What Is Crawl Budget?
Crawl budget is the number of pages a search engine like Google will crawl on your website within a given timeframe, determined by your site’s crawl rate limit and crawl demand.
Why it matters
Crawl budget matters most for large websites (tens of thousands of pages). If crawlers waste time on duplicate URLs, broken links, or low-value pages, your important content may be crawled and updated less often. Optimizing crawl budget — by fixing redirects, removing duplicates, and blocking junk URLs — helps ensure Google spends its resources on the pages that actually matter.
Example
An online retailer with millions of faceted-navigation URLs (filters for size, color, price) can burn its entire crawl budget on near-duplicate pages, leaving new products undiscovered until the clutter is cleaned up.
How to optimize crawl budget
- Fix broken links and eliminate long redirect chains.
- Block low-value URLs (faceted navigation, internal search results) via robots.txt.
- Consolidate duplicate content with canonical tags.
- Keep your XML sitemap clean, current, and free of dead URLs.
- Improve site speed so crawlers can fetch more pages per visit.
