Crawl Depth
Definition
Crawl depth refers to the extent to which a search engine spider explores the subpages of a website during the indexing process. For instance, a homepage which has a crawl depth of 0, will increase by 1 each time when you have to click a link to get to a subpage. Hence, a webpage that is only accessible by clicking four links in succession from the homepage will have a crawl depth of 4.
Crawl Depth Relevance For SEO
The concept of crawl depth is highly relevant for SEO because search engines favor sites with lower crawl depths. The more clicks required to access a page implies a deeper crawl depth, and the lower webpage relevance. If a webpage is not efficiently crawled and indexed, it might not appear in search engine results pages (SERPs), negatively affecting website visibility and organic traffic. Therefore, understanding and managing crawl depth is integral to effective SEO strategy.
Crawl Depth Best Practices for SEO
- Flat Website Architecture: Opt for a flat website architecture where each page is accessible within a few clicks from the home page. A flat architecture ensures lower crawl depth and easier navigation for both crawlers and users.
- Internal Linking: Make effective use of internal links to guide spiders through your website. A well-constructed internal linking strategy ensures that crawlers can reach deeper pages easily.
- Sitemap: Regularly update and submit your sitemap to search engines. This provides a roadmap for crawlers to follow, ensuring that your webpages get indexed.
- Avoid Broken Links: Broken links lead to dead ends for spiders. Regularly check for and fix broken links to ensure uninterrupted crawling.
