Anchor text is a term used in search engine optimization (SEO) and refers to the clickable text that appears as a hyperlink on a web page. It's commonly found in links pointing to other websites, such as those within articles or blog posts. The anchor text helps users understand what they will find when clicking on it, providing context for the destination of the link. In SEO, optimizing anchor texts can improve search engine rankings by using relevant keywords and phrases that help describe the linked content accurately.
