Ran into this repeatedly across orthopedic, gynecology, and fetal medicine client sites: multiple service/blog pages quietly competing for the same keyword, splitting rankings instead of stacking them.

What fixed it wasn't more content it was restructuring into a strict pillar-cluster architecture:

• One pillar page owns the head keyword

• Cluster pages get page-specific keyword variants only, mapped out before writing (not after)

• Every cluster page links back to the pillar, and the pillar links out to every cluster (bidirectional, not one-way)

• Before publishing anything new, we check it against existing pages for overlap and reassign the variant if there's a clash

Sounds obvious written out, but most sites (including client sites before we touched them) don't enforce the "before writing" part they map keywords after the content already exists, which is why cannibalization creeps back in every few months.
