In the realm of link building, understanding the difference between dofollow and nofollow links is crucial. These two types of links play different roles in SEO and can significantly impact your website's authority and ranking.

Dofollow links are the default type of links that pass on "link juice" or SEO value from one website to another. When a website links to another with a dofollow link, it tells search engines to follow the link and consider it as a vote of confidence for the linked content.

• Pass SEO Value: They transfer authority from the linking site to the linked site.
• Impact on Ranking: They can improve the search engine ranking of the linked site.
• Default Behavior: All links are dofollow by default unless specified otherwise.

In this example, the link to "https://www.example.com" is a dofollow link. Search engines will follow this link and pass SEO value to the linked page.

Nofollow links, on the other hand, do not pass on SEO value. They are used to tell search engines not to follow the link or pass any authority to the linked site. This attribute is often used for links that are paid for or user-generated content to avoid manipulation of search rankings.

• Do Not Pass SEO Value: They do not transfer authority to the linked site.
• No Impact on Ranking: They do not directly affect the search engine ranking of the linked site.
• Specified with Attribute: They are created by adding the rel="nofollow" attribute to the link.

In this example, the link to "https://www.example.com" is a nofollow link. Search engines will not follow this link or pass any SEO value to the linked page.

Let's consider a scenario where you are writing a blog post and want to include both types of links.

• The first link to "https://www.seoexpert.com" is a dofollow link, passing SEO value.
• The second link to "https://www.advertisement.com" is a nofollow link, not passing SEO value due to its sponsored nature.

Identify whether the following links are dofollow or nofollow and explain why.

1. <a href="https://www.example1.com">Example 1</a>
   

2. <a href="https://www.example2.com" rel="nofollow">Example 2</a>
   

3. <a href="https://www.example3.com" rel="noopener noreferrer">Example 3</a>
   

1. Dofollow: The link to "https://www.example1.com" is a dofollow link because it does not have the rel="nofollow" attribute.
2. Nofollow: The link to "https://www.example2.com" is a nofollow link because it includes the rel="nofollow" attribute.
3. Dofollow: The link to "https://www.example3.com" is a dofollow link because rel="noopener noreferrer" does not prevent the link from passing SEO value.

Understanding the difference between dofollow and nofollow links is essential for effective link building. Dofollow links can significantly boost your SEO efforts by passing authority and improving search engine rankings, while nofollow links are useful for managing paid or user-generated content without affecting SEO. By strategically using both types of links, you can enhance your website's authority and maintain a balanced link profile.
