<b>The over-optimization risk hiding in your own internal links</b>

External anchor profiles get audited obsessively; internal anchors get a free pass. That asymmetry is hard to justify on first principles. Internal links are the one anchor surface you fully control, which makes them both the easiest to optimize and the easiest to over-optimize.

There is a real mechanism here. If every internal link to a page uses the identical exact-match anchor, you are sending a maximally uniform, maximally repetitive signal — precisely the templated pattern the link-spam patents describe, except self-inflicted.

— External profiles get diversity for free, because many independent authors phrase things differently.
— Internal profiles get uniformity for free, because one templating system generates them all.

On one hand, internal anchors are a legitimate relevance signal and there is no public evidence of internal anchors triggering a Penguin-style action. On the other, the relevance value of internal anchors is widely accepted to plateau, and repetition past that plateau buys nothing while reducing entropy.

Limitation: I have seen no controlled study demonstrating internal-anchor over-optimization harm; the argument is mechanistic and analogical, not measured.

Open question: should internal anchor variation be planned with the same distribution discipline as external links, or is internal repetition simply inert above the relevance plateau?
