Crawl budget refers to the number of resources or pages a search engine crawler, such as Googlebot, allocates to crawl and index a website within a given timeframe. It represents the maximum number of URLs a search engine is willing to crawl on a website based on factors such as the website’s authority, freshness of content, server performance, and crawl demand.

Websites with higher crawl budgets are crawled more frequently, allowing search engines to quickly discover and index new or updated content.

Optimizing the crawl budget involves ensuring that important pages are accessible and crawlable, minimizing duplicate or low-quality content, and prioritizing content for indexing.
