# Crawl depth

**Crawl depth**, also called click depth, is the number of link steps between a starting point and a URL. The starting point is usually the homepage. In this counting the homepage has depth 0, and a page linked directly from it has depth 1. Some tools count the homepage as depth 1. SEO crawlers report the value for every URL they find.

## Why does crawl depth matter?

Pages with a long link path are harder to find. Google can only follow links written as `<a>` elements with an `href` attribute, so a page that exists only behind script-driven navigation has no usable path at all.

According to reports, Google's John Mueller said in a 2018 hangout that Google does not count slashes in URLs. What matters a little is how many clicks it takes to reach a page from the homepage. According to Search Engine Journal's report, a page one click away signals more relevance than a page several clicks away. Google does not name a maximum depth.

Crawl depth is therefore different from URL path depth. `/a/b/c/d/` can sit one click from the homepage, and `/product-x/` can be four clicks away.

## Example

Homepage (0) → category (1) → subcategory (2) → product list page 3 (3) → product (4). A product reachable only through pagination sits deep. A link from the category page or from a bestseller list shortens the path to 2.

*Diagram: Site architecture and click depth.* Each level sits one click further from the home page. Google finds pages mainly through links and recommends that every page you care about gets a link from at least one other page on the site. The breadcrumb shows the page’s position in the hierarchy.
