What is a Nofollow Link?

In the realm of Search Engine Optimization (SEO) and website development, the term nofollow link occupies a significant place. A nofollow link is essentially a hyperlink that comes with a specific attribute telling search engines to ignore the link in terms of passing on what is often termed as "link juice" or SEO benefits. This attribute can significantly influence the way web content is discovered, indexed, and valued by search engines.

The concept of a nofollow link was introduced in 2005 by Google, in collaboration with Microsoft and Yahoo, as a method to combat spam and the manipulation of search engine rankings. Since its inception, it has become a fundamental part of SEO strategies and website management.

To create a nofollow link, the attribute rel="nofollow" is added to the anchor tag in the HTML code of the webpage. This effectively informs search engines not to follow the link or consider it when evaluating the website's position or authority in search engine results pages (SERPs).

Example of a Nofollow Link in HTML:

<a href="[http](/glossary/http)://www.example.com" rel="nofollow">Example Website</a>

There are several reasons why webmasters and SEO professionals use nofollow links:

• To Discourage Spam: In blog comments, forums, and user-generated content to prevent spammy links from affecting the website's SEO.
• Paid Links: When websites are paid to include a link, adding the nofollow attribute ensures that they are not passing link equity in exchange for compensation.
• Untrusted Content: When linking to websites or content that cannot be vouched for, to avoid potentially harmful SEO impact.

In September 2019, Google announced an update to its policy regarding nofollow links, introducing two new rel attributes - rel="sponsored" for paid or sponsored links, and rel="ugc" for user-generated content. This update expanded the utility of these tags, offering webmasters and SEO specialists more precise ways to describe the nature of links.

However, while the nofollow link has been a staple in controlling and directing search engine behavior, it's important to note that Google treats it as a "hint" rather than a directive. This means that while nofollow links do not directly influence a page's rank, Google may choose to crawl them if it deems necessary.

In conclusion, the nofollow link is an essential tool in the SEO toolkit. It helps maintain the integrity of search results and allows webmasters to manage the impact of external links on their websites. With the evolving nature of search engines and their algorithms, understanding how and when to use nofollow links remains crucial for anyone involved in digital marketing or website management.
