A page buried six clicks deep

You reached this in six clicks. A crawler would likely have stopped before now.

This far down, ranking is hard

This page sits five or more clicks from the homepage. That is deep enough that crawlers visit it rarely and pass it very little internal strength. If this were a product, an article, or a landing page you cared about, its position this far down would cap how well it can do.

How to fix a buried page

The fix is not to delete the pages in between. It is to add shortcuts. Link to important deep pages straight from hubs, category pages, or the main navigation, so they sit two or three clicks from home instead of six. A flatter structure tells search engines the page matters and gives it a real chance to rank.
