Page Depth
The number of clicks required to reach a page from the homepage. Also called "crawl depth." Pages deeper than 3–4 clicks receive less crawl frequency from Googlebot and less internal link equity from the homepage.
Definition
Page depth (also called crawl depth or click depth) is the minimum number of hyperlink clicks required to navigate from the homepage to a given page. The homepage has a depth of 0; a page directly linked from the homepage has a depth of 1; a page linked from a depth-1 page has a depth of 2; and so on. Page depth matters for SEO because: (1) **Crawl frequency** — Googlebot follows links to discover pages. Pages at greater depth require more link-following steps to reach and are therefore crawled less frequently. For large sites, pages at depth 5+ may be crawled rarely or not at all, depending on crawl budget. (2) **Internal link equity flow** — link equity flows through links. Each link hop dilutes the equity passed (a page at depth 4 receives equity that has passed through 4 links from the homepage, with each link distributing it among multiple outbound links). Pages at greater depth receive less internal equity. (3) **User navigation** — deep page hierarchies are harder to navigate and can increase bounce rates if users can\'t find relevant content without many clicks. Industry guidance for important pages: keep them within 3–4 clicks from the homepage. For very large sites with millions of pages (e-commerce, news), creative use of sitemaps, internal linking, and hub pages can partially mitigate depth issues for important page types.
Why it matters for SEO
Page depth is one of the primary reasons important pages on large sites underperform relative to their content quality. A high-quality product page buried 6 clicks deep in a category hierarchy will be crawled less frequently and carry less internal equity than an equivalent page at depth 2. Reducing page depth for high-priority pages — through improved navigation, hub pages, or internal link additions — directly improves crawl frequency and equity for those pages.
How DeepSEOAnalysis checks this
The audit maps the crawl depth of every page discovered during the crawl, starting from the submitted URL (treated as depth 0). Pages discovered only at depth 4+ are flagged as potentially under-crawled, especially if they are content pages (blog posts, product pages, landing pages) rather than utility pages (privacy policy, terms). Orphan pages — pages not linked from any other crawled page — are flagged as a critical issue (Googlebot cannot discover them through crawling at all, making sitemap submission the only discovery mechanism).

Link Equity (PageRank)
The ranking value passed from one page to another through hyperlinks — derived from Google\'s original PageRank algorithm. Pages with more or higher-quality inbound links have more link equity and pass more equity to pages they link to. Also called "link juice."
