1. Use a WordPress Security Plugin

Some popular CDNs include:
- Cloudflare
- Sucuri
- Akamai
4. Monitor Your Website Traffic

Best Practices for Blocking Spam Bots in WordPress
Here are a few best practices for blocking spam bots in WordPress:
- Keep your WordPress core and plugins up to date. WordPress updates often include security patches that can help to protect your website from spam bots.
- Use strong passwords for all of your WordPress accounts. This will make it more difficult for spam bots to brute-force their way into your website.
- Enable two-factor authentication for your WordPress accounts. This will add an extra layer of security to your website.
- Disable XML-RPC. XML-RPC is a feature of WordPress that is often used by spam bots to attack websites. You can disable XML-RPC without impacting the functionality of your website.
- Use a CAPTCHA on your login and contact forms. This will help to prevent spam bots from submitting forms on your website.
How to Block Spam Bots in WordPress Without Losing Traffic
It’s important to note that some of the methods described above, such as using a CAPTCHA on your login and contact forms, can have a negative impact on user experience. This can lead to a decrease in traffic to your website.
However, there are a number of ways to block spam bots in WordPress without losing traffic. Here are a few tips:
- Use a honeypot plugin. A honeypot plugin creates fake forms and fields on your website that are designed to attract spam bots. This can help to protect your legitimate forms from being spammed.
- Use a rate limiter. A rate limiter plugin can limit the number of requests that a user can make to your website in a certain period of time. This can help to prevent spam bots from overloading your server.
- Use a web application firewall (WAF). A WAF is a security tool that can help to protect your website from a variety of attacks, including spam attacks.
How to Identify and Block Spam Comments
One of the most common ways that spam bots attack WordPress websites is by posting spam comments.
Here are a few tips for identifying and blocking spam comments:
- Use a WordPress comment moderation plugin. A comment moderation plugin can help you to identify and block spam comments. These plugins typically use a variety of methods to identify spam, such as checking for known spam keywords and phrases, and analyzing the commenter’s IP address.
- Manually review all comments before they are published. This is the most time-consuming method, but it is also the most effective.
- Enable comment approval. This will require all comments to be approved by you before they are published.
How to Protect Your WordPress Login Page from Spam Bots
Spam bots can also attack WordPress websites by attempting to brute-force login to the admin area.
Here are a few tips for protecting your WordPress login page from spam bots:
- Use a strong password for your WordPress admin account.
- Enable two-factor authentication for your WordPress admin account.
- Use a WordPress login lockdown plugin. A login lockdown plugin can limit the number of failed login attempts before the user is locked out.
- Change the default WordPress login URL. This will make it more difficult for spam bots to find your login page.
