In SEO, anchor text refers to the clickable words or phrases that appear as hyperlinks on a webpage. When a user clicks on an anchor text, it takes them to another webpage, either on the same site or a different one.
There are different types of anchor text that can be used in SEO, including exact match, partial match, branded, and generic. Exact match anchor text uses the exact keyword or phrase that the linked page is trying to rank for, while partial match anchor text includes a variation of the keyword or phrase.
