Description term explained
Description – the name of the meta tag containing a short description of the HTML document. Meta tag used by search engines for processing the search results.
Meta tag when composing your HTML code page is placed in the <head> tag, that is, in the beginning of the document.
Syntax:
<meta name="description" content="Search Engine Optimize"/>
Rules:
- Length of the meta tag is 150 characters. Of course, you can make description and longer, but the search engine will still cut;
 - The text description should be exact occurrence of key phrases;
 - The text should more fully reflect the semantic content of the page;
 - It is necessary to write appealing user-text;
 
Under these rules the text descripcin will be positively perceived by the user, which will lead to lower bounce rate
In conclusion, I should add that the meta tag description should be unique for each page.
