Introduction: What Is the Meta Robots Tag in SEO?

The Meta Robots tag is an HTML element that tells search engines how to crawl and index a webpage. It sits in the <head> section of your HTML and can control:

Indexing (whether a page should appear in Google).
Following (whether links on the page should pass authority).
Snippets (whether Google should show content snippets in SERPs).

👉 Example:

<meta name="robots" content="noindex, nofollow">

👉 Use SEO Audit Tool to check if your site uses Meta Robots tags correctly.
