What is meta description?
<meta name="description"> is an HTML meta tag that contains a short description of a page's content. It is not displayed on the page itself, but is used by search engines and social networks.
What meta description does:
-
Appears in search results - as text below the title. This is what the user sees before clicking. Example:
javascript<meta name="description" content="Buy laptops in Kyiv - wide selection, model comparison and delivery."> -
Affects CTR (click-through rate) - the clearer and more attractive the description, the higher the chance the user will click.
-
Does not directly affect ranking (according to Google), but it affects it indirectly through user behavior (a higher CTR means better behavioral signals, which means higher positions).
Recommendations:
- Write a unique description for each page
- Length: up to 150-160 characters, otherwise it gets truncated
- Include the main target keyword
- Make the description clear, concise, and attractive
Conclusion:
meta description is like a preview of the page. It does not rank a page directly, but it draws the user in, sets expectations, and can decide whether they click or scroll past.
