What are HTML <meta> Tags
Meta-data is represented by the <meta> tag. Meta-data means data about data. In the simplest terms, this tag provides information about the HTML document.
The contents of the <meta> tag are not displayed on the webpage. Meta-data is used by browsers and search engines. Search engines and browsers get information about the web page through <meta> tags.
For example, search engines get information about the author of the web page by <meta> tag and web browser get information such as viewport by <meta> tag, which helps to present the webpage correctly.
The information given below can be provided by <meta> tags.
Description
You can provide a description of the web page by using <meta> tag. This description is shown in the search results by search engines. When your web page is shown in the search results, the same description is shown below the page title. If you do not define the description by the <meta> tag then search engines use some of the starting lines of the article as a description.
Keywords
You can provide information about keywords related to your webpage to search engines by using <meta> tag. Keywords are important for ranking in search results. From keywords, search engines know with which topic related information is provided on a particular page.

Last Modified
