Sometimes, you don’t want your entire website - or certain pages - to appear in Google or other search results. Whether your site is under development, being redesigned, or contains private data, you can easily control what gets indexed using a simple file called robots.txt or meta tags.
This guide answers the most common questions about how to close your website (or parts of it) from search engine crawlers efficiently and safely.
Search engine crawlers automatically scan every page on the web 
. However, you might want to restrict access for several reasons, such as:
If your site is still in development or redesign, it’s a good idea to hide it from search engines completely. You can block all crawlers, a specific one, or allow only a single bot using the following examples 
Block all bots:
Block only Google Images:
Allow only Google, block others:
For most small business sites, it’s rare to hide specific pages. But for larger or eCommerce websites, you may want to block service-related or non-public areas such as:
Examples:
Block a single page:
Block an entire section:
Allow only one folder:
You can also block indexing of specific files, scripts, or tracking parameters like UTM tags.
Examples:
Block file types (e.g., images):
Block a folder:
Allow only one file in a folder:
Block scripts:
Block UTM tags:
If you prefer not to use robots.txt, you can add a meta tag directly inside your HTML
Example 1 – Block all crawlers:
Example 2 – Full restriction:
Meta tag options explained:
Tip: You can mix rules like noindex, follow to block content but still let search engines follow links.
Even small syntax errors can cause major indexing issues. Watch out for these:
Missing blank lines between rules
Uppercase letters in directives
Conflicting rules (logical errors)
Forgetting Disallow: directive
Always test your
To block everything → use
To block individual sections → specify their paths
To block via HTML → use
To prevent crawler overload → close scripts, sessions, UTM tags
To allow only one bot → combine Allow and Disallow rules
To verify → use tools like Linkbox or Google Index Checker
Blocking your site or pages from search engines is simple - but must be done carefully. A single misplaced line in robots.txt could make your entire site disappear from Google 
.
Always test before deploying, double-check syntax, and update your rules regularly. By mastering these controls, you’ll protect your data, improve crawl efficiency, and keep your website running smoothly

Why You Might Block a Site from Search Engines
Search engine crawlers automatically scan every page on the web . However, you might want to restrict access for several reasons, such as:- Protecting admin or user areas
- Hiding outdated promotions or event pages
- Preventing scripts, banners, and heavy files from being indexed
- Reducing server load and speeding up indexing
How to Block Your Entire Website
If your site is still in development or redesign, it’s a good idea to hide it from search engines completely. You can block all crawlers, a specific one, or allow only a single bot using the following examples Block all bots:
Code:
User-agent: *
Disallow: /Block only Google Images:
Code:
User-agent: Googlebot-Image
Disallow: /Allow only Google, block others:
Code:
User-agent: *
Disallow: /
User-agent: Google
Allow: /
How to Block Individual Pages or Sections
For most small business sites, it’s rare to hide specific pages. But for larger or eCommerce websites, you may want to block service-related or non-public areas such as:/admin– Admin panel/login– Personal accounts/cart– Shopping carts/search– Site search results/promotions– Outdated offers/compare,/favorites,/captcha
Examples:
Block a single page:
Code:
User-agent: *
Disallow: /contact.htmlBlock an entire section:
Code:
User-agent: *
Disallow: /catalog/Allow only one folder:
Code:
User-agent: *
Disallow: /
Allow: /catalog/
How to Block Files, Scripts & Parameters
You can also block indexing of specific files, scripts, or tracking parameters like UTM tags.Examples:
Block file types (e.g., images):
Code:
User-agent: *
Disallow: /*.jpgBlock a folder:
Code:
User-agent: *
Disallow: /images/Allow only one file in a folder:
Code:
User-agent: *
Disallow: /images/
Allow: /images/logo.jpgBlock scripts:
Code:
User-agent: *
Disallow: /plugins/*.jsBlock UTM tags:
Code:
User-agent: *
Disallow: *utm=
Clean-Param: utm_source&utm_medium&utm_campaign
How to Use Meta Tags Instead of Robots.txt
If you prefer not to use robots.txt, you can add a meta tag directly inside your HTML <head> section.Example 1 – Block all crawlers:
HTML:
<meta name="robots" content="noindex, nofollow">Example 2 – Full restriction:
HTML:
<meta name="robots" content="none">Meta tag options explained:
- none - No indexing or following links
- noindex - Block content indexing
- nofollow - Block link crawling
- index - Allow content indexing
- follow - Allow link crawling
Tip: You can mix rules like noindex, follow to block content but still let search engines follow links.
Common Robots.txt Mistakes
Even small syntax errors can cause major indexing issues. Watch out for these: Missing blank lines between rules Uppercase letters in directives Conflicting rules (logical errors) Forgetting Disallow: directive Always test your robots.txt using Google Robots Testing Tool or Yandex.Webmaster.
Quick Cheat Sheet
To block everything → use robots.txt with Disallow: / To block individual sections → specify their paths To block via HTML → use <meta name="robots"> To prevent crawler overload → close scripts, sessions, UTM tags To allow only one bot → combine Allow and Disallow rules To verify → use tools like Linkbox or Google Index Checker

Blocking your site or pages from search engines is simple - but must be done carefully.
