What is Blog Commenting in SEO?
Blog Commenting in SEO refers to the practice of leaving comments on blog posts—often with a link back to your own website—to build backlinks, improve brand visibility, drive referral traffic, and engage with relevant audiences.
While once heavily used for link-building, blog commenting has evolved to be more about genuine interaction, thought leadership, and community participation when done correctly.
Key Objectives of Blog Commenting
| Objective | Description |
|---|---|
| Backlink Acquisition | Adding your website link in the comment form (usually in the name or URL field) to gain backlinks. |
| Community Engagement | Building relationships with blog authors, influencers, and niche communities through thoughtful contributions. |
| Referral Traffic | Attracting interested users to visit your site through engaging, helpful comments that include a relevant link. |
| Authority Building | Demonstrating expertise by sharing knowledge or alternative perspectives in the comments section. |
Example of Blog Commenting
“10 Tips for Improving Website Speed”
“Great article! I found the tip about optimizing images particularly helpful. On my blog, I recently added lazy loading and saw significant improvements in load time. I’ve written a full guide on how to implement it step-by-step: [yourwebsite.com/lazy-loading-guide]. Thanks for sharing these insights!”
Why it works:
- It’s relevant.
- It adds value to the discussion.
- The link is contextually appropriate and helpful.
Types of Blog Commenting
1. Genuine Engagement (White-Hat SEO)
Adds value to the conversation.
Respects the topic and audience.
Encourages dialogue or shares a useful resource.
Builds long-term relationships and trust.
2. Spammy Commenting (Black-Hat SEO)
Generic, copy-pasted comments like “Nice post!” or “Thanks for sharing.”
Includes irrelevant or promotional links.
May be flagged or removed by moderators.
Can lead to Google penalties or devaluation of links.
Example of Spammy Comment:
“Great info! Visit my website for free SEO tools: [spammylink.com]”
SEO Value of Blog Commenting
| SEO Benefit | Explanation |
|---|---|
| Backlink Profile Improvement | Most comment links are nofollow, but they still add diversity to your backlink profile. |
| Brand Visibility | Appearing consistently on authoritative blogs boosts recognition. |
| Referral Traffic Boost | Insightful comments often attract clicks from curious readers. |
| Topical Relevance | Helps associate your name and website with a specific niche or topic. |
Limitations & Considerations
Most blog comment links are “nofollow”, meaning they don’t pass SEO “link juice.”
Excessive or irrelevant commenting can result in spam flags or domain reputation issues.
Avoid commenting just for the link—focus on value.
Use your real name or brand, not keywords like “Best SEO Services.”
Final Thoughts
Blog Commenting is still a valuable tactic in modern SEO when used correctly. It’s not about chasing backlinks—it’s about engagement, authority, and adding value to the conversation.
Comment like a human, not a bot, and your efforts will be rewarded with visibility, referrals, and community trust—even if the backlinks are nofollow.
