Meta tags are snippets of text that provide search engines with information about the content of a webpage. They are used to help search engine algorithms accurately identify and classify pages so they can be presented in relevant results to users. Meta tags can include descriptions, titles, and keywords that provide information on the page’s content and its purpose. Descriptions are typically between 120-160 characters and give an overview of what the page is about; titles should have fewer than 65 characters; and keywords provide a list of terms related to the page’s content which helps with indexing. In addition to these standard meta tags, social media networks may also use their own set of meta tags to determine how content should be indexed or shared within their platforms.
