For a small site, Google can easily crawl everything, so crawl budget is rarely a concern. It becomes important on large sites — big e-commerce catalogues, sites with millions of URLs, or those generating many parameter and faceted URLs — where Googlebot may not reach or refresh every page.
Budget is wasted by things a crawler shouldn't be spending time on: infinite filter combinations, duplicate URLs, redirect chains, soft 404s, and low-value pages. Efficient 304 responses, clean internal linking and a good sitemap help Google prioritise what matters.
The goal is to steer crawling toward pages you want indexed: consolidate duplicates with canonicals, block low-value paths, fix errors, and keep the site fast. This directly supports indexing — crawling is the step before a page can be indexed at all.

Frequently asked questions
No. For most small and medium sites Google crawls everything without issue. Crawl budget becomes a real concern on large sites — hundreds of thousands to millions of URLs, or heavy parameter/faceted navigation — where crawling efficiency affects how quickly pages are found and refreshed.
