Blog Commenting for SEO
Blog commenting for SEO is leaving relevant, helpful comments on other sites' blog posts to earn visibility, referral traffic, and occasional links, rather than strong direct ranking value.
- Also called
- comment marketing
- Applies to
- link building, brand exposure, outreach
- Where it matters most
- niche blogs with active communities
Key points
- Most blog comment links are nofollow and do not pass direct ranking signals.
- The main value is indirect: referral traffic, brand visibility, and relationship building.
- Effective comments add genuine value by sharing experience, insight, or a different perspective.
- Generic comments such as 'Great post!' are low-value and often ignored or viewed as spammy.
- Commenting works better when done consistently over time rather than as a one-off link grab.
How it works
Blog commenting for SEO involves leaving a comment on a blog post in your niche, typically including your name, website URL, and the comment text. Most blog platforms automatically add a nofollow attribute to links in comments, meaning they usually do not count as direct ranking signals for Google.
The process starts with finding relevant blogs that accept comments and have active discussions. Search operators and monitoring tools can help locate recent posts with engaged communities. Once you find a suitable post, read it thoroughly and write a comment that adds value — for example, sharing a relevant experience, offering data, or presenting a different perspective.
Using your real name is recommended for transparency and professionalism. The comment should be contextual and avoid dropping a link without relevance or trying to force keyword-rich self-promotion. Generic praise or filler text that adds no new information is a known mistake and is often ignored or treated as spam.
Why it matters
For SEO practitioners, blog commenting is best treated as a low-cost relationship and discovery tactic, not a primary ranking strategy. The main value is often indirect: referral traffic, brand visibility, and relationship building with site owners and readers. These connections can later lead to stronger backlinks through outreach or collaboration.
Commenting works better when done consistently over time rather than as a one-off link grab. It is often used as part of a broader strategy alongside tactics such as guest posting or digital PR. Relevance matters: comment on blogs that are closely related to your niche or target topic to maximise the chance of being seen by the right audience.
This tactic changes mainly because Google's handling of user-generated content, nofollow/sponsored/ugc attributes, and spam detection can evolve over time. Advice that focuses on volume, exact-match anchor text, or link placement in comments is especially risky, because comment links are commonly nofollow and may provide little or no direct ranking value.
