When you think of search engine optimization (SEO), you might picture on-page keyword strategies, carefully crafted meta descriptions, and robust link-building campaigns. Blog commenting, on the other hand, might feel old-school or too subtle to influence your SEO results. But when done correctly, blog commenting can still be a valuable part of your overall strategy. By thoughtfully contributing to discussions on relevant sites, you can build relationships, earn respect, and even enjoy some indirect SEO benefits. On the flip side, approaching blog commenting carelessly—spamming your URL in every comment section you can find—will likely harm your reputation and possibly earn you penalties from search engines.
In this guide, we’ll walk through the do’s and don’ts of blog commenting for SEO. We’ll explain how adding meaningful comments can strengthen your online presence, highlight what behaviors to avoid, and provide a roadmap for making the most of your efforts. Let’s dive in and explore how to use blog commenting as a strategic tool to boost your digital authority without running afoul of Google’s guidelines.
It’s fair to ask: “Does blog commenting really matter for SEO?” The short answer is yes—but not always in the direct, link-building way people once believed. In the early days of SEO, dropping a link to your site in a blog’s comment section seemed like a quick hack to score a backlink. However, Google and other search engines caught on. Today, most blog comment links are marked “nofollow,” which signals to search engines that they shouldn’t pass direct link equity.
Still, blog commenting can matter in other, less direct ways. By offering thoughtful, relevant comments on industry blogs, you can:
In other words, while blog commenting won’t hand you easy SEO wins on a silver platter, it can support your broader content marketing and authority-building strategy. Think of it as a way to show you’re an engaged community member, not just another site scrambling for quick SEO gains.
Google has emphasized the importance of E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness) as a way to gauge the quality and credibility of content creators. While blog comments themselves might not be a direct ranking factor, your activity around them can still signal to both users and search engines that you’re knowledgeable, reliable, and invested in the community.
Here’s how blog commenting ties into E-E-A-T:
Remember, E-E-A-T isn’t only about what’s on your own website. It’s about your presence and reputation online. High-quality blog commenting gives you yet another channel to reinforce that you’re a trustworthy source worth following.
Approach blog commenting as an extension of your brand’s voice and values. Here are some best practices to keep in mind.
The quickest way to lose credibility is by commenting on something you haven’t fully read. Take the time to read the entire blog post, understand the author’s perspective, and consider what the community might gain from your input. This ensures your comment is actually relevant and helps foster a meaningful discussion.
Your comment should go beyond a simple “Great post!” Offer a unique angle, a piece of data, or a personal anecdote that adds depth to the conversation. Readers (and the blog’s author) will appreciate comments that contribute genuinely helpful or insightful information rather than just flattering the writer.
Maintain a tone that’s polite and thoughtful, even if you disagree with the author or another commenter. Keep it constructive. Instead of attacking someone’s viewpoint, focus on explaining why you see things differently. Respectful interactions are more likely to foster goodwill, build positive relationships, and encourage further dialogue.
Hiding behind a fake persona can make you seem untrustworthy. Use your real name or your brand name—something that allows others to recognize and remember you. This transparency helps build trust and may encourage others to visit your site. Your brand should be consistent across platforms and comment sections, so people come to know you as a legitimate presence in the community.
Commenting on random blogs just to leave your link is a waste of time and can look spammy. Instead, target blogs that cover topics relevant to your industry, niche, or expertise. Not only will you find readers who actually care about what you have to say, but you’ll also be contributing to discussions that can position you as a knowledgeable figure in that field.
Nobody wants to read a four-paragraph rant. Keep your comment concise, but not so short that it adds no value. A few well-structured sentences that directly address a point in the article are often enough. If you reference external resources, do so thoughtfully. Make it easy for readers to follow along by keeping your comment clean and readable.
One of the often-overlooked benefits of blog commenting is networking. By consistently appearing in the comments section of a particular blog, you can build a rapport with the blog owner or editor. This can lead to further opportunities like guest posting, interviews, or collaborative projects. Think of comments as virtual handshakes that can lead to stronger professional relationships down the line.
Just as there are best practices, there are also pitfalls to avoid. Falling into these traps can damage your reputation and may even hurt your SEO efforts in the long run.
A surefire way to earn a spammy reputation is to drop irrelevant or overly promotional links in your comments. If linking to your content doesn’t add genuine value to the discussion, don’t do it. Google and webmasters are quick to penalize or remove comments that are clearly self-serving without any real contribution.
If you do include a link, avoid stuffing it with an exact-match keyword anchor text. “Best SEO services in Los Angeles” as your comment name or anchor text looks forced and manipulative. It’s best to use your actual name or your brand name naturally. If the platform allows you to link your website within the provided fields, keep it straightforward and honest, not keyword-stuffed.
If all you do is copy and paste a “Great article, keep it up!” comment on every blog, you’re not going to gain any respect. Readers can smell insincerity a mile away. And if the blog owner thinks you’re a bot or a spammer, your comments will likely never see the light of day. Put in the effort to craft a unique comment for each post.
Many blogs have explicit commenting rules, such as no promotional links, no abusive language, or no off-topic discussions. Respect these rules. Violating them not only risks having your comment removed, but it can also damage your reputation with the site’s audience. If you’re unsure whether something is allowed, err on the side of caution.
Yes, you’re looking for ways to boost visibility and authority, but if SEO is the only reason you’re commenting, you’ll likely come across as insincere. Community members—and Google—are savvy enough to spot someone who’s just trying to manipulate the system. Focus on fostering real conversations, and the SEO benefits may follow naturally.
Choosing where to comment can be as critical as what you say. Start by looking for reputable blogs in your niche. They should have an active readership and post high-quality content. Consider using tools like industry forums, LinkedIn groups, and content discovery platforms to find blogs that align with your brand. Focus on sites that:
While blog commenting isn’t always easy to measure, you can keep an eye on a few metrics:
Keep track of the blogs you comment on, the nature of your comments, and any notable outcomes (like an uptick in referral traffic or a new business lead). Over time, you’ll get a feel for which blogs are worth your effort.
Misconception #1: Blog commenting is dead.
While it’s no longer a straightforward link-building trick, blog commenting is far from useless. Its role has evolved into more of a community-building and brand authority exercise.
Misconception #2: Any comment is good exposure.
Quality trumps quantity. A few thoughtful, value-driven comments on authoritative blogs can have more impact than dozens of generic comments sprinkled across random sites.
Misconception #3: Blog comments directly boost your PageRank.
Most comment links are nofollow, so they don’t directly improve your search rankings. Instead, they can indirectly help by raising brand awareness, driving referral traffic, and fostering trust.
Blog commenting should be one tool in your SEO toolbox, not the entire kit. Don’t rely solely on comments for building your online presence. Instead, integrate blog commenting with other SEO strategies:
When all these efforts align, your brand gains authority, trust, and visibility, making blog commenting a part of a larger, well-rounded approach.
As the digital landscape evolves, the role of blog commenting may continue to shift. However, the core principles—authenticity, value, and community engagement—will remain relevant. Whether people interact in blog comment sections, forums, Q&A platforms, or social media threads, the key is to contribute meaningfully to conversations that matter to your audience and your industry.
To ensure longevity, keep these tips in mind:
Good Comment Example:
“Great article! I particularly appreciate how you broke down the steps for applying schema markup. I’ve tried this on a few client sites, and while it took some effort to set up, the improved search snippet display really helped their CTR. Have you tested different schema types to see if certain ones perform better in specific industries?”
Why it’s good: It references specific parts of the post, offers an anecdote from personal experience, and asks a thoughtful question.
Bad Comment Example:
“Nice blog! Visit my site www.example.com for the best SEO tips!”
Why it’s bad: It provides no actual value or insight, just a self-promotional link.
Not all conversations are pleasant. Sometimes, you might face criticism or negativity when commenting on a blog. The key is how you handle it:
Handling negativity gracefully can actually enhance your reputation. It shows you can remain professional under pressure, strengthening the trust others place in you.
Blog commenting may not have the direct SEO power it once did, but it remains a valuable way to engage with your industry, foster relationships, and show off your expertise. By following the do’s—providing valuable insights, being respectful, and focusing on relevant, high-quality blogs—and avoiding the don’ts—spamming links, leaving generic comments, or ignoring community guidelines—you can harness blog commenting as a subtle yet effective part of your online marketing strategy.
Think of blog commenting not as a shortcut to better rankings, but as a long-term investment in your brand’s reputation. When you approach it with authenticity, helpfulness, and a genuine interest in the conversation, you’ll likely see positive results. Whether it’s increased referral traffic, stronger professional connections, or a well-earned boost in industry authority, the time you invest in meaningful blog commenting can pay off in ways that matter—both to your readers and to your SEO efforts.
