Purpose first, rel second

Configure outbound links without blanket nofollow

Inventory external destinations, determine the editorial or commercial relationship and change shared templates only after approval. A useful ordinary link needs no restriction merely because it points to another domain.

Outbound links are sorted into editorial, sponsored, UGC and untrusted categories
Inventory → classify → attribute or removal → verify.

Message for a developer

“Export external links with source URL, anchor, destination, rel and target. Classify editorial, advertising, affiliate, UGC and suspicious links with the owner. Do not apply nofollow to every external URL. Check noopener for new tabs, then crawl again and test destinations.”

What to prepare

  • a backup of templates and content data;
  • advertising, affiliate and paid-placement lists;
  • comment and profile moderation rules;
  • representative pages and approval to remove disputed links.

Step-by-step

  1. Collect external <a href> elements with a crawler or CMS export.
  2. Review destinations, redirects, anchor text and placement.
  3. Leave useful unpaid editorial sources as ordinary links.
  4. Add sponsored to advertising and affiliate links and ugc to user-added links.
  5. Consider nofollow for an untrusted but reader-useful destination; remove unnecessary or harmful links.
  6. Use target="_blank" only intentionally and check noopener.
  7. Publish, clear caches, crawl again and manually test each category.

Markup examples

<a href="https://source.example/">Primary source</a>
<a href="https://partner.example/" rel="sponsored">Partner</a>
<a href="https://user.example/" rel="ugc nofollow">Profile</a>
<a href="https://docs.example/" target="_blank" rel="noopener">Document</a>

Compare values with Google's official guidance and MDN's noopener reference.

Risks, rollback and separate work

Bulk edits can affect affiliate tracking, analytics and user content. On error, restore the template or data backup and validate the register again.

Follow the verification guide. Compromise recovery, legal advertising disclosure, spam moderation and external-image replacement are separate tasks. For a large inventory, order the review.
