Comment Backlinks: Their Role in Site Ranking and Sites that Allow Them


Backlinks are an essential component of search engine optimization (SEO), playing a crucial role in determining a website’s ranking on search engine results pages (SERPs). Comment backlinks, specifically, are links that are placed within the comments section of a blog or website. While they can be a valuable SEO tool when used correctly, it’s important to understand which sites allow comment backlinks and how they contribute to site ranking.

How Comment Backlinks Work

Comment backlinks are created when a user leaves a comment on a blog post or article and includes a link to their own website or a relevant page. These links are usually clickable and direct users to the commenter’s site when clicked. From an SEO perspective, comment backlinks serve as a signal to search engines that other websites find the content valuable enough to link to.

Sites that Allow Comment Backlinks

Several types of websites and platforms allow comment backlinks. Here are some common examples:

  1. Blogs: Many blogs allow readers to leave comments on their posts. When commenting, users often have the option to include their website URL. Blogs in various niches, from fashion to technology to finance, offer opportunities for comment backlinks.
  2. Forums: Online forums and discussion boards are another platform where comment backlinks are prevalent. Users engage in discussions and can include links to relevant content within their comments.
  3. News Websites: Some news websites allow users to comment on articles. While these comments are usually moderated, they can include backlinks to related resources or further information.
  4. Social Media: Social media platforms like Facebook and LinkedIn often allow users to leave comments on posts. These comments can sometimes include links to external websites.
  5. Q&A Websites: Platforms like Quora and Reddit allow users to ask and answer questions. Commenters can include links to relevant resources or articles that provide more information.

The Role of Comment Backlinks in Site Ranking

Comment backlinks can influence a website’s ranking in several ways:

  1. Increased Website Traffic: When users click on a comment backlink, they are directed to the linked website. This can lead to increased traffic, which is a positive signal to search engines.
  2. Improved Crawling and Indexing: Search engine crawlers follow backlinks to discover new content. Comment backlinks provide an additional path for crawlers to find and index a website’s pages.
  3. Enhanced Authority and Relevance: Backlinks from reputable and relevant websites are seen as a vote of confidence. Comment backlinks from authoritative sources can help establish a website’s authority and relevance in its niche.
  4. Diversification of Backlink Profile: A diverse backlink profile, including comment backlinks, signals to search engines that a website is not relying solely on one type of link building. This can contribute to a more natural and organic link profile.
  5. Engagement and Social Signals: Comments on blog posts and articles can indicate engagement and interest in the content. Search engines may consider this engagement, along with comment backlinks, when determining a site’s relevance and value to users.

Best Practices for Using Comment Backlinks

While comment backlinks can be beneficial for SEO, it’s important to approach them strategically to avoid potential pitfalls. Here are some best practices:

  1. Relevance: Ensure that the comment and the linked content are relevant to the discussion and the blog post/article. Irrelevant comments or links may be seen as spam.
  2. Quality Comments: Write thoughtful, engaging comments that add value to the conversation. Generic or spammy comments are likely to be ignored or deleted.
  3. Avoid Keyword Stuffing: When including a link, avoid stuffing keywords into the anchor text. Use natural language that accurately describes the linked content.
  4. Moderation and Engagement: Engage with the blog or forum community by responding to comments and participating in discussions. This builds credibility and may lead to more opportunities for backlinks.
  5. Dofollow vs. Nofollow Links: Be aware of whether the site uses dofollow or nofollow links for comments. Dofollow links pass link equity, while nofollow links do not. Both can be beneficial, but dofollow links have a more direct impact on SEO.

Sites that Allow Comment Backlinks: Examples

Let’s explore some popular websites and platforms where comment backlinks are allowed:

  1. WordPress Blogs: Many WordPress blogs allow users to leave comments with their website URLs. Look for blogs in your niche and engage with their content.
  2. Medium: Medium is a platform for sharing articles and stories. Users can leave comments on posts, often including their own website links.
  3. Quora: Quora is a question-and-answer platform where users can provide answers to queries. Including relevant links in your answers can lead to comment backlinks.
  4. TechCrunch: A popular tech news website, TechCrunch allows users to comment on articles. Engaging with discussions can lead to comment backlinks.
  5. Reddit: While Reddit’s links are typically nofollowed, engaging in discussions and providing valuable insights can still drive traffic and visibility to your website.
  6. LinkedIn: Comments on LinkedIn posts can include links to relevant articles or resources. Engaging with professional discussions can lead to comment backlinks.
  7. YouTube: Comments on YouTube videos often allow users to include their website URLs. Engaging with video content creators can lead to backlinks.


Comment backlinks can be a valuable part of an SEO strategy when used effectively. They provide opportunities for increased traffic, improved crawling and indexing, and enhanced authority and relevance. However, it’s crucial to approach comment backlinking with care, focusing on relevance, quality comments, and engagement with the community. By understanding which sites allow comment backlinks and following best practices, website owners and bloggers can leverage this strategy to boost their site’s ranking and visibility in search engine results.
