Meta tag -
A special HTML tag that provides information about a Web page. Unlike normal HTML tags, meta tags do not affect how the page is displayed. Instead, they provide information such as who created the page, how often it is updated, what the page is about, and which keywords represent the page's content. Many search enginesuse this information when building their indices.
H1 tag -
The h1 tag is the most important tag. Every page must have an h1 tag.
