You don't calculate crawl budget with a formula. Instead, you measure how many pages Googlebot actually crawls daily by checking Google Search Console under Settings > Crawl Stats. This shows your crawl requests per day over the past 90 days. That's your effective crawl budget. Google determines crawl budget based on two factors: crawl rate limit (how fast your server can handle requests without degrading) and crawl demand (how valuable Google thinks your content is and how often it changes). If you have 50,000 pages but Google only crawls 800 per day, you have a crawl budget problem. If you have 2,000 pages and Google crawls 1,500 daily, you're fine. For most sites under 10,000 indexed pages with normal update frequency, crawl budget is irrelevant. Google will crawl everything that matters. You only need to optimize crawl budget if you run a large site (50,000+ URLs), publish hundreds of new pages daily, or notice important pages going weeks without being crawled. To maximize your existing crawl budget: - Block low-value URLs in robots.txt (search result pages, filters, session IDs) - Fix redirect chains and broken links that waste crawl on errors - Use XML sitemaps to guide Googlebot to priority pages - Improve server response time—faster sites get crawled more - Reduce duplicate and thin content that dilutes crawl attention At Ottawa SEO, we see crawl budget issues mainly on e-commerce sites with 100,000+ product variations or news sites publishing 200+ articles daily. For a typical business site with 500 pages and monthly updates, obsessing over crawl budget is premature optimization. Focus on site speed, internal linking, and content quality first. Check your crawl stats quarterly, and only intervene if you see critical pages being ignored for 30+ days while Google wastes crawls on junk URLs.
