Link Attribute Builder

Build an HTML link with the right rel attributes for paid, user-generated or untrusted links.

Link URL

Anchor text

What kind of link is it?

sponsoredPaid placements, ads and affiliate links. Required by Google for anything you were paid for.

nofollowYou don’t want to vouch for the page. Also a safe extra for paid links to cover older crawlers.

ugcLinks inside user-generated content: comments, forum posts, reviews.

noopenerSecurity: stops the opened page controlling your tab. Browsers imply it for target=_blank, but it’s harmless to add.

noreferrerHides your page as the referrer — the other site won’t see the visit came from you in analytics.

Open in a new tab (target="_blank")

Title attribute (optional)

HTML

Markdown

Google’s rules: mark paid and affiliate links rel="sponsored" and links in comments or forums rel="ugc"; you can combine values like rel="sponsored nofollow". Normal editorial links to sources you trust need no rel at all — they pass ranking signals, which is what you want for good references. Markdown can’t carry rel attributes, so use the HTML version on CMSs that support it.

Frequently asked questions

What is the difference between nofollow, sponsored and ugc?

sponsored marks paid and affiliate links, ugc marks links in comments and forums, and nofollow is for any link you don’t want to endorse. Google treats them all as hints.

Should affiliate links be nofollow?

Google asks for rel="sponsored" on affiliate and paid links. Adding nofollow as well is fine for older crawlers.

What does noopener do?

It stops the page opened in a new tab from accessing your page through window.opener, which prevents a class of security attacks.
