How to do blog commenting in SEO?

Introduction

With the ever-changing dynamics of SEO in 2025, one timeless technique still works wonders—blog commenting. But like every strategy, it only works when done correctly. In this guide, we’ll explore exactly how to do blog commenting in SEO the right way, ensuring you earn quality backlinks, drive referral traffic, and increase your domain authority.

Whether you’re a digital marketer, affiliate blogger, or small business owner, this article will equip you with proven techniques, practical examples, and the best practices to level up your SEO game through smart blog commenting.

What is Blog Commenting in SEO?

Blog commenting involves leaving a response or opinion on a blog post, often with a link back to your own site. This interaction creates an opportunity for exposure, backlinks, and building authority within your niche. While many links are nofollow, they still play a vital role in increasing brand presence and improving SEO through user engagement and relevancy signals.

Why Blog Commenting Still Works in 2025

• Increases Engagement: Builds relationships with bloggers and readers.
• Referral Traffic: Quality comments attract clicks from real users.
• Improves Indexing: Helps new sites get indexed faster via links from crawled domains.
• Builds Authority: Commenting on high-authority blogs boosts your credibility.

Unlike spammy comment strategies of the past, today’s blog commenting is more about relevance, context, and value. Search engines now look at engagement signals and community participation.

Step-by-Step: How to Do Blog Commenting for SEO

Step 1: Identify Relevant Blogs

Use tools like Feedly and BuzzSumo to discover trending content in your niche. You can also use Google operators like:

• "keyword" + "leave a reply"
• "keyword" + "submit a comment"
• "keyword" + inurl:blog

Step 2: Analyze Domain Authority (DA)

Use MozBar or Ahrefs to ensure the blog has a decent DA (20+ preferred). Focus on blogs that are regularly updated and have active readers.

Step 3: Read the Post Thoroughly

Commenting without reading is a red flag. Absorb the key points, tone, and insights of the blog post. Understand the author’s intention before adding your thoughts.

Step 4: Craft a Thoughtful Comment

Your comment should:

• Be 3–5 sentences minimum
• Reference something specific from the article
• Add a new insight or ask a meaningful question
• Include your real name (not keywords)

Example:

“Great post! I especially liked how you outlined the SEO benefits of voice search integration for 2025. I recently tried this on my smart home blog and saw an increase in organic traffic. Do you think schema markup will continue to grow in relevance?”

Step 5: Use Your Real Details

Fill in your real name and use a professional email address. Avoid keyword stuffing in the name field like “SEO Guru.” If allowed, use your homepage or an article URL in the website field.

Best Practices for Blog Commenting

• Be Genuine: Write naturally as you would in a conversation.
• Avoid Overpromotion: Don’t force links; let your insight shine.
• Follow Up: Return to check for replies and continue the conversation.
• Track Your Comments: Maintain a spreadsheet with blog URLs, dates, and responses.

Common Mistakes to Avoid

• Posting “Nice post!” or one-liner comments
• Adding your homepage URL in the comment body
• Ignoring the blog post content
• Commenting only for backlinks

Always comment with the intent to add value, not just to get a link. Build relationships instead of chasing rankings.
