Primary sourceGoogle Search Central documentation about nofollow, sponsored and ugc

How does nofollow work in practice?

Use rel=sponsored for advertisements and paid placements, rel=ugc for suitable user-generated links and nofollow when another link should not be endorsed.

  1. Classify the relationship: Distinguish editorial, paid, user-generated and untrusted links.
  2. Choose the specific value: Use sponsored or ugc when they fit and nofollow for other exceptions.
  3. Apply it to the link: Add the value to the rel attribute of the actual anchor element.
  4. Keep it useful: A qualified link can still be visible and valuable to the reader.
  5. Audit templates: Review ads, comments, partners and external widgets across the site.
nofollow explained through its main application, control and common mistake

How do you check nofollow?

Inspect the link element in rendered HTML and confirm that the attribute accurately describes the real relationship.

  • Paid placements use rel=sponsored or nofollow.
  • User links receive rel=ugc where appropriate.
  • Editorial source citations are not all automatically nofollowed.
  • The attribute appears on a real crawlable <a href> link.
  • Main internal navigation does not use nofollow for PageRank sculpting.
  • Combinations such as sponsored nofollow are separated correctly.

Which mistakes should you avoid with nofollow?

Do not use nofollow as a general method for directing internal authority or crawl budget. Important internal navigation should normally use standard crawlable links.

MistakeWhy it matters
Nofollowing every external linkNormal source citations are part of useful web content and do not require blanket rejection.
Treating nofollow as a blockGoogle treats the values as hints and can discover the destination through other routes.
Leaving paid links unmarkedThis hides the commercial relationship and can conflict with Google's link spam policies.

How do you audit nofollow links?

Review link relationships by template and content type. The desired outcome is correct qualification, not a particular percentage of nofollow links.
