SEO is a vast area of different techniques which requires a standalone set of tutorials. However there are few things you should know about right away.
When your website is displayed on Google, it utilizes
title element for a link text and
meta description for a text description below.
You already know how to put a title into your web page, but
meta description is something new. You can put this description into your web page like that:
<head> <title>My Awesome Web Page</title> <meta name="description" content="A description that will appear in the search results." /> </head>
Also you should use only one
h1 element because it's a most major headline of your web page which should reflect the essense of a page content.
There are some other data which Google could utilize from your site and use it inside a search result snippet, however it's a very different area which we will discuss some later.
