What Is Robots.txt ?
A robots.txt file is a text file that webmasters create to instruct web robots, particularly Search Engine robots, on how to crawl pages on their website.
This file serves as a set of instructions that specify which pages or sections should be crawled and indexed and which should be ignored by Search Engine Bots. It helps website owners control the behavior of search engine crawlers, manage access, limit indexing to specific areas, and regulate crawling rates.
The robots.txt file is placed in the root directory of a website and contains directives for bots indicating which web pages they can and cannot access. It is a voluntary standard used by websites to guide web crawlers and influence the indexing process, but compliance with its directives is not mandatory.
Malicious bots can use the robots.txt file to determine which pages to visit, although some archival sites may ignore these instructions. The standard was proposed in 1994 and has become a widely accepted practice for webmasters to communicate with web robots about crawling permissions.
How to Create a Robots.txt file:
To create a robots.txt file, follow these general steps:
Access the Root Directory: You must have access to the root directory of your domain where the robots.txt file will be placed.
Use a Text Editor: Open a plain text editor like Notepad (Windows) or TextEdit (Mac) to create the robots.txt file.
Create the File: In the text editor, specify the instructions for web robots, indicating which pages they can crawl and which they should not access. The file follows a specific format and syntax.
Save the File: Save the file as "robots.txt" in the root directory of your domain, for example, www.yourdomain.com/robots.txt[2].
Upload the File: Once created, upload the robots.txt file to your website's root directory. The process of uploading may vary based on your site's file structure and hosting environment.
Remember, the robots.txt file is crucial for guiding web robots, especially search engine crawlers, on how to interact with your website, determining which pages they can crawl and index. By creating and optimizing your robots.txt file correctly, you can enhance your website's SEO and control how search engines interact with your content.
what are some common directives used in robots.txt
According to the search results, some of the most common directives used in a robots.txt file include:
Disallow: This directive tells search engine bots not to crawl the specified URL or directory. For example, "Disallow: /directory" would prevent bots from crawling that directory.
Allow: This directive overrides a previous "Disallow" directive, allowing bots to crawl the specified URL or directory. For example, "Allow: /directory/page" would allow bots to crawl that specific page even if the parent directory was disallowed.
User-agent: This directive specifies which bot or crawler the following instructions apply to. Using "*" applies the directives to all bots.
Sitemap: This directive provides the location of the website's sitemap, which helps search engines discover and crawl pages more efficiently.
NoIndex: This unofficial directive (not officially supported by Google) instructs bots not to index the specified pages, even if they are crawled.
$: This symbol is used to indicate the end of a URL, allowing more specific blocking of file types like ".jpg$".
#: This allows adding comments to the robots.txt file, which can help document the purpose of different directives.
The most common directive is the "Disallow" directive, which is used to prevent search engine bots from crawling specific pages or directories on a website.
How to Test if Robots.txt is Working Correctly:
Based on the search results, here are the key steps to test if a robots.txt file is working correctly:
Use an Online Robots.txt Tester Tool: The search results mention several free online tools that allow you to test and validate your robots.txt file, such as the ones from Tame the Bots SEO Site Checkup,Logeix,and Ryte.
These tools let you enter a URL and see if specific pages are allowed or blocked by the robots.txt directives.
Check Crawlability of URLs: Use the tester tools to check the crawlability status of specific URLs on your website. The tools will indicate whether the URLs are allowed or blocked by the robots.txt file.
Validate Robots.txt Syntax: The tools can also help you validate the syntax and formatting of your robots.txt file to ensure it is properly structured and the directives are correctly written.
Test Against Different User Agents: Some tools allow you to test the robots.txt file against different user agents, such as Googlebot, to see how various crawlers would interpret the directives.
Review Suggested Improvements: For Shopify stores, some tools may provide recommendations on additional rules to add to the robots.txt file to optimize crawling and indexing.
Monitor Crawl Errors: Regularly check your website's crawl error reports in Google Search Console or other webmaster tools to identify any issues with the robots.txt file that may be preventing search engines from accessing important pages.
By using these testing tools and following best practices, you can ensure your robots.txt file is configured correctly and effectively controlling how search engines crawl and index your website.
How to Submit a Sitemap to Google Using Robots.txt:
Based on the search results, here are the steps to submit a sitemap to Google using the robots.txt file:
Locate your website's robots.txt file: The robots.txt file should be located in the root directory of your website, for example, www.example.com/robots.txt[2]
Add the sitemap directive: In the robots.txt file, add a line that specifies the location of your sitemap. The directive should look like this:
Sitemap: https://www.example.com/sitemap.xml
Replace "https://www.example.com/sitemap.xml" with the actual URL of your sitemap.
Save and upload the robots.txt file: Save the robots.txt file with the sitemap directive and upload it to the root directory of your website.
Verify the robots.txt file: Use an online robots.txt tester tool to ensure the robots.txt file is correctly configured and the sitemap directive is properly formatted.
Monitor the sitemap submission: Check the Google Search Console's "Sitemaps" report to see if your sitemap has been successfully submitted and indexed. The report will show the status of your sitemap submission and any errors that need to be addressed.
By including the sitemap directive in your robots.txt file, you are informing search engines, particularly Google, about the location of your sitemap. This helps search engines discover and crawl your sitemap more efficiently, leading to better indexing of your website's content.
How to Prevent Specific Pages From Being Crawled by Search Engines Using Robots.txt
To prevent specific pages from being crawled by search engines using robots.txt, you can follow these steps:
Access Your Robots.txt File: Locate and access your website's robots.txt file, which is typically found in the root directory of your domain.
Add Disallow Directives: In the robots.txt file, use the "Disallow" directive to specify the pages or directories you want to block search engines from crawling. For example:
User-agent: *
Disallow: /page-name
Disallow: /folder-name/
Replace "/page-name" and "/folder-name/" with the URLs of the specific pages or directories you want to prevent search engines from crawling.

Save and Upload the File: Save the changes to your robots.txt file and upload it to the root directory of your website.
Test Your Robots.txt: Use tools like the tester tool in Google Search Console to verify that the robots.txt file is correctly configured and that the specified pages are blocked from being crawled.
By adding "Disallow" directives for specific pages or directories in your robots.txt file, you can effectively prevent search engines from crawling and indexing those areas of your website. This method helps you control which content is visible to search engines and can be useful for protecting sensitive information or preventing duplicate content issues.
