If you maintain a WordPress blog, you’ve probably given some thought to whether visitors should be allowed to comment on your posts. In theory, comments are a great way to encourage discussion, answer questions, and build relationships with readers.
Unfortunately, there’s another side to allowing comments, and that’s spam.
Over the years, I’ve managed numerous WordPress websites, and one of the more persistent problems has been the sheer volume of unwanted comments. Many are submitted automatically by bots, while others are written by people whose primary purpose is to promote a website, product, or service.
While there are tools available to help manage these submissions, I’ve generally found that disabling comments is the most practical option for many small business websites.
That doesn’t mean comments are without value. The question is whether the benefits justify the time and effort involved in managing them.
1. What Are the Benefits of Allowing Comments?
When visitors contribute meaningful comments, they can make an article more useful.
For example, someone reading a technical article might ask a question that wasn’t addressed in the original post. By responding, the author can clarify the subject and provide information that may benefit other readers.
Comments can also encourage discussions between readers, introduce different perspectives, and provide useful feedback about the content.
For websites with an established community, this interaction may be an important part of their appeal.
However, the nature of the website matters.
A technology blog, educational resource, or website built around a shared interest may benefit considerably from reader discussions. A local contractor, attorney, or other service business may have a very different audience.
Most visitors to a business website are looking for information about the company’s products or services. They may want to request an estimate, schedule an appointment, or simply find an answer to a question.
In these cases, an open commenting system may provide relatively little additional value.
2. The Problem With Comment Spam
One reason WordPress blogs attract spam is that commenting systems provide an opportunity for someone to publish content, often including a link to another website.
Spammers take advantage of this by submitting promotional messages, irrelevant comments, and links to websites they want to advertise.
Some messages are obvious. They contain unrelated advertisements, questionable links, or text that has nothing to do with the article.
Others are more difficult to identify. A comment might read, “Great article, thanks for sharing,” followed by a link to the commenter’s website. While this may appear harmless, the primary purpose is often to acquire a backlink rather than contribute to the discussion.
Automated spam protection can eliminate many of these submissions, but it isn’t always completely effective.
Even when spam is successfully filtered, someone may still need to review legitimate comments that were mistakenly flagged, delete unwanted submissions, and monitor the moderation queue.
For a busy business owner, this can become an unnecessary administrative responsibility.
There’s also the matter of what happens when comments are published without proper review. Spam links and misleading information can detract from the credibility of an otherwise useful article.
Google specifically identifies blog comment spam as a form of user-generated spam in its Search Spam Policies.
3. Do Blog Comments Improve SEO?
Years ago, there was considerable emphasis on encouraging comments because they added content to a page and were thought to improve search engine rankings.
The reality is more complicated.
Genuine comments can provide useful information, answer questions, and expand upon the original article. In some cases, that additional content may help search engines better understand the page or provide information that matches a visitor’s search.
However, simply having a large number of comments doesn’t make an article more authoritative or guarantee better rankings.
One well-written article containing useful, original information may provide considerably more value than a page with dozens of generic comments.
There’s also the issue of links included in comments.
Google recommends identifying links within user-generated content using the rel="ugc" attribute. This helps distinguish links contributed by visitors from those editorially provided by the website owner.
If your commenting system allows visitors to include links, it’s worth confirming that these are handled appropriately.
You can learn more from Google’s Guide to Qualifying Outbound Links.
My recommendation is not to enable comments simply because you believe they’ll improve your SEO. Focus first on creating informative articles that address the interests and questions of your intended audience.
4. Managing Comments With WordPress
If you decide to allow comments, WordPress includes several built-in options to help manage them.
These are available in the administration area under Settings > Discussion.
Some of the more useful options include:
- Manual Approval: Require comments to be reviewed before they’re published. This prevents unwanted submissions from appearing publicly without your approval.
- Previously Approved Commenters: Allow comments from previously approved contributors to appear without requiring approval each time. This can be convenient, although it provides less oversight than reviewing every submission.
- Comment Moderation: Hold comments for review based on the number of links or words and other criteria you specify.
- Registered Users Only: Require visitors to have an account before commenting. This may discourage some spam, but it also creates an additional step for legitimate visitors.
- Automatically Close Older Comments: Disable new comments after a specified number of days while retaining previously approved discussions.
- Pingbacks and Trackbacks: Control whether notifications from other websites are accepted. These can also attract spam and may be unnecessary for many business blogs.
For websites that receive relatively few legitimate comments, requiring manual approval is often a sensible starting point.
However, moderation doesn’t eliminate spam submissions. It simply prevents them from appearing publicly until they’ve been approved.
WordPress provides explanations of these options in its Discussion Settings Guide.
5. Should You Install an Anti-Spam Plugin?
There are several WordPress plugins and security services designed to reduce comment spam.
Some analyze submissions to identify suspicious content, while others use automated bot detection, hidden form fields, or verification challenges to discourage unwanted activity.
Akismet is one of the better-known WordPress anti-spam services, although it’s not the only available option.
Additional protection can be helpful, particularly for websites with active discussions. However, I’ve found that no single approach is consistently effective against every type of spam.
It’s also important to consider whether another plugin is necessary.
Every additional plugin introduces software that needs to be maintained, and some security plugins may duplicate functionality already provided by your hosting company or existing website protection.
Before installing anything, check whether the plugin is actively maintained, compatible with your version of WordPress, and appropriate for your particular needs.
If your website doesn’t benefit from allowing comments, disabling them may be a simpler and more effective solution than continually adding software to filter unwanted submissions.
6. How to Disable Comments in WordPress
If you’ve decided that comments aren’t necessary, WordPress makes it relatively easy to disable them.
To prevent comments on new blog posts:
- Log in to your WordPress administration area.
- Go to Settings > Discussion.
- Find the option labeled Allow people to submit comments on new posts, or similar wording depending on your WordPress version.
- Uncheck the option and save your changes.
It’s important to understand that this generally affects new posts. Comments may still be enabled on articles you’ve already published.
To disable comments on existing posts, go to Posts > All Posts. You can edit an individual article’s discussion settings or select multiple posts and use WordPress’s Bulk Edit feature to change the comment permissions.
Disabling new comments doesn’t automatically delete comments that have already been published. You can choose whether to retain those discussions or remove them.
Keep in mind that certain themes and plugins may provide their own commenting features or display settings, so the exact options may vary.
For additional instructions, see the official WordPress Comments Documentation.
7. You Can Still Encourage Customer Engagement Without Comments
One concern business owners sometimes have is that disabling comments will discourage visitors from contacting them or engaging with their content.
I don’t think that’s necessarily the case.
There are other ways to encourage communication that may be better suited to a small business website.
For example:
- Contact Forms: Provide visitors with a convenient way to submit questions or request additional information.
- Frequently Asked Questions: Use questions received from customers to develop helpful FAQ sections on your website.
- Social Media: Share your articles on Facebook, Instagram, LinkedIn, or other appropriate platforms where visitors can respond and participate in discussions.
- Email Newsletters: Keep interested customers informed about new articles, services, and useful resources.
- Customer Reviews: Encourage customers to share their experiences through appropriate review platforms, where their feedback can help prospective customers evaluate your business.
For many service businesses, these options provide more useful interaction than a public blog commenting system.
Personally, I would rather have a visitor contact a business directly with a legitimate question than submit a comment that may sit in a moderation queue for days.
Questions submitted by visitors can also inspire future blog articles or improvements to existing pages. In this way, businesses can benefit from customer feedback without maintaining an open commenting system.
Final Thoughts
WordPress comments can be useful, particularly for websites that encourage ongoing discussions and have an audience interested in participating.
However, for many small business websites, the benefits are limited when compared with the time required to manage spam, review submissions, and respond to comments.
My preference is generally to disable comments unless there’s a clear reason to provide them. I would rather concentrate on developing useful content, maintaining the website, and helping visitors find the information they’re looking for.
That doesn’t mean comments should always be avoided. If your website has an active community and readers regularly contribute meaningful information, a properly moderated commenting system may be well worth maintaining.
The important thing is to decide whether comments serve a useful purpose for your particular website.
A successful business blog doesn’t need hundreds of comments, or even a commenting system at all. What matters most is providing information that your visitors find useful and making it easy for them to contact you when they need assistance.
