To create a robots.txt file for your website, follow these steps:
User-agent: [user-agent name] Disallow: [URL string not to be crawled]
The "User-agent" line specifies the search engine robots to which the instructions apply, and the "Disallow" line specifies which pages or directories should not be crawled by the search engine.
For example, if you want to disallow all search engine robots from crawling a specific directory on your website, you would use the following syntax:
User-agent: * Disallow: /directory/
If you want to allow all search engine robots to crawl your entire website, you would use the following syntax:
User-agent: * Disallow:
Note that the robots.txt file is not a guarantee that search engines will not crawl or index specific pages of your website. Some search engines may ignore the robots.txt file, and others may accidentally crawl pages that are disallowed.
