Q: I keep adding pages to my biggest cluster, but rankings have plateaued. More content should mean more authority?

Short answer: not when you're adding redundant pages instead of filling actual gaps — past a point, more near-duplicate coverage adds dilution, not authority.

Once your cluster covers the topic well, the next ten "me too" articles overlap existing pages, compete for the same intents, and spread internal links thinner. The growth lever is no longer volume — it's coverage of what's still missing.

In practice:
— Run a gap analysis: list the subtopics and questions top competitors cover that you don't.
— Build pages for the genuine gaps, not more angles on what's already covered.
— Strengthen and consolidate existing pages instead of multiplying them.

The shift: early on, authority scales with coverage; later, it scales with depth and uniqueness. If adding pages stopped working, you've likely already covered the topic — now improve, don't inflate.
