The service provides analysis of a website's content to indicate tags that accurately detect and list words that characterize the site's overall body of information. Analysis covers the semantics of text found on the site as well as its structure, discoverable metadata associated with it, link text, and related factors. The result provides free-text strings and words typical of the website's content.
API methods support submission of a website URL for analysis. Methods apply an auto-learning algorithm that detects possible topic tags with an accuracy score for each potential tag. It returns the tags that most accurately characterize the site overall.
