Metadata is the key data used to describe other pieces of content. It is used for communicating and clarifying website information for search engines, playing a pivotal role in a successful SEO strategy. Metadata is invisible to website visitors. It works behind the curtains in the HTML of web pages to communicate important information about your website.
Metadata is a series of micro-communications that delivers search engines like Google with important information about each page's content, purpose, and characteristics. It is a structured way of communicating information about a data set that tells search engines whether a particular web page is relevant enough to be displayed in search results for a specific search query.
The Metadata of your website consists of page titles, description tag, canonical tag, alt text tag, keywords, links, image tag, and header tag. Metadata is greatly responsible for improving your website’s visibility in organic search results.
