what is meta tag in seo

June 28, 2026

Meta tag in SEO means a small piece of HTML code placed in a page’s <head> section that gives search engines and browsers information about the page. Meta tags help search engines understand what a page is about and can influence how it appears in search results, especially the title and description shown to users.

Quick Scoop

A meta tag is not usually visible on the page itself, but it sits in the source code and carries metadata like description, robots instructions, viewport settings, and social sharing details.

In SEO, the most important ones are typically the meta title and meta description , because they affect relevance and click-through rate in search results.

Why It Matters

Meta tags help search engines crawl, interpret, and index your page more effectively.

They can also control whether a page should be indexed, how it behaves on mobile, and how it appears when shared on social platforms.

Common Meta Tags

Tag| Purpose
---|---
Description| Gives a short summary of the page and may appear in search snippets 23.
Robots| Tells search engines whether to index or follow links on the page 23.
Viewport| Helps the page display properly on mobile devices 2.
Open Graph| Controls how the page looks when shared on social media 29.
Title tag| Shows the page title in search results; technically not a meta tag, but very important for SEO 25.

Simple Example

html

<head>
  <title>Best Running Shoes for Beginners</title>
  <meta name="description" content="Find the best running shoes for beginners with comfort, support, and value." />
  <meta name="robots" content="index, follow" />
</head>

Best Practice

Keep the title clear and descriptive, and make the meta description concise, natural, and relevant to the page content.

Avoid stuffing keywords; a good meta tag should help both search engines and people understand the page quickly.
