The <h1> tag stands for the most important and boldest heading of the web page and the <h6> stands for the least important and smallest one.
Use only one <h1> tag on any web page. The tag should describe what is your page about and contain keyword, as it helps to improve rankings in Google.
The hierarchy of headings in HTML look like this:
<html> <head> <title>Title of the document</title> </head> <body> <h1>This is heading 1</h1> <h2>This is heading 2</h2> <h3>This is heading 3</h3> <h4>This is heading 4</h4> <h5>This is heading 5</h5> <h6>This is heading 6</h6> </body> </html>
