At the beginning of every HTML document is a set of tags called <head>Head Content</head>. Head content includes the page title and some important page elements called meta tags. Meta Tags are HTML codes that include information about the page, such as keywords, page description, and author name. This information is useful to search engines and screen readers, providing them with detailed information about the page.
In the following exercise we will add a page title to our homepage (index.html), a page description, and keywords for search engines.


With the Internet knowing no boundaries, it is important that we always declare the language of the HTML document we are authoring. To do this we have to add a language declaration to our document.
