A robots.txt file is a plain text document placed at the root of your website (e.g., www.example.com/robots.txt) that instructs search engine crawlers on which parts of your site they can or cannot access. It serves as a guide to manage crawler behavior, helping to optimize your site’s visibility and performance in search engine results.
Purpose & Benefits of robots.txt
1. Control Over Crawling
By specifying directives, you can prevent search engines from indexing certain parts of your site, such as admin pages or duplicate content, ensuring that only relevant pages appear in search results.
2. Optimized Crawl Budget
Search engines allocate a specific crawl budget to each site. By directing crawlers away from less important pages, you ensure that they focus on indexing your most valuable content, enhancing SEO efficiency.
3. Protection of Sensitive Information
You can restrict crawlers from accessing confidential directories or files, adding an extra layer of security to your website.
Examples of robots.txt Implementation
Example 1: Blocking All Crawlers from a Specific Folder
User-agent: * Disallow: /private/
This directive prevents all crawlers from accessing the /private/ directory.
Example 2: Allowing Specific Files in a Disallowed Folder
User-agent: * Disallow: /images/ Allow: /images/public.jpg
Here, crawlers are disallowed from accessing the /images/ directory except for public.jpg.
Example 3: Specifying Sitemap Location
Sitemap: https://www.example.com/sitemap.xml
This line informs crawlers about the location of your sitemap, aiding in better site indexing.
Best Practices for robots.txt
1. Place in Root Directory
Ensure the robots.txt file is located in the root directory of your website to be recognized by crawlers.
2. Use Wildcards Judiciously
Wildcards like * and $ can be used to match patterns, but should be applied carefully to avoid unintended blocking of content.
3. Regular Testing and Validation
Utilize tools like Google Search Console to test your robots.txt file, ensuring that it’s correctly configured and doesn’t block essential content.
