The over-optimization you control completely: internal anchors

The over-optimization you control completely: internal anchors

External anchor distribution is largely outside your control; internal anchor text is entirely within it — which is precisely why over-optimized internal linking is a self-authored failure mode. Sites that point every internal link at a money page with the identical exact-match anchor create a concentration no natural site would produce.

On one hand, internal anchors are a legitimate, strong relevance signal — arguably your clearest on-page statement of what a page is about. On the other, mechanical repetition of one commercial anchor across hundreds of templated internal links reads as manipulation, and unlike external links you cannot blame a third party.

The mistake is treating internal links as a free relevance lever with no distributional cost.

The fix:
— Vary internal anchors to the same target across descriptive, partial, and branded forms
— Audit templated internal links (related-posts modules, breadcrumbs, mega-menus) separately; templates create silent identical-anchor floods
— Reserve exact-match internal anchors for genuinely contextual in-body links, not navigation furniture

Limitation: internal anchor effects are hard to isolate experimentally, since you rarely change them in isolation.

Open question: are internal anchors evaluated under the same over-optimization logic as external ones, or treated as a distinct, more-trusted signal class with a higher tolerance threshold?
