It’s curious to say that not all bots are classified as ‘bad’. Some even have no bad intentions and serve for functions like indexing pages.
The bot is the catchall name for a software system that “pretends” to be human online.

• Comment spam – just like the name says, bots try to post spam comments, even for blog posts wherever comment posting is disabled!
• Sniffing for unsafe themes and plugins – A bot is attempting to access files on your web site.
• Indexing your web – A bot checks all of your pages just like the Google bot. This type of bots is usually operated by companies to gather your data/content for statistics, link profiles, etc.
• Server Memory – Each web-server has limited memory that is shared by all of the sites running thereon. Bad bots can reach server memory for a couple of minutes.
All these attacks generate often way more load on your web server than your regular visitor. The matter with WordPress, or the PHP code that is executed for each page view, is that it uses up memory (RAM). Before you recognize it, your website is down like every other site on the server. The advantage is to limit the number of requests on PHP files and to stay unwanted bots off your website.

Of course, if you wish your website to operate 24/7, the most effective factor would be to ask for help. Here are the items you will do to protect your WordPress website against bots.
5 Ways To Protect Your Website

1. Block dangerous bots
Bad bots may be blocked with the assistance of robots.txt file. This file consists of rules that each bot is supposed to obey, and one good thing you will do is instruct bots that pages on your WordPress website are out of limit. If a bot disobeys the rule and visits a page that’s excluded by the robots.txt file, it will be clear that it’s a bot with bad intentions. That is once it may be blocked by Blackhole for Bad Bots – a plugin with a clear and specific purpose.

Once you add a pattern into your robots.txt file that matches this one, bots can become simply noticed.
Another way to stay bad bots and spam bots off your website is to use the WordPress plugin AVH First Defense Against Spam. This plugin isn’t only effective to fight spam, it’s also a good way to block bad bots generally before they will “touch” your website.
2.Install WP Super Cache and use mod_rewrite for file caching
The easiest way to limit down the execution of PHP scripts is to use a cache plugin. A cache plugin creates a duplicate for every requested page or post and serves a cached file rather than recreating a page everywhere once more. WP Super Cache can be used for all WordPress websites, as a result of it is a well-maintained WordPress plugin that is extremely simple to put in. If you enter the WP Super Cache settings page, check the advanced tab for the three choices for caching: mod_rewrite, PHP and legacy caching. Do not ever use the PHP option, because some PHP code is involved whenever a file cache is made or requested. The mod_rewrite possibility is way better because the file cache is made, no PHP code is needed to serve the cached page or post to the shopper or browser.
3.Protect Your Website Against Brute Force Attacks (Login)
The login page is additionally a PHP script that wants memory for the execution While several CAPTCHA or JavaScript primarily based plugins still offer access to the PHP login script, Brute Protect can abandon a bot before most of the PHP code in WordPress is executed.
• Hide the wp-login.php page and wp-admin directory
Another effective technique is that the WP Cerber plugin. While using this plugin it’s possible to vary the WordPress login URL to something you prefer. Besides this feature, it is possible to “hide” the wp-admin directory still. The plugin works in multiple ways: The non-standard login URL does not work and also the IP address is blocked when some hacking attempts. WP Cerber may be a nice plugin for many websites with a group of users.
4.Htaccess File to Block Bad Bots
You can block one bad bot from accessing your WordPress by using an htaccess file. By using the htaccess example below, we will block a bot with the user-agent string evil bot.
RewriteEngine on
RewriteCond %{HTTP_USER_AGENT} ^evil
RewriteRule ^(.*)$ http://no.access/
The htaccess sample is checking the user-agent of the bad bot, and if it matches evil it’ll be redirected to a non-existing web site http://www.no.access. If you’d wish to block multiple bad bots from accessing your WordPress, use the [OR] operand within the htaccess file and add a line for every bad bot you wish to block, as shown within the below example.
RewriteEngine on
RewriteCond %{HTTP_USER_AGENT} ^evilbot [OR]
RewriteCond %{HTTP_USER_AGENT} ^spambot [OR]
RewriteCond %{HTTP_USER_AGENT} ^virusbot
RewriteRule ^(.*)$ http://no.access/
Bad bots are like pests; it is not possible to eliminate them. You will have the foremost in an extensive list of bad bots however new ones can seem daily. I wrote this text, you’ll effectively block bad bots that are dangerously moving your WordPress website and to not block all the bad bots on the web.
5. Show an easy 404 – NOT FOUND error exploitation .htaccess
The last protection for your WordPress website is critical due to some general mod_rewrite rule that exists for (almost) each WordPress installation. It is these two mod_rewrite conditions in your .htaccess file, that are created by WordPress if you set up SEO friendly permalinks.
# condition to check if a file doesn't exists
RewriteCond %{REQUEST_FILENAME} !-f
# condition to check if a directory doesn't exists
RewriteCond %{REQUEST_FILENAME} !-d
These mod_rewrite rules do not check if a requested file belongs to a post or pages. If a bad bot is sniffing on your web site for a few files (PHP, CSS, txt, js, png…) and also the file does not exist, WordPress can produce a 404 page. This page does not have a file cache and all the info queries and PHP code. Imagine memory is used, if a bot is attempting to access one hundred missing files during a single minute! The following rules can be used in my .htaccess file (paste it on top of the default code from WordPress) to stop the creation of unwanted 404 pages by WordPress:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} \.(jpg|jpeg|png|gif|bmp|ico|css|js|swf|htm|html|txt|php)$ [NC]
RewriteRule .* - [R=404]
</IfModule>
It is possible that; mod_rewrite condition and rule do not work for 100% in your specific case. It is better to undertake these crucial modifications on a test location. Check your log files often and take action if you’re thinking that some activity on your website isn’t normal. You would possibly be surprised how many bots threaten your web site daily. Website speed is crucial lately and it İs important to serve your pages quickly to your visitors.
