If you’re building a strong backlink profile for your website, Blog comments for off-page SEO are a smart, white-hat method to add into your strategy. Blog commenting is one of the oldest SEO techniques — and when done manually on relevant, high-DA websites, it remains highly effective. This technique helps with link diversity, faster indexing, and long-term authority building.



Many overlook blog commenting because it’s often associated with spam. However, manual and niche-relevant blog comments can actually improve your website’s trust and organic visibility without triggering penalties from search engines.



What Are Blog Comments in SEO?

Blog comments are short, user-submitted texts placed in the comment section of blog posts. When you leave a thoughtful, relevant comment and include your name or website, it can often include a link back to your site. While these links are usually “nofollow,” they still contribute to a natural-looking link profile — which is essential for long-term ranking success.



Even Google has confirmed that not all nofollow links are ignored. They can still serve as important discovery paths and indirect ranking signals.



Why Blog Commenting Still Matters

Here are a few reasons why blog comments still play a role in modern SEO:



Boosts Link Diversity

A healthy backlink profile includes a mix of link types — dofollow, nofollow, contextual, profile, and yes, blog comments.



Improves Indexing Speed

Comments on blogs with frequent crawlers help search engines find your new content faster.



Increases Niche Visibility

By engaging with blog content in your niche, you also gain exposure with a relevant audience.



Safe and White-Hat

As long as comments are manual and relevant, they’re safe from algorithm penalties and spam filters.



Cost-Effective SEO Boost

Compared to guest posts or outreach campaigns, blog comments are far more affordable — and scalable.



How to Do Blog Commenting Right

Be Relevant: Comment only on blogs that are topically related to your website.



Add Value: Avoid generic phrases like “Nice post!” Instead, contribute meaningfully to the discussion.



Use a Real Name or Brand: Avoid keyword stuffing in the name field.



Stay Consistent: A few quality comments every week can build authority over time.



Avoid Automation: Always use manual methods to stay safe and effective.



Ideal Use Cases

This strategy is ideal for:



SEO professionals managing link campaigns



Affiliate websites looking for low-cost visibility



Bloggers building community and engagement



Business websites trying to build trust



New domains needing fast, indexed links



It’s especially useful in the early stages of SEO when domain authority is still low, and trust signals need to be built naturally.
