<b>Anchor sculpting with nofollow: why the old math is broken</b>

A generation of practitioners learned to 'sculpt' anchor equity by nofollowing internal links — the idea being that flow would concentrate on the followed ones. That model has been dead since 2009, yet its ghost still shapes how people think about anchors.

The original PageRank-flow story let you redistribute a page's outbound value by marking some links nofollow. Google closed that loophole: a nofollowed link still consumes its share of the outflow; that share simply evaporates rather than redirecting. Then in 2019 nofollow shifted from a directive to a 'hint,' adding further ambiguity to whether the link — and its anchor — is even discounted.

— Old mental model: nofollow = anchor signal redirected elsewhere.
— Current reality: nofollow = anchor signal possibly still read, value possibly still consumed, treated as a hint.

On one hand, the 2019 change means a nofollow anchor may now contribute relevance signals it previously would not. On the other, Google has never quantified the hint, so we cannot model the contribution.

Limitation: 'hint' is deliberately underspecified, and behavior may differ across nofollow, sponsored, and ugc attributes in ways no public test cleanly separates.

Open question: if nofollow anchors are now sometimes read for relevance, does the attribute belong in your distribution math at all — or has it become noise we are still treating as signal?
