What are these bots?
They are a type of software used by search engines to delete new content from the internet for indexing purposes.
They perform the following tasks:
Visit web pages that you've linked to
Check your HTML code for errors
They save what web pages you're linking to and see what web pages link to your content
They index your content
However, some bots are malicious and search your site for email addresses and forms that are usually used to send you unwanted messages or spam. Others even look for security loopholes in your code.
What is needed to block web crawlers?
Before using the .htaccess file, you need to check the following things:
1. Your site must be running on an Apache server. Nowadays, even those web hosting companies half decent in their job, give you access to the required file.
2. You should have access to the raw server logs of your website so that you can locate what bots have been visiting your web pages.
Note there is no way you'll be able to block all harmful bots unless you block all of them, even those you consider to be helpful. New bots come up every day, and older ones are modified. The most efficient way is to secure your code and make it hard for bots to spam you.
Identifying bots
Bots can either be identified by the IP address or from their "User Agent String," which they send in the HTTP headers. For instance, Google uses "Googlebot."
You may need this list with 302 bots if you already have the name of the bot that you would like to keep away using .htaccess
Another way is to download all the log files from the server and open them using a text editor. Their location on the server may change depending on your server's configuration. If you cannot find them, seek assistance from your web host.
If you know what page was visited, or the time of visit, it's easier to come with an unwanted bot. You could search the log file with these parameters.
Once, you've noted what bots you need to block; you can then include them in the .htaccess file. Please note that blocking the bot isn't enough to stop it. It may come back with a new IP or name.
