Crawl depth refers to the number of clicks it takes to get from a website’s homepage to any other page on the site. Pages with a high crawl depth are those that are buried deep within your site’s architecture, and this can be a significant issue for SEO. If a page is too many clicks away from the homepage, search engines may deem it less important, crawl it less frequently, and be less likely to rank it well in the search results.
Think of your website as a pyramid. Your homepage is the top, and your most important pages should be just one click away. The deeper a page is buried in the pyramid, the less important it appears to be. For a broader look at site architecture, see our guide on link structure.
Why a Shallow Site Architecture is Better for SEO
A flat, shallow site architecture is a cornerstone of good technical SEO. As explained in this guide to crawl depth from Search Engine Journal, a shallow architecture has several key benefits:
- Improved Crawlability: Pages that are closer to the homepage are crawled more frequently by search engines.
- Better Distribution of PageRank: A shallow architecture allows link equity to flow more efficiently from your high-authority pages to the rest of your site.
- Enhanced User Experience: A site that is easy to navigate is a better experience for users, which can lead to lower bounce rates and higher engagement.

Example: Improving Internal Linking
Imagine you have an important product page that is 5 clicks from the homepage. To reduce its crawl depth, you could:
- Add a link to it from your main navigation.
- Feature it on your homepage.
- Link to it from a relevant, high-authority blog post.
- Analyze Your Crawl Depth: Use an SEO audit tool like Creeper to crawl your site and identify pages with a high crawl depth.
- Prioritize Your Most Important Pages: Identify your key service pages, product pages, and cornerstone content. These are the pages you want to have a low crawl depth.
- Improve Your Internal Linking: Add internal links from your high-authority pages (like your homepage) to your deeper pages.
- Consider a Sitemap: A well-structured XML sitemap can help search engines to discover all of your pages, even if they have a high crawl depth.
Frequently Asked Questions
What is crawl depth?
Crawl depth is the number of clicks it takes to get from the homepage to a specific page on your website. A page with a high crawl depth is one that is buried deep within your site’s architecture, requiring many clicks to reach.
Why is high crawl depth bad for SEO?
High crawl depth is bad for SEO because it makes it harder for search engines to discover and index your content. It also signals that the page is less important, as it is not easily accessible from the main pages of your site. This can lead to lower rankings and less organic traffic.
How can I reduce the crawl depth of my pages?
The best way to reduce crawl depth is to improve your internal linking structure. Make sure that your important pages are linked to from your homepage and other high-authority pages. You can also use a flat site architecture, where most pages are only a few clicks away from the homepage.
