What is Link Depth (Crawl Depth)? How Many Clicks Is Too Many

What is Link Depth?

Link depth, also called click depth or crawl depth, is the number of clicks needed to reach a page from the homepage through internal links. The homepage has a depth of 0, pages linked from it have a depth of 1, pages linked from those have a depth of 2, and so on. A page that can only be reached after five or six clicks is "deep" in your site structure.

Link depth is a simple way to measure how accessible a page is, both for visitors and for search engine crawlers. The fewer clicks it takes to reach a page, the more likely it is to be crawled often and to receive link equity.

Why Link Depth Matters for SEO

• Crawling: search engine bots follow links. Pages close to the homepage are discovered and recrawled faster. Deep pages may be crawled rarely, which delays indexing of updates.
• Authority: authority flows from the homepage through links. Each extra level dilutes it, so deep pages receive less.
• Importance signal: a page that is hard to reach looks less important than one linked prominently.
• User experience: visitors give up when they need too many clicks to find what they want.

A common rule of thumb is to keep important pages within three clicks of the homepage. It is not an official limit, but it is a useful target.

Flat vs Deep Site Architecture

A flat site architecture keeps most pages within a few clicks of the homepage, with broad categories and many links between related pages. A deep architecture stacks many levels of categories and pagination, pushing content far from the homepage. Flat structures are easier to crawl and spread authority more evenly. The goal is not to link everything from the homepage, but to make sure no important page is buried.

How to Measure Link Depth

1. Crawl your site with an SEO crawler and sort pages by crawl depth.
2. Flag priority pages deeper than three clicks.
3. Look for pages reachable only through pagination ("page 7 of the blog"): they are often very deep.
4. Check for orphan pages: they have no depth at all because no link reaches them. Use our free orphan page checker to find them.

How to Reduce Link Depth

• Add contextual links from popular, shallow pages to deep priority pages.
• Create hub pages that link to every article of a topic.
• Improve category and collection pages so they link to all their items, not only the latest ones.
• Add breadcrumbs to give each page a short path back to its parent sections.
• Fix dead-end pages that have no outgoing links and stop crawlers.

Link Depth on Webflow, WordPress and Wix

• Webflow: collection lists are often limited to a number of items, so older CMS items fall out of every list and become deep or orphaned. Contextual links in Rich Text keep them reachable.
• WordPress: blog archives with pagination push older posts deeper every time you publish. Related posts and contextual links shorten those paths.
• Wix: blog feeds and dynamic pages follow the same pattern. Linking older posts from new ones keeps depth low.

Common Mistakes

• Relying on pagination as the only way to reach older content.
• Building many nested category levels with few items in each.
• Linking new pages only from a sitemap, which does not help depth for visitors.
