Blog commenting is probably the oldest link building strategy in SEO. It has been around since the early 2000s, and most people have either forgotten about it or dismiss it as spam. But here is the thing: blog commenting still works when you do it correctly. I have built dozens of quality backlinks through thoughtful comments on relevant blogs, and those links still drive referral traffic to my sites years later.
The key word is "thoughtfully." Leaving a comment that says "Great post, check out my blog" on every blog you find is spam. That will get you nowhere. But leaving a genuine, insightful comment that adds value to the conversation? That builds relationships, earns backlinks, and sends targeted traffic to your site.
I am going to share exactly how I approach blog commenting as a link building strategy. This is not about automating anything or gaming the system. It is about being a genuine participant in your niche community while naturally earning links back to your content.
Why Blog Comments Still Work in 2026
A lot has changed in SEO over the years. Google got smarter about detecting manipulative link building. Most comment sections added nofollow attributes to links. Spam filters got stricter. All of this made blog commenting less effective as a pure link building tactic. But it did not make it useless.
Here is what blog commenting actually does for you when you do it right. First, it puts your name and your website in front of an audience that is already interested in your niche. When you leave a valuable comment on a popular SEO blog, other readers see it. Some of them click through to your site. That is targeted referral traffic you would not get otherwise.
Second, it builds relationships with other bloggers and website owners in your niche. I have gotten guest post opportunities, collaboration invites, and even joint venture partnerships from relationships that started with a blog comment. These relationships lead to much more valuable links than the comment link itself.
Third, while most blog comments are nofollow, Google has said that nofollow links can still influence rankings in certain contexts. John Mueller from Google has confirmed that Google uses nofollow links as hints. They do not pass PageRank the way dofollow links do, but they help Google discover your pages and understand your site's relevance in the niche.
Fourth, some blogs still offer dofollow comment links. These are becoming rarer, but they exist. Finding and contributing to these blogs can provide direct SEO value along with all the other benefits.
How to Find the Right Blogs for Commenting
Not all blogs are worth your time. I am selective about where I leave comments because a thoughtful comment takes five to ten minutes to write. If I am going to invest that time, I want to make sure it goes somewhere that will actually benefit me.
I look for blogs that meet four criteria. The blog should be active, meaning the owner publishes regularly and responds to comments. An abandoned blog with the last post from 2023 is not worth your time. The blog should have real readers, which you can tell from the number and quality of comments on recent posts. The blog should be topically relevant to your niche. A comment on a fitness blog does not help your SEO blog. And the blog should allow comments with a website field or author bio link.
To find these blogs, I start with Google searches using operators like "write a comment" or "leave a comment" combined with my niche keywords. For example, "SEO tips write a comment" or "blogging tips leave a comment." This filters for blogs that have open comment sections.
I also look at the blogs that already link to my competitors using tools like free SEO tools for bloggers. If a blog links to a competitor, the owner is clearly willing to reference external resources. A thoughtful comment on that blog might eventually lead to a link to your content as well.
How to Write Comments That Get Approved and Noticed
This is where most people fail at blog commenting. They treat it as a checkbox exercise. They read the title, skim the first paragraph, and write something generic like "Thanks for sharing this informative post." Blog owners delete these comments. I know because I delete them on my own blogs, and I have talked to dozens of other bloggers who do the same.
A comment that gets approved and generates results looks nothing like spam. Here is my process for writing comments that actually work.
Read the Entire Post First
This sounds obvious, but you would be surprised how many people skip it. I read the full post before writing a single word of my comment. I want to understand the main argument, the specific examples, and the conclusions. This lets me write a comment that engages with the actual content, not just the general topic.
When I read a post about reducing bounce rate, I look for specific techniques the author mentions. Maybe they talked about improving page speed but did not mention internal linking. That gives me a natural opening to add value in my comment by bringing up the internal linking angle.
Add a Specific Insight or Experience
The best comments share something the original post did not cover. I share a personal experience, a relevant case study, or a different perspective on the topic. This makes the comment genuinely valuable to other readers, not just a pat on the back for the author.
For example, if the post discusses five ways to find low competition keywords, I might comment about a sixth method I have used successfully. I explain the approach briefly and share a specific result I got. This kind of comment positions me as someone with real expertise, not just someone fishing for backlinks.
Keep It Concise But Substantial
The ideal comment is three to six sentences long. Short enough that the blog owner will actually read it, but long enough to demonstrate genuine engagement. One-liner comments look like spam. Three-paragraph essays look desperate. Find the middle ground.
Use Your Real Name and Website
Use your actual name, not a keyword. If your name is Wasim, do not enter "SEO Tips by Wasim" as your display name. Blog owners spot this immediately and it screams spam. Use your real name and your actual website URL. Let the quality of your comment speak for itself.
Common Mistakes That Kill Your Comment Strategy
I have made most of these mistakes myself when I was starting out. Learn from my errors so you do not waste time repeating them.
Commenting too fast. If you leave ten comments in twenty minutes, you are not reading the posts. Blog owners can tell when someone is blasting comments across their site without engaging. I limit myself to two or three thoughtful comments per session and spread them across different days.
Dropping links in the comment body. Most comment systems will mark comments with URLs in the body as spam. Include your link in the website field where it belongs. If the comment platform allows HTML links, use them sparingly and only when genuinely relevant. I almost never put links in comment bodies.
Self-promoting instead of engaging. Every sentence in your comment should add value to the conversation, not promote your own content. If more than ten percent of your comment is about you or your website, rewrite it. The goal is to be helpful first. The backlink is a secondary benefit.
Targeting irrelevant blogs. Commenting on a travel blog when you run a tech website does not help anyone. The blog owner will delete your comment because it is off-topic. Readers will not click through because they are not your target audience. Stay within your niche.
Giving up after a few attempts. Building backlinks through blog commenting is a long game. I might leave fifty comments before I see meaningful results. The relationship you build with one blog owner can lead to opportunities worth far more than any single comment link.
How I Track Comment Links and Measure Results
I keep a simple spreadsheet for my blog commenting activity. It has columns for the blog URL, the post URL, the date I commented, whether the comment was approved, whether the link is dofollow or nofollow, and any referral traffic I have received. I check this spreadsheet monthly to see which blogs are sending the most value.
I also monitor referral traffic in Google Search Console and Google Analytics. Good blog comments send consistent referral traffic over time. If a blog sends me five or more visitors per month from a single comment, that comment was worth the five minutes it took to write it.
For SEO impact, I track the pages that receive comment links in my rank tracking tool. While I do not expect dramatic ranking changes from nofollow comment links alone, I have seen pages gain a rankings boost when blog commenting is combined with other strategies like the skyscraper technique and internal linking optimization.
The Real Value of Blog Commenting Beyond Links
If I am being completely honest, the backlinks I get from blog comments are a nice bonus, but they are not the primary reason I do it. The real value is in the relationships I build with other bloggers and the exposure I get in front of relevant audiences.
Some of my most valuable professional connections started with a blog comment. A comment I left on a popular web development blog led to a guest posting opportunity that sent me thousands of visitors. A thoughtful response to another blogger's question about blog monetization led to a collaboration that generated revenue for both of us.
Think of blog commenting as networking, not link building. When you approach it with the mindset of adding value and building genuine connections, the links and traffic follow naturally. When you approach it with the mindset of extracting links, you will be disappointed every time.
Set aside thirty minutes a day, three days a week, for blog commenting. Find two or three relevant posts, read them carefully, and write thoughtful comments. Do this consistently for three months, and you will see the results. Not overnight, but steadily and sustainably.
