Nofollow, Sponsored and UGC

Nofollow, sponsored, and ugc are link attributes that help website operators identify the relationship with linked pages more cleanly.

Briefly explained • Updated: 01.09.2026 • Reading time: about 4 minutes.

The attributes rel="nofollow", rel="sponsored" and rel="ugc" give search engines clues about the character of a link. They help rank advertisements, paid placements, user-generated content, and non-editorially verified links.

What does Nofollow, Sponsored and UGC mean?

The attributes rel="nofollow", rel="sponsored" and rel="ugc" give search engines clues about the character of a link. They help rank advertisements, paid placements, user-generated content, and non-editorially verified links.

The attributes do not replace a clean link policy. They are a technical signal that becomes especially important in advertising, affiliate links, comments, forums and external recommendations.

When the topic becomes important in practice

Nofollow, Sponsored and UGC becomes particularly relevant when visibility must be evaluated not only technically, but also strategically.

Marking advertising

Paid links or sponsorship should be marked sponsored.

Separating UGC cleanly

Comments, forum posts or user profiles can be classified better with ugc.

Secure unchecked links

Nofollow can be useful if one side does not want to stand for the goal.

Important signals

  • rel="sponsored" for paid or promotional links
  • rel="ugc" for user-generated content
  • rel="nofollow" for links that are not editorially recommended
  • clear moderation and labelling rules for external links

Typical errors

  • All outgoing links are set flat on nofollow and thus invalidate editorial signals.
  • Do not label paid links as sponsored.
  • Publish UGC areas without moderation and without matching link attributes.
Link marking

The three attributes solve different problems

Nofollow, sponsored and ugc are often called together, but have different tasks. Sponsored identifies paid or promotional links. UGC identifies user-generated content such as comments or forum posts. Nofollow fits if a page does not want to be associated with the target or if other values do not apply.

Important is the clean relationship with the link goal. An editorially set, helpful source link usually does not need an attribute. A paid link, on the other hand, should not act as an independent recommendation.

Sponsored

For advertising, sponsorship, advertorials or paid placements.

ugc

For comments, forums, reviews and other user-generated areas.

nofollow

For unrecommended or unchecked links, if no more suitable labelling applies.

Practical example

A blog with guest posts, comments and affiliate links

A magazine publishes editorial articles, paid affiliate contributions, comments, and affiliate references. Without clear rules, mixed signals quickly emerge: an affiliate link remains follow, an editorial source link becomes unnecessarily nofollow, and comments link to the outside world unchecked.

A clean link policy defines standard values per area. Editorial sources remain normal, advertising and affiliate contexts get sponsored, comments get ugc and risky user links additionally nofollow.

  • Testing: What types of links are there on the website?
  • Testing: Which of these are paid, sponsored or affiliate-related?
  • Testing: Which links are created by users?
  • Testing: Where is an editorial recommendation really wanted?
  • Testing: Are templates, CMS components and old content consistently updated?
Audits

Check link attributes in the template

Most errors do not arise in individual articles, but in templates: comment component, author box, affiliate block, sponsored teaser, partner logo or footer directory. Therefore, an audit should not only check URLs, but page types.

Particularly important is the combination of HTML output and editorial rule. If the CMS can be sponsored, but editors have no clear specification, the problem remains.

Template cover Which components automatically generate external links?
Compliance with the rules Are paid, user-generated and editorial links distinguishable?
Old stock Were older partner, affiliate or community areas followed up?
Governance

Link attributes need editorial rules

Technically, rel attributes can be set quickly. More difficult is the editorial decision behind it. Teams need to know which links are paid, which are from users and which are deliberately set as an editorial recommendation.

Without such rules, inconsistencies arise: the same partner link is sponsored on one side and followed on another, forum links are not marked or all external sources are set flat-rate nofollow. A small guide for editors prevents many of these mistakes.

Policy

Short rule per link type: editorial, paid, UGC, unchecked.

Templates

CMS components automatically set standard attributes correctly.

Review

Regular sample for old content, guest posts and partner pages.

  • Testing: Is there a documented link policy for editors?
  • Testing: Are affiliate and sponsorship components technically clearly marked?
  • Testing: Are UGC areas moderated and appropriately awarded?
  • Testing: Do real editorial source links remain follow if they are consciously recommended?
  • Testing: Will the policy be re-examined for relaunches and template changes?

SEO classification

Do not consider it isolated

Nofollow, Sponsored and UGC works best when content, technology, internal linking and external signals go hand in hand.

Making measurable

Concrete URL sets, search console data, SERP observation and clear priorities instead of general SEO lists make sense.

Use as a cluster

The term should be internally linked to matching wiki, tool, reference and performance pages.
