Anchor text refers to the visible, clickable words or phrases in a hyperlink. Typically highlighted in a different color and often underlined, anchor text provides users with context about the content they will access if they click the link. In addition to guiding user navigation, anchor text plays a significant role in search engine optimization (SEO), as search engines use it to determine the relevance and subject matter of the linked page. Effective anchor text is concise, descriptive, and directly related to the destination content.
