Microformats are special tags used to mark up content on a web page. They help Google understand the meaning of the information presented. Primarily used for search engine optimization (SEO), they improve a page’s visibility in search engine results and can offer various advantages. By adding predefined terms to existing XHTML tag classes, microformats semantically enrich the data displayed on the web page. This additional layer of information can be used by both users and machines, thus adding value to the presentation of online content.
