What is robots.txt?

Robots.txt is a small plain-text file that lives in the root folder of your website, at an address like https://yourdomain.com/robots.txt. Its job is to tell search-engine crawlers which parts of your site they are welcome to visit and which parts they should leave alone. When a crawler such as Googlebot arrives, checking this file is usually the first thing it does.

The file follows the Robots Exclusion Protocol, a long-standing agreement that the major search engines respect. Each robots.txt file is built from one or more groups of rules. A group starts by naming a crawler with a User-agent line, then lists the paths that crawler may or may not request. It is a set of polite instructions rather than a lock, so it works best for guiding well-behaved bots, not for keeping secrets.

How robots.txt works

Before a crawler fetches your pages, it downloads your robots.txt file and reads the rules that apply to it. Each rule is a single line made up of a directive and a value. Here are the directives you will actually use:

  • User-agent — names the crawler a group of rules applies to. * means every bot.
  • Disallow — a path that the named crawler should not request. Disallow: / blocks the whole site.
  • Allow — an exception that opens a path back up, even inside a blocked folder.
  • Sitemap — the full URL of your XML sitemap so crawlers can find your pages faster.

A crawler matches paths from left to right, and the most specific rule wins. In the example below, the whole /private/ folder is closed off, but one file inside it stays open.

Example
User-agent: *
Disallow: /private/
Allow: /private/public-notice.html

Sitemap: https://yourdomain.com/sitemap.xml

One line worth remembering: robots.txt controls crawling, not indexing. It asks a bot not to fetch a page. If you need a page kept out of search results, use a noindex meta tag instead, which we explain further down.

Why robots.txt matters for SEO

Search engines give every site a rough crawl budget — the number of pages they will fetch in a given period. A tidy robots.txt file helps them spend that budget on the pages you actually want ranked. This matters more as a site grows and picks up thin or duplicate URLs that add nothing to search results.

  • Focus crawl budget. Keep bots away from cart, filter and internal search pages so they reach your real content sooner.
  • Reduce server load. Blocking heavy or endless URL patterns stops aggressive crawling from slowing your site down.
  • Point to your sitemap. A sitemap line helps engines discover new and updated pages quickly.
  • Cut duplicate crawling. Steering bots away from tag archives and print versions reduces wasted requests.

Used carefully, robots.txt is a quiet SEO win. Used carelessly, a single wrong line can hide your best pages, so it pays to check your rules before you publish them.

Common robots.txt mistakes

Most robots.txt problems come from a few repeat offenders. Watch out for these:

  • Blocking the entire site by accident. A stray Disallow: / left over from a staging setup can wipe you out of search.
  • Expecting it to hide private data. Anyone can open your robots.txt, so listing a secret folder there simply advertises it. Use passwords or server rules for anything sensitive.
  • Blocking CSS and JavaScript. Google needs these files to render your pages. Blocking /wp-includes/ or asset folders can hurt how your pages are understood.
  • Assuming Disallow removes a page. A blocked URL can still appear in results if other sites link to it. Removing a page from search needs noindex, not Disallow.
  • Case and slash slips. Paths are case-sensitive, and /Folder is not /folder. A trailing slash also changes the match.
  • Putting the file in the wrong place. It only works at the domain root, never in a subfolder.

Robots.txt examples

Real files are usually short. Here are the patterns you will reach for most often — copy one as a starting point and adjust the paths to match your site.

Allow every crawler everywhere
User-agent: *
Disallow:
Block the whole site (useful for staging)
User-agent: *
Disallow: /
Block a few folders but allow the rest
User-agent: *
Disallow: /cart/
Disallow: /checkout/
Disallow: /search/

Sitemap: https://yourdomain.com/sitemap.xml
Allow Googlebot, block a specific bot
User-agent: Googlebot
Disallow:

User-agent: AhrefsBot
Disallow: /
Keep an AI scraper out of your content
User-agent: GPTBot
Disallow: /

User-agent: *
Disallow:

WordPress robots.txt example

WordPress creates a virtual robots.txt automatically, so a fresh install already has one even if there is no file on the server. It is basic, but for most sites it is enough. If you want more control, you can replace it with your own rules. A sensible starting point for a WordPress site looks like this:

robots.txt for WordPress
User-agent: *
Disallow: /wp-admin/
Allow: /wp-admin/admin-ajax.php

Sitemap: https://yourdomain.com/wp-sitemap.xml

Notice that /wp-admin/ is blocked while admin-ajax.php stays open, because some themes and plugins rely on it to load content. Avoid blocking /wp-includes/ or your uploads folder — doing so can stop Google from rendering your pages properly. If you use an SEO plugin like Yoast, Rank Math or All in One SEO, each one has a built-in robots.txt editor, so you can paste these rules straight into the dashboard without touching FTP.

Robots.txt best practices

  • Keep it simple. Only add rules you understand. A short, clear file is easier to maintain and less likely to break.
  • Always include your sitemap. One Sitemap line helps search engines find everything worth crawling.
  • Never block CSS, JS or images you want rendered. Blocking them can change how your pages are judged.
  • Use noindex for pages you want out of search. Reach for robots.txt to manage crawling, not to remove indexed pages.
  • Match paths carefully. Remember that rules are case-sensitive and that a trailing slash matters.
  • Test before and after every change. A quick check saves you from a costly mistake.
  • Review it now and then. As your site changes, old rules can quietly block the wrong things.

How to upload robots.txt

Once you have generated your rules above, getting the file live takes only a minute. The exact steps depend on how you manage your site:

  • Save the file. Copy your rules into a new plain-text file named exactly robots.txt — all lowercase, nothing extra.
  • Upload it to the root. Using FTP or your hosting file manager, place it in the top-level folder (often public_html) so it opens at yourdomain.com/robots.txt.
  • On WordPress, use a plugin. Yoast, Rank Math and AIOSEO each include a robots.txt editor, so you can paste and save your rules without any file transfer.
  • Confirm it works. Visit yourdomain.com/robots.txt in your browser. If your rules show up, you are done.

How to test robots.txt

Testing takes seconds and catches mistakes before search engines act on them. A few quick ways to check your file:

  • Open it directly. Load yourdomain.com/robots.txt and read the rules. It should return the file, not a 404.
  • Use Google Search Console. The URL Inspection tool tells you whether a specific page is blocked, and Search Console reports any robots.txt errors it finds.
  • Try an online tester. Free robots.txt testers let you paste your rules and a sample URL to see whether it would be crawled.
  • Re-check after every edit. Search engines cache the file, so confirm the new version is live and test the paths you care about.

Frequently asked questions

What is a robots.txt file?

A robots.txt file sits at the root of your website and tells search-engine crawlers which pages or sections they are allowed or not allowed to visit. It follows the Robots Exclusion Standard and is read by bots before they crawl your site.

Does robots.txt actually block crawlers?

Well-behaved crawlers like Googlebot and Bingbot respect robots.txt rules. However, it is not a security measure. Malicious bots may ignore the file entirely. Use server-level access controls or password protection for truly private content.

What does User-agent: * mean?

The asterisk * is a wildcard that matches all crawlers. Rules under this block apply to every bot that reads the file, unless a more specific user-agent block overrides them.

Where do I upload robots.txt?

Place the file at the root of your domain, for example https://yourdomain.com/robots.txt. It must be accessible at exactly that URL for crawlers to find it.

Can I create a robots.txt file just for Googlebot?

Yes. Add a dedicated block that starts with User-agent: Googlebot and give it its own Allow and Disallow lines. Google's crawler follows the most specific matching block, so those rules apply to Googlebot while your User-agent: * block still covers every other crawler. This tool lets you add per-crawler blocks so you can, for example, let Googlebot into a folder you block for everyone else.

How do I create a custom robots.txt file for Blogger?

Build your rules with the generator above, then in your Blogger dashboard go to Settings → Crawlers and indexing → Enable custom robots.txt, and paste the generated file. A custom robots.txt for Blogger (Blogspot) lets you control which pages Googlebot crawls, block search and label pages, and point crawlers to your sitemap for faster, cleaner indexing.

How do I add a robots.txt file to WordPress?

WordPress serves a virtual robots.txt by default. To use a custom one, generate your rules here and either upload a robots.txt file to your site root via FTP, or paste the rules into your SEO plugin — Yoast, Rank Math and AIOSEO all include a robots.txt editor. This gives you full control over crawling rules and sitemap discovery for your WordPress site.

Will robots.txt remove my page from Google?

No. A Disallow rule only asks a crawler not to fetch the page. If other sites link to that URL, it can still show up in results, often without a description. To keep a page out of search, add a noindex meta tag or use the removal tool in Search Console, and make sure the page is not blocked so Google can actually read the noindex.

How often do search engines check robots.txt?

Crawlers cache the file, so changes are not picked up instantly — Google typically refreshes it within about a day. Because of this, always confirm your new version is live and give it a little time before assuming a rule has taken effect. Google also reads only the first 500KB of the file, which is far more than a normal robots.txt needs.

What is the difference between robots.txt and a meta robots tag?

Robots.txt works at the site level and controls crawling — whether a bot may request a URL at all. A meta robots tag (or the X-Robots-Tag header) works at the page level and controls indexing — whether a page may appear in search. Use robots.txt to manage crawl budget, and use noindex when you specifically want a page kept out of results.
