Nofollow vs. Dofollow: When to Use Each for External Links

Nofollow vs. Dofollow

In the intricate dance of SEO, links are your currency, but not all links are created equal. The difference between a nofollow and dofollow link might seem small, but it’s the key to building trust with search engines, avoiding penalties, and maximizing your site’s authority. Let’s unravel when and how to use each, with real-world examples, Google’s latest guidelines, and a peek at how SEO Collabs simplifies ethical link-building.

  • Dofollow Links: The default. They pass “link equity” (SEO value) to the linked site, signaling trust to search engines.
  • Nofollow Links: Include the rel=”nofollow” attribute, telling search engines not to pass equity or associate your site with the linked page.

Google’s Golden Rule: Use nofollow for untrusted, paid, or user-generated content to avoid endorsing spam.

  • Example: A blog post reviewing a product you’re paid to promote.
  • Why: Google requires disclosure to prevent manipulative link schemes.
  • Code: <a href=”https://example.com” rel=”sponsored”>Best Coffee Maker</a>

2. User-Generated Content (UGC)

  • Example: Blog comments, forum posts, or social media links.
  • Why: Users could spam your site with low-quality links.
  • Code: <a href=”https://example.com” rel=”ugc”>Check this out</a>

3. Untrusted or Unvetted Sites

  • Example: Linking to a site you haven’t personally reviewed.
  • Why: Protect your site from associating with potential spam.

1. Editorial Endorsements

  • Example: Citing a peer-reviewed study in your article.
  • Why: Shows you trust the source, passing authority naturally.

2. Guest Posts on Trusted Sites

  • Example: A guest blog on a high-DA industry site.
  • Why: Strengthens your site’s relevance and authority.

3. Partner Collaborations

  • Example: Linking to a client’s case study on your portfolio.
  • Why: Ethical, mutual promotion with no paid exchange.

Google’s Guidelines: Updates You Can’t Ignore

  • 2019 Change: Nofollow became a “hint” rather than a directive, but still treat it as a rule.
  • New Attributes: Use rel=”sponsored” for paid links and rel=”ugc” for user-generated content.
  • Penalty Risk: Failing to nofollow paid links can lead to manual actions or lost rankings.

Strategic Use Cases

  • Case Study 1: A fashion blog uses nofollow for affiliate links but dofollow for a designer interview. Result? Higher rankings for non-sponsored content.
  • Case Study 2: A tech forum auto-adds ugc to user links, preventing spam penalties while fostering community.
