearer picture of how organic authority is evolving.
