The deeper a page is buried, the less Google cares about it
Crawl depth is the number of clicks it takes to reach a page from the homepage. A page at depth 1 is linked directly from the homepage. A page at depth 5 requires five clicks to reach.
This matters because Google interprets depth as importance. Pages close to the homepage are assumed to be important. Pages buried six levels deep? Probably not.
How depth affects SEO
Crawl frequency drops. Google's crawl budget is limited. It prioritizes pages closer to the surface. Deep pages might get crawled once a month — or never.
Link equity thins out. Each level of depth dilutes the ranking power flowing from the homepage. By depth 5, there's barely any left.
Users can't find the content. If it takes 6 clicks to reach a product page, most users will give up before they get there. More likely they'll just use the search bar — or leave.
What's a healthy crawl depth?
| Depth | Status |
|---|---|
| 1-2 clicks | Excellent — Google crawls these frequently |
| 3 clicks | Good — the practical maximum for important pages |
| 4 clicks | Acceptable for less critical content |
| 5+ clicks | Problematic — reduced crawling, minimal authority |
The rule of thumb: every important page should be within 3 clicks of the homepage.
What pushes pages too deep
Flat structures gone wrong. A site with thousands of products listed 100 per page means products on page 10 are at depth 10+.
Blog archives. Chronological blog pages push older content deeper and deeper over time.
Nested categories. Category → Subcategory → Sub-subcategory → Product creates unnecessarily deep paths.
Missing hub pages. Without landing pages that aggregate and link to related content, individual pages sink.
How to reduce crawl depth
Create hub pages. A "topic hub" that links to all related articles keeps everything at depth 2-3.
Use breadcrumbs. They add internal link paths that flatten the structure.
Add links from popular pages. Your homepage, top blog posts, and most-visited pages should link to important deeper content.
Review pagination. If paginated lists bury content, consider adding "jump to page" links or increasing items per page.
How to audit crawl depth
You need a crawler that maps your entire site and calculates the shortest path from the homepage to every page:
- Report the crawl depth of each page
- Flag pages at depth 4+
- Identify clusters of deep pages
- Show which pages link to deep content (to find missing link opportunities)
Kaitico calculates the crawl depth of every page during an audit, flagging content buried too deep and helping you flatten your site structure.
