A Robot.txt file is a simple text file that website owners place in the root directory of their site. It serves as a set of instructions for search engine crawlers (also known as bots or spiders) on which parts of the website they should or shouldn’t crawl.
How It Works
The robots.txt
file works by specifying directives for search engine crawlers. For example:
User-agent: *
Disallow: /private/
This tells all search engine crawlers (User-agent: *
) not to access the /private/
directory of your site.
Key Points to Remember
robots.txt
does not guarantee that a page won’t be indexed.- It only advises search engines on crawling behavior.
- Some bots ignore the
robots.txt
file, especially malicious ones.
Does a Robots.txt File Prevent Indexing?
Common Misconceptions
Many website owners think that adding a Disallow
directive in robots.txt
will stop pages from appearing in search results. This is incorrect. The robots.txt
file only prevents crawling, not indexing. If a page is linked elsewhere, search engines may still index it even if they don’t crawl its content.
When Can a Page Be Indexed Despite Being Blocked?
- If another website links to it, search engines can still list it.
- If the page was previously crawled, it may remain in search results.
- If metadata allows it, such as an
<meta name="robots" content="index">
tag.
The Right Way to Prevent Indexing
If you truly want to prevent indexing, use meta robots tags or password protection:
<meta name="robots" content="noindex, nofollow">
Or restrict access at the server level (e.g., .htaccess
for Apache).

/temp/
