Combat WordPress comment spam with these tips and tools

Why You Need to Deal with Comment Spam in WordPress?

Internet is full of spam bots that automatically spread links for nefarious websites in the form of comment spam. The purpose of these spam comments is to get ranked in search engines and also to get accidental clicks from unsuspecting visitors.

But not all comment spam is submitted by bots. There are actual human submitted spam comments as well. These off-topic and poorly written comments are harder to catch and often contain links to third-party websites.

If you are not monitoring your website and these comments get published, then both your actual users and search engines will be able to see them.

This affects your website’s reputation. Users would consider your website to be a low quality or spam website.

Search engines can also mark your website as unsafe if they found links to websites that distribute malware and viruses.

That being said, let’s see how you can combat comment spam effectively, so that you spend less time worrying about spam and more time on growing your online business.

1. Turn on Comment Moderation in WordPress

Let’s first make sure that no comment on your website is published without your approval. This step will ensure that comments don’t bypass any filters, and it will also give you full control on which comments appear on your website.

This solution is highly recommended for business websites such as law firms, accounting, etc.

Head over to the Settings » Discussion page inside WordPress admin area. Next, scroll down to the ‘Before a comment appears’ section and check the box next to ‘Comment must be manually approved’ option.

Akismet is an anti-spam plugin that comes pre-installed with WordPress. It filters all WordPress comments on your website through their anti-spam database and catches the most common types of spam comments.

Akismet is available as a free plugin, but you’ll need to signup for their API key. You can get it free for a personal blog or a small website.

While Akismet is able to catch a lot of spam comments, it cannot stop spammers from accessing your website. Too many requests from spammers to submit comments can slow down your website and affect performance.

This is where Sucuri comes in. It is the best WordPress firewall plugin that allows you to block suspicious requests before they even reach your website.

They can prevent automated bots and scripts from submitting comments. This reduces the load on your servers and the number of spam comments you receive.

4. Using Honeypot to Catch Spam Bots

ReCAPTCHA is an advanced form of CAPTCHA, which is a technology used to differentiate between robots and human users. CAPTCHA is an acronym for “Completely Automated Public Turing test to tell Computers and Humans Apart”.
