Top 100+ Best Blog Commenting Sites for SEO & Traffic (2025)

Want free traffic and SEO backlinks? Blog commenting is your secret weapon! By leaving thoughtful comments on dofollow sites, you boost rankings while connecting with your niche. Nofollow comments still bring real visitors, it’s a win-win.

Below, we’re sharing 100+ high-quality blog commenting sites that actually work in 2025!

What is Blog Commenting?

Blog commenting is a powerful off-page SEO strategy where you engage with other websites by leaving meaningful comments on their blog posts. Think of it as the digital equivalent of joining a conversation at a networking event – except instead of business cards, you’re strategically placing backlinks that:

1. Boost your site’s search rankings (when using dofollow links)
2. Drive targeted visitors to your content
3. Establish your authority in your niche

Just like leaving breadcrumbs for your audience to follow back to your site, effective blog commenting creates valuable pathways between your content and relevant communities. But remember – today’s Google rewards quality over quantity. A single well-placed comment on a high-authority tech blog (like TechCrunch or Wired) can be more valuable than dozens of spammy links.

Key Benefits of Blog Commenting Sites

🚀 SEO & Ranking Advantages

• ✅ Dofollow Backlinks: High-authority blogs (like TechCrunch, Moz) pass SEO value to your site.

• ✅ Indexing Speed: Links from active blogs help Google discover your content faster.

📈 Traffic & Visibility

• ✅ Targeted Referral Traffic: Readers clicking from niche blogs (e.g., Hacker News) convert better.

• ✅ Brand Exposure: Comments on trending posts put you in front of thousands.

• ✅ Long-Term Traffic: Older threads still rank and drive clicks (e.g., Reddit discussions).

🤝 Community & Networking

• ✅ Audience Insights: Learn what your niche cares about by reading discussions.

Why Blog Commenting Still Matters in 2025

(Beyond Basic Backlinks)

Google’s algorithms keep evolving, but human engagement stays timeless. Here’s why blog commenting deserves your attention:

• ✅ SEO Juice from Dofollow Links: Sites like TechCrunch (DA 94) and Mashable (DA 92) pass link equity. A single contextual link here can outrank 10 low-quality directory submissions.

• ✅ Targeted Traffic from Niche Communities: Comment on a trending AI article? You’ll attract developers, founders, and tech enthusiasts—exactly the audience Techentires wants.

• ✅ Relationship Building: I’ve landed guest posts on Backlinko and Ahrefs purely from thoughtful comments. It’s networking disguised as engagement.

• ✅ Brand Authority: A sharp insight on Hacker News or Reddit’s r/programming positions you as an expert.

The Catch: 95% of comments are ignored because they’re generic, self-promotional, or lazy. We’ll fix that below.

How to Write Comments That Get Clicks (Not Deleted)

(The Tech Commenter’s Framework)

🚫 The FAIL Formula:

“Nice article! My tech blog has tips too: Techentires.com” → Spam bin.

✅ The WIN Formula:

*”Hey Mark, your point about LLM latency issues is spot-on. We benchmarked 15 models at Techentires (results here: [link]). Surprisingly, [Tool X] outperformed GPT-4 in speed tests. Have you tested quantized versions?”*

Advanced Tactics for 2025

(Beyond Basic Comments)

1. Track Dofollow Links with Moz/ahrefs:

   • Filter referring domains by dofollow and DA 50+.

2. Automate Discovery with Google Operators:

• site:reddit.com "best VPN" + "comment"
• "cloud security" + "leave a comment" + 2025

1. Hijack Trending Threads:

   • Use BuzzSumo to find viral tech posts <24 hours old.

2. Turn Replies into Content:

   • Got a great discussion? Expand it into a “Reddit Recap” blog post.

Avoid These While Commenting (Google’s 2025 Spam Policies)

• ❌ Keyword-Stuffed Names: “SEO_Backlink_Expert” → Penalized.

• ❌ Identical Comments: Google devalues duplicate text.

• ❌ Low-Quality Sites: DA <30 blogs can hurt your SEO.

• ❌ Broken Links: Check your linked content works!

Mix dofollow (SEO) and nofollow (traffic) sites. Google wants natural profiles.

Key Points for Smart Blog Commenting

1. Quality > Quantity: 10 thoughtful comments > 100 “nice post!” spams.

2. Tech Niche Focus: Prioritize sites your audience visits (e.g., Hacker News > Mommy blogs).

3. Track Results: Use UTM tags to measure comment-driven traffic in Google Analytics.

4. Be Human: Debate, joke, and share stories. People connect with you, not your link.

“Blog commenting isn’t link-building—it’s community building with SEO benefits.”

FAQs About Blog Commenting Sites (2025)

1. Do blog comments still help SEO in 2025?

Yes, but only if done right. Google prioritizes natural, high-quality engagement. Focus on:

• High-DA sites (DA 50+) like Moz or TechCrunch
• Relevant, value-added comments (no spam)
• Dofollow links (though nofollow can still drive traffic)

2. What’s the difference between dofollow and nofollow blog comments?

• Dofollow: Passes SEO “link juice” to your site (e.g., Backlinko, Ahrefs Blog).
• Nofollow: Doesn’t directly boost rankings but can bring targeted traffic (e.g., Reddit, Medium).
  Pro Tip: A mix of both looks natural to Google.

3. How do I find high-quality blog commenting sites?

Use these free methods:

• Google Operators:
  "tech news" + "leave a comment" + 2025
site:medium.com "AI" + "comments"
• Check Competitors: Use Ahrefs/SEMrush to see where they comment.
• Curated Lists: Like our [55+ Blog Commenting Sites] guide (internal link).

4. How many blog comments should I leave per day?

Quality over quantity!

• 3–5 thoughtful comments/day > 50 generic ones.
• Prioritize replying to replies to build threads.

5. Can blog commenting get my site penalized?

Only if you:

• Spam (e.g., “Nice post! Visit my site”)
• Use fake names like “SEO_Expert2025”
• Comment on spammy, low-DA blogs

6. Which niches work best for blog commenting?

Top niches with active communities:

• Tech (Hacker News, The Verge)
• SEO/Marketing (Moz, Search Engine Journal)
• Business (Entrepreneur, Forbes)

7. How long should my blog comments be?

• Ideal: 50–100 words (enough to add value, not a novel).

• Example:

  *”Great point about Python’s GIL limitation! We tested multiprocessing vs. threading on Techentires (results [here]). For I/O-bound tasks, async reduced latency by 40%. Have you tried PyPy for CPU-heavy workloads?”*

8. Should I use my real name when commenting?

Yes! It builds trust. Avoid:

• Keyword-stuffed names (“Best_Cloud_VPN”)
• Fake personas (“John123”)

9. How do I track if blog comments drive traffic?

• Google Analytics: Check Acquisition > Social > [Reddit/Medium/etc.]
• Bitly Links: Shorten URLs in comments to track clicks.
• UTM Parameters: Tag links (e.g., ?utm_source=blog_comment&utm_medium=referral).

10. What’s the #1 mistake to avoid?

Generic comments. Instead of:

“Helpful article!”
Try:
“Your tip about React’s lazy loading saved us 2s load time! We combined it with Next.js image optimization—full case study [here]. Would this work for SSR apps too?”
