Crawl budget is the number of pages a search engine will crawl on your site within a given timeframe, determined by crawl rate limit (how fast Googlebot can crawl without overloading your server) and crawl demand (how much Google wants to crawl based on popularity and freshness).
Why Crawl Budget matters for SEO
If your crawl budget is wasted on low-value pages (parameter URLs, faceted navigation, duplicate content), Google may never discover or re-crawl your most important pages. Sites with over 10,000 pages are most affected. Wasted crawl budget means slower indexation of new content and delayed ranking updates.
Pro tip on Crawl Budget
Block low-value URLs in robots.txt. Fix redirect chains (each hop consumes crawl budget). Remove or noindex thin/duplicate pages. Ensure your XML sitemap only includes canonical, indexable URLs. Improve server response times (faster responses = more pages crawled per visit).
Crawl Budget vs Crawl Rate
Crawl budget is how many pages Google will crawl. Crawl rate is how fast it crawls them. You can have a high crawl rate but low crawl budget if most pages aren't worth crawling.
