Crawl Budget
Quick Definition
Crawl budget is the number of pages a search engine bot will crawl on a website within a given timeframe. Large sites need to optimize crawl budget by ensuring important pages are prioritized and low-value pages are excluded.
Why It Matters
For small sites with under 1,000 pages, crawl budget is rarely an issue. But for large sites like e-commerce stores with millions of products, crawl budget optimization is critical. If Googlebot wastes time crawling unimportant pages, your important pages may not get indexed for weeks.
Real-World Example
An e-commerce site has 500,000 product pages but 2 million filter/sort URLs (like "shoes?color=red&size=10"). If those filter pages are not blocked in robots.txt, Googlebot spends most of its crawl budget on useless filter URLs instead of crawling actual product pages.
Signal Connection
Presence -- If Google cannot crawl and index your pages efficiently, they cannot appear in search results at all. Crawl budget optimization ensures your most important pages are present in Google index.
Pro Tip
Check your Crawl Stats report in Google Search Console (Settings > Crawl Stats). It shows how many pages Google crawls daily on your site. If the number is low relative to your total pages, you may have a crawl budget problem.
Common Mistake
Beginners worry about crawl budget on a 50-page blog. Crawl budget only becomes a real concern for sites with tens of thousands of pages or more. For small sites, focus on content quality and internal linking instead.
