Before talking about search engine optimization of your website, you should understand what you can see on the Google Search results page, namely in its search results section.
Each search result contains a title, URL, and snippet.
The first blue line of any search result is the Title of the webpage. To go to the site, you should click on the title.
Below the Title, there is a URL in the green color. The URL (Uniform Resource Locator) specifies the location of the particular webpage on the Web. In other words, the URL is the web address of the page. Words in the URL are bolded if they are present in the user's search query.
Under the URL is a Snippet – a short description of the webpage. Words that are present in the user’s search query are bolded to help users make decision whether current page is about what they are looking for.
Some search results have Sitelinks that are links to the website pages which appear under the main search result. Sitelinks help users navigate the current website and find content on the site which they are interested in faster.
