The primary is thru robots.txt.

This can be a file that sits on the root of your internet server. Often, chances are you’ll not have one by default, and you would need to create one.

These are just a few extremely helpful robots.txt codes that you should use to dam most spiders and bots out of your website:

Disallow Googlebot From Your Server

If, for some motive, you need to cease Googlebot from crawling your server in any respect, the next code is the code you’ll use:

Consumer-agent: Googlebot
Disallow: /

You solely need to use this code to maintain your website from being listed in any respect.

Don’t use this on a whim!

Have a selected motive for ensuring you don’t need bots crawling your website in any respect.

For instance, a standard situation is wanting to maintain your staging website out of the index.

You don’t need Google crawling the staging website and your actual website since you are doubling up in your content material and creating duplicate content material points consequently.

If you wish to maintain all bots from crawling your website in any respect, the next code is the one it would be best to use:

Consumer-agent: *
Disallow: /

Google’s John Mueller has acknowledged you shouldn’t be utilizing each disallow in robots.txt and noindex on the web page itself.
