Comments used to be the heart of blogging. Today they’re an active question, and many serious blogs have turned them off entirely. The reasoning has shifted along with how readers behave online and how spam has evolved over the past decade. This post lays out the honest case for each side, so you can decide what actually fits your blog rather than following a rule someone else set in 2012.

Three options for blog feedback: open comments, no comments, and email-only response

What comments used to do

Through the late 2000s and 2010s, blog comments were the primary engagement signal available to a blogger. They served several purposes at once:

  • Showed that the blog was alive and being read.
  • Gave readers a way to respond directly to what they’d just read.
  • Built community around bloggers who consistently replied.
  • Generated additional content through replies and discussion.
  • Signaled social proof to new readers landing on a post.

The model worked well when blogs were the primary social platform for reading and writing online, before that role got split across a dozen other apps.

What changed

Several shifts happened roughly at once, and together they explain why the calculus looks different now:

1. Engagement moved to social platforms

Readers who would once have left a comment now reply on X, share in Slack groups, or send a DM directly to the writer. The comment box on the blog itself sees far less use as a result.

2. Spam became overwhelming

Modern comment spam is automated, sophisticated, and high volume. Without Akismet or an equivalent tool, a typical WordPress blog can attract hundreds of spam comments per day, and moderating that volume becomes a real time cost few bloggers budgeted for. If you do keep comments on, a proper moderation strategy is what keeps that cost from spiraling.

3. Comment quality dropped

The comments that do get through often add little beyond “Great post!” or “Thanks for sharing!” Genuinely useful comments, meaning actual discussion, additions, or corrections, are rarer than they used to be.

4. Trolling and harassment increased

For some niches, comment sections became a liability rather than an asset. A 2025 study published in the journal New Media & Society found that exposure to hostile comment sections actively erodes reader trust in the surrounding content, not just in the commenters themselves. Personal blogs, opinion-driven blogs, and anything touching politics or social issues tend to attract the bad-faith commenters most likely to trigger that effect.

5. SEO benefit faded

Comments don’t help search rankings the way they once did back when comment count was treated as a rough proxy for engagement. Google’s systems have gotten considerably better at distinguishing meaningful engagement signals from raw comment quantity.

When comments still help

There are real cases where keeping comments on is the right call:

  • Discussion-driven topics. Philosophy, opinion, and controversial-but-substantive topics all benefit, since comments genuinely add to the post.
  • Community-led blogs. If part of the blog’s value is the community around it, comments function as infrastructure, not decoration.
  • How-to posts with troubleshooting. Readers ask specific questions that future readers benefit from seeing answered in place.
  • Niche technical blogs. Experts often add corrections and edge cases that improve the post over time.
  • You genuinely enjoy the conversations. If you reply to comments and it feels rewarding rather than draining, that’s reason enough to keep them.

When comments hurt

There are equally real cases where turning them off is the right call:

  • Solo bloggers without time to moderate. Unmoderated comment sections decay fast and start working against the blog.
  • Topics that attract bad-faith argument. Politics, parenting, and lifestyle choices are common flashpoints.
  • Blogs where most engagement already happens via email or social. In that case comments become an empty box that quietly signals “nobody’s reading.”
  • Visual blogs. Comments sitting below a photo or recipe often clutter the reading experience more than they add to it.
  • Bloggers who never reply. A one-sided comment section reads as abandoned, which is worse than having none at all.

The third option: closed comments, open email

A pattern many serious blogs have adopted sits between the two extremes: no comments, but a clear invitation to email instead.

At the bottom of each post: “Have a question or correction? Email me at [address]. I read every message.”

This works for a few concrete reasons:

  • Readers who genuinely want to respond will still do so. Casual commenters simply won’t bother.
  • You get higher-quality feedback overall, because emailing carries slightly more friction than commenting.
  • There’s no spam left to moderate at all.
  • There’s no empty comment section sitting there signaling low engagement.
  • You build direct email relationships with your most engaged readers.

The trade-off is that you lose the visible “this post got 47 comments” social proof. For most modern blogs, that particular signal mattered more back in 2012 than it does today.

Three comment systems compared: traditional WordPress comments, no comments with email, and third-party hosted

If you keep comments on

A few best practices make a real difference here:

  • Use Akismet or a similar filter. It stops the vast majority of spam automatically.
  • Hold first-time commenters for moderation. This catches whatever the spam filter misses.
  • Close comments on old posts. WordPress can auto-close after 30, 60, or 90 days, which reduces spam and prevents stale threads from reopening.
  • Reply to early comments. The first two or three comments shape the tone of everything that follows. Reply substantively and others tend to match that.
  • Have a comment policy. Keep it brief and clear: “No personal attacks. No promotional links.”
  • Delete bad-faith comments without guilt. It’s your blog, and you get to set the standards for it.

If you turn comments off

A few best practices apply here too:

  • Add a clear contact email at the end of every post. Or link to a contact form if you’d rather not publish an address.
  • Mention that you read replies. It adds warmth and makes the invitation feel real.
  • Remove the empty “no comments” placeholder. Showing “0 Comments” looks worse than showing no section at all.
  • Don’t apologize for it. “Comments are closed” without further explanation is perfectly fine on its own.
Quick tip: If you switch to email-only feedback, create a dedicated folder or label for it right away. Reader replies scattered across a general inbox get missed, and a missed reply from an engaged reader is the one relationship this whole approach is meant to protect.

The third-party comment systems

Some blogs use Disqus, Commento, or similar hosted systems instead of native WordPress comments. The trade-offs are real in both directions:

  • Pro: better spam handling, social login, and threaded replies out of the box.
  • Con: third-party tracking, added page weight, and a dependency you don’t control.

The page-weight difference is larger than most bloggers expect. One independent performance comparison found a WordPress page with native comments loading at roughly 277KB total, while the same page with Disqus activated exceeded 1MB, on top of the tracking scripts Disqus loads for every visitor. For most blogs, native WordPress comments paired with Akismet beat Disqus on balance. The speed and privacy costs of Disqus tend to outweigh its UX gains at typical blog comment volumes, and page speed itself feeds into how Aurora and other performance-conscious themes are built to load quickly in the first place.

Migrating from comments to no comments

If your blog has years of existing comments and you want to close the section going forward, the transition is straightforward:

  1. Don’t delete your existing comments. They contribute to page content and to SEO.
  2. Use WordPress’s setting to disable new comments on all existing posts at once.
  3. Set the default for new posts to “comments closed.”
  4. Add the email contact line to your post template.
  5. Optionally, add a one-paragraph note explaining the change, though this isn’t required.

The transition itself is smooth. Old comments remain visible exactly as they were, and new ones simply can’t be added on top of them.

What about SEO

The “comments help SEO” advice that circulated heavily around 2012 hasn’t held up well since. What actually matters now:

  • Engagement signals, such as time on page, return visits, and sharing.
  • Content quality itself.
  • Page speed.

Comments can help with the first of those, but a heavy comment load can hurt the third. Most blogs today see a neutral or slightly negative SEO impact from keeping comments open, which is a meaningful shift from the conventional wisdom of a decade ago.

There’s no universal right answer here

Comments helped early-internet blogs more than they help most modern ones. Keep them open if your blog is discussion-driven, community-focused, or already has a genuinely engaged commenter base. Turn them off if comments are dead, spam is overwhelming, or moderation has become a chore you dread. The strongest modern pattern for many blogs is no comments paired with a clear email contact: higher-quality feedback, no spam, and relationships built directly instead of in public. The “blogs need comments” assumption deserves a fresh look for every blog, on its own terms.
