DoFollow vs. Nofollow: A Complete Guide to Mastering Your Link Profile

Introduction: Not All Links Are Created Equal

In the vast ecosystem of the internet, links are the essential pathways that connect everything. For search engines like Google, they are more than just connections; they are votes of confidence. When one website links to another, it's essentially vouching for that site's content. This "vote" is what we call "link juice" or SEO authority, and it is a cornerstone of how search engines rank websites.

However, webmasters have the power to control how these votes are cast using special HTML attributes. The two most important of these are dofollow and nofollow. Understanding the difference between them is absolutely critical for anyone serious about SEO, link building, or website management.

Manually checking every link can be a daunting task, but with a DoFollow/NoFollow Checker, you can instantly analyze any webpage and see exactly how it instructs search engines to treat its links.

The Core Concepts: What Are DoFollow and Nofollow Links?

What is a DoFollow Link?

A "dofollow" link is the standard, default type of hyperlink. When a webpage links to another without any special instructions, the link is considered "dofollow".

• Function: Instructs search engine crawlers to follow the link and pass authority (link juice) from the source page to the destination page.
• SEO Impact: Receiving dofollow links from high-quality, relevant websites is one of the most powerful ways to improve your search engine rankings.

HTML Example:

(The absence of a rel attribute makes it dofollow by default.)

What is a Nofollow Link?

A "nofollow" link contains a special attribute, rel="nofollow", in its HTML code. This attribute provides a specific instruction to search engine bots.

• Function: Tells search engines not to follow the link or pass any link authority.
• SEO Impact: Does not directly influence rankings, but still contributes to traffic and link diversity.

HTML Example:

The Evolution: rel="sponsored" and rel="ugc"

In 2019, Google introduced two new link attributes:

• rel="sponsored": For paid or sponsored links, including ads and affiliate links.
• rel="ugc": For links in User-Generated Content like comments and forums.

Google now treats nofollow, sponsored, and ugc as hints rather than strict directives.

Run the tool on a blog’s recent posts to see if they offer dofollow backlinks. This helps set your expectations before pitching content.

Auditing Your Website

Ensure your blog comments and untrusted outbound links are marked nofollow. Confirm key links pass authority properly.

Verifying Link Purchases (With Caution)

If you’ve paid for placement, check that the publisher has added rel="sponsored" or nofollow to avoid violations.

Understanding Resource Pages

See which resources your competitors are endorsing with dofollow links. These could become valuable backlink targets for you.
