The term Nofollow refers to a value that can be assigned to the rel attribute of an HTML <a> tag. When a link is marked as nofollow, it instructs search engines not to pass any SEO value (link juice) to the linked page. This can be particularly useful for managing the quality of outbound links on a website. This is an alternative to the default behavior of links, which is to pass link equity to the linked page, aka dofollow.
The nofollow attribute was introduced by Google in 2005 to combat spammy practices like comment spam on blogs. By adding nofollow to links in user-generated content, webmasters could prevent spammers from gaining SEO benefits from their spammy links.
To implement nofollow, simply add rel="nofollow" to your anchor tag. Here’s an example:
<a href="https://example.com" rel="nofollow">Example Link</a>
This tells search engines not to follow the link or pass any link equity to the destination URL.
If you are linking to a site as part of a sponsorship or advertising deal, you should use nofollow to comply with Google’s guidelines and avoid penalties.
Links in comments, forums, or any other user-generated content should generally be marked as nofollow to prevent spammy links from affecting your site’s SEO.
If you link to a site but do not fully trust its content or do not want to endorse it, using nofollow is a good practice.
While not mandatory, some webmasters prefer to use nofollow on affiliate links to avoid any potential negative impact on their site’s SEO.
Nofollow links do not pass link equity, so they neither benefit nor harm the SEO of the linked site.nofollow can result in missed opportunities to build relationships and share link equity with other quality sites.Introduced in 2019, rel="ugc" is specifically for links within user-generated content. It serves a similar purpose to nofollow but provides more context to search engines.
Also introduced in 2019, rel="sponsored" is used for links that are part of advertisements, sponsorships, or other compensation agreements.
While nofollow links do not pass link equity, they can still drive traffic and increase brand visibility.
Search engines may still crawl nofollow links and use them for discovery purposes, even if they do not pass link equity.
While nofollow helps manage spam, it is not a complete solution. Webmasters should also use other spam-fighting techniques like moderation and CAPTCHA.
The nofollow attribute is a powerful tool for managing the quality and impact of outbound links on your website. By understanding when and how to use it, you can maintain a healthy link profile and comply with search engine guidelines. Remember, nofollow is just one part of a comprehensive SEO strategy.
