Tip #1: Use Anti-Spam Comment Plugins

Using WordPress plug-ins to eradicate spam can help you sort out real comments from spam. Website plug-ins like Akismet can help you manage comments without going through them one by one. The note “Awaiting Moderation” will not appear for comments detected as spam.

There are times when real comments fall under spam and vise-versa. If this happens, contact the customer service of the plug-in that you use.

Tip #2: Think Twice on Allowing HTML Tags

HTML tags provide an opportunity for spammers to link from your site to theirs. Some webmasters prefer not to have any kind of HTML tags, but some allow bold and italics tags. But if you feel the need to include <a href> tag, you can still do so by adding rel=”nofollow”.

To code a no follow attribute to an html code, simple type in rel=”nofollow” after the closing quotation mark of the URL. See sample below:


Adding nofollow attribute is another way of commanding search engines not to follow the links on your page. In fact, it can even decrease the rank of target keywords used by spammers to connect to their site.

Google allows webmasters to add rel=”nofollow” if they are concerned of the following:

  • Untrusted Content

  • Paid Links

  • Crawl Prioritization

Tip #3: Do Not Activate Auto Approve

Another way to prevent spam is to put all new comments in moderation where you’ll have to approve every new comment. Although time-consuming it is a surefire way to make sure every comment that appears on your site is spam-free.

You can also use CAPTCHAs as well to moderate comments. However, this may not be a very effective technique these days. Some marketing companies that use black hat SEO strategies may hire online freelancers to unlock CAPTCHA codes and post comments.

Below is a sample of a form to send comments with CAPTCHA verification.

Website managers should always visit the comments page every once in awhile. While it is impossible to stop all spammers from sending spammy feedback, you can prevent them from hurting your business website. Thus, protecting the site from spammers means protecting the business itself.
