Click depth refers to how many clicks it takes to reach a page from the homepage. Pages closer to the homepage (with shallow click depth) are more easily discovered and crawled by search engines. These pages are often perceived as more important, receiving more link equity. For affiliate sites, keeping key content—like reviews, comparisons, or money pages—within two or three clicks can improve their visibility in search results. A shallow site structure also enhances user experience, helping visitors find relevant content quickly. This can reduce bounce rates and improve engagement, which are positive behavioral signals for SEO. Therefore, managing click depth strategically supports better organic performance.
