Definition of rel=nofollow
The rel=nofollow attribute is an HTML tag used to instruct search engines not to follow a particular link. This is primarily used to prevent the passing of link equity or PageRank to the linked site, which can be beneficial for controlling SEO and mitigating spam. It was introduced by Google in 2005 as a way to combat comment spam and manage the quality of outbound links.
Practical Use-Cases
The rel=nofollow attribute is commonly used in various scenarios:
- Comment sections: It helps prevent spammy links in blog comments from affecting SEO.
- Paid links: It is used to indicate that a link is sponsored or paid, adhering to Google’s guidelines.
- Untrusted content: When linking to user-generated content or external sites that may not be trustworthy.
Key Aspects
Understanding the implications of using rel=nofollow is crucial:
- SEO Impact: Links with this attribute do not contribute to the link equity of the target page.
- Link Management: It allows webmasters to manage how their site’s authority is distributed.
- Canonical Links: It can be used alongside canonical tags to specify preferred content without passing authority.
Common Pitfalls
