Anchor text is the clickable text in a hyperlink. SEO best practices dictate that anchor text is relevant to the page you're linking to, rather than generic text. The blue underlined anchor text is the most common as it is the web standard, although it is possible to change the color and underlining through HTML code.
Texts that link to another location or document on the Web are referred to as anchor texts. In short, it’s clickable text in a hyperlink. For instance, in the sentence “Wikipedia gives an overview of anchor texts," Wikipedia is the anchor text. You can create it using this simple HTML code.
