How Crawl Depth Works

Crawl depth — also called click depth — is the number of clicks a user (or search engine bot) must make from the homepage to reach a specific page through internal links.

For e-commerce sites with deep category structures, this often requires deliberate internal linking strategies — linking from the homepage or high-authority category pages directly to important deep pages.

Do’s and Don’ts: Crawl Depth

✅ Do This ❌ Don’t Do This
✅ Submit your sitemap.xml to Google Search Console and keep it clean ❌ Ignore crawl errors — they waste crawl budget on dead pages
✅ Set canonical tags on duplicate and near-duplicate pages ❌ Leave both HTTP and HTTPS versions accessible without redirects
✅ Test your robots.txt before deploying to prevent blocking key pages ❌ Block JavaScript or CSS files in robots.txt — it breaks Google’s rendering
✅ Monitor Core Web Vitals monthly and fix regressions quickly ❌ Ignore page speed issues — slow pages lose rankings and conversions
