How blog comments are good and bad for SEO

Blog comments are dying!

That’s the general feel around the blogging community. What used to be the number one way to connect with bloggers has now been put in the corner thanks to Twitter and Instagram. If I post a link to a blog post on Twitter, I’m more likely to get a reply on Twitter about it rather than on the blog post itself.

My personal belief is that this is down to the increase in content consumption on mobile devices. It’s a bit clunky to leave comments on a blog on a phone, it’s much easier to hit back and reply to the tweet!

Anyway, comments can have an effect on your SEO. So let’s look at the good things blog comments can have for your SEO!

How blog comments are good and bad for SEO

How blog comments help your SEO.

Word count.

Word count is an indication of quality, in-depth articles to Google. If you have blog comments, they add to the word count of your blog! This is even better if the comments are long, high quality, relevant and contain keywords!

The number of comments.

The more high quality comments your blog receives, the better it is for your blog! The ‘great post! :)’ comments are trash, so if you leave those types of comments on peoples blogs, please don’t! Help them out by leaving relevant comments that show you have actually read the post.


When you comment on someone else’s blog post, it creates a backlink to your site. Although these are no-follow links, they do carry some value.

All these things can have a negative impact on your SEO.

Off page SEO.

As above, commenting on someone else blog can be great for SEO. Not just in terms of the link, but the keywords you use could help boost your own rankings. Comment on content similar to yours so you can keep it relevant!

Now on to why comments can be bad for your SEO.


I’ve recently disabled and deleted the Commentluv plugin. I love the idea of it, it gives the commenter the chance to link back to a post so you can read it and give them some comment love! The only problem is:

  • This can be attractive to spammers
  • You can end up with irrelevant links on your blog
  • This links can become broken

Spam, low-quality comments.

As I said above, having short comments or low-quality comments could have a negative impact on your SEO. Feel free to delete any comments that do not add any value to your content!

Irrelevant links.

If you have a blog post about how to grow your blog, then a commenter links back to their beauty blog, or post about lipstick, this could have a negative impact on your blog too as it’s putting links to websites that are not on the same topic as your post. It can cause confusion as to what your blog post is about.

Similarly, you could hurt your own SEO of you are commenting on blog posts not within your niche. Try leaving a link to a relevant post on other peoples blogs to help both of you!

Broken links.

This is the challenge I have now – a blog that’s over 6 years old and has thousands and thousands of comments. Some of these blogs have since been deleted, leaving me with a broken link that pulls down the quality of my site in SEO terms. I’ve got around 1200 broken links to fix due to this. It’s slow going through them all!

So, there you have it. How you use comments can have both a positive and negative impact on your blogs SEO – are you using blog comments efficiently?

    I remember reading in one of your posts how broken links can be bad for our SEO, links leading to a blog that doesn’t exist anymore and while deleting those comments makes sense, I feel bad about deleting comments that mean something, you know meaningful comments from bloggers that don’t blog anymore but that used to leave me regular comments. I’m not sure I’ll delete those, but short comments with broken links and spam- definitely.

    I get some spam comments and it often takes me a lot of time to delete them. Plus, I have to regularly check my comment section and try to spot them because they often leave comments on my old posts. I’m slowly learning more about SEO (quite a lot of it thanks to your blog), and I’m trying to implement it into my blogging. If one is investing effort into blogging, it makes sense to look into SEO because that’s such a mayor part of how our blog will do.

    I always worry about spam comments and people leaving links on my blog. After reading your post, I feel justified about this that my worries aren’t for naught. I have been trying to be more diligent about deleting irrelevant comments and will continue to do so.
