What Is a Nofollow Link? (And Why It Matters)
In the complex world of Search Engine Optimization (SEO), mastering the art of linking is crucial. Amongst various types of links, you may have heard of "nofollow links." But what exactly are nofollow links, and why do they matter? This comprehensive guide aims to dissect the intricacies of nofollow links, their impact on SEO, and the best practices around their use.
Understanding Nofollow Links
What Are Nofollow Links?
A nofollow link is a hyperlink that includes a specific HTML attribute (rel="nofollow"
) which tells search engine crawlers not to follow the link to its destination page. As a result, the linked page does not receive any "link juice" or authority from the original page.
The Development of Nofollow Links
The concept of nofollow links was introduced by Google in 2005. The primary purpose was to combat spam, particularly in blog comments, which were often exploited by spammers to build links to their sites.
How to Identify Nofollow Links
To verify if a link is a nofollow, simply inspect the HTML of the link. It should look like this:
html
<a href="https://example.com" rel="nofollow">Example Link</a>
Why Nofollow Links Matter
Impact on SEO
-
Link Juice and PageRank: Nofollow links do not pass along link juice. This means they typically don't directly impact the PageRank of the linked site.
-
Diversity and Natural Link Profile: A healthy backlink profile includes a mixture of dofollow and nofollow links. This diversity appears more natural to search engines and aids in avoiding penalties.
Use Cases for Nofollow Links
1. Sponsored Content
Links that are part of paid advertising or sponsorship should always be nofollow. This complies with Google's guidelines by preventing the artificial inflation of PageRank.
2. User-Generated Content
Platforms with user-generated content (like forums or blog comments) should use nofollow links to minimize spam-related issues.
3. Untrusted Content
When linking to pages with content that you can't vouch for, using nofollow ensures you aren't inadvertently boosting disreputable sites.
Best Practices for Nofollow Links
Correct Implementation
- Always use the nofollow attribute when linking to paid content.
- Apply nofollow links to areas prone to spam (comments sections, forums).
Monitor Your Link Profile
- Keep a balanced ratio of nofollow to dofollow links in your link profile.
- Utilize tools like Google Search Console to analyze and manage your site's link data.
Evolving Use of Nofollow
In September 2019, Google announced changes to how nofollow links are handled. Nofollow became a "hint" rather than a strict directive, giving Google the discretion to use the links for crawling and indexing purposes if deemed relevant.
Conclusion
While nofollow links may not hold the same PageRank influence as dofollow links, they are an essential tool in your SEO arsenal. By strategically using nofollow attributes, you can protect your site from spam, maintain a diverse link profile, and adhere to search engine guidelines. In the dynamic realm of SEO, understanding and utilizing nofollow links effectively plays a crucial role in sustainable, ethical online visibility.
