Ask What does the compulsory robots.txt code for domain redirection?

[Brajet]

The robots.txt file is used to control search engine crawler access, but it does not perform domain redirection. For redirection, you need to use server-side methods like .htaccess on Apache or server rules in NGINX. However, you can use robots.txt to prevent indexing of the old domain while the redirection is handled elsewhere. For example, adding:

makefile
Copy code
User-agent: *
Disallow: /

blocks all crawlers from accessing the old site. Meanwhile, a 301 redirect in .htaccess (e.g., Redirect 301 / https://newdomain.com/) should be used to properly redirect users and crawlers. While robots.txt aids SEO management during transitions, it cannot handle redirection alone. Proper redirection ensures a smooth user experience and preserves search engine rankings during a domain move.

There's no mandatory robots.txt code just for domain redirection. Robots.txt is about crawler behavior, not about forwarding visitors or search bots. If your old domain redirects fully to a new one, the redirect rule is handled by your hosting or DNS setup, not robots.txt. A simple open robots.txt file is enough so crawlers can follow the redirect easily without blocking access or losing index signals.

The robots.txt file is used to guide search engines, but for domain redirection, it's not compulsory. Some people use it to block search engines from crawling the old domain during the redirect process. It can help avoid duplicate content issues. But if you've set up a proper 301 redirect, search engines will follow that without needing robots.txt. So, it's useful but not always necessary for redirection.
