You are 1 click deep
The buried page is further down than it should be. Keep going.
Why click-depth matters
Search engines spend more crawl budget on pages close to the homepage and less on pages behind many clicks. Depth is a rough measure of importance. If it takes six clicks to reach a page, the site's own structure is saying the page barely matters. Content you care about should not be that far down.
The only way on
This page exists to add one more level of depth to the chain. There is exactly one link forward, below, and no shortcut from anywhere closer to the top. That is how a real site can leave an important page buried behind a single narrow trail of links.
