The primary is thru robots.txt.
This can be a file that sits on the root of your internet server. Often, you might 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 web site:
Disallow Googlebot From Your Server
If, for some purpose, you wish 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 wish to use this code to maintain your web site from being listed in any respect.
Don’t use this on a whim!
Have a particular purpose for ensuring you don’t need bots crawling your web site in any respect.
For instance, a typical situation is wanting to maintain your staging web site out of the index.

Disallowing All Bots From Your Server

Consumer-agent: *
Disallow: /

Utilizing Each Disallow In Robots.txt And Noindex On The Web page
Google’s John Mueller has acknowledged you shouldn’t be utilizing each disallow in robots.txt and noindex on the web page itself.
When you do each, Google can not crawl the web page to see the noindex, so it may probably nonetheless index the web page anyway.
This is the reason it’s best to solely use one or the opposite, and never each.

Each web page in your web site can be blocked perpetually till you alter it.

You couldn’t keep in mind the precise right path initially, so that you went by means of the file and winging it.

If you wish to block a specific user-agent however you don’t know the identify of that user-agent, that’s an issue.
Relatively than utilizing the identify you suppose you keep in mind, perform some research and work out the precise identify of the user-agent that you just want.
If you’re attempting to dam particular bots, then that identify turns into extraordinarily vital in your efforts.
