Nofollow links: what they mean, and when to use sponsored or UGC instead

A nofollow link has rel="nofollow" in its HTML, telling search engines not to treat it as an endorsement. Google also supports rel="sponsored" for paid or affiliate links and rel="ugc" for user-generated content like comments. Google treats all three as hints. Nofollow links pass little ranking value but can still bring visitors and brand awareness.

The guest post that sold a followed link

A Kochi agency paid ₹8,000 for a guest post on a marketing blog, expecting an SEO boost. The link was followed and the article was clearly paid.

A few months later the blog was hit for selling links and the link’s value disappeared.

The agency now marks paid placements as sponsored and judges them on referral traffic and leads, not link value.

Illustrative example based on a common pattern in Kerala e-commerce accounts. Numbers rounded.

What nofollow is

Normal links can pass ranking signals. Adding rel attributes tells Google about the relationship: nofollow (don’t endorse), sponsored (paid or affiliate), ugc (posted by users).

Google uses these as hints, so it may still use them for discovery. For your own site, mark paid and affiliate links as sponsored to stay within Google’s rules.

Nofollow links can bring real visitors, brand searches and later followed links.
Hints, not rules
Google may still crawl or use nofollow links.

Mistakes to avoid

    Important pages get less internal authority.

    Risk of manual action for link spam.
