Nofollow links are a type of hyperlink attribute used in HTML to instruct search engines not to follow or crawl a particular link. These links are commonly used to control the flow of link juice, which is the SEO value or ranking power passed from one webpage to another through hyperlinks. Nofollow links were introduced to combat spammy and manipulative SEO practices and help search engines better understand the quality and intent of links on a webpage.

Here’s a Detailed Explanation of Nofollow Links:
Nofollow links are implemented using the “nofollow” HTML attribute within the anchor (a) tag. When added to a hyperlink, this attribute tells search engine crawlers not to follow the link or take it into account when calculating search engine rankings.
Example: <a href=”https://example.com” rel=”nofollow”>Visit Example.com</a>
- Combat Spam: Nofollow links were originally introduced by search engines like Google to combat link spam, where websites were artificially inflating their search rankings by creating numerous low-quality or irrelevant backlinks.
- User-generated Content: Websites often use nofollow link for user-generated content, such as comments and forum posts, to prevent any potentially harmful or spammy links from impacting their own SEO.
- No Link Juice Transfer: Search engines like Google do not pass PageRank through nofollow links. This means that the linked webpage doesn’t receive any SEO benefit from the linking page.
- Indexing: While nofollow links won’t directly affect search engine rankings, they can still be indexed by search engines, potentially leading to traffic or exposure.
How to Add Nofollow Links:
- To create a nofollow link, add the
rel="nofollow"attribute to the anchor tag.
- For example, in WordPress, you can check a box or use plugins to automatically add nofollow attributes to links within comments or specific URLs.
When to Use Nofollow Links:
- Untrusted Sources: Links from untrusted or user-generated content should be nofollowed to prevent potential spam from impacting your site’s SEO.
- Paid Links: Any paid links or sponsored content should have nofollow attributes to comply with search engine guidelines.
- User-generated Content: When allowing users to post content with links on your website, it’s a good practice to add nofollow attributes to those links.
- Advertisements: Links within advertisements, especially if they are paid placements, should be nofollowed.

Difference Between DoFollow or Nofollow Links
Dofollow and nofollow are two types of HTML link attributes used in web development to control how search engines and web crawlers treat hyperlinks on a webpage. These attributes can impact a website’s search engine optimization (SEO) and can affect how search engines index and rank the linked content. Here are the main differences between dofollow and nofollow link:
- Default Behavior: When you create a hyperlink in HTML without specifying the “nofollow” attribute, it is considered a dofollow link by default.
- Search Engine Crawling: Search engines follow dofollow links and consider them as votes of confidence for the linked content. This means they may crawl and index the linked pages.
- SEO Impact: Dofollow links are valuable for SEO because they can pass link equity (also known as PageRank) from one page to another. This can help improve the search engine ranking of the linked page.
- User Experience: Dofollow links are typically used for editorial links, endorsements, and recommendations. They are meant to provide value to users by directing them to relevant and trustworthy content.
