Crawl Depth in SEO: What is It & How to Improve It?  

Search engines utilize various criteria to determine the ranking of web pages in their search results. 

One such criterion is crawl depth, which denotes the number of clicks needed to reach a page on your website from the homepage through other pages. 

Comprehending crawl depth and its significance can assist website owners in refining their site navigation, boosting search engine visibility, and enhancing overall SEO performance.

This article will delve into the concept of crawl depth, its significance, and strategies to enhance your website’s crawl depth.

What is Crawl Depth?


The concept of Crawl Depth, or Indexation Depth, in Google, refers to the extent to which search engines catalog content. 

It measures the number of clicks required for a user to access a piece of content starting from the moment they land on a webpage.

The greater the number of clicks needed to reach the content, the higher the likelihood that the user will abandon the webpage. Understanding this metric not only aids in SEO optimization but also enhances the overall user experience.

Typically, four levels of depth are identified:

Level 0: the homepage

Level 1: primary categories

Level 2: subcategories

Level 3: individual products

These levels represent the depths that search engines should ideally reach. It is advisable not to exceed these levels as it could complicate navigation for users.

Why is Crawl Depth Important in SEO? 


Crawl depth holds significance in SEO for several reasons:

a. Efficient Indexing: Pages situated deep within a website’s hierarchy may not undergo crawling and indexing as frequently as those positioned closer to the homepage.

b. Link Equity: Pages in closer proximity to the homepage typically accrue more link equity (authority) from both internal and external sources. This can impact their search engine rankings and overall visibility.

c. User Experience: A convoluted and extensive website structure can complicate the process of locating crucial content for both users and search engines, potentially resulting in a subpar user experience.

c. Freshness: Pages with a shallow crawl depth are more prone to frequent crawling, enabling search engines to detect and index any updates or modifications promptly.

How does Google index a website?

  • When Google indexes a website, it relies on a process involving search engine crawlers, also known as web spiders. 
  • These bots visit newly created web pages, gathering and storing various types of information, including text, images, videos, and documents. 
  • Additionally, they record any hyperlinks found on these pages, which may lead to further exploration of linked content either immediately or at a later time.
  • The indexing process begins with the crawlers visiting web pages and storing them for future reference. 
  • When internal hyperlinks within these pages are encountered, they serve as signals to the crawlers that there is additional content to be indexed. 
  • Therefore, linking to a new page from existing pages on the website facilitates its eventual indexing by Google’s crawler.
  • To ensure optimal crawl depth and indexing coverage, it’s essential to establish internal linking throughout the website. 
  • This practice enables crawlers to navigate the site more efficiently, leading to a comprehensive indexing of its content. 
  • Without sufficient internal links, certain content may remain unindexed, resulting in diminished visibility within organic search results.
  • Alternatively, website owners can expedite the indexing process for new pages by directly submitting the URLs to Google. 
  • This can be done by performing a Google search for “submit URL to Google” and providing the URL of the new page in the submission field.

How often does Google crawl my website?

Google crawls websites with varying frequencies depending on their importance and relevance. For instance, prominent news websites undergo frequent crawling to ensure their content remains current, whereas smaller businesses may experience less frequent crawling.

The speed and performance of your website also influence crawl frequency. If your site experiences slowdowns or server issues, Google’s crawler may reduce its activity. It’s crucial to maintain a fast and easily accessible website to maximize visibility in organic search results.

How Can You Improve Your Website’s Crawl Depth?


Improving your website’s crawl depth entails optimizing its structure, internal linking, and URL hierarchy to ensure that crucial pages are closer to the homepage and readily accessible to search engine crawlers. Below are strategies outlined to enhance your website’s crawl depth:

a. Enhance Website Navigation and Structure

  • Enhance navigation menus and internal search features to facilitate users and search engine crawlers in locating important pages.
  • Use consistent and descriptive anchor text for internal links to indicate the destination page.
  • Ensure important pages are positioned closer to the homepage and reachable within a few clicks, avoiding burying them deep within the site’s architecture.

b. Increase Internal Links

  • Implement strategic internal linking across your website, ensuring that essential pages receive ample internal links from authoritative pages.
  • Distribute link equity to significant pages by incorporating relevant anchor text and contextually linking them from related pages.

c. Create an XML Sitemap and Optimize URLs

  • Develop an XML sitemap detailing your website’s structure and hierarchy, including crucial pages to facilitate easy discovery by search engine crawlers.
  • Optimize URL structures to reflect content and hierarchy, utilizing descriptive and keyword-rich URLs that are concise and comprehensible.
  • Employ a hierarchical URL structure to aid search engine crawlers in understanding your website’s organization.


Optimizing your website’s structure, internal linking, and other technical elements is crucial for ensuring that search engines discover and index your website’s content effectively. 

This optimization directly influences indexing efficiency, SEO performance, user experience, and the frequency of Googlebot revisiting your pages.
