Free Crawl Budget Simulator
Estimate how efficiently search engines allocate crawl resources across your website.
Free Crawl Budget Simulator
See how efficiently search engines crawl your website and reclaim budget wasted on thin, duplicate, and parameterized URLs so Googlebot can discover more of your valuable content.
What Eats Your Free Crawl Budget
Parameterized URLs
Filtered product pages, sorted results, and session ID parameters create thousands of near-identical URLs that Googlebot explores individually, consuming enormous crawl budget while adding zero indexing value.
Blocked Important Pages
Overly aggressive robots.txt rules frequently block revenue-generating category pages, product pages, or blog posts that were meant to be indexed. Our simulator cross-references robots.txt rules against your sitemap URLs to expose this conflict.
Redirect Chains
Each redirect hop forces Googlebot to make an additional HTTP request. Multi-hop chains for http to https to www to canonical URL can reduce the effective crawl rate of your important pages by 50 to 70 percent.
How Google Allocates Crawl Budget
Crawl budget is determined by two factors: crawl rate limit (how fast Googlebot can crawl your site without overloading your server) and crawl demand (how many URLs Google wants to crawl based on popularity and freshness signals). Large sites — ecommerce stores, news sites, aggregators — routinely have more URLs than Google will crawl in a reasonable timeframe. Optimizing crawl budget means ensuring that every URL Googlebot visits is one worth indexing.
After identifying crawl waste with this free simulator, use our Free Robots.txt Tester to verify that your Disallow rules are correctly implemented and not inadvertently blocking critical pages.
