What does <meta name="description"> do? Why does it matter for SEO?

The <meta name="description"> tag is used to set a short page description that is not shown on the site, but is visible in search engines, as text below the result's title (the snippet).

It helps search bots and users understand what the page is about, even before visiting it.

#1. Example of the tag

Here:

• name="description": tells the browser and search engine that this is a description;
• content="...": the text itself, up to ~160 characters long.

#2. How it is displayed in search

Search engines (Google, Bing, and others) often use this text for the snippet, a short page description under the link.

Example:

Everything below the title is the content of meta description.

#3. Why it matters for SEO

#1. Increases CTR (clickability)

Even if the search position is not the first one, a well-written description can attract more clicks than competitors.

This is the page's "mini-ad" in the results.

Example of a good description:

Contains keywords ("laptop", "delivery"), a call to action, a time limit: everything that increases clickability.

#2. Helps the search engine understand the page's meaning

<meta name="description"> does not directly affect rankings, but it:

• improves the page's relevance to the query;
• helps algorithms build the snippet more accurately;
• reduces the risk that the search engine substitutes "random text" from the site.

#3. Increases user trust

When the description is:

• clear,
• well written,
• reflective of the page's content,

the person clicks more often and stays on the site longer. This is an indirect SEO factor (behavioral metrics).

#4. Best practices for writing

Example of a good one:

#Summary:

In simple terms: <meta name="description"> is the page's advertising showcase in search. It does not "boost" the site directly, but it makes people click on it more often, and that in turn strengthens rankings.
